Warnings and Cautions:
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.

• LithiumBattery
CAUTION:Dangerofexplosionifbatteryisincorrectlyreplaced.Replace
onlywithsameorequivalenttyperecommendedbythemanufacturer.
Discardusedbatteriesaccordingtothemanufacturer'sinstructions.

ii
Warnings and Cautions
Disconnect Power
If any of the following events are noted, immediately disconnect the unit from the outlet
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.
Restricted Access Location
Equipment is intended for installation in Restricted Access Location.

Agency Approvals
FCC Part 15 Regulation
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy, and if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
• Reorientorrelocatethereceivingantenna.
• Increasetheseparationbetweentheequipmentandreceiver.
• Plugtheequipmentintoanoutletonacircuitthatisdifferentfromtheoneusedby
the receiver.
• Consultthedealeroranexperiencedradio/TVtechnicianforhelp.
This device complies with Part 15 of the FCC rules. Operation of this device is subject to
the following conditions: (1) This device may not cause harmful interference, and (2) this
device must accept any interference that may cause undesired operation.
WARNING: Changes or modifications to this unit not expressly approved by
the party responsible for compliance could void the user’s authority to operate
the equipment

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.
