1. Introduction
This User's Guide covers three WTI product lines: TSM Series Serial Console Servers,
RSM Series Remote Site Managers and RSM-xRy Series Remote Site Managers with
Power Control . All four of these product lines are designed to simplify the process of
remotely managing vital network elements located at distant network equipment sites
and off-site facilities. The TSM and RSM lines both provide remote access to console
port command functions on faraway network elements. RSM-xRy Series units provide
remote access to console ports on distant network equipment and also include the
ability to remotely control power switching and reboot functions at the remote network
equipment site.
Security and Co-Location Features:
Secure Shell (SSHv2) encryption and address-specific IP security masks help to prevent
unauthorized access to command and configuration functions.
The TSM/RSM provides four different levels of security for user accounts: Administrator,
SuperUser, User and ViewOnly. The Administrator level provides complete access to
all serial port and switched plug functions, status displays and configuration menus.
The SuperUser level allows control of serial ports and plugs, but does not allow access
to configuration functions. The User level allows access to only a select group of
Administrator-defined serial ports and plugs. The ViewOnly level allows you to check
unit status, but does not allow control of serial ports or switched outlets or access to
configuration menus. The TSM/RSM includes full Radius, LDAP and TACACS capability,
DHCP, an IP Address filter and an invalid access lockout feature. An Audit Log records
all user access, login and logout times and command actions, and an Alarm Log
records user-defined alarm events.
Environmental Monitoring and Management:
The TSM/RSM can constantly monitor temperature levels, ping response and other
factors. If the TSM/RSM detects that user defined thresholds for these values have
been exceeded, the unit can promptly provide notification via email, SNMP, or Syslog.
When temperature readings exceed user-defined critical values, the TSM/RSM can also
intelligently decrease the amount of heat being generated within the rack by temporarily
shutting down nonessential devices; when readings return to acceptable levels, the
TSM/RSM can restore power to those devices to return to normal operating conditions.
The TSM/RSM also records temperature readings to a convenient log file.
In addition to the capabilities described above, RSM-8R8-CM series units include
current monitoring capabilities, allowing the unit to monitor and report current, power
and voltage conditions at remote equipment sites. If current or power usage exceeds
user-defined threshold values, the RSM-8R8-CM can also generate alarms and shut
down user-designated non-essential devices.
