Connecting an Appliance to a Terminal Server
Connecting an Appliance to a Terminal Server
A terminal server is a router with multiple, low speed, asynchronous ports that are connected to other
serial devices. You can use terminal servers to remotely manage network equipment, including
appliances. To set up a Cisco terminal server with RJ-45 or hydra cable assembly connections, follow
these steps:
Step 1
Connect to a terminal server using one of the following methods:
•
For terminal servers with RJ-45 connections, connect a rollover cable from the console port on the
appliance to a port on the terminal server.
•
For hydra cable assemblies, connect a straight-through patch cable from the console port on the
appliance to a port on the terminal server.
Step 2
Configure the line and port on the terminal server. In enable mode, enter the following configuration,
where # is the line number of the port to be configured.

Step 3
Be sure to properly close a terminal session to avoid unauthorized access to the appliance. If a terminal
session is not stopped properly, that is, if it does not receive an exit(0) signal from the application that
initiated the session, the terminal session can remain open. When terminal sessions are not stopped
properly, authentication is not performed on the next session that is opened on the serial port.
Caution
Always exit your session and return to a login prompt before terminating the application used to establish
the connection.
Caution
If a connection is dropped or terminated by accident, you should reestablish the connection and exit
normally to prevent unauthorized access to the appliance.
