CMS-Series Telnet and Dial-Up Console/Aux Port Switch
*Product End-of-Life Notice: Contact WTI For Replacement Models*
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 tasks. The CMS is ideal for colocation applications; two different password security levels protect access to restricted ports and configuration commands. Users are allowed to connect to only the ports provided by their passwords, while supervisors are allowed to connect to any port or invoke configuration commands.
Intelligent Port Selection
Each port can be individually accessed by number, name, or group. Ports can be individually configured using simple, menu driven commands to set passwords, data rates, parity, flow control and many other operating parameters. The full matrix capability of the CMS allows any port to connect to any other port on the switch. Ports can also be connected or disconnected by a third party with supervisor rights. For example, systems managers can swap various RS232 devices between ports on a terminal server at a remote location. Configuration and Status screens display port parameters and connection activity for one or all ports.

Security and Co-Location Features
Address-specific IP security masks prevent unauthorized access to the CMS menu via network. Two levels of operational passwords are also available; the System Administrator level and the User level. The System Administrator level is used to configure the unit, assign passwords and access privileges, and create connections to any port. The User level allows connections only to assigned ports. The User level is ideal for co-location applications, as users can only view status and connect to ports assigned to their password.

Capture Buffer
The "Buffer Mode" feature allows individual ports to capture and store incoming data. This "snapshot" of the last 32K of received data is stored in non-volatile memory, and can be viewed, saved or erased by the system administrator at any time. This is particularly useful in the event that alarm information or other critical data is sent to a specific port during non-connect periods.
