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.
Both VMR and NPS Models:
This user's guide covers both VMR series Managed Power Controllers and NPS series
Network Power Switches. When features are available to both VMR and NPS series
models, this users guide will refer to the model as VMR/NPS. The text will also note
features that are not available to NPS models.
