Installation Instructions
Secure Racking
If Secure Racked units are installed in a closed or multi-unit rack assembly, they may
require further evaluation by Certification Agencies. The following items must be
considered.
1. The ambient within the rack may be greater than room ambient. Installation
should be such that the amount of air flow required for safe operation is not
compromised. The maximum temperature for the equipment in this environment is
55°C. Consideration should be given to the maximum rated ambient.
2. Installation should be such that a hazardous stability condition is not achieved due
to uneven loading.
3. Side vents are used to dissipate heat generated within the unit. When mounting
the unit in an equipment rack, make certain to allow adequate clearance for
venting.
Input Supply
Check nameplate ratings to assure there is no overloading of supply circuits that could
have an effect on overcurrent protection and supply wiring.
Grounding
Reliable earthing of this equipment must be maintained. Particular attention should
be given to supply connections when connecting to power strips, rather than direct
connections to the branch circuit.
No Serviceable Parts Inside; Authorized Service Personnel Only
Do not attempt to repair or service this device yourself. Internal components must be
serviced by authorized personnel only.

and contact qualified service personnel:
1. If the power cord becomes frayed or damaged.
2. If liquid has been spilled into the device or if the device has been exposed to rain
or water.
Up to Four Power Supply Cables
Note that some VMR/NPS series units feature two separate power inlets and a separate
power supply cable for each power inlet.
In addition, some VMR-HD4D-8 series units feature four separate power inlets and a
separate power supply cable for each power inlet. Make certain to disconnect all power
supply cables from their power source before attempting to service or remove the unit.
Detached 15-Amp “Starter” Cable(s)
If the VMR or NPS unit includes a detached, 125 VAC, 15 Amp “Starter” Cable(s,) this
allows you to connect the VMR or NPS to power for bench testing and initial start up and
is adequate for applications that only require 15 Amps. For 20-Amp power switching
applications, please refer to the WTI Power Cable guide supplied with the unit, or use
appropriate 20-Amp cables.
Units with Attached Power Supply Cable(s)
For units with fixed Power Cords the socket-outlet shall be installed near the equipment
and shall be easily accessible.

1. Introduction
WTI’s VMR series Managed Power Controllers and NPS 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. Both VMR and NPS
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, VMR 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. (Note that NPS
series models do not support current and power metering functions.)
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.
Both the VMR and NPS provide 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.
The VMR and NPS 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 (VMR Series Only):
VMR series units can measure and report current and power consumption trends. If the
VMR detects that user defined thresholds for current consumption have been exceeded
the unit can provide prompt notification to network administrators and IT personnel.
The VMR 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.

5. Basic Operation
5.1. Communicating with the VMR/NPS Unit
In order to control and configure the VMR/NPS, you must first connect to the unit,
and access command mode. Note that, the VMR/NPS offers two separate command
interfaces; the Web Browser Interface and the Text Interface.
In addition, the VMR/NPS also offers three different methods for accessing command
mode; via network, via external modem, or via local console. The Web Browser
interface is only available via network, and the Text Interface is available via network
(SSH or Telnet), modem or local PC.
5.1.1. The Text Interface
The Text Interface consists of a series of simple ASCII text menus, which allow you to set
options and define parameters by entering the number for the desired option using your
keyboard, and then typing in the value for that option.
Since the Web Browser Interface and Telnet accessibility are both disabled in the default
state, you will need to use the Text Interface to contact the VMR/NPS via Local PC or
SSH connection when setting up the unit for the first time. After you have accessed
command mode using the Text Interface, you can then enable Web Access and Telnet
Access, if desired, in order to allow future communication with the unit via Web Browser
or Telnet. You will not be able to contact the unit via Web Browser or Telnet until you
have enabled these options.
Once Telnet Access is enabled, you will then be able to use the Text Interface to
communicate with the VMR/NPS via local PC, Telnet or SSH connection. You can also
use the Text Interface to access command mode via an external modem installed at the
VMR/NPS serial Setup Port.
In order to use the Text Interface, your installation must include:
• Access via Network: The VMR/NPS must be connected to your TCP/IP Network,
and your PC must include a communications program (such as TeraTerm or PuTTy.)
• Access via Modem: An external modem must be installed at the VMR/NPS
RS232 Setup Port (see Section 4.3.2), a phone line must be connected to the
external modem, and the Setup Port must be configured for Modem Mode. In
addition, your PC must include a communications program.
• Access via Local PC: Your PC must be physically connected to the VMR/NPS
RS232 Setup Port as described in Section 4.3.1, the VMR/NPS Setup Port must
be configured for Normal Mode, and your PC must include a communications
program.

These commands can be used to switch or reboot the VMR/NPS Series unit’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.
Notes:
• 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.
• If a switching or reboot command is directed to a plug that is already busy
completing a previous command, then the new command will be placed in a
queue until the plug is ready to receive additional commands.
• Administrator and SuperUser level accounts can use the Port and Plug Status
Screen to display information for all serial ports and switched outlets.
• User and ViewOnly level accounts can only use the Port and Plug Status
Screen to display information for serial ports and outlets that are allowed by
the account.
• Administrator or SuperUser level accounts can direct switching and reboot
commands to all plugs.
• User Level accounts can only direct switching and reboot commands to the
plugs that are specifically allowed by that account.
• The Status Screen will be displayed after switching and reboot commands
are successfully completed.
• When switching and reboot operations are initiated, Boot/Sequence Delay
times and user-defined Plug Priority values will be applied as described in
Section 6.6.
• Text Interface commands are not case sensitive. When used in On/Off/
Reboot command lines, plug names and plug group names are also not
case sensitive.
When switching and reboot commands are executed, the VMR/NPS Series unit 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 Port
and Plug Status Screen.
To Switch Plugs, or initiate a Reboot Cycle, proceed as follows:
1. Switch Plug(s) On: To power-on a plug or Plug Group, type /ON n and press
[Enter]. Where "n" is the number or name of the desired plug or Plug Group. For
example:

be applied to all plugs.
• When you have accessed command mode using an account that only
permits User level command access, the Default command will only be
applied to the plugs specifically allowed by that account.
• Switching commands are not available in ViewOnly mode.
5. Suppress Command Confirmation Prompt: To execute a Boot/On/Off
command without displaying the "Sure?" prompt, you can either disable command
confirmation via the System Parameters Menu, or include the ",Y" option at the end
of the command line. For example:
/ON ROUTER,Y or /BOOT 2,Y
5-8
Basic Operation
5.3.2.1. 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.
Note: When switching and reboot operations are initiated, Boot/Sequence
Delay times and user-defined Plug Priority values will be applied as described in
Section 6.6.
1. Switch Several Plugs: To apply a command to several plugs, enter the numbers
or names for the plugs, separated by a "plus sign" (+) or a comma (,). For example
to switch plugs 1, 3, and 4 Off, enter either of the following commands:
/OFF 1+3+4 [Enter]
or
/OFF 1,3,4 [Enter]
Note: When the "+" or "," are used, do not enter 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
number for the plugs that mark the beginning and end of the series, separated by a
colon. For example to switch On plugs 1 through 3, enter the following:
/ON 1:3 [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]
Note: When this command is invoked by an account that permits only User
level command access, it will be applied only to the plugs that are allowed for
that account.
5-9
Basic Operation
5.4. The Automated Mode
The Automated Mode allows the VMR/NPS to execute switching and reboot commands,
without displaying menus or generating response messages. Automated Mode is
designed to allow the VMR/NPS 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 VMR/NPS 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 On / Off / Boot
commands.
Notes:
• When Automated Mode is enabled, all VMR/NPS 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 VMR/NPS configuration menus, it is recommended to enable and
configure the IP Tables Function as described in Section 6.8.2.
To enable/disable Automated Mode, access the System Parameters menu (see
Section 6.2,) then set the "Automated Mode" option to "On". When Automated Mode is
enabled, VMR/NPS 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 VMR/NPS 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.
5-10
Basic Operation
5.5. Manual Operation
In addition to the command driven functions available via the Web Browser Interface
and Text Interface, some VMR/NPS functions can also be controlled manually. For a
summary of front panel control functions, please refer to Section 2.11.
5.6. Logging Out of Command Mode
When you have finished communicating with the VMR/NPS, 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 you disconnect using the LogOut link or /X command, this ensures that the
VMR/NPS has completely exited from command mode, and is not waiting for the
inactivity timeout period to elapse before allowing additional connections.
5.7. Emergency Shut Off Function
VMR/NPS Series units also include an Emergency Shut Off function, that can be used to
immediately shut off all power outlets on an VMR/NPS Series unit in case of emergency.

characters long) for the primary NTP server. (Default = undefined.)
Notes:
• In order to use domain names for web addresses, DNS parameters must first
be defined as described in Section 6.8.4.
• 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 VMR/NPS will display a prompt that instructs the user to
select IPv4 or IPv6 protocol.
• The VMR/NPS 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.)
Notes:
• In order to use domain names for web addresses, DNS parameters must first
be defined as described in Section 6.8.4.
• 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 VMR/NPS will display a prompt that instructs the user to
select IPv4 or IPv6 protocol.
• The VMR/NPS 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
VMR/NPS will retry the connection four times. If neither the primary nor secondary
NTP server responds, the VMR/NPS 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.
Notes:
• 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.

Configuration Options
6.2.2. 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 VMR/
NPS 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 VMR/NPS 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 VMR/NPS 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 VMR/NPS 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 VMR/NPS logical network ports and communication
protocols.
Notes:
• When the Serial Port Invalid Access Lockout Alarm has been enabled as
described in Section 8.6, the VMR/NPS 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.)
6-7
Configuration Options
• 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 VMR/NPS 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 VMR/NPS 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.)
• 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 VMR/NPS
for the defined SSH Lockout Duration period. (Default = 2 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 VMR/NPS 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 VMR/NPS 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
VMR/NPS for the defined Telnet Lockout Duration period.
(Default = 2 Seconds.)
6-8
Configuration Options
• 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 VMR/NPS 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 VMR/NPS 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.)
• 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 VMR/NPS
for the defined Telnet Lockout Duration period. (Default = 2 Seconds.)

6.2.4. 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 VMR/NPS 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 6.4.
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

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 reenter 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.

6.2.5. Power Source Configuration (VMR Only)
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 VMR. Real Power is determined by the following equation:
Real Power =
(Voltage * Amps) * Power Factor
Power Efficiency
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.
Notes:
• Current and Power Metering functions are not available on NPS units.
• In the Text Interface, power source configuration parameters are defined via

Mode is required, it is recommended to use the IP Tables feature (Section 6.3.2)
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 for VMR units = VMR; Default for NPS units = NPS.)
6-15
Configuration Options
• IPS Mode: This parameter sets up the VMR/NPS 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 VMR/NPS
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
VMR/NPS 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 VMR/NPS will return to the status where no username or
password prompts are displayed upon login to command mode.
• Emergency Shutoff: Enables/disables the Emergency Shutoff Feature. The
Emergency Shutoff function can be used to immediately shut off all specified power
outlets on a VMR/NPS Series unit in case of emergency. For more information,
please refer to Section 5.7. (Default = Off)
• Emergency Shutoff Auto Recovery: Enables/Disables the Emergency Shutoff
Auto Recovery feature. When enabled, following an Emergency Shutoff, all plugs
will return to the On/Off status that was selected prior to the Emergency Shutoff.
(Default = Off)
• Single Plug Boot Delay Enable: When this parameter is enabled and reboot cycle
is initiated, the VMR/NPS will pause for the currently defined Boot/Sequence Delay
value before executing the next reboot command. Note that the Boot/Sequence
Delay value is defined via the Plug Parameters menu, as described in Section 6.7.
(Default = Off.)
• U-Boot Plugs Enable: When enabled, after a power interruption, the VMR/NPS
will switch on all power outlets before the VMR/NPS operating system has finished
loading. This allows power to be reapplied to connected devices such as servers
and routers as quickly as possible after a power interruption. (Default = Off)
• Voltage Loss Delay Options: Determines how VMR/NPS Series Units with Dual
Power Inlets will react when power to one inlet is lost. The Voltage Loss Delay
Options allow the unit to automatically turn off outlets and delay the Lost Voltage
Alarm when power to one inlet is lost.
• Turn Plugs Off Enable: When enabled, after power to one inlet is lost, the unit
will wait for the defined Voltage Loss Delay period and then switch Off all outlets
on the branch that was supported by the inlet that has lost power. (Default = Off)
• Voltage Loss Delay: Determines how long the unit will pause before generating
a Lost Voltage Alarm and switching off the outlets after power to one of the inlets
is lost. (Default = 12 Seconds)
6-16
Configuration Options
• Reverse DNS: Determines the manner in which ARP requests are handled. When
enabled (On,) the unit will check an external DNS in order to resolve domain
names. When disabled (Off,) the unit will not check an external DNS when
resolving domain names. (Default = On)
• Port 1 Mode Override: In order to ensure local access to VMR/NPS command
functions, normally Serial Port 1 can only be configured as a Passive Mode Port or
Any-to-Any Mode Port. When the Port 1 Mode Override option is enabled, Serial
Port 1 can be configured as a Buffer Mode Port, Modem Mode Port or Modem PPP
Mode Port. (Default = Off)
Note: Configuring Serial Port 1 as a Buffer Mode Port can disable local access
to VMR/NPS command functions via serial port.
• Keep Alive: In cases where Linux regularly times out and disrupts network
communication with the unit, this parameter can be used to keep the network
connection active. (Default = 7,200 Seconds)
6.2.6.1. Automated Mode
The Automated Mode allows the VMR/NPS to execute switching and reboot commands,
without displaying menus or generating response messages. Automated Mode is
designed to allow the VMR/NPS 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 VMR/NPS 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.
Notes:
• 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 6.8.2.
6-17
Configuration Options
To enable/disable the Automated Mode, go to the System Parameters menu (see
Section 6.2,) and then set the “Automated Mode” option to “On”. When Automated
Mode is enabled, VMR/NPS 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.
6-18
Configuration Options
6.3. 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 VMR/NPS 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.
6.3.1. Command Access Levels
In order to restrict access to important command functions, the VMR/NPS allows you to
set the command access level for each user account. The VMR/NPS 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 VMR/NPS 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
VMR/NPS 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 access for all four access levels.
In the default state, the VMR/NPS includes one predefined account that provides access
to Administrator commands and allows control of all VMR/NPS switched power outlets.
The default username for this account is "super" (lowercase, no quotation marks), and
the password for the account is also "super".
Notes:
• 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 VMR/NPS is reset to default parameters, all user accounts will be
cleared, and the default "super" account will be restored.
6-19
Configuration Options
6.3.2. Granting 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.
6.3.3. Granting Port Access
The Port Access parameter is used to grant or deny access to the VMR/NPS 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 which ports the account will be allowed
to access, 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.

Administrator Access. If you do not retain at least one account with
Administrator Access, you will not be able to invoke Administrator level
commands.
6-24
Configuration Options
6.5. 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
VMR/NPS Plug Group as described in Section 6.5.1.
• Add Plug Group to Directory: Creates new Plug Groups, and allows you to assign
plug access rights to each group as described in Section 6.5.2.
• Modify Plug Group Directory: This option is used to edit or change plug access
rights for each Plug Group, as described in Section 6.5.3.
• Delete Plug Group from Directory: Clears Plug Groups that are no longer
needed, as described in Section 6.5.4.
6.5.1. 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.
6-25
Configuration Options
6.5.2. 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.)
Notes:
• 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.

Configuration Options
6.6. Defining Plug Parameters
The Plug Parameters Menu is used to define Plug Names, boot/sequence delay times
and Power Up Default values for each VMR/NPS 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 VMR/
NPS 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 VMR/NPS 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 VMR/NPS will pause for
ten seconds before proceeding to the next plug.

"On" Sequence Delay: When two or more plugs are switched On, the
VMR/NPS 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
VMR/NPS will automatically switch each plug On or Off as specified by the PowerUp Default. (Default = On).
Note:
• 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.
• The Default command is not available to ViewOnly level accounts.
• Boot Priority: When commands are applied to two or more plugs, the Boot
Priority parameter determines the order in which the 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. When you assign a boot priority to any given plug, then all subsequent plugs
will have their priority lowered by one. For more information on the Boot Priority
parameter, please refer to Section 6.6.1. (Default = All plugs prioritized according
to Plug Number)
6-27
Configuration Options
6.6.1. The Boot Priority Parameter
Normally, when an "On" or "Reboot" command is invoked, the VMR/NPS 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 VMR/NPS 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 VMR/NPS (and re-define plug parameters) to ensure that they
are switched on in the desired order.
Notes:
• 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.
6.6.1.1. Example 1: Change Plug A3 to Priority 1
In the Example shown in Figure 6.1, 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.

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.

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.)

Configuration Options
The Network Configuration Menus:
The Network Configuration menus allow you to define both IPv4 parameters and IPv6
parameters for the Ethernet Port. Although there are slight differences in the manner
in which the Web Interface and Text Interface Network are organized, both interfaces
provide access to essentially the same set of network parameters (with a few noted
exceptions.)
Since the network configuration menus must allow definition of network parameters for
two different IP protocols, parameters have been divided into two different submenus.
These submenus are accessed via the Network Selection menu.
To access the Network Selection menu, proceed as follows:
• Text Interface:
Type /N* and then press [Enter] to display the Network Selection menu. At the
Network Selection menu, key in the number for the desired protocol and then
press [Enter].
• Web Browser Interface: Click on the Network Configuration link on the left hand
side of the screen to display the Network Selection menu. When the Network
Selection menu appears, click on the desired protocol. Alternately, the Network
Configuration link's flyout menus can also be used to select the desired protocol.
The Network Selection menu offers access to two Network Configuration submenus:
• Port Eth0, IPv4 Protocol (Plus Shared Parameters)
• Port Eth0, IPv6 Protocol
Note that the VMR/NPS's Network Configuration Menus are used to define parameters
that are shared by all VMR/NPS both IP protocols, plus parameters that are specific to
only one IP protocol. Since the majority of these shared parameters are concentrated in
the Eth0/IPv4 submenu, it is recommended that when defining network parameters, to
first define the parameters found in the Shared (Eth0, IPv4,) submenu, and then proceed
to the submenu for IPv6 protocol.

been selected for Raw Socket Acess, in order to establish a Raw Socket
connection to the VMR/NPS's Network Port, then on a UNIX system, the
connection command would be: $ telnet 1.2.3.4 3001 [Enter].
6-41
Configuration Options
6.8.2. IP Tables
The IP Tables allow the VMR/NPS to restrict unauthorized IPv4 or IPv6 format IP
addresses from establishing inbound connections to the unit. If you wish to restrict
access to the VMR/NPS unit, you can employ the IP Tables menu to define a firewall
which determines which IP addresses will be allowed to access the VMR/NPS command
mode and which IP addresses will be denied. To define the firewall, proceed as follows:
1. Use the Text Interface or Web Browser interface to access the IP Tables menu as
described in Section 6.8.
2. When the IP Tables menu is displayed, use Linux syntax to determine which IP
address(es) will be allowed access and which IP address(es) will be denied. In
most cases, the IP Tables should allow access to administrators and deny access to
everybody else.
6.8.3. Static Route
The Static Route menu allows you to define Linux routing commands that will be
automatically executed each time that a user accesses command mode via the
corresponding Network Port or optional Cellular Modem Port.
6.8.4. DNS Services
The DNS option is used to define DNS and DDNS parameters. In the Network
Configuration menu, the DNS option can be used to access either the DNS Parameters
menu or the DDNS parameters menu.
6.8.4.1. DNS Parameters
The DNS Parameters 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.wti.com), and translates them into
IP addresses. 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.

Configuration Options
6.8.7. LDAP Parameters
The VMR/NPS 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 VMR/NPS unit, and existing
users can also be removed without the need to delete the account from each VMR/NPS
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 VMR/NPS 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
VMR/NPS command mode to configure LDAP settings and define port access rights
and command access rights for each group specified at the LDAP server.
Notes:
• Plug access rights are not defined at the LDAP server. They are defined via
the LDAP Group configuration menu on each VMR/NPS unit and are specific
to that VMR/NPS unit alone.
• When LDAP is enabled, LDAP authentication will supersede any passwords
and access rights that have been defined via the VMR/NPS user directory.
• If no LDAP groups are defined on a given VMR/NPS 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 VMR/NPS unit.

6.9. 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
VMR/NPS 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 VMR/NPS 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 VMR/NPS will revert to the
previously saved configuration after you exit from command mode.
6.9.1. Restore Configuration
If you make a mistake while configuring the VMR/NPS 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.
Notes:
• The VMR/NPS will automatically backup saved parameters once a day,
shortly after Midnight. This configuration backup file will contain only the
most recently saved VMR/NPS 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 VMR/NPS command prompt, type /I and press [Enter]. The VMR/NPS 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 VMR/NPS will reboot and previously saved parameters will be restored.
6-57
7. Reboot Options
In addition to performing reboot cycles in response to commands, the VMR/NPS 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 VMR/
NPS will Ping a user selected IP address at regular intervals. If the IP address does
not respond to the Ping command, the VMR/NPS 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 VMR/NPS 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.

8. Alarm Configuration
When properly configured, VMR and NPS units can monitor rack temperature, ping
command response and other factors at network installation sites. In addition to the
monitoring abilities listed above, VMR series units can also measure and record current,
power and voltage conditions. Note however that NPS units do not support current
consumption, power and voltage monitoring functions.
If user defined trigger levels for temperature are exceeded, the VMR/NPS 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 VMR/NPS can then switch outlets back on again. The VMR (but
not the NPS) can also perform load shedding when current consumption rises above
user-defined threshold values. When any of the user-defined alarms are triggered,
the VMR/NPS 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 VMR/NPS to send alarm
messages when critical situations are detected. For instructions regarding configuration
of the Log function, please refer to Section 6.2.3.
Notes:

8.1. The Over Current Alarms (VMR Only)
The Over Current Alarms are designed to inform you when current consumption
reaches or exceeds user-defined levels. Depending on the specific VMR model, VMR
units can have up to four Over Current Alarms (two sets of two alarms):
•
•
•
•
The Over Current Line (Initial) Alarm
The Over Current Line (Critical) Alarm
The Over Current Branch (Initial) Alarm
The Over Current Branch (Critical) Alarm
Notes:
• Current and Power Monitoring features are not available on NPS units.
• The Line Alarms are not available on some VMR models.
• The parameters that are defined via the Over Current (Initial and Critical)
Alarm Configuration menus will be applied to both Over Current Line Alarms
and Over Current Branch Alarms.
• The VMR does not include separate configuration menus for the Line and
Branch Overcurrent Alarms. Parameters that are defined via the Over Current
Alarm configuration menus will be applied to both Branch and Line (if
present) Alarms.
The Line alarms monitor the load on the input line, and are only available on single input
units, whereas the Branch alarms monitor the load on each branch circuit breaker.
The Initial alarms are used to provide notification when the level of current consumption
reaches a point where you might want to investigate it, whereas the Critical alarms can
provide notification when the level of current consumption approaches the maximum
allowed level. The trigger levels for the Initial alarms are generally set lower than the
trigger levels for the Critical alarms.
If the user-defined trigger levels for current load are exceeded, the VMR can
automatically shut off power to non-essential devices ("Load Shedding") in order to
decrease current load. After Load Shedding has taken place, the VMR 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 8.1.1.
The Load Shedding feature can be configured to react in one manner when an Over
Current Line Alarm is triggered, and in a different manner when an Over Current Branch
Alarm is triggered. For example, Load Shedding may be configured in such a way that
when the Line Alarm is triggered, plugs A1 and B1 are switched Off, but when a Branch
Alarm is triggered, plugs A1 and A2 are switched Off.
Notes:
• In order for the VMR to provide alarm notification via Email, communication
parameters must first be defined as described in Section 6.8.10.
• In order for the VMR to provide alarm notification via Syslog Message, Syslog
parameters must first be defined and Syslog Messages must be enabled as
described in Section 6.8 and Section 11.
• In order for the VMR to provide alarm notification via SNMP Trap, SNMP
parameters must first be defined, and SNMP Traps must be enabled as
described in Section 6.8.6 and Section 12.
8-2
Alarm Configuration
To configure the Over Current Alarms, access the VMR 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 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 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.)
Notes:
• 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 VMR/NPS 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 VMR/NPS alarms will also be enabled.
• Alarm Set Threshold: The trigger level for this alarm. When current load exceeds
the Alarm Set Threshold, the VMR 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 and is applied to both Over Current Branch Alarm and Over
Current Line Alarm (if present.) (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 and is applied to both Over Current Branch Alarm and Over Current Line
Alarm (if present.) (Defaults: Initial Alarms = 70%; Critical Alarms = 80%.)
• Resend Delay: Determines how long the VMR 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 VMR will send additional
notification when the situation that caused the alarm has been corrected. For
example, when Notify Upon Clear is enabled, the VMR 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 6.8.10) 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.
8-3
Alarm Configuration
• 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 VMR 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 VMR can also return these userselected 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 8.1.1.
8.1.1. 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 VMR 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 VMR can also automatically "undo" the effects of the Load Shedding feature when
current load again falls to a user-defined non-critical level.
The VMR also allows you to define separate Load Shedding/Recovery actions for an
Over Current Branch Alarm and an Over Current Line Alarm. For example, if the Line
Alarm is triggered, Load Shedding can switch Off Plugs A1 and B1, yet when the Branch
"A" Alarm is triggered, the VMR can switch Off Plugs A1 and A2.
Together, the Load Shedding and Auto Recovery features allow the VMR 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:
Notes:
• Current and Power Monitoring features are not available on NPS units.
• The Line Alarms are not available on some VMR models.
• The Load Shedding Configuration Menus for all 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 "Branch"
parameters are found in the Over Current Alarm configuration menus.
• The "Unit to Configure," "Branch A," "Branch B" and "Line" parameters are
used to determine which unit or branch the Load Shedding functions will be
applied to.
8-4
Alarm Configuration
• Line Input A: Defines the Load Shedding actions that will be executed when an
Over Current Branch Alarm is triggered at Line Input "A".
• Line Input B: Defines the Load Shedding actions that will be executed when an
Over Current Branch Alarm is triggered at Line Input "B".
• Fuse A1-A4: Defines the Load Shedding actions that will be executed when an
Over Current Branch Alarm is triggered at Fuses A1 through A4.
• Fuse B1-B4: Defines the Load Shedding actions that will be executed when an
Over Current Branch Alarm is triggered at Fuses B1 through B4.
After selecting the branch or line, use the following parameters to configure Load
Shedding functions for the desired branch or line.
• Enable: Enables/Disables Load Shedding for the corresponding alarm. When
enabled, the VMR 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 userdefined 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
branch or line. When both Load Shedding and Auto Recovery are enabled, the
VMR will return plugs to their former On/Off state after current load falls below the
Alarm Clear Threshold value. This allows the VMR 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 6.5) before
they will be displayed in the Load Shedding menu's Plug Group Access
submenu.
After setting parameters for a given branch or line, you may also define additional
parameters for other branches or lines (if present.) To set Load Shedding parameters
for other branches or lines, return to the Alarm Configuration menu and then repeat the
procedure described in Section 8.1.1.

Alarm Configuration
8.2. 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 VMR/NPS 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.
Notes:
• In order for the unit to provide alarm notification via Email, communication
parameters must first be defined as described in Section 6.8.10.
• 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 6.8 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 6.8.6 and Section 12.
To configure the Over Temperature Alarms, access the VMR/NPS 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.)
Note:
• 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 VMR/NPS alarms. For example, if
the Over Temperature Alarm's Trigger Enable parameter is set to "On (Copy to
All Triggers), then all other VMR/NPS alarms will also be enabled.
8-6
Alarm Configuration
• Alarm Set Threshold: The trigger level for this alarm. When temperature exceeds
the Alarm Set Threshold, the VMR/NPS can send an alarm (if enabled) and/or begin
Load Shedding (if enabled.) For more information on Load Shedding for the Over
Temperature Alarm, please refer to Section 8.2.1. (Initial Threshold: Default =
110°F or 43°C, Critical Threshold: Default = 120°F or 49°C.)
Note: The Alarm Set Threshold value must be greater than the Alarm Clear
Threshold value. The VMR/NPS will not allow you to define an Alarm Clear
Threshold value that is higher than the Alarm Set Threshold.
• Alarm Clear Threshold: Determines how low the temperature must drop in order
for the Alarm condition to be cancelled and for Load Shedding (if enabled) to
occur. For more information on Load Shedding for the Over Temperature Alarm,
please refer to Section 8.2.1. (Initial Threshold: Default = 100°F or 38°C, Critical
Threshold: Default = 110°F or 43°C.)
Note: The System Parameters menu is used to set the temperature format for
the VMR/NPS unit to either Fahrenheit or Celsius as described in Section 6.2.
• Resend Delay: Determines how long the VMR/NPS will wait to resend an email
message generated by this alarm, when the initial attempt to send notification was
unsuccessful. (Default = 60 Minutes.)
• Notify Upon Clear: When this item is enabled, the VMR/NPS will send additional
notification when the situation that caused the alarm has been corrected. For
example, when Notify Upon Clear is enabled, the VMR/NPS will send initial
notification when it detects that the temperature has exceeded the trigger value,
and then send a second notification when it determines that the temperature 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 6.8.10,) 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 defined 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 this alarm. (Default = "Alarm:
Over Temperature (Initial)" or "Alarm: Over Temperature (Critical)".)
• Load Shedding: Provides access to a submenu, which is used to configure and
enable the Load Shedding feature for the Over Temperature alarms. When Load
Shedding is enabled and properly configured, the VMR/NPS will switch specific,
user-selected plugs On or Off whenever the temperature exceeds the Alarm Set
Threshold value. If the Auto Recovery feature is enabled, the VMR/NPS can
also return these user-selected plugs to their prior status, when the temperature
falls below the Alarm Clear Threshold value. For more information on the Load
Shedding Feature and Auto Recovery, please refer to Section 8.2.1.

Alarm Configuration
8.2.1. 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 VMR/NPS 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 VMR/NPS 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

Section 6.2.2) can lock the serial SetUp Port whenever the unit detects that a userdefined threshold for invalid access attempts at the SetUp Port is exceeded. When a
serial port lockout occurs, the unit can provide notification via Email, Syslog Message or
SNMP Trap.
Notes:
• Note that Serial Port Invalid Access Lockout Alarm is only intended to provide
notification when the Invalid Access Lockout feature has locked the serial
SetUp Port. To apply the Invalid Access Lockout feature to the Network Port,
please refer to Section 6.2.2.
• In order for this alarm to function, Invalid Access Lockout parameters
for the serial port must first be configured and enabled as described in
Section 6.2.2.
• If desired, the VMR/NPS can be configured to count Invalid Access attempts
at the serial SetUp port, and provide notification when the counter exceeds
a user defined trigger level, without actually locking the port in question. To
do this, enable the Invalid Access Lockout Alarm as described here, but
when you configure Invalid Access Lockout parameters as described in
Section 6.2.2, set the Lockout Attempts and Lockout Duration as you would
normally, and then set the "Lockout Enable" parameter to "Off."

Alarm Configuration
8.8. The Plug Current Alarm (VMR Only)
The Plug Current Alarm allows you to monitor current consumption at each of the VMR's
switched outlets and generate an alarm when current exceeds a user-defined "High"
threshold or falls below a user-defined "Low" threshold. The Plug Current Alarm can
also be applied to user-defined Plug Groups in order to generate an alarm when total
current consumption for the given Plug Group rises too high or falls too low.
Note: Current and Power Monitoring features are not available on NPS units.
If desired, the Plug Current Alarm can also be configured to automatically shut off
individual plugs or user-defined Plug Groups, whenever current consumption rises
above a user-defined threshold value.
To configure the Plug Current Alarm, access the VMR command mode using a
password that permits Administrator Level commands and then use the Alarm
Configuration menu to select the desired alarm feature. The Plug Current Alarm allows
the following parameters to be defined:
• Trigger Enable: Enables/Disables the trigger for this alarm. When disabled, this
alarm will be suppressed. (Default = On.)
Note:
• 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 VMR/NPS alarms. For example,
if the Plug Current Alarm's Trigger Enable parameter is set to "On (Copy to All
Triggers), then all other VMR/NPS alarms will also be enabled.
• Plug Hysteresis: This parameter can be used to prevent the Plug Current
Alarm from generating excessive "Alarm" and "Clear" messages when current
consumption fluctuates back and forth across the trigger value. Basically, the Plug
Hysteresis parameter allows you to define a margin at both the Low Threshold and
High Threshold that the current level must cross in order to clear an alarm.
(Default = 0.5 Amps)
Plug Hysteresis Example: Assume that the Low Threshold for Outlet A1 is set at 5
Amps, the High Threshold is set at 12 Amps and the Plug Hysteresis value is set at
1 Amp. When the current goes high or low, the VMR will respond as follows:
• Low Alarm: If the current drops below 5 Amps, the VMR will generate an Alarm. The Alarm will not be cleared until the current rises above 6 Amps
(5 Amp Low Threshold + 1 Amp Hysteresis Value = 6 Amps.)
• High Alarm: If the current rises above 12 Amps, the VMR will generate an Alarm. The Alarm will not be cleared until the current drops below 11 Amps.
(12 Amp High Threshold - 1 Amp Hysteresis Value = 11 Amps.)
8-17
Alarm Configuration
• Plug Thresholds: Defines current consumption level(s) that will trigger alarm(s) at
each switched outlet. The Plug Thresholds can be configured to trigger an alarm
when current consumption rises above a user-defined "High" value and/or when
current consumption falls below a user-defined "Low" value. This allows you to
define a "normal" current range for each outlet, allowing the Plug Current Alarm to
be triggered whenever current consumption strays outside of this range.
(Default = undefined.)
• Plug Group Thresholds: Defines current consumption level(s) that will trigger
alarm(s) for each user-defined Plug Group. The Plug Group Thresholds can be
configured to trigger an alarm when total current consumption for a given Plug
Group rises above a user-defined "High" value and/or when current consumption
falls below a user-defined "Low" value. This allows you to define a "normal" current
range for each Plug Group, allowing the Plug Current Alarm to be triggered
whenever total current consumption for the Plug Group strays outside of this range.
(Default = undefined.)
Note: In order to define Plug Group Thresholds, you must first define at least
one Plug Group as described in Section 6.5.
• Plug "Off" Low Alarm: Allows you to configure the "Low" current alarm to suppress
triggering when an outlet is purposely switched Off. When this feature is "On", the
VMR will generate a Low alarm whenever current drops below the Low threshold
value, even if the current drop is due to an outlet being purposely switched Off.
When this feature is "Off", the VMR will not generate a Low alarm due to a current
drop caused by an outlet being switched Off. (Default = On)
Notes:
• The Plug "Off" Low Alarm feature will also be applied to Plug Groups. • When the Plug "Off" Low Alarm feature is enabled (On), the VMR will always
generate a Low current alarm when current drops below the Low threshold
value, even when the current drop was caused by one or more outlets in the
Plug Group being purposely switched Off.
• When the Plug "Off" Low Alarm feature is disabled (Off), the VMR will not
generate a Low current Alarm when a current drop is caused by all outlets in
the Plug Group being purposely switched Off. • Resend Delay: Determines how long the VMR 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 VMR will send additional
notification when the situation that caused the alarm has been corrected. For
example, when Notify Upon Clear is enabled, the VMR will send initial notification
when it detects that a current consumption has risen above the defined "High"
trigger value, and then send a second notification when it determines that current
consumption has fallen below the "Low" trigger value. (Default = On.)

On when current consumption at the plug rises above the user-defined high Plug
Threshold value. (Default = Leave On.)
Note: In order to enable Plug Shedding, you must first set the high Plug
Threshold value for each desired plug.
• Plug Group Shedding: Allows user-defined Plug Groups to be automatically
switched Off or left On when current consumption by the Plug Group rises above
the user-defined high Plug Group Threshold high. (Default = Leave On.)
Note: In order to enable Plug Group Shedding, you must first set the high Plug

10.SSH Encryption
In addition to standard Telnet protocol, the VMR/NPS also supports SSH connections,
which provide secure, encrypted access via network. In order to communicate with the
VMR/NPS using SSH protocol, your network node must include an appropriate
SSH client.
Note that when the /K (Send SSH Key) command is invoked, the VMR/NPS can also
provide you with a public SSH key, which can be used to streamline connection to the
VMR/NPS 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 VMR/NPS, and once this key is supplied to the
SSH client, the client will no longer display a warning indicating that the VMR/NPS 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
2. SSH2 RSA
3. SSH2 DSA
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.
Notes:
• Although the VMR/NPS 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.
11.1. Configuration
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 6.2, 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 6.8, 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.
Notes:
• 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 VMR/NPS, 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 8 is triggered.
11-1
12. SNMP Traps
The SNMP Trap function allows the VMR/NPS to send Alarm Notification messages to
two different SNMP managers, each time one of the Alarms discussed in Section 8 is
triggered.
Note:
• 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 8.
12.1. Configuration:
To configure the SNMP Trap function, proceed as follows:
1. Access command mode using an account that permits Administrator level
commands.
2. SNMP Trap Parameters: Access the SNMP Trap Parameters Menu as described in
Section 6.8.6. 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 8. 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.
Notes:
• 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 6.8.6.
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 VMR/NPS will send an SNMP Trap
each time an alarm is triggered.
12-1
13. Operation via SNMP
If SNMP Access Parameters have been defined as described in Section 6.8.5, 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 VMR/NPS 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. VMR/NPS SNMP Agent
The VMR/NPS’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 VMR/NPS 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 VMR/NPS, the default encryption
format for SNMPv3 is DES.) For the Password protocol, the SRM supports either MD5
or SHA1.

14. Creating Web Certificates
There are two different types of HTTPS security certificates: "Self Signed" certificates
and "Signed" certificates.
Note: SSL/TLS parameters cannot be defined via the Web Browser Interface. In order to set up SSL/TLS encryption, you must contact the VMR/NPS via the
Text Interface.
Self Signed certificates can be created by the VMR/NPS, without the need to go to an
outside service. The principal disadvantage of Self Signed certificates, is that when you
access the VMR/NPS 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 VMR/NPS is not recognized and that you may
not be connecting to the site that you intended.
Signed certificates must be created via an outside certificate authority (e.g., VeriSign®,
Thawte™, etc.) and then uploaded to the VMR/NPS unit to verify the unit's identity. Once
a signed certificate has been set up, you will then be able to access command mode
without seeing the warning message that is displayed for a Self Signed
certificate access.

Creating Web Certificates
14.1. Creating a Self Signed Certificate
To create a Self Signed certificate, access the Text interface using a password that
permits access to Administrator level commands and then proceed as follows:
1. Type /N and press [Enter] to display the Eth0/IPv4 (Shared) Network
Parameters menu.
2. At the Eth0/IPv4 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.
Notes:
• When configuring the VMR/NPS, make certain to define all of the following
parameters. Although most SSL/TLS applications require only the Common
Name, in the case of the VMR/NPS all of the following parameters are
mandatory.
• If desired, any random text sequence can be entered in each of these fields.
• 5. Common Name: A domain name that will be used to identify the VMR/NPS
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.yourcompanyname.com.)
• 6. State or Province: The name of the state or province where the VMR/NPS
unit will be located (e.g., California.)
• 7. Locality: The city or town where the VMR/NPS unit will be located (e.g.,
Irvine.)
• 8. Country: The two character country code for the nation where the VMR/NPS
will be located (e.g., US.)
• 9. Email Address: An email address, that can be used to contact the person
responsible for the VMR/NPS (e.g., jsmith@yourcompany.com.)
• 10. Organizational Name: The name of your company or organization
(e.g., Yourcompanyname, Inc.)
• 11. Organizational Unit: The name of your department or division.

password and then press [Enter]. When the VMR/NPS prompts you to verify
the password, key it again and then press [Enter] once. After a brief pause,
the VMR/NPS 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 VMR/NPS via the Web Interface, using an HTTPS connection.
a) Before the connection is established, the VMR/NPS should display the warning
message described previously. This indicates that the Self Signed certificate
has been successfully created and saved.
b) The VMR/NPS 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 12 and press [Enter] to access the
CSR Commands submenu.

15. Saving and Restoring Configuration Parameters
Once the VMR/NPS 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 VMR/NPS 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., 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.

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
VMR/NPS parameters to an XML format file on your PC or laptop. To save parameters
via the Web Browser Interface, proceed as follows:
Notes:
• Although VMR/NPS 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 proceeding with the download.
1. Access the Web Browser Interface command mode using an account that permits
Administrator level commands.
2. When the Web Browser Interface appears, click on the "Download Unit
Configuration" button on the left hand side of the screen.
3. 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 VMR/NPS.
Note: The Restore Parameters feature is only available via the Text Interface.
1. Start your terminal emulation program and access the VMR/NPS’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 VMR/NPS parameters. If necessary, key in
the file name and directory path.
4. Your terminal emulation program will send the ASCII text file to the VMR/NPS.
When the terminal program is finished with the upload, make certain to terminate
the Upload mode.
Note: If the VMR/NPS 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 VMR/NPS 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.
15-2
Saving and Restoring Configuration Parameters
15.3. Restoring Previously Saved Parameters
If you make a mistake while configuring the VMR/NPS unit, and wish to return to the
previously saved parameters, the Text Interface's "Reboot System" command (/I) offers
the option to reinitialize the VMR/NPS 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.
Notes:
• The VMR/NPS will automatically backup saved parameters once a day,
shortly after Midnight. This configuration backup file will contain only the
most recently saved VMR/NPS 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 mode via the Text Interface, using a username/password that
permits access to Administrator level commands (see Section 5.1.1.)
2. At the VMR/NPS command prompt, type /I and press [Enter]. The VMR/NPS 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 VMR/NPS will reboot and previously saved parameters will be restored.
15-3
16.Upgrading VMR/NPS Firmware
When new, improved versions of the VMR/NPS 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 VMR/NPS unit using the Firmware Upgrade Utility or the
Upgrade Firmware function.
16.1.WMU Enterprise Management Software (Recommended)
The preferred method for updating VMR/NPS units is via the WMU Enterprise
Management Software that is included with the unit. The WMU software allows you
to manage firmware updates for multiple WTI units from a single interface. For a
description of the process for managing firmware updates via the WMU, please refer to
the WMU user's guide, which can be downloaded from the WTI User's Guide Archive at:
http://www.wti.com/t-product-manuals.aspx
Note that in order to use the WMU software, the firmware version for the VMR/NPS must
be at least v1.48 or higher. When upgrading older VMR/NPS units that feature pre v1.48
firmware, it is recommended to use the WTI Firmware Upgrade Utility. 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:
ftp://wtiftp.wti.com/pub/TechSupport/Firmware/Upgrade_Utility/
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 VMR
firmware. Updates can be uploaded via FTP or SFTP protocols.
Notes:
• 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.
16-1
Upgrading VMR/NPS Firmware
3. When the command prompt appears, type /UF and then press [Enter]. The VMR/
NPS 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 VMR/NPS's operating
firmware. To update the WTI Management Utility only, type 4 and press
[Enter].
Note that after any of the above options is selected, the VMR/NPS 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 VMR/NPS 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
VMR/NPS unit, using a username and password that permit access to Administrator
level commands.
6. Transfer the md5 format upgrade file to the VMR/NPS.
7. After the file transfer is complete, the VMR/NPS 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 VMR/NPS will send a message to
all currently connected network sessions, indicating that the VMR/NPS is going
down for a reboot.
Note: Do not power down the VMR/NPS unit while it is in the process of
installing the upgrade file. This can damage the unit's operating system.
16-2
Upgrading VMR/NPS Firmware
8. If you have accessed the VMR/NPS via the Network Port, in order to start the FTP/
SFTP servers, the VMR/NPS 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 VMR/NPS using your former IP address.
• If you initially selected "Start FTP/SFTP Servers and Default Parameters",
you must then login using the VMR/NPS’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.
16-3
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 VMR/NPS Text Interface commands begin with the Slash
Character (/).
• 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].
