1. Introduction
CMS Series Console Port Management Switches provide 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-16
without the need to select a common baud rate or parity (the
CMS-8 can be connected to up to eight different devices). 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
Limited Command Access
The CMS is ideal for situations that require limited access to
important command functions. 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
