WTI's NBB series Network Power Switches allow secure, remote management of AC powered rack mount equipment via SSL, SSH, SNMP, web browser, telnet, external modem or local terminal. NBB series units provide the ability to perform power reboot and power switching functions and automatically notify you when changes in rack temperature, ping command response, invalid access attempts, circuit breaker status and other factors are detected.
In addition to these power management and alarm functions, NBB models also include the ability to monitor power to your equipment, and automatically notify you when changes in current consumption exceed user-defined threshold values. Security and Co-Location Features:
Secure Shell (SSHv2) encryption and address-specific IP security masks help to prevent unauthorized access to command and configuration functions. The NBB provides four different levels of security for user accounts: Administrator, SuperUser, User and ViewOnly. The Administrator level provides complete access to all plug functions, operating features and configuration menus. The SuperUser level allows switching and rebooting of all plugs but does not allow access to configuration functions. The User level allows access to only a select group of Administrator-defined plugs. The ViewOnly level allows you to check plug status and unit status, but does not allow switching or rebooting of outlets or access to configuration menus.
NBB units also include full Radius support, LDAP capability, TACACS capability, MIB capability, DHCP and an invalid access lockout feature. An Audit Log records all user access, login and logout times and command actions.
Current and Power Metering:
NBB series units can measure and report current and power consumption trends. If the NBB detects that user defined thresholds for current consumption have been exceeded the unit can provide prompt notification to network administrators and IT personnel. The NBB also records current consumption data to a convenient log file, which can be retrieved in ASCII, XML, or CSV format or displayed in graph format.

displayed. When this parameter is defined, the serial number can be displayed via the Product Status screen in the Web Browser or by invoking the /J* command in the Text Interface. Since the serial number plate on the NBB unit is not always easily accessible after installation, it is often helpful to define the serial number here in order to simplify the process of determining the serial number later. (Default = undefined.) 5.3.1. The Real Time Clock and Calendar
The Real Time Clock menu is used to set the NBB internal clock and calendar. The
configuration menu for the Real Time Clock offers the following options:
• Date: Sets the Month, Date, Year and day of the week for the NBB real-time clock/
• Time: Sets the Hour, Minute and Second for the NBB real time clock/calendar. Key
in the time using the 24-hour (military) format.
• Time Zone: Sets the time zone, relative to Greenwich Mean Time. Note that the
Time Zone setting will function differently, depending upon whether or not the NTP feature is enabled and properly configured. (Default = GMT (No DST).) NTP Enabled: The Time Zone setting is used to adjust the Greenwich Mean
Time value (received from the NTP server) in order to determine the precise local time for the selected time zone.
NTP Disabled: If NTP is disabled, or if the NBB is not able to access the NTP
server, then status screens and activity logs will list the selected Time Zone and current Real Time Clock value, but will not apply the correction factor to the displayed Real Time Clock value.
• NTP Enable: When enabled, the NBB will contact an NTP server (defined via the
NTP Address prompts) once a day, and update its clock based on the NTP server time and selected Time Zone. (Default = Off.) • The NBB will also contact the NTP server and update the time whenever you change NTP parameters. • To cause NBB to immediately contact the NTP server at any time, make certain that the NTP feature is enabled and configured, then type /F and
press [Enter]. When the System Parameters menu appears, press [Esc].
The NBB will save parameters and then attempt to contact the server, as
specified by currently defined NTP parameters.
• Primary NTP Address: Defines the IP address or domain name (up to 64
characters long) for the primary NTP server. (Default = undefined.) • In order to use domain names for web addresses, DNS parameters must first be defined as described in Section 5.9.5. • The Web Browser Interface includes two separate fields that are allowed to define both an IPv4 protocol and IPv6 protocol format Primary NTP Address and Secondary NTP Address. • When the Primary NTP Address and Secondary NTP Address are defined via the Text Interface, the NBB will display a prompt that instructs the user to select IPv4 or IPv6 protocol. • The NBB allows parameters for both IPv4 and IPv6 protocols to be defined and saved. • Secondary NTP Address: Defines the IP address or domain name (up to 64
characters long) for the secondary, fallback NTP Server. (Default = undefined.) • In order to use domain names for web addresses, DNS parameters must first be defined as described in Section 5.9.5. • The Web Browser Interface includes two separate fields that are allowed to define both an IPv4 protocol and IPv6 protocol format Primary NTP Address and Secondary NTP Address. • When the Primary NTP Address and Secondary NTP Address are defined via the Text Interface, the NBB will display a prompt that instructs the user to select IPv4 or IPv6 protocol. • The NBB allows parameters for both IPv4 and IPv6 protocols to be defined and saved. • NTP Timeout: The amount of time in seconds, that will elapse between each
attempt to contact the NTP server. When the initial attempt is unsuccessful, the NBB will retry the connection four times. If neither the primary nor secondary NTP server responds, the NBB will wait 24 hours before attempting to contact the NTP server again. (Default = 3 Seconds.) • Test NTP Servers: Allows you to ping the IP addresses or domain names defined
via the Primary and Secondary NTP Address prompts, or to ping a new address or domain defined via the Test NTP Servers submenu in order to check that a valid IP address or domain name has been entered.
• In order for the Test NTP Servers feature to function, your network and/or firewall must be configured to allow ping commands. • In addition to the Test NTP Servers option, the /TEST command in the Text Interface or the "Test" option in the Web Browser Interface can also be used to ping any user defined IP address in order to make certain that the IP address is responding. 5.3.2. The Invalid Access Lockout Feature
When properly configured and enabled, the Invalid Access Lockout feature can watch
all login attempts made via SSH connection, Telnet connection, web browser or the
serial SetUp Port. If the counter for any of these exceeds the user-defined threshold for
maximum invalid attempts, then the corresponding port or protocol will be automatically
disabled for the length of time specified by the Lockout Duration parameter.
When Invalid Access Attempt monitoring is enabled for the serial SetUp Port, the NBB will count invalid access attempts at the serial SetUp Port. If the number of invalid access attempts exceeds the defined Lockout Attempts trigger value, the NBB will lock the serial SetUp Port for the defined Lockout Duration period. When Invalid Access Attempt monitoring for SSH, Telnet or Web are selected, a lockout will be triggered when the number of invalid access attempts during the defined Lockout Duration period exceeds the defined Hit Count for the protocol. For example, if the SSH Hit Count is set at 10 and the SSH Lockout Duration period is set at 120 seconds, then if over 10 invalid access attempts are detected within 120 seconds, the NBB will then lock out the MAC address that generated the excessive attempts for 120 seconds.
Note that when an Invalid Access Lockout occurs, you can either wait for the Lockout
Duration period to elapse (after which, the NBB will automatically reactivate the port or
protocol), or you can issue the /UL command (type /UL and press [Enter]) via the Text
Interface to instantly unlock all NBB logical network ports and communication protocols.
• When the Serial Port Invalid Access Lockout Alarm has been enabled as described in Section 7.6, the NBB can also provide notification via email, Syslog Message, and/or SNMP trap whenever an Invalid Access Lockout occurs at the serial SetUp Port. • If the Network Port has been locked by the Invalid Access Lockout feature, it will still respond to the ping command (providing that the ping command has not been disabled at the Network Port.) The Invalid Access Lockout configuration menus allow you to select the following parameters: • Serial Port Protection: Enables/Disables the Invalid Access Lockout function for
the serial SetUp Port and selects lockout parameters. When this item is enabled and excessive Invalid Access attempts are detected at the SetUp Port, the SetUp Port will be locked until the user-defined Lockout Duration period elapses, or until the /UL command is issued.
• Serial Port Protection: Enables/Disables the Invalid Access Lockout feature for
the serial SetUp Port. (Default = Off.) • Lockout Attempts: The number of invalid attempts that must occur in order to
trigger the Invalid Access Lockout feature at the serial SetUp Port. (Default = 9.) • Lockout Duration: This option selects the length of time that the serial SetUp
Port will remain locked when Invalid Access Lockout occurs. If the duration is set at "Infinite", then ports will remained locked until the /UL command is issued. (Default = 30 Minutes.) • SSH Protection: Enables/Disables and configures the Invalid Access function
for SSH connections. When this item is enabled and excessive Invalid Access Attempts via SSH are detected, then the NBB will lock out the offending MAC address for the user-defined SSH Lockout Duration Period or until the /UL command is issued. Note that for SSH protection, the lockout trigger is a function of the SSH Hit Count parameter and the SSH Lockout Duration Parameter.
• Lockout Enable: Enables/Disables Invalid Access Lockout protection for SSH
connections. (Default = Off.) • SSH Hit Count: The number of invalid attempts that must occur during the
length of time specified by the SSH Lockout Duration period in order to trigger the Invalid Access Lockout feature for SSH protocol. For example, if the SSH Hit Count parameter is set to 10 and the SSH Lockout Duration parameter is set to 30 minutes, then the NBB will lock out the offending MAC address for 30 minutes when over 10 invalid access attempts occur during any 30 minute long period. (Default = 40.) • SSH Lockout Duration: This option selects both the length of time that an SSH
Lockout will remain in effect and also the time period over which invalid access attempts will be counted. When an SSH Lockout occurs, the offending MAC address will be prevented from establishing an SSH connection to the NBB for the defined SSH Lockout Duration period. (Default = 120 Seconds.) • Telnet Protection: Enables/Disables and configures the Invalid Access function
for Telnet connections. When this item is enabled and excessive Invalid Access Attempts via Telnet are detected, then the NBB will lock out the offending MAC address for the user-defined Telnet Lockout Duration Period or until the /UL command is issued. Note that for Telnet protection, the lockout trigger is a function of the Telnet Hit Count parameter and the Telnet Lockout Duration Parameter.
• Lockout Enable: Enables/Disables Invalid Access Lockout protection for Telnet
connections. (Default = Off.) • Telnet Hit Count: The number of invalid attempts that must occur during
the length of time specified by the Telnet Lockout Duration period in order to trigger the Invalid Access Lockout feature for the Telnet protocol. For example, if the Telnet Hit Count parameter is set to 10 and the Telnet Lockout Duration parameter is set to 30 minutes, then the NBB will lock out the offending MAC address for 30 minutes when over 10 invalid access attempts occur during any 30 minute long period. (Default = 20.) • Telnet Lockout Duration: This option selects both the length of time that a
Telnet Lockout will remain in effect and also the time period over which invalid access attempts will be counted. When a Telnet Lockout occurs, the offending MAC address will be prevented from establishing a Telnet connection to the NBB for the defined Telnet Lockout Duration period. (Default = 120 Seconds.) • Web Protection: Enables/Disables and configures the Invalid Access function
for Web connections. When this item is enabled and excessive Invalid Access Attempts via Web are detected, then the NBB will lock out the offending MAC address for the user-defined Web Lockout Duration Period or until the /UL command is issued. Note that for Web protection, the lockout trigger is a function of the Web Hit Count parameter and the Web Lockout Duration Parameter.
• Lockout Enable: Enables/Disables Invalid Access Lockout protection for web
connections. (Default = Off.) • Web Hit Count: The number of invalid attempts that must occur during the
length of time specified by the Web Lockout Duration period in order to trigger the Invalid Access Lockout feature for Web access. For example, if the Web Hit Count parameter is set to 10 and the Web Lockout Duration parameter is set to 30 minutes, then the NBB will lock out the offending MAC address for 30 minutes when over 10 invalid access attempts occur during any 30 minute long period. (Default = 80.) • Web Lockout Duration: This option selects both the length of time that a Web
Lockout will remain in effect and also the time period over which invalid access attempts will be counted. When a Web Lockout occurs, the offending MAC address will be prevented from establishing a Web connection to the NBB for the defined Telnet Lockout Duration period. (Default = 60 Seconds.) 5.3.3. Log Configuration
This feature allows you to create records of command activity, alarm actions,
temperature readings and current and power consumption for the NBB unit. The Log
features are enabled and configured via the System Parameters Menus.
• Audit Log: Creates a record of all power switching at the NBB unit, including
reboots and switching caused by Load Shedding, Load Shedding Recovery, Ping No Answer Reboots and Scheduled Reboots. Each Log record includes a description of the activity that caused the power switching, the username for the account that initiated the power switching or reboot and the time and date that the power switching or reboot occurred. In addition to power switching activity, the Audit Log will also include login/logout activity for each user account.
• Alarm Log: Creates a record of all Alarm Activity at the NBB unit. When an alarm
is triggered, the NBB will generate a record that lists the time and date of the alarm, the name of the Alarm triggered, and a description of the Alarm.
• Current Metering Log: Provides a record of current consumption. Log records
include the time and date, current and voltage readings and temperature readings. Current Metering Log data can be downloaded in ASCII, CSV or XML format.
5.3.3.1. Audit Log and Alarm Log Configuration OptionsThe Log Configuration options in the System Parameters menu allows you to enable/disable and configure the Audit Log and Alarm Log. The Audit Log and Alarm Log both offer the following parameters: • Off: The Log is disabled, and command activity and/or alarm events will not be
• On - With Syslog: The Log is enabled, and power switching, login/logout activity
and/or alarm events will be logged. The NBB will generate a Syslog Message every time a Log record is created. • On - Without Syslog: The Log is enabled, and power switching, login/logout
activity and/or alarm events will be logged, but the NBB will not generate a Syslog Message every time a Log record is created. (Default Setting.) • In order for the Audit Log or Alarm Log to generate Syslog Messages, Syslog Parameters must first be defined as described in Section 11. • The Audit Log will truncate usernames that are longer than 22 characters, and display two dots (.) in place of the remaining characters. 5.3.3.2. Reading, Downloading and Erasing LogsTo read or download the status logs, proceed as follows: • Text Interface: Type /L and press [Enter] to access the Display Log menu. In the
Text Interface, the Display Logs menu is used to download or display the Audit Log and Alarm Log as well as the Current Metering Log and Power Metering Log.
• Web Browser Interface: Move the cursor over the "Current Metering," "Power
Metering" or "Logs" link. When the flyout menu appears, click on the desired option and then follow the instructions in the resulting submenu.
Note: You can also display current readings via the Current Metering function.
In the Text Interface, type /M and then press [Enter].
Proceed as follows to download, display or erase logged data: • Audit Log and Alarm Log: The Audit Log and Alarm Log can be displayed or
downloaded via either the Text Interface or Web Browser Interface. When the Audit Log or Alarm Log are displayed via the Text Interface, the NBB will also offer the option to erase Audit Log or Alarm Log data.
• Current Metering Log and Power Metering Log: The Current Metering Log and
Power Metering Log can be displayed or downloaded via either the Text Interface or Web Browser Interface. When the Current Metering Log is selected via the Text Interface, the NBB will also offer the option to erase Current Metering Log data. • Temperature data is included in the Current History Log.
• When the Current Metering Log is erased, the Power Metering Log will also be erased. • The NBB dedicates a fixed amount of internal memory for log records, and if log records are allowed to accumulate until memory is filled, data will eventually "wrap around," and older data will be overwritten by newer data. • Note that once records have been erased or overwritten, they cannot be recovered. 5.3.3.3. Current Metering Log Display OptionsWhen the Current Metering Log (or Current History) is displayed, the NBB offers the option to display Current Metering data for either the entire unit or for an individual line. In addition, the Web Browser Interface also allows you to view Current Metering data and can also display Live current metering data, or data from the past day, week, month or year.
5.3.3.4. Power Metering Log Display OptionsWhen the Power Metering Log (or Power History) is displayed, the NBB can display Power Metering data for a user specified date range, for either the entire unit or a single line. In addition, the Web Browser Interface also allows you to display Live power metering data, or data from the past day, week, month or year.
5.3.4. Callback Security
The Callback function provides an additional layer of security when callers attempt to
access command mode via modem. When this function is properly configured, modem
users will not be granted immediate access to command mode upon entering a valid
password; instead, the unit will disconnect, and dial a user-defined number before
allowing access via that number. If desired, users may also be required to re-enter the
password after the NBB dials back.
In order for Callback Security to function properly, you must first enable and configure the feature via the System Parameters menu as described in this section, and then define a callback number for each desired user account as described in Section 5.5.
To access the Callback Security menu via the Text Interface, type /F and press [Enter]
and then select the Callback Security option. To access the Callback Security menu via the Web Browser Interface, place the cursor over the General Parameters link, wait for the flyout menu to appear, and then Click on the "Callback Security" link. In both the Text Interface and Web Browser Interface, the Callback Security Menu offers the following options: • Callback Enable: This prompt offers five different configuration options for the
Callback Security feature: (Default = On - Callback (Without Password Prompt.) Off: All Callback Security is disabled.
On - Callback (Without Password Prompt): Callbacks will be performed for
user accounts that include a Callback Number, and the login prompt will not be displayed when the user's modem answers. If the account does not include a Callback Number, that user will be granted immediate access.
On - Callback (With Password Prompt): Callbacks will be performed for user
accounts that include a Callback Number, and the login prompt will be displayed when the user's modem answers (accounts that include a Callback Number will be required to re-enter their username/password when their modem answers.) If the account does not include a Callback Number, then that user will be granted immediate access.
On - Callback ONLY (Without Password Prompt): Callbacks will be performed
for user accounts that include a Callback Number, and the username/password prompt will not be displayed when the user's modem answers. Accounts that do not include a Callback Number will not be able to access command mode via modem.
On - Callback ONLY (With Password Prompt): Callbacks will be performed for
accounts that include a Callback Number, and the username/password prompt will be displayed when the user's modem answers (users will be required to re-enter their username/password when their modem answers.) Accounts that do not include a Callback Number will not be able to access command mode via modem.
• Callback Attempts: The number of times that the NBB will attempt to contact the
Callback number. (Default = 3 attempts.) • Callback Delay: The amount of time that the NBB will wait between Callback
attempts. (Default = 30 seconds.) • After configuring and enabling Callback Security, you must then define a callback phone number for each desired user account (as described in Section 5.5) in order for this feature to function properly. • When using the "On - Callback (With Password Prompt)" option, it is important to remember that accounts that do not include a callback number will be allowed to access command mode without callback verification. 5.3.5. Power Source Configuration
The Power Configuration menu allows you to adjust power measurements in order
to obtain a more accurate determination of how much "real power" is being used by
devices connected to the NBB. Real Power is determined by the following equation:
(Voltage * Amps) * Power Factor To define Power Configuration parameters, access the command mode using an account that permits access to Administrator level commands and then activate the System Parameters Menu.
• In the Text Interface, power source configuration parameters are defined via the Power Configuration menu. • In the Web Browser Interface, power source configuration parameters are selected via the System Parameters menu. The following Power Source Configuration parameters are available: • Voltage Calibration: This option is used to calibrate the voltage readout on the
NBB front panel. To calibrate the voltage, first determine the approximate voltage and then select the Voltage Calibration option and key in the correct voltage. In the Web Browser Interface, the voltage is entered at the System Parameters menu in the Voltage Calibration field. In the Text Interface, the voltage is entered in a submenu of the System Parameters menu. (Default = undefined.) • Power Factor: Can be any value from 0.1 to 1.00. (Default = 1.00.)
• Power Efficiency: Can be any whole number from 1% to 100%. (Default = 100%.)
5.3.6. Scripting Options
The Scripting Options submenu provides access to parameters that are used to set up
the NBB unit for running various scripts.
• To access Scripting Options parameters via the Text Interface, first type /F
and press [Enter] to display the System Parameters Menu, then key in the
number for the Scripting Options item and press [Enter].
• To access the Scripting Options parameters via the Web Browser Interface, place the cursor over the "General Parameters" link, wait for the flyout menu to appear, then click on the "Scripting Options" link. The Scripting Options menu allows the following parameters to be defined: • Command Confirmation: Enables/Disables the Command Confirmation feature.
When enabled, a "Sure" prompt will be displayed before power switching and reboot commands are executed. When disabled, commands will be executed without further prompting. (Default = On.) • Automated Mode: When enabled, the NBB will execute switching and reboot
commands without displaying a confirmation prompt, status screen or confirmation
messages. For more information, please refer to Section 5.3.6.1 or Section 9.3.
(Default = Off.)
Note: When the Automated Mode is enabled, security functions are
suppressed, and users are able to access configuration menus and
control plugs without entering a password. If security is a concern and the
Automated Mode is required, it is recommended to use the IP Security feature
(Section 5.9.3) to restrict access.
• Command Prompt: Allows the Text Interface command prompt to be set to either
MPC, IPS, NPS, NBB, VMR, CCM, RPC or the currently defined Site ID message. (Default = NBB.) • IPS Mode: This parameter sets up the NBB for use with command scripts that
were written for WTI's IPS Series Remote Reboot Switches. When the IPS Mode is enabled, the "IPS" command prompt will be displayed in the Text Mode, User Accounts will not allow definition of a Username, and only the "password" prompt will be displayed when logging into the unit (IPS Mode units will not display a "username" prompt.) (Default = Off.) • The "IPS" command prompt will be displayed in the Text Mode.
• Providing that no Administrator level user accounts are defined, the NBB will not display the username or password prompts upon login to command mode.
• If one or more Administrator level user accounts have been defined, then the NBB will only display the password prompt upon login to command mode. If all Administrator level user accounts (aside from the default "super" account) are deleted, then the NBB will return to the status where no username or password prompts are displayed upon login to command mode.
5.3.6.1. Automated ModeThe Automated Mode allows the NBB to execute switching and reboot commands, without displaying menus or generating response messages. Automated Mode is designed to allow the NBB to be controlled by a device which can generate commands to control power switching functions without human intervention.
When Automated Mode is enabled, power switching and reboot commands are executed without a confirmation prompt and without command response messages; the only reply to these commands is the command prompt, which is re-displayed when each command is completed.
Although Automated Mode can be enabled using either the Web Browser Interface or Text Interface, Automated Mode is designed primarily for users who wish to send ASCII commands to the NBB without operator intervention, and therefore does not specifically apply to the Web Browser Interface. When Automated Mode is enabled, the Web Browser Interface can still be used to invoke switching and reboot commands.
• When the Automated Mode is enabled, password prompts will not be displayed at login, and you will be able to access Administrator Level command functions (including the configuration menus) and control plugs without entering a password. • If you need to enable the Automated Mode, but want to restrict network access to configuration menus, it is strongly recommended to enable and configure the IP Security Function as described in Section 5.9.3. To enable/disable the Automated Mode, go to the System Parameters menu (see Section 5.3,) and then set the "Automated Mode" option to "On". When Automated Mode is enabled, NBB functions will change as follows: 1. All Password Security Suppressed: When a user attempts to access command
mode, the password prompt will not be displayed at either the Setup Port or Network Port. Unless specifically restricted by the IP Security Function, all users will be allowed to access both switching and configuration functions, and all commands will be immediately accepted without the requirement to enter a password.
2. Status Screen Suppressed: The plug status screen will not be automatically
displayed after commands are successfully executed. Note however, that the /S command can still be invoked to display the status screen as needed.
3. "Sure?" Prompt Suppressed: All commands are executed without prompting for
user confirmation.
4. Error Messages Suppressed: Most error messages will be suppressed. Note
however, that an error message will still be generated if commands are invoked using invalid formats or arguments.
All other status display and configuration commands will still function as normal.
5.4. User Accounts
Each time you attempt to access command mode, you will be prompted to enter a username and password. The username/password entered at login determine which outlet(s) you will be allowed to control and what type of commands you will be allowed to invoke. Each username/password combination is defined within a "user account." The NBB allows up to 128 user accounts; each account includes a username, password, security level, plug access rights, service access rights and an optional callback number.
5.4.1. Command Access Levels
In order to restrict access to important command functions, the NBB allows you to set
the command access level for each user account. The NBB offers four access levels:
Administrator, SuperUser, User and View Only. Command privileges for each account
are set using the Add User or Modify User menus.
Each access level grants permission to use a different selection of commands; lower access levels are restricted from invoking configuration commands, while Administrators are granted access to all commands. The four different access levels are listed below: • Administrator: Administrators are allowed to invoke all configuration and power
switching commands, can view all status screens, and can always direct switching commands to all NBB switched outlets.
• SuperUser: SuperUsers are allowed to invoke all power switching commands and
view all status screens. SuperUsers can view configuration menus, but are not allowed to change configuration parameters. SuperUsers are granted access to all NBB outlets.
• User: Users are allowed to invoke power switching commands and view all status
screens, but can only apply commands to outlets that they are specifically granted access to. In addition, Users are not allowed to view configuration menus or change configuration parameters.
• ViewOnly: Accounts with ViewOnly access, are allowed to view Status Menus,
but are not allowed to invoke switching commands, and cannot view configuration menus or change parameters. ViewOnly accounts can display the Plug Status screen, but can only view the status of plugs that are allowed by the account.
Section 17.2 summarizes command availability for all four access levels.
In the default state, the NBB includes one predefined account that provides access to
Administrator commands and allows control of all NBB switched power outlets. The
default username for this account is "super" (lowercase, no quotation marks), and the
password for the account is also "super".
• In order to ensure security, it is recommended that when initially setting up the unit, a new user account with Administrator access should be created, and the "super" account should then be deleted. • If the NBB is reset to default parameters, all user accounts will be cleared, and the default "super" account will be restored. 5.4.2. Plug Access
Each account can be granted access to a different selection of power outlets (plugs)
and plug groups. When accounts are created, the Plug Access parameter and the Plug
Group Access parameter in the Add User menu or Modify User menu are used to grant
or deny access to each plug or plug group. In addition, each access level also restricts
the plugs and plug groups that the account will be allowed to access:
• Administrator: Administrator level accounts are always allowed to control all plugs
and plug groups. Plug access cannot be disabled for Administrator level accounts.
• SuperUser: SuperUser accounts allow access to all plugs and plug groups. Plug
access cannot be disabled for SuperUser accounts.
• User: User level accounts are only allowed to issue switching commands to the
plugs and plug groups that have been specifically permitted via the "Plug Access" parameter in the Add User and Modify User menus.
• ViewOnly: ViewOnly level accounts are not allowed to issue switching commands.
ViewOnly accounts can display the On/Off state of plugs and plug groups, but are limited to the plugs and plug groups specified by the account.
5.4.3. Port Access
The Port Access parameter is used to grant or deny access to the NBB RJ45 Setup Port.
Normally, the Setup port is used for connection to a local control device or an external
modem. The command access level will also determine port access rights for each
account as summarized below:
• Administrator and SuperUser: Accounts with Administrator or SuperUser level
command access are always allowed to connect to the Setup Port. Port access cannot be disabled for Administrator and SuperUser level accounts.
• User: User level accounts are only allowed to connect to the Setup Port when port
access has been specifically enabled for the account. • ViewOnly: Accounts with ViewOnly access are not allowed to create connections
to the Setup Port. 5.5. Managing User Accounts
The User Directory function is employed to create new accounts, display parameters for existing accounts, modify accounts and delete accounts. Up to 128 different user accounts can be created. The "User Directory" function is only available when you have logged into command mode using an account that permits Administrator commands. In both the Text Interface and the Web Browser Interface, the User Directory menu offers the following functions: • View User Directory: Displays currently defined parameters for any NBB user
account as described in Section 5.5.1.
• Add Username: Creates new user accounts, and allows you to assign a username,
password, command level, plug access plug group access, service access and callback number, as described in Section 5.5.2.
• Modify User Directory: This option is used to edit or change account information,
as described in Section 5.5.3.
• Delete User: Clears user accounts, as described in Section 5.5.4.
Note: After you have finished selecting or editing user account parameters,
make certain to save the new account information before proceeding. In the
Web Browser Interface, click on the "Add User" button to save parameters; in
the Text Interface, press the [Esc] key several times until the NBB displays the
"Saving Configuration" message and the cursor returns to the command prompt.
5.5.1. Viewing User Accounts
The "View User Directory" option allows you to view details about each account. The
View User option will not display actual passwords, and instead, the password field
will read "defined". The View User Accounts function is only available when you
have accessed command mode using a password that permits Administrator Level
commands.
5.5.2. Adding User Accounts
The "Add Username" option allows you to create new accounts. Note that the Add User
function is only available when you have accessed command mode using a password
that permits Administrator Level commands. The Add User Menu can define the
following parameters for each new account:
• Username: Up to 32 characters long, and cannot include non-printable characters.
Duplicate usernames are not allowed. (Default = undefined.) • Password: Five to sixteen characters long, and cannot include non-printable
characters. Note that passwords are case sensitive. (Default = undefined.) • Access Level: Determines which commands this account will be allowed to
access. This option can set the access level for this account to "Administrator", "SuperUser", "User" or "ViewOnly." For more information on Command Access Levels, please refer to Section 5.4.1 and Section 17.2. (Default = User.) • Port Access: Determines whether or not the account will be allowed to connect to
the serial Setup Port. (Defaults; Administrator and SuperUser = Always Enabled, User = Disabled.) Note: ViewOnly level accounts cannot be granted access to the Setup Port.
• Plug Access: Determines which outlet(s) this account will be allowed to control.
(Defaults; Administrator and SuperUser = All Plugs On, User = All Plugs Off, ViewOnly = All Plugs Off.) • Administrator and SuperUser level accounts always have access to all plugs.
• User level accounts will only have access to the plugs that are defined via the "Plug Access" parameter. • ViewOnly accounts are allowed to display the Plug Status Screen, but are limited to the plugs specified by the account. ViewOnly accounts are not allowed to invoke switching and reboot commands. • Plug Group Access: Determines which plug groups this account will be allowed to
control. For more information on Plug Groups, please refer to Section 5.6. (Defaults; Administrator and SuperUser = All Plug Groups On, User = All Plug Groups Off, ViewOnly = All Plug Groups Off.) • In order to use this feature, Plug Groups must first be defined as described in Section 5.6. • Administrator and SuperUser level accounts will always have access to all plug groups. • User Level accounts will only have access to the plug groups that are defined via the Plug Group Access parameter. • ViewOnly accounts are allowed to display the On/Off status of plug groups via the Plug Status Screen, but are limited to the plug groups specified by the account. ViewOnly accounts are not allowed to invoke switching and reboot commands. • Service Access: Determines whether this account will be able to access command
mode via Serial Port, Telnet/SSH or Web. For example, if Telnet/SSH Access is disabled for this account, then this account will not be able to access command mode via Telnet or SSH. (Default = Serial Port = On, Telnet/SSH = On, Web = On.) • Current/Power Metering: Enables/Disables current and power metering for this
account. When disabled, this account will not be able to view current or power readings or display current or power history. Note that in order for accounts to be able to display these logs, Current and Power Metering must be enabled via the Systems Parameters menu as described in Section 5.3. (Default = Off.) • Callback Phone Number: Assigns a number that will be called when this account
attempts to access command mode via modem, and the Callback Security Function has been enabled as described in Section 5.3.4. (Default = undefined.) • If the Callback Number is not defined, then Callbacks will not be performed for this user. • If the Callback Number is not defined for a given user, and the Callback Security feature is configured to use either of the "On - Callback" options, then this user will be granted immediate access to command mode via modem. • If the Callback Number is not defined for a given user, and the Callback Security feature is configured to use the "On - Callback ONLY" option, then this user will not be able to access command mode via Modem. • When using the "On - Callback (With Password Prompt)" option, it is important to remember that accounts that do not include a callback number will be allowed to access command mode without callback verification. Note: After you have finished selecting or editing account parameters, make
certain to save the new account information before proceeding. In the Web
Browser Interface, click on the "Add User" button to save parameters; in the Text
Interface, press the [Esc] key several times until the NBB displays the "Saving
Configuration" message and the cursor returns to the command prompt.
5.5.3. Modifying User Accounts
The "Edit User Directory" function allows you to edit existing accounts in order to
change parameters, plug access rights or Administrator Command capability. Note
that the Edit/Modify User function is only available when you have accessed command
mode using a password that permits Administrator Level commands. Once you have
accessed the Modify Users menu, use the menu options to redefine parameters in the
same manner employed for the Add User menu, as discussed in Section 5.5.2.
Note: After you have finished changing parameters, make certain to save the
changes before proceeding. In the Web Browser Interface, click on the "Modify
User" button to save parameters; in the Text Interface, press the [Esc] key
several times until the NBB displays the "Saving Configuration" message.
5.5.4. Deleting User Accounts
This function is used to delete individual user accounts. Note that the Delete User
function is only available when you have accessed command mode using a password
that permits Administrator Level commands.
• Deleted accounts cannot be automatically restored.
• The NBB allows you to delete the default "super" account, which is included to permit initial access to command mode. Before deleting the "super" account, make certain to create another account that permits Administrator Access. If you do not retain at least one account with Administrator Access, you will not be able to invoke Administrator level commands. 5.6. The Plug Group Directory
The Plug Group Directory allows you to designate "groups" of plugs that are dedicated to a similar function, and will most likely be switched or rebooted all at the same time or controlled by the same type of user account.
For example, an individual equipment rack might include an assortment of devices that belong to different departments or clients. In order to simplify the process of granting plug access rights to the accounts that will control power to these devices, you could assign all of the plugs for the devices belonging to Department A to a Plug Group named "Dept_A", and all of the plugs for devices belonging to Department B to a Plug Group named "Dept_B". When user accounts are defined later, this would allow you to quickly grant access rights for all of the plugs for the devices belonging to Department A to the appropriate user accounts, by merely granting access to the Dept_A Plug Group, rather than by selecting the specific, individual plugs for each user account.
Likewise, Plug Groups allow you to direct On/Off/Boot commands to a series of plugs, without addressing each plug individually. Given the example above, you could quickly reboot all plugs for Department A, by either including the "Dept_A" Plug Group name in a /BOOT command line via the Text Interface, or by using the Plug Group Control menu in the Web Browser Interface.
The Plug Group Directory function is only available when you have logged into command mode using an account that permits Administrator commands. In both the Text Interface and the Web Browser Interface, the Plug Group Directory menu offers the following functions: • View Plug Group Directory: Displays currently defined plug access rights for any
NBB Plug Group as described in Section 5.6.1.
• Add Plug Group to Directory: Creates new Plug Groups, and allows you to assign
plug access rights to each group as described in Section 5.6.2.
• Modify Plug Group Directory: This option is used to edit or change plug access
rights for each Plug Group, as described in Section 5.6.3.
• Delete Plug Group from Directory: Clears Plug Groups that are no longer
needed, as described in Section 5.6.4.
5.6.1. Viewing Plug Groups
The "View Plug Group Directory" option allows you to view the configuration of each
Plug Group. Note that the View Plug Group Directory function is only available when
you have accessed command mode using a password that permits Administrator Level
commands. In the Web Browser Interface, the Plug Group Directory can be viewed
by clicking on the link on the left hand side of the page. In the Text Interface, the Plug
Group Directory can be viewed by typing /G and pressing [Enter] and then selecting
the option from the resulting submenu.
5.6.2. Adding Plug Groups
The "Add Plug Group to Directory" option allows you to create new Plug Groups and
assign plug access rights to each group. The Add Plug Group function is only available
when you have accessed command mode using a password that permits Administrator
Level commands. The Add Plug Group Menu can be used to define the following
parameters for each new account:
• Plug Group Name: Assigns a name to the Plug Group. (Default = undefined.)
• Plug Access: Determines which plugs this Plug Group will be allowed to control.
(Default = undefined.) • In the Text Interface, Plug Access is configured by selecting item 2 and then selecting the desired plugs from the resulting submenu. • In the Web Browser Interface, Plug Access is configured by selecting the desired plugs from a list of all plugs in the Add Plug Group menu. • After you have finished defining or editing Plug Group parameters, make certain to save the changes before proceeding. In the Web Browser
Interface, click on the "Add Plug Group" button to save parameters; in the
Text Interface, press the [Esc] key several times until the NBB displays the
"Saving Configuration" message and the cursor returns to the command
prompt.
5.6.3. Modifying Plug Groups
The "Modify Plug Group" function allows you to edit existing Plug Groups in order
to change plug access rights. Note that this function is only available when you
have accessed command mode using a password that permits Administrator Level
commands. Once you have accessed the Modify Plug Group menu, use the menu
options to redefine parameters in the same manner that is used for the Add Plug Group
menu, as discussed in Section 5.6.2.
Note: After you have finished changing or editing parameters, make certain to
save the changes before proceeding. In the Web Browser Interface, click on
the "Modify Plug Groups" button to save parameters; in the Text Interface, press
the [Esc] key several times until the NBB displays the "Saving Configuration"
message and the cursor returns to the command prompt.
5.6.4. Deleting Plug Groups
This function is used to delete individual Plug Groups. Note that this function is only
available when you have accessed command mode using a password that permits
Administrator Level commands.
Note: Deleted Plug Groups cannot be automatically restored.
5.7. Defining Plug Parameters
The Plug Parameters Menu is used to define Plug Names, boot/sequence delay times and Power Up Default values for each NBB Switched AC Outlets. Note that this function is only available when you have accessed command mode using a password that permits Administrator Level commands. The Plug Parameters Menu allows you to define the following parameters: • Plug Name: (Up to 16 Characters, Default = undefined.)
Note: Plug Names must begin with either a lower case alphabetic letter
or upper case alphabetic letter. Plug Names cannot begin with a number
character or symbol character.
• Boot/Seq. Delay: When more than one plug is switched On or a reboot cycle is
initiated, the Boot/Sequence delay determines how much time will elapse before the next plug is switched On. When the Boot/Sequence Delay is applied, the NBB will wait for the user-defined delay period before switching On the next plug. When Reboot cycles and switching actions are initiated, the Boot/Sequence Delay will be applied as follows: (Default = 0.5 Second.) Reboot Cycle Delay: During a reboot cycle, the NBB will first switch all selected
plugs "Off" (with a 0.5 second pause between each "Off" operation), and then begin to switch selected plugs back On again, pausing for the user-defined Boot/Sequence Delay before switching On the next plug. For example, if the Boot/Sequence Delay for Plug 3 is ten seconds, then the NBB will pause for ten seconds before proceeding to the next plug.
"On" Sequence Delay: When two or more plugs are switched On, the NBB will
pause for the user-defined Boot/Sequence Delay before switching the next plug.
• Power Up Default: Determines how this plug will react when the Default
command (/DPL) is invoked, or after power to the unit has been interrupted and then restored. After the default command is invoked, or power is restored, the NBB will automatically switch each plug On or Off as specified by the Power-Up Default. (Default = On).
• If you have accessed command mode using an account that permits Administrator or SuperUser level commands, then the Default command will be applied to all switched plugs. • If you have accessed command mode via an User Level account, then the Default command will only be applied to plugs allowed by your account. • Boot Priority: The Boot Priority parameter determines the order in which plugs will
be switched On. The Plug that has been assigned a Boot Priority of "1" will always be switched on first, followed by the plug that has been assigned the Boot Priority of "2", and so forth. For more information on the Boot Priority parameter, please refer to Section 5.7.1. (Default = All plugs prioritized according to Plug Number.) 5.7.1. The Boot Priority Parameter
Normally, when an "On" or "Reboot" command is invoked, the NBB will switch on its
plugs in their default, numeric order. Although in many cases, the default, numeric order
will work fine, there are other cases where an individual device (such as a router) must
be switched on first, in order to support a second device that will be switched on later.
The Boot Priority Parameter simplifies the process of setting the order in which plugs are switched On, by assigning a priority number to each plug, rather than by requiring the user to make certain that devices are always connected to the NBB in a set order. Likewise, when new devices are added to your equipment rack, the Boot Priority Parameter eliminates the need to unplug all existing devices and then rearrange the plugs connected to the NBB (and re-define plug parameters) to ensure that they are switched on in the desired order.
• No two plugs can be assigned the same Boot Priority number.
• When a higher Boot Priority is assigned to any given plug, all subsequent plugs will have their boot priorities lowered by a factor of 1. • The Boot Priority is also displayed on the Plug Status Screen. 5.7.1.1. Example 1: Change Plug A3 to Priority 1In the Example shown in Figure 5.1, we start out with all Plugs set to their default Boot Priorities, with Plug A1 first, Plug A2 second and so forth. Next, the Boot Priority for Plug A3 is changed to Priority 1. This means that Plug A3 will now be switched On first after a reboot, and that Plug A1 will now be switched On second, Plug A2 will be third, etc.
Note that when the Boot Priority for Plug A3 is set to 1, the Boot Priorities for all plugs that were previously Booted before plug A1 are now lowered by a factor of one.
(Assign Plug A3
(Plug No.) Priority
to Priority 1)
(Plug No.) Priority
Figure 5.1: Boot Priority Example 1
5.7.1.2. Example 2: Change Plug A5 to Priority 2In the second Example shown in Figure 5.2, we start out with Boot Priorities for the plugs set as they were at the end of Example 1; Plug A3 is first, Plug A1 is second, Plug A2 is third, Plug A4 is fourth, and Plug A6 is sixth.
Next, the Boot Priority for Plug A5 is changed to Priority 2. This means that Plug A3 will continue to be switched on first after a reboot, but now Plug A5 will be switched on second, Plug A3 will be third, Plug A2 will be fourth, Plug A4 will be fifth and Plug A6 will still be sixth.
Once again, note that when the Boot Priority for Plug A5 is set to 2, the Boot Priorities for all plugs that were previously Booted before plug A5 are now lowered by a factor of one (Assign Plug A5
(Plug No.) Priority
to Priority 2)
(Plug No.) Priority

5.8. Serial Port Configuration
The serial Port Configuration menus allow you to select parameters for the NBB serial Setup Port. In addition, the Serial Port Configuration menu (Port Parameters) can also be used to set communications parameters, disable Administrator level commands at the serial Setup Port and also select a number of other parameters described below.
• Baud Rate: Any standard rate from 300 bps to 115.2K bps. (Default = 9600 bps)
• Bits/Parity: (Default = 8-None)
• Stop Bits: (Default = 1)
• Handshake Mode: XON/XOFF, RTS/CTS (hardware), Both, or None.
(Default = RTS/CTS) • Administrator Mode: Permits/denies port access to Administrator and
SuperUser level accounts. When enabled (Permit), the port will be allowed to invoke Administrator and SuperUser level commands, providing they are issued by an account that permits them. If disabled (Deny), then accounts that permit Administrator and SuperUser level commands will not be allowed to access command mode via this port. (Default = Permit.) • Logoff Character: The Logoff Character determines the command(s) or
character(s) that must be issued at this port in order to disconnect this port from
another port. Note that the Logoff Character does not apply to Direct Connections.
(Default = X.)
• Sequence Disconnect: Enables/Disables and configures the disconnect
command. This item offers the option to disable the Sequence Disconnect, select a one character format or a three character format. (Default = One Character.) • Inactivity Timeout: Enables and selects the Timeout Period for this port. If
enabled, the Setup Port will disconnect when no additional data activity is detected for the duration of the timeout period. (Default = 5 Minutes.) • Command Echo: Enables or Disables command echo at the Setup Port. When
disabled, commands that are sent to the Setup Port will still be invoked, but the actual keystrokes will not be displayed on your monitor. (Default = On.) • Accept Break: Determines whether the port will accept breaks received from the
attached device. When enabled, breaks received at the port will be passed to any port that this port is connected to. When disabled, breaks will be refused at this port. (Default = On.) Port Mode Parameters:
• Port Name: Allows you to assign a name to the Setup Port. (Default = Undefined.)
• Port Mode: Selects the port mode for the Serial port. The port mode can be set to
Normal Mode, Modem Mode or Modem PPP Mode. (Default = Normal Mode) Depending on the Port Mode selected, the NBB will display additional prompts listed below. In the Text Interface, these parameters are accessible via a submenu, which will only be active when the appropriate port mode is selected. In the Web Browser Interface, fields will be "grayed out" unless the corresponding port mode is selected.
Normal Mode: Allows communication with a local computer and permits access
to command mode. When the Normal Mode is selected, the following mode-specific parameter can also be defined: DTR Output: Determines how DTR will react when the port disconnects. DTR
can be held low, held high, or pulsed for 0.5 seconds and then held high. (Default = Pulse.) Modem Mode: Permits access to command mode and simplifies connection
to an external modem. Modem Mode ports can perform all functions normally available in Normal Mode, but Modem Mode also allows definition of the following, additional parameters: Reset String: Redefines the modem reset string. The Reset String can be
sent prior to the Initialization string. (Default = ATZ.)
Initialization String: Defines a command string that can be sent to initialize a
modem to settings required by your application.
(Default = ATE1M1&C1&D2S0=1&B1&H1&R2)
Hang-Up String: Although the NBB will pulse the DTR line to hang-up an
attached modem, the Hang-Up string is often useful for controlling modems that do not use the DTR line. (Default = undefined.) Periodic Reset Value: Determines how often the Reset String will be sent to
the modem at this port.
No Dialtone Enable: When this item is "On" the No Dialtone Alarm can be
enabled as described in Section 7.8. When the No Dialtone Alarm is enabled and properly configured, the NBB can provide notification if the unit detects that a phone line connected to a modem installed at this port is dead. (Default = Off.) Note: When communicating with the NBB via modem, these parameters will
not be changed until after you exit command mode and disconnect.
Modem PPP Mode: Allows data that is normally sent via ethernet to be sent via
phone line. When Modem PPP Mode is selected, the following modem-related parameters will be available: Reset String: Redefines the modem reset string. The Reset String can be
sent prior to the Initialization string. (Default = ATZ.)
Initialization String: Defines a command string that is used to initialize the
modem to settings required for PPP communication
(Default = ATQ0V1E1S0=0&C1&D2)
Hang-Up String: Although the NBB will pulse the DTR line to hang-up an
attached modem, the Hang-Up string is often useful for controlling modems that do not use the DTR line. (Default = undefined.) Periodic Reset Interval: Determines how often the Reset String will be sent
to the modem at this port. (Default = 15 Minutes.) No Dialtone Enable: When this item is "On" the No Dialtone Alarm can be
enabled as described in Section 7.8. When the No Dialtone Alarm is enabled, the NBB can provide notification if the unit detects that a phone line connected to a modem installed at this port is dead. (Default = Off.) Periodic Reset Location: The IP address or URL for the website that will
be used to keep the PPP connection alive when not in use. The NBB will regularly ping the selected IP address or URL in order to keep the connection alive. (Default = undefined) • In order to select a domain name as the Periodic Reset Location, you must first define the Domain Name Servers as described in Section 5.9.5. • The IP Address, P-t-P and Subnet Mask parameters cannot be defined by the user and will be automatically supplied by the ISP when a PPP communication is started. PPP Phone Number: The phone number for the line that will be used for PPP
communication. (Default = undefined) User Name: The user name for the ISP account that will be used for PPP
communication. (Default = undefined) Password: The password for the ISP count that will be used for PPP
communication (Default = undefined) IP Address: The temporary IP address that will be assigned to the PPP
communication session by the ISP. Note that this item cannot be defined by the user and will be automatically supplied by the ISP when a PPP communication session is started. (Default = undefined) P-t-P: Note that this item cannot be defined by the user and will be
automatically supplied by the ISP when a PPP communication session is started. (Default = undefined) Subnet Mask: Note that this item cannot be defined by the user and will
be automatically supplied by the ISP when a PPP communication session is started. (Default = undefined) 5.9. Network Configuration
The Network Parameters Menus are used to select parameters and options for the Network Port and also allow you to implement IP Security features, which can restrict access based on the user's IP Address.
Although the Web Browser Interface and Text Interface allow definition of essentially the same parameters, parameters are arranged differently in the two interfaces. In the Text Interface, most network parameters are defined via one menu which is accessed using the /N command. In the Web Browser Interface, network parameters are divided into separate menus which are accessed via the Network Configuration flyout menu.
• Settings for network parameters depend on the configuration of your network. Please contact your network administrator for appropriate settings. • The Network Parameters Menu selects parameters for all 16 logical Network • The IP Address, Subnet Address and Gateway Address cannot be changed via the Web Browser Interface. In order to change these parameters, you must access the unit via the Text Interface. • When a new IP Address is selected, or the status of the DHCP feature is changed, the unit will disconnect and reconfigure itself with the new values when you exit the Network Parameters Menu. When configuring the unit, make certain your DHCP server is set up to assign a known, fixed IP address in order to simplify reconnection to the unit after the new address has been assigned. DHCP Parameters cannot be changed via the Web Browser Interface. • The Network Parameters menu is only available when you have logged into command mode using an account and port that permit Administrator level commands (Supervisor Mode enabled.) The Network Parameters menu allows you to define the parameters discussed in the following sections. Note that although the descriptions of network parameters are arranged according to the Web Browser Interface, in the Text Interface, most parameters are found in two large menus: one for IPv4 and one for IPv6. Note that both the IPv4 configuration menu and the IPv6 configuration menu offer essentially the same parameters. To access the network configuration menus, proceed as follows: • Text Interface: To define network parameters for the IPv4 protocol, type /N and
press [Enter]. To define network parameters for the IPv6 protocol, type /N6 and
• Web Browser Interface: Place the cursor over the "Network Configuration" link
on the left hand side of the screen. When the fly-out menu appears, click on the appropriate link to display the desired menu. Note that some submenus offer the option to define IPv4 or IPv6 parameters and that IPv4 and IPv6 menus include a link that can be used to jump to the other protocol.
5.9.1. Network Port Parameters
In the Text Interface, these parameters are found in the main Network Configuration
menu. In the Web Browser Interface, these parameters are found by placing the cursor
over the "Network Configuration" link on the left hand side of the screen, and then
clicking on the "Network Port Parameters" link in the resulting fly-out menu.
• Administrator Mode: Permits/denies port access by accounts that allow
Administrator or SuperUser level commands. When enabled (Permit), the port will be allowed to invoke Administrator and SuperUser level commands, providing they are issued by an account that permits them. If disabled (Deny), then accounts that permit Administrator and SuperUser level commands will not be allowed to access command mode via this port. (Default = Permit.) • Logoff Character: Defines the Logoff Character for this port. This determines
which command(s) must be issued at this port in order to disconnect from a second
port. (Default = X ([Ctrl] plus [X]).)
Note: The Sequence Disconnect parameter can be used to pick a one
character or a three character logoff sequence.
• Sequence Disconnect: Enables/Disables and configures the Resident Disconnect
command. Offers the option to either disable the Sequence Disconnect, or select a one character, or three character command format. (Default = One Character.) • The One Character Disconnect is intended for situations where the destination port should not receive the disconnect command. When the
Three Character format is selected, the disconnect sequence will pass
through to the destination port prior to breaking the connection.
• When Three Character format is selected, the Resident Disconnect uses the format "[Enter]LLL[Enter]", where L is the selected Logoff Character.
• Inactivity Timeout: Enables and selects the Inactivity Timeout period for the
Network Port. If enabled, and the port does not receive or transmit data for the specified time period, the port will disconnect. (Default = 5 Minutes.) • Command Echo: Enables or Disables the command echo for the Network Port.
• Accept Break: Determines whether the port will accept breaks received from the
attached device, and pass them along to a connected port. When enabled, breaks received at this port will be passed to any port this port is connected to, and sent to the device connected to the other port. When disabled, breaks will be refused at this port. (Default = On.) • Multiple Logins: (Text Interface Only) If the NBB is installed in an environment
that does not include communication via an open network (local communication only), then the Multiple Logins parameter can be used to determine whether or not multiple users will be able to communicate with the unit at the same time. If this parameter is set to "Off" then only one user will be allowed to communicate with the unit at a time. (Default = On.) 5.9.2. Network Parameters
In the Text Interface, these parameters are accessed via the main Network Configuration
menu, which can be activated by typing /N (for IPv4 parameters) or /N6 (for IPv6
parameters) and then pressing [Enter]. In the Web Browser Interface, these parameters
are found by placing the cursor over the "Network Configuration" link on the left hand
side of the screen, and then clicking on the "Network Parameters" link in the resulting
fly-out menu.
Note: The IP Address, Subnet Mask, Gateway Address and DHCP status
cannot be changed via the Web Browser Interface. In order to change these
parameters, you must access the NBB via the Text Interface.
• IP Address: (Default = 192.168.168.168.)
• Subnet Mask: (Default = 255.255.255.0.)
• Gateway Address: (Default = undefined.)
• DHCP: Enables/Disables Dynamic Host Configuration Protocol. When this option
is "On", the NBB will perform a DHCP request. Note that in the Text Interface, the MAC address for the NBB is listed on the Network Status Screen. (Default = Off.) Note: Before configuring this feature, make certain your DHCP server is set up
to assign a known, fixed IP address. You will need this new IP address in order
to reestablish a network connection with the NBB unit.
• Telnet Access: Enables/disables Telnet access. When Telnet Access is "Off," users
will not be allowed to establish a Telnet connection to the unit. Note that in the Text Interface, this item also provides access to the "Telnet Port" and "Maximum per Source" parameters. (Default = On.) • Telnet Port: Selects the TCP/IP port number that will be used for Telnet
connections. In the Text Interface, this item is defined via a submenu, displayed when the Telnet Access parameter is selected. (Default = 23.) • Max. Per Source: The maximum number of Telnet sessions that will be allowed
per user MAC address. (Default = 4.) • In the Text Interface, the "Per Source" parameter is defined via a submenu of item 21 (Telnet Access) in the Network Parameters menu. • After changing the "Max Per Source" parameter, you must log out of all pre- existing Telnet sessions in order for the new maximum value to be applied. • SSH Access: Enables/disables SSH communication. (Default = On.)
• SSH Port: Selects the TCP/IP port number that will be used for SSH connections.
Note that in the Text Interface, this option is defined via a submenu that is displayed when the SSH Access parameter is selected (item number 22). (Default = 22.) • HTTP Access (Web Access): Enables/disables the Web Browser Interface.
When disabled, users will not be allowed to contact the unit via the Web Browser Interface. (Default = Off.) • HTTP Port: Selects the TCP/IP port number that will be used for Web Access.
• HTTPS Access: Enables/disables HTTPS communication. For instructions on
setting up SSL encryption, please refer to Section 14. (Default = On.) • HTTPS Port: Selects the TCP/IP port number that will be used for HTTPS
connections. (Default = 443.) • In the Text Interface, HTTP and HTTPS parameters reside in a separate submenu. To enable and configure HTTP and HTTPS Access via the
Text Interface, access the Network Configuration Menu as described in
Section 5.9, then type 23, press [Enter] and use the resulting submenu to
• When the Web Access parameter is defined via the Text Interface, the resulting submenu will also allow you to select SSL (encryption) parameters as described in Section 14. • Harden Web Security: When the Harden Web Security feature is On (default,) only
the high and medium cypher suites for SSLv3 and TLSv1 will be enabled. When the Harden Web Security feature is Off, all SSL protocols will be enabled, allowing compatibility with older browsers. Note that in the Text Interface, the Harden Web Security option is found in the Web Access submenu. (Default = On.) • SYSLOG Addresses: Defines the IP addresses for the Syslog Daemon(s) that
will receive log records generated by the NBB. Allows definition of IP addresses for both a primary Syslog Daemon and an optional secondary Syslog Daemon. SYSLOG Addresses can be entered in either IPv4 or IPv6 format, or in domain name format (up to 64 characters.) For more information, please refer to Section 11. (Default = undefined.) • The Syslog Address submenu in the Text Interface and the Network Parameters submenu in the Web Browser Interface both include a Ping Test function that can be used to ping the user-selected Syslog IP Addresses in order to verify that valid IP addresses have been entered. In order for the Ping Test feature to function, your network and/or firewall must be configured to allow ping commands. • In addition to the Ping Test feature, the /TEST command in the Text Interface or the "Test" option in the Web Browser Interface can also be used to ping the currently defined Syslog Addresses in order to make certain that the IP addresses are responding. • Ping Access: Enables/Disables response to the ping command. When Disabled,
the NBB will not respond to Ping commands. Note that disabling Ping Access at the Network Port will not effect the Ping-No-Access Alarm. (Default = On.) • Raw Socket Access: Enables/disables Raw Socket Protocol access to the
Network Port via Direct Connect and selects the port number for Raw Socket Access. This item can be used to enable or disable Raw Socket Protocol access and select either port 23 or port 3001 for use for Raw Socket connections. (Default = Off.) • The Raw Socket Access option is often useful for users who encounter network problems when attempting to communicate with the NBB using a script that was previously written for our legacy IPS product line. • If the "On (23)" option is selected, you must either disable Telnet Port 23 or use the Telnet Access option to select a port other than Port 23. • When the Raw Socket Access option is enabled, you must connect to the NBB using the port number selected for Raw Socket Access. For example,
if the NBB IP address is "1.2.3.4", and port 3001 has been selected for Raw
Socket Acess, in order to establish a Raw Socket connection to the NBB's
Network Port, then on a UNIX system, the connection command would be: $
telnet 1.2.3.4 3001 [Enter].
5.9.3. IP Security
The IP Security feature allows the NBB to restrict unauthorized IP addresses from
establishing inbound connections to the unit via telnet or Web Browser. This allows
you to grant access to only a specific group of Telnet or Web IP addresses, or block
a particular IP address completely. In the default state, the NBB accepts incoming IP
connections from all hosts.
In the Text Interface, IP Security parameters are defined via the Network Configuration menu. In the Web Browser Interface, these parameters are found by placing the cursor over the "Network Configuration" link, and then clicking on the "IP Security" link in the resulting fly-out menu. In the default state, IP Security is disabled. The IP Security Function employs a TCP Wrapper program which allows the use of standard, Linux operators, wild cards and net/mask pairs to create a host based access control list.
The IP Security configuration menus include "hosts.allow" and "hosts.deny" client lists. When setting up IP Security, you must enter IP addresses for hosts that you wish to allow in the Allow list, and addresses for hosts that you wish to deny in the Deny list. Since Linux operators, wild cards and net/mask pairs are allowed, these lists can indicate specific addresses, or a range of addresses to be allowed or denied. When the IP Security feature is properly enabled, and a client attempts to connect, the NBB will perform the following checks: 1. If the client's IP address is found in the "hosts.allow" list, the client will be granted immediate access. Once an IP address is found in the Allow list, the NBB will not check the Deny list, and will assume you wish to allow that address to connect.
2. If the client's IP address is not found in the Allow list, the NBB will then proceed to check the Deny list.
3. If the client's IP Address is found in the Deny list, the client will not be allowed to 4. If the client's IP Address is not found in the Deny list, the client will be allowed to connect, even if the address was not found in the Allow list.
• If the NBB finds an IP Address in the Allow list, it will not check the Deny list, and will allow the client to connect. • If both the Allow and Deny lists are left blank, then the IP Security feature will be disabled, and all IP Addresses will be allowed to connect (providing that the proper password and/or SSH key is supplied.) • When the Allow and Deny lists are defined, the user is only allowed to specify the Client List; the Daemon List and Shell Command cannot be defined. 5.9.3.1. Adding IP Addresses to the Allow and Deny ListsTo add an IP Address to the Allow or Deny list, and begin configuring the IP Security feature, proceed as follows.
• Both the Allow and Deny list can include Linux operators, wild cards, and net/mask pairs. • In some cases, it is not necessary to enter all four "digits" of the IP Address. For example, if you wish to allow access to all IP addresses that begin with "192," then you would only need to enter "192." • The IP Security Configuration menu is only available when you have accessed command mode using an account that permits Administrator level commands. • In order to use domain names in the Allow List and/or Deny List, you must first define IP address(es) for the desired Domain Name Server(s) as described in Section 5.9.5. 1. Access the IP Security Configuration Menu.
a) Text Interface: Type /N [Enter] to define addresses in IPv4 format, or type
/N6 and press [Enter] to define addresses in IPv6 format. The Network
Configuration Menu will be displayed. From the Network Configuration Menu,
type 5 [Enter] to display the IP Security Menu.
b) Web Browser Interface: Place the cursor over the "Network Configuration"
link on the left hand side of the screen. When the fly-out menu appears, click on the "IP Security" Link to display the IP Security Menu. The IP Security menu in the Web Browser Interface will accept addresses in either IPv4 or IPv6 format.
2. Allow List: Enter the IP Address(es) for the clients that you wish to allow. Note that
if an IP Address is found in the Allow list, the client will be allowed to connect, and the NBB will not check the Deny list.
a) Text Interface: Note the number for the first empty field in the Allow list, then
type that number at the command prompt, press [Enter], and then follow the
instructions in the resulting submenu.
b) Web Browser Interface: Place the cursor in the first empty field in the
parameters menu, then key in the desired IP Address, operators, wild cards, and/or net/mask pairs.
3. Deny List: Enter the IP Address(es) for the clients that you wish to deny. Note that
if the client's IP Address is not found in the Deny List, that client will be allowed to connect. Use the same procedure for entering IP Addresses described in Step 2 above.
5.9.3.2. Linux Operators and Wild CardsIn addition to entering a specific IP address or partial IP address in the Allow or Deny list, you may also use standard Linux operators or wild cards. In most cases, the only operator used is "EXCEPT" and the only wild card used is "ALL," but more experienced Linux users may note that other operators and wild cards may also be used.
EXCEPT: This operator creates an exception in either the "allow" list or "deny" list. For
example, if the Allow list includes a line which reads "192. EXCEPT 192.255.255.6," then
all IP address that begin with "192." will be allowed; except 192.255.255.6 (providing that
this address appears in the Deny list.)
ALL: The ALL wild card indicates that all IP Addresses should be allowed or denied.
When ALL is included in the Allow list, all IP addresses will be allowed to connect;
conversely, if ALL is included in the Deny list, all IP Addresses will be denied (except for
IP addresses listed in the Allow list.) For example, if the Deny list includes a line which
reads "ALL EXCEPT 168.255.192.192," then all IP addresses except 168.255.192.192 will
be denied (except for IP addresses that are listed in the Allow list.)
Net/Mask Pairs: An expression of the form "n.n.n.n/m.m.m.m" is interpreted as a "net/
mask" pair. A host address is matched if "net" is equal to the bitwise AND of the address
and the "mask." For example, the net/mask pattern "131.155.72.0/255.255.254.0"
matches every address in the range "131.155.72.0" through "131.155.73.255."
5.9.3.3. IP Security Examples
1. Mostly Closed: Access is denied by default and the only clients allowed,
are those explicitly listed in the Allow list. To deny access to all clients except 192.255.255.192 and 168.112.112.05, IP Security would be defined as follows: • Allow List: 1. 192.255.255.192 2. 168.112.112.05 • Deny List: 1. ALL 2. Mostly Open: Access is granted by default, and the only clients denied access,
are those explicitly listed in the Deny list. To allow access to all clients except 192.255.255.192 and 168.112.112.05, the IP Security would be defined as follows: • Allow List: 1. ALL EXCEPT 192.255.255.192, 168.112.112.05 • Deny List: 1. 192.255.255.192, 168.112.112.05 • When defining a line in the Allow or Deny list that includes several IP addresses, each individual address is separated by either a space, a comma, or a comma and a space as shown in Example 2 above. • Take care when using the "ALL" wild card. When ALL is included in the Allow list, it should always include an EXCEPT operator in order to allow the unit to proceed to the Deny list and determine any addresses you wish to deny. 5.9.4. Static Route
The Static Route menu allows you to type in Linux routing commands that will be
automatically executed each time that the unit powers up or reboots. In the Text
Interface, the Static Route menu is accessed via the Network Configuration menu. In
the Web Browser Interface, the Static Route menu is accessed via the flyout menus
under the Network Configuration link. Note that parameters defined via this menu will
be applied to both IPv4 and IPv6 communication.
5.9.5. Domain Name Server
The DNS menu is used to select IPv4 or IPv6 format IP addresses for Domain Name
Servers. When web and network addresses are entered, the Domain Name Server
interprets domain names (e.g., www.yourcompanyname123.com), and translates them
into IP addresses. In the Text Interface, the DNS menu is accessed via the Network
Configuration menu. In the Web Browser Interface, the DNS menu is accessed via the
flyout menus under the Network Configuration link. Note that if you don't define at least
one DNS server, then IP addresses must be used, rather than domain names. Note that
parameters defined via this menu will be applied to both IPv4 and IPv6 communication.
The Domain Name Server menu includes a Ping Test feature, that allows you to ping the IP addresses for each user-defined domain name server in order to check that a valid IP address has been entered.
Note: In order for the Ping Test feature to function, your network and/or firewall
must be configured to allow ping commands.
5.9.6. SNMP Access Parameters
These menus are used to select access parameters for the SNMP feature. The SNMP
Access Parameters Menu allows the following parameters to be defined:
Note: After you have configured SNMP Access Parameters, you will then be
able to manage the NBB User Directory, control power and reboot switching
and display unit status via SNMP, as described in Section 13.
• Enable: Enables/disables SNMP Polling. (Default = Off.)
Note: This item only applies to external SNMP polling of the NBB; it does not
effect the ability of the NBB to send SNMP traps.
• Version: Determines which SNMP Version the NBB will respond to. For example,
if this item is set to V3, then clients who attempt to contact the NBB using SNMPv2 will not be allowed to connect. (Default = V1/V2 Only.) • Read Only: Enables/Disables the "Read Only Mode", which controls the ability to
access configuration functions and invoke switching commands. When Enabled ("Yes"), you will not be able to change configuration parameters or invoke other commands when you contact the NBB via SNMP. (Default = No.) Note: In order to define user names for the NBB via your SNMP client, the
Read Only feature must be disabled. When the Read Only feature is enabled,
you will not be able to issue configuration commands to the NBB unit via SNMP.
• Authentication / Privacy: Configures the Authentication and Privacy features
for SNMPv3 communication. The Authentication / Privacy parameter offers two options, which function as follows: 1. Auth/noPriv: An SNMPv3 username and password will be required at log in,
but encryption will not be used. (Default Setting.) 2. Auth/Priv: An SNMPv3 username and password will be required at log in, and
all messages will be sent using encryption.
• The Authentication / Privacy item is not available when the Version parameter is set to V1/V2. • If the Version Parameter is set to V1/V2/V3 (all) and Authentication / Privacy parameter is set to "Auth/Priv", then only V3 data will be encrypted. • The NBB does not support "noAuth/noPriv" for SNMPv3 communication. • SNMPv3 User Name: Sets the User Name for SNMPv3. Note that this option is
not available when the Version parameter is set to V1/V2. (Default = undefined.) • SNMPv3 Password: Sets the password for SNMPv3. Note that this option is not
available when the Version parameter is set to V1/V2. (Default = undefined.) • SNMPv3 Password Confirm: This prompt is used to confirm the SNMPv3
password that was entered at the prompt above. Note that this option is not available when the Version parameter is set to V1/V2. (Default = undefined.) • Authentication Protocol: This parameter determines which authentication protocol
will be used. The NBB supports both MD5 and SHA1 authentication. (Default = MD5.) • The Authentication Protocol that is selected for the NBB must match the protocol that your SNMP client will use when querying the NBB unit. • The Authentication Protocol option is not available when the Version parameter is set to V1/V2 • SNMP Contact: (Default = undefined.)
• SNMP Location: (Default = undefined.)
• Read Only Community: Note that this parameter is not available when the SNMP
Version is set to V3. (Default = Public.) • Read/Write Community: Note that this parameter is not available when the SNMP
Version is set to V3. (Default = Public.) 5.9.7. SNMP Trap Parameters
These menus are used to select parameters that will be used when SNMP traps are
sent. For more information on SNMP Traps, please refer to Section 12. In the Text
Interface, the SNMP Trap Parameters menu is accessed via the Network Configuration
menu. In the Web Browser Interface, the SNMP Trap Parameters menu is accessed via
the flyout menus under the Network Configuration link. The SNMP Trap Parameters
menu allows the following parameters to be defined:
• In the Text Interface, SNMP Trap parameters are defined via two separate menus that are accessed via either the /N command (IPv4) or the /N6
command (IPv6.) • In the web browser interfrace, SNMP Trap parameters are defined via two separate submenus that are accessed via the IPv4 or IPv6 flyout menus, under the SNMP Traps link. • SNMP Manager 1: The IP Address for the first SNMP Manager. For more
information, please refer to Section 12. (Default = Undefined.) Note: In order to enable the SNMP Trap feature, you must define at least one
SNMP Manager.
• SNMP Manager 2: (Default = Undefined.)
• Trap Community: (Default = Public.)
• Trap Version: The assigned security level for SNMP traps. (Default = V1.)
• Trap Engine ID: The V3 SNMP agent's unique identifier. (Default = Undefined.)
• Ping Test: Allows you to ping the IP addresses or domain names defined via the
SNMP Manager 1 and SNMP Manager 2 prompts in order to check that a valid IP address or domain name has been entered.
• In order for the Ping Test feature to function, your network and/or firewall
must be configured to allow ping commands. • In addition to the Ping Test feature, the /TEST command in the Text Interface or the "Test" option in the Web Browser Interface can also be used to ping the currently defined SNMP Managers in order to make certain that the IP addresses are responding. 5.9.8. LDAP Parameters
The NBB supports LDAP (Lightweight Directory Access Protocol,) which allows
authentication via the "Active Directory" network Directory Service. When LDAP is
enabled and properly configured, command access rights can be granted to new users
without the need to define individual new accounts at each NBB unit, and existing users
can also be removed without the need to delete the account from each NBB unit. This
type of authentication also allows administrators to assign users to LDAP groups, and
then specify which plugs the members of each group will be allowed to control at each
NBB unit.
In order to apply the LDAP feature, you must first define User Names and associated Passwords and group membership via your LDAP server, and then access the NBB command mode to configure LDAP settings and define port access rights and command access rights for each group specified at the LDAP server. To access the LDAP Parameters menu, login to NBB command mode using a password that permits Administrator level commands. In the Text Interface, the LDAP Parameters menu is accessed via the Network Configuration menu (/N for IPv4 parameters or /N6 for IPv6 parameters.) In the Web Browser Interface, both IPv4 and IPv6 parameters are defined via a single LDAP Parameters menu, which is accessed via the flyout menus under the Network Configuration link.
• In the Web Browser Interface, both IPv4 and IPv6 parameters for LDAP are defined via a single menu. In the Text Interface IPv4 parameters are defined via the /N command and IPv6 parameters are defined via the /N6 command. • Plug access rights are not defined at the LDAP server. They are defined via the LDAP Group configuration menu on each NBB unit and are specific to that NBB unit alone. • When LDAP is enabled and properly configured, LDAP authentication will supersede any passwords and access rights that have been defined via the NBB user directory. • If no LDAP groups are defined on a given NBB unit, then access rights will be determined as specified by the "default" LDAP group. • The "default" LDAP group cannot be deleted. The LDAP Parameters Menu allows you to define the following parameters: • Enable: Enables/disables LDAP authentication. (Default = Off)
• Primary Host IPv4: Defines the IP address or domain name for the primary LDAP
server when IPv4 protocol is used to communicate with the NBB unit. (Default = Undefined.) • Primary Host IPv6: Defines the IP address or domain name for the primary LDAP
server when IPv6 protocol is used to communicate with the NBB unit. (Default = Undefined.) • Secondary Host IPv4: Defines the IP address or domain name for the secondary
(fallback) LDAP server when IPv4 protocol is used. (Default = Undefined.) • Secondary Host IPv6: Defines the IP address or domain name for the secondary
(fallback) LDAP server when IPv6 protocol is used. (Default = Undefined.) • LDAP Port: Defines the port that will be used to communicate with the LDAP
server. (Default = 389.) • TLS/SSL: Enables/Disables TLS/SSL encryption. Note that when TLS/SSL
encryption is enabled, the LDAP Port should be set to 636. (Default = Off.) • Bind Type: Sets the LDAP bind request password type. In the Text Interface, when
the Bind Type is set to "Kerberos," the LDAP menu will include an additional prompt used to select Kerberos parameters. In the Web Interface, Kerberos parameters are defined using the prompts at the bottom of the menu. (Default = Simple.) • Search Bind DN: The username that will be allowed to search the LDAP directory.
(Default = Undefined.) • Search Bind Password: The Password for the user who is allowed to search the
LDAP directory. (Default = Undefined.) • User Search Base DN: The directory location for user searches.
(Default = Undefined.) • User Search Filter: Selects the attribute that lists the user name. Note that this
attribute should always end with "=%S" (no quotes.) (Default = Undefined.)
• Group Membership Attribute: Selects the attribute that list group membership(s).
(Default = Undefined.) • Group Membership Value Type: (Default = DN.)
• Fallback: Enables/Disables the LDAP fallback feature. When enabled, the NBB
will revert to it's own internal user directory if no defined users are found via the LDAP server. In this case, port access rights will then be granted as specified in the default LDAP group. (Default = Off.) • Kerberos Setup: Kerberos is a network authentication protocol, which provides
a secure means of identity verification for users who are communicating via a non-secure network. In the Text Interface, Kerberos parameters are selected via a submenu that is only available when Kerberos is selected as Bind Type. In the Web Browser Interface, Kerberos parameters are defined via the main LDAP Parameters menu. The following parameters are available: Port: (Default = 88.)
Realm: (Default = Undefined.)
Key Distribution Centers (KDC1 through KDC5): (Default = Undefined.)
Domain Realms 1 through 5: (Default = Undefined.)
• LDAP Group Setup: Provides access to a submenu, which is used to define LDAP
Groups as described in the Sections 5.9.8.1 through 5.9.8.4.
• Debug: This option is used to assist WTI Technical Support personnel with the
diagnosis of LDAP issues. (Default = Off.) • Ping Test: Allows you to ping IP addresses or domain names that have been
defined via the LDAP Parameters menus in order to check that a valid IP address or domain name has been entered.
• In order for the Ping Test feature to function, your network and/or firewall must be configured to allow ping commands. • In addition to the Ping Test feature, the /TEST command in the Text Interface or the "Test" option in the Web Browser Interface can also be used to ping any user defined IP address in order to make certain that the IP address is responding. 5.9.8.1. Adding LDAP GroupsOnce you have defined users and passwords via your LDAP server, and assigned users to LDAP Groups, you must then grant command and port access rights to each LDAP Group at each individual NBB unit. In order to Add an LDAP Group, you must access the NBB command mode using a password that permits Administrator Level commands. The Add LDAP Group menu allows the following to be defined: • Group Name: Note that this name must match the LDAP Group names that you
have assigned to users at your LDAP server. (Default = Undefined.) • Access Level: Sets the command access level to either Administrator, SuperUser,
User or ViewOnly. For more information on Access Levels, please refer to Section 5.4.1. (Default = User.) • Port Access: Enables/disables this LDAP Group's access to the serial Setup Port.
(Default = Disabled.) • Plug Access: Determine which plugs members of this group will be allowed to
control. (Default = All Plugs Off.) • Plug Group Access: Determines which plug groups the members of this LDAP
Group will be allowed to control. (Default = Undefined.) • Service Access: Determines whether members of this LDAP group will be allowed
to access command mode via the serial Setup Port, via Telnet/SSH or via both methods. (Default = Serial Port = On, Telnet/SSH = On, Web = On.) • Current/Power Metering: Determines whether or not members of this LDAP Group
will be allowed to view current, voltage and temperature readings.
Note: After you have defined LDAP Group parameters, make certain to save
changes before proceeding. In the Web Browser Interface, click on the "Add
LDAP Group" button to save parameters; in the Text Interface, press the [Esc]
key several times until the NBB displays the "Saving Configuration" message.
5.9.8.2 Viewing LDAP GroupsIf you need to examine an existing LDAP group definition, the "View LDAP Groups" function can be used to review the group's parameters and Plug Access Settings.
5.9.8.3. Modifying LDAP GroupsIf you want to modify an existing LDAP Group in order to change parameters or plug access rights, the "Modify LDAP Group" function can be used to reconfigure group parameters. To Modify an existing LDAP Group, you must access the NBB command mode using a password that permits access to Administrator Level commands. Once you have accessed the Modify LDAP Group menu, use the menu options to redefine parameters in the same manner that is used for the Add LDAP Group menu, as discussed in Section 5.9.8.1.
Note: After you have finished modifying LDAP Group parameters, make certain
to save the changes before proceeding. In the Web Browser Interface, click on
the "Modify LDAP Group" button to save parameters; in the Text Interface, press
the [Esc] key several times until the NBB displays the "Saving Configuration"
message and the cursor returns to the command prompt.
5.9.8.4. Deleting LDAP GroupsThe Delete LDAP Group function is used to delete LDAP Groups that are no longer in use. In order to Delete an existing LDAP Group, you must access the NBB command mode using a password that permits access to Administrator Level commands.
5.9.9. TACACS Parameters
The TACACS Configuration Menus offer the following options:
• Enable: Enables/disables the TACACS feature at the Network Port. (Default = Off.)
• Primary Address: Defines the IP address or domain name (up to 64 characters)
for your primary TACACS server. (Default = Undefined.) • Secondary Address: Defines the IP address or domain name (up to 64 characters)
for your secondary, fallback TACACS server (if present.) (Default = Undefined.) • Secret Word: Defines the shared TACACS Secret Word for both TACACS servers.
(Default = Undefined.) • Fallback Timer: Determines how long the NBB will continue to attempt to contact
the primary TACACS Server before falling back to the secondary TACACS Server. (Default = 15 Seconds.) • Fallback Local: Determines whether or not the NBB will fallback to its own
password/username directory when an authentication attempt fails. When enabled, the NBB will first attempt to authenticate the password by checking the TACACS Server; if this fails, the NBB will then attempt to authenticate the password by checking its own internal username directory. This parameter offers three options: Off: Fallback Local is disabled (Default.)
On (All Failures): Fallback Local is enabled, and the unit will fallback to it's own
internal user directory when it cannot contact the TACACS Server, or when a password or username does not match the TACACS Server.
On (Transport Failure): Fallback Local is enabled, but the unit will only fallback
to it's own internal user directory when it cannot contact the TACACS Server.
• Authentication Port: The port number for the TACACS function. (Default = 49.)
• Default User Access: When enabled, this parameter allows TACACS users to
access the NBB command mode without first defining a TACACS user account on the NBB. When new TACACS users access the NBB command mode, they will inherit the default Access Level, Port Access, Plug Access, Plug Group Access, Service Access and Current/Power Metering parameters that are defined via the items listed below: (Default = On.) Enable: Enables/disables the Default User Access function. (Default = On.)
Access Level: Determines the default Access Level setting for new TACACS
users. This option can set the default access level for new TACACS users to "Administrator", "SuperUser", "User" or "ViewOnly." For more information on Command Access Levels, please refer to Section 5.4.1 and Section 17.2. (Default = User.) Port Access: Determines the default Port Access setting for new TACACS users.
The Port Access setting determines whether or not the account will be allowed to connect to the serial Setup Port. (Defaults; Administrator and SuperUser = Always Enabled, User = Disabled.) Note: ViewOnly level accounts cannot be granted access to the Setup Port.
Plug Access: Determines the default Plug Access setting for new TACACS
users. (Defaults; Administrator and SuperUser = All Plugs On, User = All Plugs Off, ViewOnly = All Plugs Off.) • Administrator and SuperUser level accounts always have access to all plugs.
• User level accounts will only have access to the plugs that are defined via the "Plug Access" parameter. • ViewOnly accounts are not allowed to invoke switching and reboot Plug Group Access: Determines the default Plug Group Access setting for
new TACACS users. For more information on Plug Groups, please refer to Section 5.6. (Defaults; Administrator and SuperUser = All Plug Groups On, User = All Plug Groups Off, ViewOnly = All Plug Groups Off.) • In order to use this feature, you must first define at least one Plug Group as described in Section 5.6. • Administrator and SuperUser level accounts will always have access to all plug groups. • User Level accounts will only have access to the plug groups that are defined via the Plug Group Access parameter. • ViewOnly accounts are not allowed to invoke switching and reboot Service Access: Selects the default Service Access setting for new TACACS
users. The Service Access setting determines whether each account will be able to access command mode via Serial Port, Telnet/SSH or Web. For example, if Telnet/SSH Access is disabled for an account, then the account will not be able to access command mode via Telnet or SSH. (Default = Serial Port = On, Telnet/SSH = On, Web = On.) Current/Power Metering: Selects the default enable/disable status for the
Current/Power Metering setting. When Current/Power Metering is disabled, an account will not be able to view current or power readings or display current or power history. Note that in order for accounts to be able to display these logs, Current and Power Metering must be enabled via the Systems Parameters menu as described in Section 5.3. (Default = On.) • Ping Test (Ping TACACS Servers): Allows you to ping IP addresses or domain
names that have been defined via the TACACS Parameters menus in order to check that a valid IP address or domain name has been entered.
• In order for the Ping Test feature to function, your network and/or firewall must be configured to allow ping commands. • In addition to the Ping Test feature, the /TEST command in the Text Interface or the "Test" option in the Web Browser Interface can also be used to ping any user defined IP address in order to make certain that the IP address is responding. 5.9.10. RADIUS Parameters
In the Text Interface, the RADIUS Parameters menu is accessed via the Network
Configuration menu (/N for IPv4 parameters or /N6 for IPv6 parameters.) In the Web
Browser Interface, both IPv4 and IPv6 parameters are defined via a single RADIUS
Parameters menu, which is accessed via the flyout menus under the Network
Configuration link. The RADIUS Configuration Menus offer the following options:
• Enable: Enables/Disables the RADIUS feature at the Network Port. (Default = Off.)
• Primary Address IPv4: Defines the IP address or domain name for your primary
RADIUS server when IPv4 protocol is used. (Default = Undefined.) • Primary Address IPv6: Defines the IP address or domain name for your primary
RADIUS server when IPv6 protocol is used. (Default = Undefined.) • Primary Secret Word: Defines the RADIUS Secret Word for the primary RADIUS
server. (Default = Undefined.) • Secondary Address IPv4: Defines the IP address or domain name for your
secondary, fallback RADIUS server when IPv4 protocol is used. (Default = Undefined.) • Secondary Address IPv6: Defines the IP address or domain name for your
secondary, fallback RADIUS server when IPv6 protocol is used. (Default = Undefined.) • Secondary Secret Word: Defines the RADIUS Secret Word for the secondary
RADIUS server. (Default = Undefined.) • Fallback Timer: Determines how long the NBB will continue to attempt to contact
the primary RADIUS Server before falling back to the secondary RADIUS Server. (Default = 3 Seconds.) • Fallback Local: Determines whether or not the NBB will fallback to its own
password/username directory when an authentication attempt fails. When enabled, the NBB will first attempt to authenticate the password by checking the RADIUS Server; if this fails, the NBB will then attempt to authenticate the password by checking its own internal username directory. This parameter offers three options: Off: Fallback Local is disabled (Default.)
On (All Failures): Fallback Local is enabled, and the unit will fallback to it's
own internal user directory when it cannot contact the Radius Server, or when a password or username does not match the Radius Server.
On (Transport Failure): Fallback Local is enabled, but the unit will only fallback
to it's own internal user directory when it cannot contact the Radius Server.
• Retries: Determines how many times the NBB will attempt to contact the RADIUS
server. Note that the retries parameter applies to both the Primary RADIUS Server and the Secondary RADIUS Server. (Default = 3.) • Authentication Port: The Authentication Port number for the RADIUS function.
(Default = 1812.) • Accounting Port: The Accounting Port number for the RADIUS function.
(Default = 1813.) • Debug: (Text Interface Only) When enabled, the NBB will put RADIUS debug
information into Syslog. (Default = Off.) • Ping Test: Allows you to ping IP addresses or domain names that have been
defined via the RADIUS Parameters menus in order to check that a valid IP address or domain name has been entered.
• In order for the Ping Test feature to function, your network and/or firewall must be configured to allow ping commands. • In addition to the Ping Test feature, the /TEST command in the Text Interface or the "Test" option in the Web Browser Interface can also be used to ping any user defined IP address in order to make certain that the IP address is responding. Dictionary Support for RADIUS The RADIUS dictionary file can allow you to define users and assign command access rights and plug access rights from a central location. The RADIUS dictionary file, "dictionary.wti" is included on the CDROM along with this user's guide. To install the dictionary file on your RADIUS server, please refer to the documentation provided with your server; some servers will require the dictionary file to reside in a specific directory location, others will require the dictionary file to be appended to an existing RADIUS dictionary file. The WTI RADIUS dictionary file provides the following commands: • WTI-Super - Sets the command access level for the user. This command provides
the following arguments: 0 = ViewOnly
2 = SuperUser
3 = Administrator
For example, to set the access level to "SuperUser", the command line would be: • WTI-Plug-Access - Determines which plug(s) the user will be allowed to access.
This command provides an argument that consists of a character string, with one character for each the NBB's switched outlets. The following options are available: 0 = Off (Deny Access)
1 = On (Allow Access)
For example, to allow access to Plugs 2 and 4, the command line would be: • WTI-Group-Access - Determines which plug group(s) the user will be allowed
to access. The argument for this command includes a character for each, defined plug group. The first character in the string is used to represent the first plug group defined, and the last character in the string represents the last plug group defined. The following options are available for each plug group: 0 = Off (Deny Access)
1 = On (Allow Access)
For example, to allow access to the first three defined plug groups out of a total of six defined plug groups, the command line would be: Example:
The following command could be used to set the command access level to "User", allow
access to Serial Ports 1, 3, 5 and 7 and Plugs 1 and 2, and also allow access to the first
two of five defined plug groups:
tom Auth-Type:=Local, User-Password=="tom1"
Login-Service=Telnet,
Login-TCP-Port=Telnet,
User-Name="HARRY-tom",
WTI-Super="1",
WTI-Plug-Access="11000000",
5.9.11. Email Messaging Parameters
The Email Messaging menu is used to define parameters for email messages that
the NBB can send to notify you when an alarm is triggered. To define email message
parameters, you must access the NBB Command Mode using a password that permits
access to Administrator Level commands and then proceed as follows:
• Text Interface: Type /N (for IPv4 parameters) or /N6 (for IPv6 parameters) and
press [Enter] to access the Network Configuration Menu. Key in the number for the
Email Messaging option and press [Enter] to display the Email Messaging Menu.
• Web Browser Interface: Place the cursor over the "Network Configuration" link on
the left hand side of the screen. When the fly-out menu appears select either the link for IPv4 parameters or IPv6 parameters to display the Email Messaging Menu.
The Email Messaging menu offers the following options: • Enable: Enables/Disables the Email Messaging feature. When disabled, the NBB
will not be able to send email messages when an alarm is generated. (Default = Off.) • SMTP Server: This prompt is used to define the address of your SMTP Email
server. (Default = Undefined.) • Port Number: Selects the TCP/IP port number that will be used for email
connections. (Default = 25.) • Domain: The domain name for your email server. (Default = Undefined.)
Note: In order to use domain names, you must first define Domain Name
Server parameters as described in Section 5.9.5.
• User Name: The User Name that will be entered when logging into your email
server. (Default = Undefined.) • Password: The password that will be used when logging into your email server.
(Default = undefined) • Auth Type: The Authentication type; the NBB allows you to select None, Plain,
Login, or CRAM-MD5 Authentication. (Default = Plain) • From Name: The name that will appear in the "From" field in email sent by the
NBB. (Default = undefined) • From Address: The email address that will appear in the "From" field in email sent
by the NBB. (Default = undefined) • To Address: The address(es) that will receive email messages generated by the
NBB. Note that up to three "To" addresses may be defined, and that when Alarm Configuration parameters are selected as described in Section 7, you may then designate one, two or all three of these addresses as recipients for email messages that are generated by the alarms. (Default = undefined) • Send Test Email: Sends a test email, using the parameters that are currently
defined for the Email configuration menu.
5.10. Save User Selected Parameters
It is strongly recommended to save all user-defined parameters to a file as described in Section 15. This will allow quick recovery in the event of accidental deletion or reconfiguration of port parameters.
When changing configuration parameters via the Text Interface, make certain that the
NBB has saved the newly defined parameters before exiting from command mode.
To save parameters, press the [Esc] key several times until you have exited from all
configuration menus and the NBB displays the "Saving Configuration" menu and the
cursor returns to the command prompt. If newly defined configuration parameters
are not saved prior to exiting from command mode, then the NBB will revert to the
previously saved configuration after you exit from command mode.
5.10.1. Restore Configuration
If you make a mistake while configuring the NBB unit, and wish to return to the
previously saved parameters, the Text Interface's "Reboot System" command (/I) offers
the option to reinitialize the unit using previously backed up parameters. This allows you to reset the unit to previously saved parameters, even after you have changed parameters and saved them.
• The NBB will automatically backup saved parameters once a day, shortly after Midnight. This configuration backup file will contain only the most recently saved NBB parameters, and will be overwritten by the next night's daily backup. • When the /I command is invoked, a submenu will be displayed which offers several Reboot options. Option 5 is used to restore the configuration backup file. The date shown next to option 5 indicates the date that you last changed and saved unit parameters. • If the daily automatic configuration backup has been triggered since the configuration error was made, and the previously saved configuration has been overwritten by newer, incorrect parameters, then this function will not be able to restore the previously saved (correct) parameters. To restore the previously saved configuration, proceed as follows: 1. Access command move via the Text Interface, using a username/password that permits access to Administrator level commands (see Section 5.1.1.) 2. At the NBB command prompt, type /I and press [Enter]. The NBB will display a
submenu that offers several different reboot options.
3. At the submenu, choose Item 5 (Reboot & Restore Last Known Working Configuration. Key in the number for the desired option, and then press [Enter].
4. The NBB will reboot and previously saved parameters will be restored.
6. Reboot Options
In addition to performing reboot cycles in response to commands, the NBB can also be configured to automatically reboot outlets when an attached device does not respond to a Ping command (Ping-No-Answer Reboot) or according to a user defined schedule (Scheduled Reboot.) • Ping-No-Answer Reboot: When the Ping-No-Answer feature is enabled, the NBB
will Ping a user selected IP address at regular intervals. If the IP address does not respond to the Ping command, the NBB will reboot one or more user selected outlet(s). Typically, this feature is used to reboot devices when they cease to respond to the Ping command.
• Scheduled Reboot: A scheduled reboot is used to initiate a reboot cycle at a user
selected time and day of the week. When properly configured and enabled, the NBB will reboot one or more outlets on a daily or weekly basis. The Scheduled Reboot feature can also be used to switch outlet(s) Off at a user selected time, and then switch them back On again at a later, user selected time.
This section describes the procedure for configuring and enabling Ping-No-Answer Reboots and Scheduled Reboots.
Note: When defining parameters via the Text Interface, make certain to press
the [Esc] key to completely exit from the configuration menus and save newly
defined parameters. When parameters are defined via the Text Interface, newly
defined parameters will not be saved until the "Saving Configuration" message is
displayed.
Reboot Options 6.1. Ping-No-Answer Reboot
A Ping-No-Answer Reboot can be used to reboot one or more outlets when an attached device does not respond to a Ping Command. In addition, the Ping-No-Answer Reboot feature can also be configured to send an email, Syslog Message or SNMP Trap to notify you whenever a Ping-No-Answer Reboot occurs. Please refer to Section 7.5 for instructions on setting up email alarm notification for Ping-No-Answer reboots.
To set up a Ping-No-Answer Reboot, you must access command mode using a password that permits Administrator level commands. In the Text Interface, the Ping-No-Answer configuration menu is accessed via the Reboot Options menu (/RB). In the Web Browser Interface, the Ping-No-Answer configuration menu is accessed via the Reboot Options link. The Ping-No-Answer configuration menu can be used to Add, Modify, View or Delete Ping-No-Answer Reboot functions.
Note: In order for the Ping-No-Answer Reboot feature to work properly, your
network and/or firewall, as well as the device at the target IP address must be
configured to allow ping commands.
6.1.1. Adding Ping-No-Answer Reboots
Up to 54 Ping-No-Answer Reboots can be defined. The Add Ping-No-Answer menu is
used to define the following parameters for each new Ping-No-Answer Reboot:
• IP Address or Domain Name: The IP address or Domain Name for the device
that you wish to Ping. When the device at this address fails to respond to the Ping command, the NBB will reboot the selected outlets. (Default = undefined) • In order to use domain names, DNS Server parameters must first be defined as described in Section 5.9.5. • In the Text Interface, a submenu will be displayed that allows the user to choose either IPv4 protocol or IPv6 protocol. • In the Web Browser Interface, the Add Ping-No-Answer Reboot menu includes a menu item that is used to select IPv4 protocol or IPv6 protocol. • Protocol: (Web Interface Only) Allows definition of an IPv4 format IP Address or
an IPv6 format IP Address. Note that if desired, both an IPv4 and an IPv6 format IP Address may be defined. (Default = IPv4) • Ping Interval: Determines how often the Ping command will be sent to the
selected IP Address. The Ping Interval can be any whole number, from 1 to 3,600 seconds. (Default = 60 Seconds) Note: If the Ping Interval is set lower than 20 seconds, it is recommended to
define the "IP Address or Domain Name" parameter using an IP Address rather
than a Domain Name. This ensures more reliable results in the event that the
Domain Name Server is unavailable.
• Interval After Failed Ping: Determines how often the Ping command will be sent
after a previous Ping command receives no response. (Default = 10 Seconds) Reboot Options • Ping Delay After PNA Action: Determines how long the NBB will wait to send
additional Ping commands, after a Ping-No-Answer Reboot has been initiated. Typically, this option is used to allow time for a device to fully "wake up" after a Ping-No-Answer Reboot before attempting to Ping the device again. (Default = 15 Minutes) • Consecutive Failures: Determines how many consecutive failures of the Ping
command must be detected in order to initiate a Ping-No-Answer Reboot. For example, if this value is set to "3", then after three consecutive Ping failures, a Ping-No-Answer Reboot will be performed. (Default = 5) • Reboot: Enables/Disables the Ping-No-Answer Reboot function for the specified IP
address. When this item is disabled, the NBB will not reboot the specified outlet(s) when a Ping-No-Answer is detected. However, the NBB can continue to notify you via Email, Syslog Message and/or SNMP Trap, providing that parameters for these functions have been defined as described in Section 5.9 and email notification for the Ping-No-Answer function has been enabled as described in Section 7.5. (Default = No) • In order for Email/Text Message Notification to function, you must first define Email/Text Message parameters as described in Section 5.9.11. • In order for Syslog Message Notification to function, you must first define a Syslog Address as described in Section 5.9.2. • In order for SNMP Trap Notification to function, you must first define SNMP parameters as described in Section 5.9.7. • PNA Action: Determines how the NBB will react when the IP address fails to
respond to a ping. The NBB can either continuously reboot the specified outlet(s) and send notification until the IP address responds and the Ping-No-Answer Reboot is cleared (Continuous Alarm/Reboot), or the NBB can reboot the specified outlet(s) and send notification only once each time the Ping-No-Answer Reboot is initially triggered (Single Alarm/Reboot.) (Default = Continuous Alarm/Reboot) • Plug Access: Determines which outlet(s) will be rebooted when the IP address for
this Ping-No-Answer operation does not respond to a Ping command. Note that in the Text Interface, Plug Access is defined via a separate submenu; in the Web Browser Interface, Plug Access is defined via a drop down menu, accessed by clicking on the "plus" sign in the "Configure Plug Access" field. (Default = undefined) • Plug Group Access: Determines which Plug Group(s) the Ping-No-Answer
Reboot for this IP Address will be applied to. Note that in the Text Interface, Plug Group Access is defined via a separate submenu; in the Web Browser Interface, Plug Group Access is defined via a drop down menu, which may be accessed by clicking on the "plus" sign. (Default = undefined) Reboot Options • Ping Test: Sends a test Ping command to the IP Address defined for this Ping-No-
Answer Reboot.
• In order for the Ping Test function to work properly, your network and/or firewall as well as the device at the target IP address must be configured to allow ping commands. • After you have finished defining or editing Ping-No-Answer Reboot parameters, make certain to save the changes before proceeding. In the
Web Browser Interface, click on the "Add Ping No Answer" button to save
parameters; in the Text Interface, press the [Esc] key several times until the
MPC displays the "Saving Configuration" message and the cursor returns to
the command prompt.
6.1.2. Viewing Ping-No-Answer Reboot Profiles
After you have defined one or more Ping-No-Answer Reboot profiles, you can review the
parameters selected for each profile using the View Ping-No-Answer feature. In order to
view the configuration of an existing Ping-No-Answer profile, you must access command
mode using a password that allows Administrator level commands and then use the
Ping-No-Answer menu's "View/Modify Ping-No-Answer" function.
6.1.3. Modifying Ping-No-Answer Reboot Profiles
After you have defined a Ping-No-Answer profile, you can modify the configuration of the

7. Alarm Configuration
When properly configured, NBB units can monitor rack temperature, ping command response and other factors at network installation sites. In addition, NBB series units can also measure and record current, power and voltage conditions. If user defined trigger levels for temperature are exceeded, the NBB can also perform load shedding; automatically shutting off user-designated power outlets in order to reduce the amount of heat generated in the rack. When temperatures return to acceptable levels, the NBB can then switch outlets back on again. The NBB can also perform load shedding when current consumption rises above user-defined threshold values. When any of the user-defined alarms are triggered, the NBB can send an alarm message to the proper personnel via Email, Syslog Message or SNMP trap.
This section describes the procedure for setting up the NBB to send alarm messages when critical situations are detected. For instructions regarding configuration of the Log function, please refer to Section 5.3.3.
• In order to send alarm notification via email, email addresses and parameters must first be defined as described in Section 5.9.11. Email alarm notification will then be sent for all alarms that are enabled as described in this Section. • In order to send alarm notification via Syslog Message, a Syslog address must first be defined as described in Section 5.9.2. Once the Syslog address has been defined, Syslog Messages will be sent for every alarm that is discussed in this Section, providing that the Trigger Enable parameter for the alarm has been set to "On." • In order to send alarm notification via SNMP Trap, SNMP Trap parameters must first be defined as described in Section 5.9.7. Once SNMP Trap Parameters have been defined, SNMP Traps will be sent for every alarm that is discussed in this Section, providing that the Trigger Enable parameter for the alarm has been set to "On." • When defining parameters via the Text Interface, make certain to press the [Esc] key to completely exit from the configuration menu and save newly
defined parameters. When parameters are defined via the Text Interface,
newly defined parameters will not be saved until the "Saving Configuration"
message is displayed.
To configure the NBB Alarm functions, access the command mode using a password
that allows Administrator level commands and then activate the Alarm Configuration
menu (in the Text Interface, type /AC and press [Enter]; in the Web Browser Interface,
click on the "Alarm Configuration" link.) 7.1. The Over Current Alarms
The Over Current Alarms are designed to inform you when current consumption reaches or exceeds user-defined levels. Depending on the specific NBB model, NBB units can have up to two Over Current Alarms: • The Over Current Line (Initial) Alarm• The Over Current Line (Critical) Alarm The Initial alarm is used to provide notification when the level of current consumption reaches a point where you might want to investigate it, whereas the Critical alarm can provide notification when the level of current consumption approaches the maximum allowed level. The trigger level for the Initial alarm is generally set lower than the trigger levels for the Critical alarm.
When the user-defined trigger level for current load is exceeded, the NBB can automatically shut off power to non-essential devices ("Load Shedding") in order to decrease current load. After Load Shedding has taken place, the NBB can also restore power to the non-essential devices when current load drops to user-defined acceptable levels. For more information on Load Shedding, please refer to Section 7.1.1.
• In order for the NBB to provide alarm notification via Email, communication parameters must first be defined as described in Section 5.9.11. • In order for the NBB to provide alarm notification via Syslog Message, Syslog parameters must first be defined and Syslog Messages must be enabled as described in Section 5.9.2 and Section 11. • In order for the NBB to provide alarm notification via SNMP Trap, SNMP parameters must first be defined, and SNMP Traps must be enabled as described in Section 5.9.7 and Section 12. To configure the Over Current Alarms, access the NBB command mode using a password that permits Administrator Level commands, and then use the Alarm Configuration menu to select the desired alarm feature. Note that the configuration menus for both Over Current Line Alarms offer essentially the same set of parameters, but the parameters defined for each alarm are separate. Therefore, parameters defined for a Critical Alarm will not be applied to an Initial Alarm and vice versa. The Over Current Alarm Configuration menus offer the following parameters: • Trigger Enable: Enables/Disables the trigger for this alarm. When Disabled, this
alarm will be suppressed. (Default = On.) • When an alarm is generated, to cancel an alarm without correcting the condition that caused the alarm, simply toggle the Trigger Enable parameter Off and then back On again. • The Trigger Enable, Notify on Clear, Email Message and Address 1, 2 and 3 Parameters all include "Copy to All Triggers" options that allow you to enable/disable the corresponding parameter for all NBB alarms. For example, if the Over Current Alarm's Trigger Enable parameter is set to "On (Copy to All Triggers), then the triggers for all other NBB alarms will also be enabled. • Alarm Set Threshold: The trigger level for this alarm. When current load exceeds
the Alarm Set Threshold, the NBB can send an alarm and/or begin load shedding (if enabled.) Note that the Alarm Set Threshold is entered as a percentage of maximum capacity. (Defaults: Initial = 80%; Critical = 90%.) • Alarm Clear Threshold: Determines how low the current load must drop in order
for the Alarm condition to be cancelled and for load shedding recovery (if enabled) to occur. The Alarm Clear Threshold is entered as a percentage of maximum capacity. (Defaults: Initial Alarms = 70%; Critical Alarms = 80%.) • Resend Delay: Determines how long the NBB will wait to resend an email
message generated by this alarm, when the initial attempt to send the notification was unsuccessful. (Default = 60 Minutes.) • Notify Upon Clear: When this item is enabled, the NBB will send additional
notification when the situation that caused the alarm has been corrected. For example, when Notify Upon Clear is enabled, the NBB will first send notification when it detects that current consumption has exceeded the trigger value, and then send a second notification when it determines that the current consumption has fallen below the trigger value. (Default = On.) • Email Message: Enables/Disables email notification for this alarm. (Default = On.)
• Address 1, 2, and 3: These parameters are used to select which of the three email
addresses defined via the "Email Messages" menu (see Section 5.9.11) will receive the email alarm notification messages generated by this alarm. The Address parameters can be used to select one, or any combination of the addresses defined via the Email Messages menu. (Default = All On.) Note: If Email addresses have been previously defined, then the text under the
parameters will list the current, user selected email addresses.
• Subject: This parameter is used to define the text that will appear in the "Subject"
field for all email notification messages generated by the alarm. (Defaults = "Alarm: Over Current (Initial)" or "Alarm: Over Current (Critical)") • Load Shedding: Provides access to a submenu which is used to configure
and enable the Load Shedding feature for the Over Current Alarm. When Load Shedding is enabled and properly configured, the NBB will switch user-selected plugs On or Off whenever the current load exceeds the Alarm Set Threshold value. If the Auto Recovery feature is enabled, the NBB can also return these user-selected plugs to their prior status when current load falls below the Alarm Clear Threshold value. For more information on the Load Shedding Feature and Auto Recovery, please refer to Section 7.1.1.
7.1.1. Over Current Alarms - Load Shedding and Auto Recovery
The Load Shedding feature is used to switch specific, user-defined, non-essential plugs
On or Off whenever current load exceeds the Alarm Set Threshold value. This allows
the NBB to automatically shut Off plugs in order to reduce current load when the load
approaches user-defined critical levels. When the Auto Recovery feature is enabled,
the NBB can also automatically "undo" the effects of the Load Shedding feature when
current load again falls to a user-defined non-critical level.
Together, the Load Shedding and Auto Recovery features allow the NBB to shut off power to non-essential devices when the current load is too high, and then switch those same non-essential devices back On again when the load falls to an acceptable level.
The Load Shedding Configuration Menus allow you to define the following parameters: • The Load Shedding Configuration Menus for the Over Current Alarms offer essentially the same set of parameters, but parameters defined for each alarm are separate and unique. For example, parameters defined for Over Current (Initial) Alarm Load Shedding will not be applied to Over Current (Critical) Alarm Load Shedding and vice versa. • In the Web Browser Interface, the "Unit to Configure" and "Line" parameters are found in the Over Current Alarm configuration menus. • The "Unit to Configure," and "Line" parameters are used to determine which unit or line the Load Shedding functions will be applied to. • Unit to Configure: In some WTI power control products, this item is used to select
either a local unit or an auxiliary unit. In NBB series products, this option presently has no function. (Default = Local.) • Line A Load Shedding: Defines the Load Shedding actions that will be executed
when an Over Current Line Alarm is triggered at Line "A".
• Line B Load Shedding: Defines the Load Shedding actions that will be executed
when an Over Current Line Alarm is triggered at Line "B".
Note: The Line B Load Shedding parameter is not available on single line
NBB Models.
After selecting the desired line, use the following parameters to configure Load Shedding functions for the desired line.
• Enable: Enables/Disables Load Shedding for the corresponding alarm. When
enabled, the NBB will switch the user specified plugs whenever current load exceeds the Alarm Set Threshold value. (Default = Disable.) • Plug State: Determines whether the selected plugs/plug groups will be switched
On or Off when Load Shedding is enabled and current load exceeds the user-defined Alarm Set Threshold. For example, if the Plug State is "Off", then plugs or plug groups will be switched Off when the Alarm Set Threshold is exceeded. (Default = Off.) • Auto Recovery: Enables/Disables the Auto Recovery feature for the selected line.
When both Load Shedding and Auto Recovery are enabled, the NBB will return plugs to their former On/Off state after current load falls below the Alarm Clear Threshold value. This allows the NBB to "undo" the effects of Load Shedding after current load has returned to an acceptable level. (Default = Off.) • Plug Access: Determines which Plug(s) will be switched when current load
exceeds the Alarm Set Threshold and Load Shedding is triggered. For example, if plugs A1, A2 and A3 are selected, then these plugs will be switched On or Off whenever current load exceeds the Alarm Set Threshold. (Default = undefined.) • Plug Group Access: Determines which Plug Group(s) will be switched when the
Load Shedding feature is triggered. For example, if you have defined a Plug Group named "test", which includes Plugs B3, B4 and B5, and then selected the "test" Plug Group via the Plug Group Access parameter, then all of the plugs in the "test" Plug Group will be switched On or Off whenever the current load exceeds the Alarm Set Threshold. (Default = undefined.) Note: Plug Groups must first be defined (as described in Section 5.6) before
they will be displayed in the Load Shedding menu's Plug Group Access
submenu.
After setting parameters for a given line, you may also define additional parameters for the other line or lines (if present.) To set Load Shedding parameters for other lines, return to the Alarm Configuration menu and then repeat the procedure described in Section 7.1.1.
7.2. The Over Temperature Alarms
The Over Temperature Alarms are designed to inform you when the temperature level inside your equipment rack reaches or exceeds certain user-defined levels. There are two separate Over Temperature Alarms; the Initial Threshold alarm and the Critical Threshold Alarm.
Typically, the Initial Threshold alarm is used to notify you when the temperature within your equipment rack reaches a point where you might want to investigate it, whereas the Critical Threshold alarm is used to notify you when the temperature approaches a level that may harm equipment or inhibit performance. The trigger for the Initial Threshold alarm is generally set lower than the Critical Threshold alarm.
If the user-defined trigger levels for temperature are exceeded, the NBB can automatically shut off power to non-essential devices ("Load Shedding") in order to reduce the amount of temperature that is being generated within the rack. In addition, the Load Shedding feature can also be used to switch On additional components, such as fans or cooling systems in order to dissipate the excess heat. After Load Shedding has taken place, the Load Shedding Recovery feature can be used to return plugs to their previous state after the temperature drops to an acceptable level.
• In order for the unit to provide alarm notification via Email, communication parameters must first be defined as described in Section 5.9.11. • In order for the unit to provide alarm notification via Syslog Message, Syslog parameters must first be defined and Syslog Messages must be enabled as described in Section 5.9.2 and Section 11. • In order for the unit to provide alarm notification via SNMP Trap, SNMP parameters must first be defined, and SNMP Traps must be enabled as described in Section 5.9.7 and Section 12. To configure the Over Temperature Alarms, access the NBB command mode using a password that permits Administrator Level commands, and then use the Alarm Configuration menu to select the desired alarm feature. Both the Initial Threshold menus and Critical Threshold menus offer essentially the same parameters, but the parameters defined for each alarm are separate. Therefore, parameters defined for the Critical Threshold Alarm will not be applied to the Initial Threshold Alarm and vice versa. Both the Over Temperature (Initial Threshold) alarm and the Over Temperature (Critical Threshold) alarm offer the following parameters: • Trigger Enable: Enables/Disables the trigger for this alarm. When Disabled, this
alarm will be suppressed. (Default = On.) • When an alarm is generated, to cancel an alarm without correcting the condition that caused the alarm, simply toggle the Trigger Enable parameter Off and then back On again. • The Trigger Enable, Notify on Clear, Email Message and Address 1, 2 and 3 Parameters all include "Copy to All Triggers" options that allow you to enable/disable the corresponding parameter for all NBB alarms.

For more information on the Load Shedding Feature and Auto Recovery, please refer to Section 7.2.1.
7.2.1. Over Temperature Alarms - Load Shedding and Auto Recovery
For Over Temperature Alarms, the Load Shedding feature is used to switch specific,
user-defined plugs On or Off whenever temperature exceeds the Alarm Set Threshold
value. This allows the NBB to automatically shut Off non-essential devices in order to
reduce the temperature generated within the rack, or automatically switch On devices
such as fans or cooling systems in order to dissipate heat. When the Auto Recovery
feature is enabled, the NBB can also automatically "undo" the effects of the Load
Shedding feature when the temperature again falls to a user-defined non-critical level.
Note: Load Shedding Configuration Menus for both the Initial and Critical
Over Temperature Alarms offer essentially the same set of parameters, but
parameters defined for each alarm are separate and unique. For example,
parameters defined for Over Temperature (Initial) Alarm Load Shedding will not
be applied to Over Temperature (Critical) Alarm Load Shedding and vice versa.
The Load Shedding Configuration menus allow you to defined the following parameters: • Unit to Configure: In some WTI power control products, this item is used to select
either a local unit or an auxiliary unit. In NBB series products, this option presently has no function. (Default = Local.) • Configure Loadshedding for Unit: In the Text Interface, this item is used to
access the Load Shedding parameters listed below. In the Web Browser Interface, Load Shedding parameters are accessed via the "Load Shedding" button in the Temperature Alarm configuration menus.
• Enable: Enables/Disables Load Shedding for the Over Temperature Alarm.
When enabled, the NBB will switch the user specified plugs whenever the temperature exceeds the Alarm Set Threshold value. (Default = Disable.) • Plug State: Determines whether the selected plugs/plug groups will be switched
On or Off when Load Shedding is enabled and temperature exceeds the user-defined Alarm Set Threshold. For example, if the Plug State is set to "Off", then the selected plugs/plug groups will be switched Off when the Alarm Set Threshold is exceeded. (Default = Off.) • Auto Recovery: Enables/Disables the Auto Recovery feature for the selected
unit. When both Load Shedding and Auto Recovery are enabled, the NBB will return plugs to their former On/Off state after the temperature falls below the Alarm Clear Threshold value. This allows the NBB to "undo" the effects of the Load Shedding feature after the temperature returned to an acceptable level. (Default = Off.) • Plug Access: Determines which Plug(s) will be switched when the temperature
exceeds the Alarm Set Threshold and Load Shedding is triggered. For example, if plugs A1, A2 and A3 are selected, these plugs will be switched On or Off whenever the temperature exceeds the Alarm Set Threshold. (Default = undefined.) • Plug Group Access: Determines which Plug Group(s) will be switched when
the Load Shedding feature is triggered. (Default = undefined.) Note: In order to define Plug Group Access, you must first define at least one
Plug Group as described in Section 5.6.

9. Operation
The NBB offers two separate command interfaces; the Web Browser Interface and the Text Interface. Both interfaces offer essentially the same command options and features, and in most cases, parameters defined via the Web Browser Interface will also apply when communicating via the Text Interface (and vice versa.) 9.1. Operation via the Web Browser Interface
When using the Web Browser Interface, switching commands are invoked via the Plug Control Screen and Plug Group Control Screen.
9.1.1. The Plug Control Screen - Web Browser Interface
The Plug Control Screen lists the On/Off status of the NBB's Switched Outlets and
is used to control switching and rebooting of the outlets. To invoke power switching
commands, first access the NBB command mode (for more information, see
Section 5.1.) After accessing command mode, click on the "Plug Control" link on the left
hand side of the screen to display the Plug Control Screen.
When the Plug Control Screen appears, click the down arrow in the "Action" column for the desired outlet(s), then select the desired switching option from the dropdown menu and click on the "Confirm Plug Actions" button.
When the "Confirm Plug Actions" button is pressed, the NBB will display a screen which lists the selected action(s) and asks for confirmation before proceeding. To implement the selected action(s), click on the "Execute Plug Actions" button. The NBB will display a message which indicates that a switching operation is in progress, then display the Plug Status screen when the command is complete. At that time, the Status Screen will list the updated On/Off status of each plug.
• When switching and reboot operations are initiated, Boot/Sequence Delay times will be applied as described in Section 5.7.1. • If a switching or reboot command is directed to a plug that is already in the process of being switched or rebooted by a previous command, then the new command will be placed in a queue until the plug is ready to receive additional commands. • If the Status column in the Plug Control Screen includes an asterisk, this means that the corresponding outlet is busy completing a previously invoked command. • When the Plug Control Screen is displayed by an account that permits Administrator or SuperUser level commands, all switched outlets will be displayed. • When the Plug Control Screen is displayed by a User level account, the screen will only include the switched outlets that are allowed by the account. 9.1.2. The Plug Group Control Screen - Web Browser Interface
The Plug Group Control Screen is used to send switching and reboot commands to
the user-defined Plug Groups. As described in Section 5.6, Plug Groups allow you to
specify a group of outlets that are dedicated to a similar purpose or client, and then
direct switching commands to the group, rather than switching one plug at a time.
To apply power switching commands to Plug Groups, first access the NBB Command Mode (see Section 5.1.) Click on the "Plug Group Control" link on the left hand side of the screen to display the Plug Group Control Screen. When the Plug Group Control Screen appears, click the down arrow in the "Action" column for the desired Plug Group(s), then select the desired switching option from the dropdown menu and click on the "Confirm Plug Actions" button When the "Confirm Plug Group Actions" button is pressed, the NBB will display a screen which lists the selected action(s) and asks for confirmation before proceeding. To implement the selected plug group action(s), click on the "Execute Plug Group Actions" button. The NBB will display a screen which indicates that a switching operation is in progress, then display the Plug Status screen when the command is complete. At that time, the Status Screen will list the updated On/Off status of each plug.
• When switching and reboot operations are initiated, Boot/Sequence Delay times will be applied as described in Section 5.7.1. • If a switching or reboot command is directed to a plug that is already in the process of being switched or rebooted by a previous command, then the new command will be placed in a queue until the plug is ready to receive additional commands. • When the Plug Group Control Screen is displayed by an account that permits Administrator or SuperUser level commands, all user-defined Plug Groups will be displayed. • When the Plug Control Screen is displayed by a User level account, the screen will only include the Plug Groups that are specifically allowed for that account. 9.2. Operation via the Text Interface
When using the Text Interface, all switching functions are performed by invoking simple,
ASCII commands. The Text Interface includes a Help Menu, which summarizes all
available NBB commands. To display the Text Interface Help Menu, type /H and
Note: When the Help Menu is displayed by a SuperUser, User or ViewOnly
level account, the screen will not include commands that are only available to
Administrator level accounts.
9.2.1. Switching and Reboot Commands - Text Interface
These commands can be used to switch or reboot the NBB's switched plugs, and can
also be used to set plugs to the user-defined Power-Up Default values. Plugs may be
specified by name or number.
• If a switching or reboot command is directed to a plug that is already being switched or rebooted by a previous command, then the new command will be placed in a queue until the plug is ready to receive additional commands. • If an asterisk appears in the "Status" column for any given plug, this indicates that the plug is currently busy, processing a previously issued command. • Commands are not case sensitive. All commands are invoked by • When the Plug Control Screen is displayed by an account that permits Administrator level command access, all switched outlets will be displayed. • When you have accessed command mode using an account that permits Administrator or SuperUser level commands, then switching and reboot commands can be applied to all plugs. • When you have accessed command mode via a User level account, switching and reboot commands can only be applied to the plugs that are specifically allowed for that account. • If command confirmation is enabled, the NBB will display the Status Screen after commands are successfully completed. • When switching and reboot operations are initiated, Boot/Sequence Delay times will be applied as described in Section 5.7.1. • When used in On/Off/Reboot command lines, plug names and plug group names are not case sensitive.
When switching and reboot commands are executed, the NBB will display a "Sure?" prompt, wait for user response, and then complete the command. The unit will pause for a moment while the command is executed, and then return to the Plug Status Screen. To Switch Plugs, or initiate a Reboot Cycle, proceed as follows: 1. Switch Plug(s) On: Type /ON n and press [Enter]. Where "n" is the
alphanumeric number or name of the desired plug or Plug Group. For example: /ON A1 [Enter] or /ON ROUTER [Enter]
2. Switch Plug(s) Off: Type /OFF n and press [Enter]. Where "n" is the
alphanumeric number or name of the desired plug or Plug Group. Note that the
"/OFF" command can also be entered as "/OF". For example:
/OFF B2 [Enter] or /OF ROUTER [Enter]
3. Reboot Plug(s): Type /BOOT n and press [Enter]. Where "n" is the alphanumeric
number or name of the desired plug or Plug Group. Note that the "/BOOT"
command can also be entered as "/BO". For example:
/BOOT B3 [Enter] or /BO ATMSWTCH [Enter]
4. Set All Plugs to Power Up Defaults: Type /DPL and press [Enter]. All plugs
permitted by your account will be set to their default On/Off status, which is defined via the Plug Parameters Menu as described in Section 5.7.
• When you have accessed command mode using an Administrator or SuperUser level account, the Default command will be applied to all plugs. • When you have accessed command mode using an account that permits only User level command access, the Default command will only be applied to the plugs specifically allowed by that account. • The /DPL command is not available in ViewOnly mode. 5. Suppress Command Confirmation Prompt: To execute a power switching
command without displaying the "Sure?" prompt, include the ",Y" option at the end
of the command line. For example: /ON ROUTER,Y or /BOOT B2,Y
9.2.2. Applying Commands to Several Plugs - Text Interface
As described below, switching and reboot commands can be applied to only one
Switched AC Outlet, or to an assortment of outlets.
• When switching and reboot operations are initiated, Boot/Sequence Delay times will be applied as described in Section 5.7.1. • When switching and reboot commands are invoked by a User level account, the command will only be applied to the plugs that are specifically allowed for that account. 1. Switch Several Plugs: To apply a command to several plugs, enter the numbers
of the desired plugs, separated by commas or plus signs. For example to switch plugs A1, A3, and A4 Off, enter either of the following commands: /OFF A1+A3+A4 [Enter]
/OFF A1,A3,A4 [Enter]
Note: In order for the "+" or "," operators to work, there must be no spaces
between the plug name or number and the plus sign or comma. 2. Switch a Series of Plugs: To apply a command to a series of plugs, enter the
numbers for the plugs that mark the beginning and end of the series, separated by a colon. For example to switch On plugs A1 through A4 enter the following: /ON A1:A4 [Enter]
3. All Plugs: To apply a command to all plugs, enter an asterisk in place of the name
or number. For example, to Boot all plugs, enter the following: /BO * [Enter]
9.3. The Automated Mode
The Automated Mode allows the NBB to execute switching and reboot commands, without displaying menus or generating response messages. Automated Mode is designed to allow the NBB to be controlled by a device which can generate commands to control power switching functions without human intervention.
When Automated Mode is enabled, the /ON, /OFF, /BOOT, /DPL and /X commands are executed without a "Sure?" confirmation prompt and without command response messages; the only reply to these commands is the command prompt, which is displayed when the command is complete.
Note that although Automated Mode can be enabled using either the Web Browser Interface or Text Interface, Automated Mode is designed primarily for users who wish to send ASCII commands to the NBB without operator intervention, and therefore does not generally apply to the Web Browser Interface. When Automated Mode is enabled, the Web Browser Interface can still be used to invoke On / Off / Boot commands.
• When Automated Mode is enabled, all NBB password security functions are disabled, and users are able to access System Level command functions (including the configuration menus) and control plugs without entering a password. • If you need to enable the Automated Mode, but want to restrict network access to NBB configuration menus, it is recommended to enable and configure the IP Security Function as described in Section 5.9.3. To enable/disable Automated Mode, access the System Parameters menu (see Section 5.3,) then set the "Automated Mode" option to "On". When Automated Mode is enabled, NBB functions will change as follows: 1. All Password Security Suppressed: When a user attempts to access command
mode, the password prompt will not be displayed at either the SetUp Port or the Network Port. Unless specifically restricted by the IP Security Function, all users will be allowed to access both switching and configuration functions, and all commands will be immediately accepted without the requirement to enter a password.
2. Status Screen Suppressed: The status screens will not be automatically
displayed after commands are successfully executed. Note however, that the /S command can still be invoked to display the status screen as needed.
3. "Sure?" Prompt Suppressed: All commands are executed without prompting for
user confirmation.
4. Error Messages Suppressed: If the [Enter] key is pressed without entering a
command, the NBB will not respond with the "Invalid Command" message. Note however, that an error message will still be generated if commands are invoked using invalid formats or arguments.
All other status display and configuration commands will still function as normal.
9.4. The SSH/Telnet Connect Function (Web Browser Interface Only)
The SSH/Telnet Connect function allows you to open an SSH Shell Session or Telnet Session without leaving the Web Browser interface. Once you have successfully opened an SSH Shell Session or Telnet Session, you can then use ASCII commands to configure and operate the NBB unit as described in Section 9.2 and Section 17.
9.4.1. Initiating an SSH Shell Session via the Web Browser Interface
To initiate an SSH Shell Session from the NBB Web Browser Interface, proceed as
follows:
1. Place the cursor over the "SSH/Telnet Connect" button on the left hand side of the screen. When the flyout menu appears, click on the SSH option.
Note: If the RSP displays a message that indicates that your browser does not
include the Java plugin, go to the Java website and download the latest version
of the Java plugin.
2. Start Java: Click on the File menu and select "Open Shell Session" 3. The NBB will display a prompt that asks the user to enter a valid username and host name (IP Address.) Key in the username and host name (IP address) using the following format and then click on the "OK" button: • The username entered must be a valid username that has been previously defined via the NBB User Directory as described in Section 5.5. • The IP Address (host name) can either be the address to the machine that you are currently communicating with via the Web Browser Interface, or you can enter the IP address for another NBB unit, providing that the username entered is present on the other NBB unit too. 4. After the username and host name are entered, the NBB will prompt you to enter your password. Key in the password that has been defined for the username entered in step 3 above and then click on the "OK" button.
5. The NBB will display the Circuit Status Screen, followed by the command prompt. You may now invoke NBB commands as described in Section 9.2 and 17.
6. To terminate the SSH Session, type /X and press [Enter].
9.4.2. Initiating a Telnet Session via the Web Browser Interface
To initiate a Telnet Session from the NBB Web Browser Interface, proceed as follows:
1. Place the cursor over the "SSH/Telnet Connect" button on the left hand side of the screen. When the flyout menu appears, click on the Telnet option.
Note: If the RSP displays a message that indicates that your browser does not
include the Java plugin, go to the Java website and download the latest version
of the Java plugin.
2. Log in to the Telnet Session: a) The NBB will display the "login" prompt. Key in a valid username that has been previously defined via the NBB User directory and then press [Enter].
b) The NBB will display the "password" prompt. Key in the valid password for the username entered above and then press [Enter].
• The username entered must be a valid username that has been previously defined via the NBB User Directory as described in Section 5.5. • The IP Address (host name) can either be the address to the machine that you are currently communicating with via the Web Browser Interface, or you can enter the IP address for another NBB unit, providing that the username entered is present on the other NBB unit too. 3. The NBB will display the Circuit Status Screen, followed by the command prompt. You may now invoke NBB commands as descrived in Section 9.2 and 17.
4. To terminate the Telnet Session, type /X and press [Enter].
9.5. Manual Operation
In addition to the command driven functions available via the Web Browser Interface and Text Interface, some NBB functions can also be controlled manually. For a summary of front panel control functions, please refer to Section 2.2.
9.6. Logging Out of Command Mode
When you have finished communicating with the NBB, it is important to always disconnect using either the "LogOut" link (Web Browser Interface) or the /X command (Text Interface), rather than by simply closing your browser window or communications program. When communicating via a PDA, use the PDA's "Close" function to disconnect and logout.
When you disconnect using the LogOut link or /X command, this ensures that the NBB has completely exited from command mode, and is not waiting for the inactivity timeout period to elapse before allowing additional connections.
10. SSH Encryption
In addition to standard Telnet protocol, the NBB also supports SSH connections, which provide secure, encrypted access via network. In order to communicate with the NBB using SSH protocol, your network node must include an appropriate SSH client.
Note that when the /K (Send SSH Key) command is invoked, the NBB can also provide you with a public SSH key, which can be used to streamline connection to the NBB when using SSH protocol.
Although you can establish an SSH connection to the unit without the public key, the public key provides validation for the NBB, and once this key is supplied to the SSH client, the client will no longer display a warning indicating that the NBB is not a recognized user when the client attempts to establish a connection.
The /K command uses the following format: /K <k> [Enter]
Where k is an argument that determines which type of public key will be displayed, and
the k argument offers the following options:
1. SSH1
For example, to obtain the public SSH key for an SSH2 RSA client, type /K 2 and then
press [Enter]. Note that when capturing the SSH key, you can either configure your
terminal application to receive the parameter file, or simply copy and paste the resulting
SSH key.
• Although the NBB does not support SSH1, the /K 1 command will still return a key for SSH1. • When capturing the SSH key, you can either configure your terminal application to receive the parameter file, or simply copy and paste the resulting key 11. Syslog Messages
The Syslog feature can create log records of each Alarm Event. As these event records are created, they are sent to a Syslog Daemon, located at an IP address defined via the Network Parameters menu.
If you wish to employ this feature, you must set the real-time clock and calendar via the System Parameters Menu, and define the IP address for the Syslog Daemon via the Network Port Configuration menu.
To configure the Syslog function, please proceed as follows: 1. Access command mode: Note that the following configuration menus are only
available to accounts that permit Administrator level commands.
2. System Parameters Menu: Access the System Parameters Menu as described in
Section 5.3, then set the following parameters: a) Set Clock and Calendar: Set the Real Time Clock and Calendar and/or
configure and enable the NTP server feature.
3. Network Parameters Menu: Access the Network Parameters Menu as described
in Section 5.9, then set the following parameters: a) Syslog IP Address: Determine the IP address for the device that will run the
Syslog Daemon, then use the Network Port Configuration menu to define the IP Address for the Syslog Daemon.
• The Network Parameters Menu allows the definition of IP addresses for both a primary Syslog Daemon and an optional secondary Syslog Daemon. • The Syslog Address submenu in the Text Interface includes a Ping Test function that can be used to ping the user-selected Syslog IP Address to verify that a valid IP address has been entered. In order for the Ping Test feature to function, your network and/or firewall must be configured to allow ping commands. 4. Syslog Daemon: In order to capture messages sent by the NBB, a computer must
be running a Syslog Daemon (set to UDP Port 514) at the IP address specified in Step 3 above.
Once the Syslog Address is defined, Syslog messages will be generated whenever one of the alarms discussed in Section 7 is triggered.
12. SNMP Traps
SNMP is an acronym for "Simple Network Management Protocol". The SNMP Trap function allows the NBB to send Alarm Notification messages to two different SNMP managers, each time one of the Alarms discussed in Section 7 is triggered.
• The SNMP feature cannot be configured via the SNMP Manager.
• SNMP reading ability is limited to the System Group.
• The SNMP feature includes the ability to be polled by an SNMP Manager.
• Once SNMP Trap Parameters have been defined, SNMP Traps will be sent each time an Alarm is triggered. For more information on Alarm Configuration, please refer to Section 7. To configure the SNMP Trap function, proceed as follows: 1. Access command mode using an account that permits Administrator level 2. SNMP Trap Parameters: Access the SNMP Trap Parameters Menu as described in
Section 5.9.7. Set the following: a) SNMP Managers 1 and 2: The address(es) that will receive SNMP Traps
that are generated by one of the Alarms discussed in Section 7. Consult your network administrator to determine the IP address(es) for the SNMP Manager(s), then use the Network Parameters menu to set the IP address for each SNMP Manager. Note that it is not necessary to define both SNMP Managers.
• To enable the SNMP Trap feature, you must define at least one SNMP Manager. SNMP Traps are automatically enabled when at least one SNMP Manager has been defined. • The SNMP Trap submenu includes a Ping Test function that can be used to ping the user-selected SNMP Managers to verify that a valid IP address has been entered. In order for the Ping Test feature to function, your network and/or firewall must be configured to allow ping commands. • Addresses for SNMP Managers can be defined in either IPv4 or IPv6 format, as described in Section 5.9.7. b) Trap Community: Consult your network administrator, and then use the
Network Parameters menus to set the Trap Community.
Once SNMP Trap Parameters have been defined, the NBB will send an SNMP Trap each time an alarm is triggered.
13. Operation via SNMP
If SNMP Access Parameters have been defined as described in Section 5.9.6, then you will be able to manage user accounts, control power and reboot switching and display unit status via SNMP. This section describes the procedure for SNMP communication with the NBB unit, and lists some common commands that can be employed to manage users, control switching and reboot actions and display unit status.
Note: SNMP Commands are not available when the IPS mode is active.
13.1. NBB SNMP Agent
The NBB's SNMP Agent supports various configuration, control, status and event notification capabilities. Managed objects are described in WTI-MPC-VMR-MIB.txt, which can be found in the user's guide archive on the WTI web site at: (http://www.wti.com/manuals.htm). The WTI-MPC-VMR-MIB.txt document can be compiled for use with your SNMP client.
13.2. SNMPv3 Authentication and Encryption
The major limitations of SNMPv2 were the failure to include proper username/password login credentials (v2 only used a password type of login, i.e., community name) and the lack of support for encryption of transmitted data. SNMPv3 addresses both of these shortcomings.
For SNMPv3, the NBB supports two forms of Authentication/Privacy: Auth/noPriv which requires a username/password, but does not encrypt data going over the internet and Auth/Priv which requires a username/password AND encrypts the data going over the internet using DES or AES (in the case of the NBB, the default encryption format for SNMPv3 is DES.) For the Password protocol, the SRM supports either MD5 or SHA1.
Operation via SNMP 13.3. Configuration via SNMP

This section describes the procedure for setting up a secure connection via an https web connection to the NBB.
Note: SSL parameters cannot be defined via the Web Browser Interface. In
order to set up SSL encryption, you must contact the NBB via the Text Interface.
There are two different types of https security certificates: "Self Signed" certificates and "Signed" certificates.
Self Signed certificates can be created by the NBB, without the need to go to an outside service, and there is no need to set up your domain name server to recognize the NBB. The principal disadvantage of Self Signed certificates, is that when you access the NBB command mode via the Web Browser Interface, the browser will display a message which warns that the connection might be unsafe. Note however, that even though this message is displayed, communication will still be encrypted, and the message is merely a warning that the NBB is not recognized and that you may not be connecting to the site that you intended.
Signed certificates must be created via an outside security service (e.g., VeriSign®, Thawte™, etc.) and then uploaded to the NBB unit to verify the user's identity. In order to use Signed certificates, you must contact an appropriate security service and set up your domain name server to recognize the name that you will assign to the NBB unit (e.g., service.wti.com.) Once a signed certificate has been created and uploaded to the NBB, you will then be able to access command mode without seeing the warning message that is normally displayed for Self Signed certificate access.

Figure 14.1: Web Access Parameters (Text Interface Only)
Saving and Restoring Configuration Parameters 14.1. Creating a Self Signed Certificate
To create a Self Signed certificate, access the Text interface via Telnet or SSH, using a password that permits access to Administrator level commands and then proceed as follows: 1. Type /N and press [Enter] to display the Network Parameters menu.
2. At the Network Parameters menu, type 23 and press [Enter] to display the
Web Access menu (Figure 14.1.) Type 3 and press [Enter] and then follow the
instructions in the resulting submenu to enable HTTPS access. 3. Next, use the Web Access menu to define the following parameters.
Note: When configuring the NBB, make certain to define all of the following
parameters. Although most SSL applications require only the Common Name,
in the case of the NBB all of the following parameters are mandatory.
• 5. Common Name: A domain name, that will be used to identify the NBB unit.
If you will use a Self Signed certificate, then this name can be any name that you choose, and there is no need to set up your domain name server to recognize this name. However, if you will use a Signed certificate, then your domain name server must be set up to recognize this name (e.g., service.wti.com.) • 6. State or Province: The name of the state or province where the NBB unit will
be located (e.g., California.) • 7. Locality: The city or town where the NBB unit will be located (e.g., Irvine.)
• 8. Country: The two character country code for the nation where the NBB will
be located (e.g., US.) • 9. Email Address: An email address, that can be used to contact the person
responsible for the NBB (e.g., [email protected].) • 10. Organizational Name: The name of your company or organization
(e.g., Western Telematic.) • 11. Organizational Unit: The name of your department or division; if necessary,
any random text can be entered in this field (e.g., tech support.) Saving and Restoring Configuration Parameters 4. After you have defined parameters 5 through 11, type 12 and press [Enter] (Create
CSR) to create a Certificate Signing Request. By default, this will overwrite any existing certificate, and create a new Self Signed certificate.
a) The NBB will prompt you to create a password. Key in the desired password (up to 16 characters) and then press [Enter]. When the NBB prompts you to
verify the password, key it again and then press [Enter] once. After a brief
pause, the NBB will return to the Web Access Menu, indicating that the CSR
has been successfully created.
b) When the Web Access Menu is re-displayed, press [Esc] several times until
you exit from the Network Parameters menu and the "Saving Configuration" message is displayed.
5. After the new configuration has been saved, test the Self Signed certificate by accessing the NBB via the Web Interface, using an HTTPS connection. a) Before the connection is established, the NBB should display the warning message described previously. This indicates that the Self Signed certificate has been successfully created and saved.
b) Click on the "Yes" button to proceed. The NBB will prompt you to enter a user name and password. After keying in your password, the main menu should be displayed, indicating that you have successfully accessed command mode.
14.2. Creating a Signed Certificate
To create a Signed certificate, and eliminate the warning message, first set up your domain name server to recognize the Common Name (item 5) that you will assign to the unit. Next, complete steps one through five as described in Section 14.1 and then proceed as follows: 1. Capture the Newly Created Certificate: Type 13 and press [Enter] (View CSR).
The NBB will prompt you to configure your communications (Telnet) program to
receive the certificate. Set up your communications program to receive a binary
file, and then press [Enter] to capture the file and save it. This is the Code Signing
Request that you will send to the outside security service (e.g., VeriSign, Thawte,
etc.) in order to have them sign and activate the certificate.
2. Obtain the Signed Certificate: Send the captured certificate to the outside
security service. Refer to the security service's web page for further instructions. Saving and Restoring Configuration Parameters 3. Upload the Signed Certificate to the NBB: After the "signed" certificate is
returned from the security service, return to the Web Access menu.
a) Access the NBB command mode via the Text Interface using an account that permits Administrator level commands as described previously, then type /N
and press [Enter] to display the Network Parameters menu, and then type 23
and press [Enter] to display the Web Access menu.
b) From the Web Access menu, type 14 and press [Enter] (Import CRT) to
begin the upload process. At the CRT Server Key submenu, type 1 and press
[Enter] to choose "Upload Server Key."
c) Use your communications program to send the binary format Signed Certificate to the NBB unit. When the upload is complete, press [Escape] to
exit from the CRT Server Key submenu.
d) After you exit from the CRT Server Key submenu, press [Escape] several times until you have exited from the Network Parameters menu and the "Saving Configuration" message is displayed.
4. After the configuration has been saved, test the signed certificate by accessing the NBB via the Web Browser Interface, using an HTTPS connection. For example, if
the common name has been defined as "service.companyname111.com", then you
would enter "https://service.companyname111.com" in your web browser's
address field. If the Signed Certificate has been properly created and uploaded, the warning message should no longer be displayed.
14.3. Downloading the Server Private Key
When configuring the NBB's SSL encryption feature (or setting up other security/authentication features), it is recommended to download and save the Server Private Key. To download the Server Private Key, access the Text interface via Telnet or SSH, using a password that permits access to Administrator level commands and then proceed as follows: 1. Type /N and press [Enter] to display the Network Parameters menu.
2. At the Network Parameters menu, type 23 and press [Enter] to display the Web
Access menu (Figure 14.1.) a) To download the Server Private Key from the NBB unit, make certain that SSL parameters have been defined as described in Section 14.1, then type 15 and
press [Enter] and store the resulting key on your hard drive.
b) To upload a previously saved Server Private Key to the NBB unit, make certain that SSL parameters have been defined as described in Section 14.1, then type 16 and press [Enter] and follow the instructions in the resulting submenu.
15. Saving and Restoring Configuration Parameters
Once the NBB is properly configured, parameters can be downloaded and saved as an ASCII text file. Later, if the configuration is accidentally altered, the saved parameters can be uploaded to automatically reconfigure the unit without the need to manually assign each parameter.
Saved parameters can also be uploaded to other identical NBB units, allowing rapid set-up when several identical units will be configured with the same parameters.
The "Save Parameters" procedure can be performed from any terminal emulation program (e.g. HyperTerminal™, TeraTerm, etc.,) that allows downloading of ASCII files.
Note: Configuration parameters can be downloaded and saved via either the
Web Browser Interface or Text Interface. Saved configuration parameters can
only be uploaded to the unit via the Text Interface.
15.1. Sending Parameters to a File
15.1.1. Downloading & Saving Parameters via Text Interface
1. Start your terminal emulation program and access the Text Interface command mode using an account that permits Administrator level commands.
2. When the command prompt appears, type /U and press [Enter]. The NBB will
prompt you to configure your terminal emulation program to receive an ASCII download.
a) Set your terminal emulation program to receive an ASCII download, and the specify a name for a file that will receive the saved parameters (e.g. NBB.PAR).
b) Disable the Line Wrap function for your terminal emulation program. This will prevent command lines from being broken in two during transmission.
3. When the terminal emulation program is ready to receive the file, return to the NBB's Save Parameter File menu, and press [Enter] to proceed. NBB parameters
will be saved on your hard drive in the file specified in Step 2 above.
4. The NBB will send a series of ASCII command lines which specify currently selected parameters. When the download is complete, press [Enter] to return to
the command prompt.
Saving and Restoring Configuration Parameters 15.1.2. Downloading & Saving Parameters via Web Browser Interface
The Web Browser Interface also includes a download function that can be used to save
NBB parameters to an XML format file on your PC or laptop. To save parameters via the
Web Browser Interface, proceed as follows:
• Although NBB parameters can be saved to a file via either the Text Interface or Web Browser Interface, saved parameters can only be restored via the Text Interface. The Restore Parameters function is not available via the Web Browser Interface. • This procedure may differ slightly, depending on the operating system and browser used. In some cases, your system may perform a security scan before proceding with the download. 1. Access the Web Browser Interface command mode using an account that permits Administrator level commands.
1. When the Web Browser Interface appears, click on the "Download Unit Configuration" button on the left hand side of the screen.
2. After a brief pause, your browser may display a prompt asking if you want to open or save the downloaded file. At this point, you can either select the "Save" option to save the parameters file to the download folder on your PC, or select "Save As" to pick a different location and/or filename for the saved parameters file.
15.2. Restoring Saved Parameters
This section describes the procedure for using your terminal emulation program to send saved parameters to the NBB.
Note: The Restore Parameters feature is only available via the Text Interface.
1. Start your terminal emulation program and access the NBB's Text Interface command mode using an account that permits Administrator level commands.
2. Configure your terminal emulation program to upload an ASCII text file.
3. Upload the ASCII text file with the saved NBB parameters. If necessary, key in the file name and directory path.
4. Your terminal emulation program will send the ASCII text file to the NBB. When the terminal program is finished with the upload, make certain to terminate the Upload mode.
Note: If the NBB detects an error in the file, it will respond with the "Invalid
Parameter" message. If an error message is received, carefully check the
contents of the parameters file, correct the problem, and then repeat the Upload
procedure.
5. If the parameter upload is successful, the NBB will send a confirmation message, and then return to the command prompt. Type /S and press [Enter], the Status
Screen will be displayed. Check the Status Screen to make certain the unit has been configured with the saved parameters.
Saving and Restoring Configuration Parameters 15.3. Restoring Previously Saved Parameters
If you make a mistake while configuring the NBB unit, and wish to return to the
previously saved parameters, the Text Interface's "Reboot System" command (/I)
offers the option to reinitialize the NBB unit using previously backed up parameters. This allows you to reset the unit to previously saved parameters, even after you have changed parameters and saved them.
• The NBB will automatically backup saved parameters once a day, shortly after Midnight. This configuration backup file will contain only the most recently saved NBB parameters, and will be overwritten by the next night's daily backup. • When the /I command is invoked, a submenu will be displayed which offers several Reboot options. Options 5 is used to restore the configuration backup file. The date shown next to options 5 indicates the date that you last changed and saved unit parameters. • If the daily automatic configuration backup has been triggered since the configuration error was made, and the previously saved configuration has been overwritten by newer, incorrect parameters, then this function will not be able to restore the previously saved (correct) parameters. To restore the previously saved configuration, proceed as follows: 1. Access command mode via the Text Interface, using a username/password that permits access to Administrator level commands (see Section 5.1.1.) 2. At the NBB command prompt, type /I and press [Enter]. The NBB will display a
submenu that offers several different reboot options.
3. At the submenu, you may choose Item 5 (Reboot & Restore Last Known Working Configuration.) Type 5 and press [Enter].
Note: When invoking the /I command to restore configuration parameters,
Item 5 is recommended.
4. The NBB will reboot and previously saved parameters will be restored.
16. Upgrading NBB Firmware
When new, improved versions of the NBB firmware become available, either the Firmware Upgrade Utility (recommended) or the "Upgrade Firmware" function (Text Interface only) can be used to update the unit. The following Section describes the procedure for updating the NBB unit using the Firmware Upgrade Utility or the Upgrade Firmware function.
16.1. Firmware Upgrade Utility (Recommended)
The preferred method for updating NBB units is via the WTI Firmware Upgrade Utility. The WTI Firmware Upgrade Utility allows you to manage firmware updates for multiple WTI units from a single interface.
A zip file that contains the installation files and other documentation for the WTI Firmware Upgrade Utility can be downloaded from WTI's FTP server, located at: Please refer to the documentation included in the zip file for further instructions.
16.2. The Upgrade Firmware Function (Alternate Method)
The Upgrade Firmware function provides an alternative method for updating the NBB firmware. Updates can be uploaded via FTP or SFTP protocols.
• The FTP/SFTP servers can only be started via the Text Interface.
• All other ports will remain active during the firmware upgrade procedure.
• If the upgrade includes new parameters or features not included in the previous firmware version, these new parameters will be set to their default values. • The upgrade procedure will require approximately 15 minutes. 1. Obtain the update file. Firmware modifications can either be mailed to the customer, or downloaded from WTI. Place the upgrade CDR in your disk drive or copy the file to your hard drive.
2. Access Text Interface command mode via Serial Port, Telnet or SSH client session, using a username/password and port that permit Administrator level commands.
Upgrading VMR/NPS Firmware 3. When the command prompt appears, type /UF and then press [Enter]. The NBB
will display a screen which offers the following options: a) Start FTP/SFTP Servers Only (Do NOT default parameters): To proceed
with the upgrade, while retaining user-defined parameters, type 1 and press
[Enter]. All existing parameter settings will be restored when the upgrade is
complete.
b) Start FTP/SFTP Servers & Default (Keep IP parameters & SSH Keys): To
proceed with the upgrade and default all user-defined parameters except for
the IP Parameters and SSH Keys, type 2 and press [Enter]. When the upgrade
is complete, all parameter settings except the IP Parameters and SSH Keys, will be reset to factory default values.
c) Start FTP/SFTP Servers & Default (Default ALL parameters): To proceed
with the upgrade, and reset parameters to default settings, type 3 and press
[Enter]. When the upgrade is complete, all parameters will be set to
default values.
d) Start FTP/SFTP Servers for Slip Stream Upgrade: This option will upgrade
only the WTI Management Utility, without updating the NBB's operating
firmware. To update the WTI Management Utility only, type 4 and
Note that after any of the above options is selected, the NBB will start the receiving servers and wait for an FTP/SFTP client to make a connection and upload a valid firmware binary image.
4. To proceed with the upgrade, select the desired option. The NBB will display a message that indicates that the unit is waiting for data. Leave the current Telnet/SSH client session connected at this time.
5. Open your FTP/SFTP application and (if you have not already done so,) login to the NBB unit, using a username and password that permit access to Administrator level commands.
6. Transfer the md5 format upgrade file to the NBB.
7. After the file transfer is complete, the NBB will install the upgrade file and then reboot itself and break all port connections. Note that it will take approximately 10 minutes to complete the installation process. The unit will remain accessible until it reboots.
a) Some FTP/SFTP applications may not automatically close when the file transfer is complete. If this is the case, you may close your FTP/SFTP client manually after it indicates that the file has been successfully transferred.
b) When the upgrade process is complete, the NBB will send a message to all currently connected network sessions, indicating that the NBB is going down for a reboot.
Note: Do not power down the NBB unit while it is in the process of installing
the upgrade file. This can damage the unit's operating system.
Upgrading VMR/NPS Firmware 8. If you have accessed the NBB via the Network Port, in order to start the FTP/SFTP servers, the NBB will break the network connection when the system is reinitialized.
• If you initially selected "Start FTP/SFTP Servers and Save Parameters", you may then reestablish a connection with the NBB using your former IP address.
• If you initially selected "Start FTP/SFTP Servers and Default Parameters", you must then login using the NBB's default IP address (Default = 192.168.168.168) or access command mode via Serial Port 1 or 2 or via Modem.
When firmware upgrades are available, WTI will provide the necessary files. At that time, an updated Users Guide or addendum will also be available.
17. Command Reference Guide
17.1. Command Conventions
Most commands described in this section conform to the following conventions: • Text Interface: Commands discussed in this section, can only be invoked via the
Text Interface. These commands cannot be invoked via the Web Browser Interface.
• Slash Character: Most NBB Text Interface commands begin with the Slash
• Apply Command to All Plugs: When an asterisk is entered as the argument of
the /ON (Switch Plugs On), /OFF (Switch Plugs Off) or /BOOT (Reboot Plugs)
commands, the command will be applied to all plugs. For example, to reboot all
allowed plugs, type /BOOT * [Enter].
• Command Queues: If a switching or reboot command is directed to a plug that
is already being switched or rebooted by a previous command, then the new command will be placed into a queue until the plug is ready to receive additional commands. • "Busy" Plugs: If the "Status" column in the Plug Status Screen includes an asterisk,
this means that the plug is currently busy, and is in the process of completing a previously issued command. If a new command is issued to a busy plug, then the new command will placed into a queue to be executed later, when the plug is ready to receive additional commands.
• Plug Name Wild Card: It is not always necessary to enter the entire plug name.
Plug names can be abbreviated in command lines by entering the first character(s)
of the name followed by an asterisk (*). For example, a plug named "SERVER" can
be specified as "S*". Note however, that this command would also be applied to
any other plug name that begins with an "S".
• Suppress Command Confirmation Prompt: When the /ON (Switch Plug
On), /OFF (Switch Plug Off), /BOOT (Reboot Plug) or /DPL (Default All Plugs)
commands are invoked, the ",Y" option can be included to override the Command
Confirmation ("Sure?") prompt. For example, to reboot Plug A4 without displaying
the Sure prompt, type /BOOT A4,Y [Enter].
• Enter Key: Most commands are invoked by pressing [Enter].
• Configuration Menus: To exit from a configuration menu, press [Esc].

For reprint orders, please contact: [email protected] Sexual dysfunction in male schizophrenia: influence of antipsychotic drugs, prolactin and polymorphisms of the dopamine D2 receptor genes Aim: Sexual dysfunction induced by antipsychotic drug treatment is under investigated and under reported. This study aimed to determine the influence of genetic polymorphisms in the D2 dopamine receptor (DRD2) and endothelial nitric oxide synthase (eNOS) genes, and the possible role of blood prolactin concentrations on sexual function in schizophrenic patients. Materials & methods: Male remitted schizophrenic patients (n = 100), who were living with a sexual partner and receiving antipsychotic drug monotherapy for at least 6 months, were assessed for sexual and erectile dysfunction using the Arizona Sexual Experience Scale and the five-item version of the International Index of Erectile Function. Blood samples were taken for plasma prolactin determination and genotyped for four polymorphisms: DRD2 (-141C Ins/Del and Taq1A) and eNOS gene (G894T and T-786C). Results: The -141C Ins/Del, but not Taq1A, polymorphism of the DRD2 gene was significantly associated with sexual dysfunction with the del allele being less frequent in sexual dysfunction subjects. Neither of the eNOS polymorphisms, G894T or T-786C, was significantly associated with sexual or erectile dysfunction. Prolactin concentrations were significantly higher in patients with erectile dysfunction but did not reach significance in those with sexual dysfunction. Prolactin was also reduced in -141C Del allele carriers. The frequency and severity of sexual dysfunction in the patients receiving typical antipsychotics was significantly greater than those receiving risperidone or clozapine, while prolactin concentrations were significantly higher in subjects receiving risperidone compared with those receiving clozapine or typical antipsychotics. Conclusion: This is the first evidence indicating that antipsychotic drug treatment in men is associated with a variant in the DRD2 gene in which the -141C Del allele might be a protective factor. While this may, in part, be mediated by effects on prolactin, other factors are likely to contribute to the greater sexual dysfunction in patients receiving typical antipsychotics.Original submitted 25 January 2011; Revision submitted 21 March 2011
