1. Introduction
The CMS-16 Console Port Management Switch provides secure, in-band and/or out-of-band
access to RS232 console ports and maintenance ports on UNIX servers, routers and other
network equipment. System Administrators can access remote devices in order to change
configuration parameters, connect users to restricted ports, collect buffered data, and perform a
variety of other administrative functions.
Versatile Connectivity
Up to 16 different devices can be connected to the CMS without the need to select a common
baud rate or parity. Each port can be individually configured for specific baud rates, parity,
handshaking, and various other parameters and options.
Easy Set-Up and Operation
Configuration of the CMS is simple. A menuing system is used to select parameters, and
enable options. The CMS can easily adapt to the requirements of almost any data
communications application.
Limited Command Access
The CMS is ideal for situations that require limited access to important commands. Two
security levels allow each port to function as a Supervisor Port or User Port, depending on the
password entered at login. Supervisor Ports are allowed to change configuration, display
status, and connect to any other port; User ports are only allowed to connect to the ports
provided by their password. Each individual port can be assigned its own unique, user-defined
password, up to sixteen characters long.
Non-Volatile Memory
If AC power to the unit is lost or interrupted, the CMS’s
non-volatile memory will retain user-defined parameters and port connections.
Modem and Telnet Communication
The CMS can be controlled by a local PC that communicates with the unit via cable, or
controlled remotely via external modem or telnet connection. Your terminal emulation or
telnet program is used to send commands to connect ports or display status.
Configuration Backup
Once you have configured the CMS to fit your application, parameters and options can be
saved to an ASCII text file on your PC. This allows you to quickly restore user-selected
parameters if the unit configuration is accidentally altered or deleted. Saved parameters can
also be uploaded to other CMS units. This allows rapid set-up when several units will be
configured with identical or similar parameters.
