8.2 Resetting a Terminal Concentrator Connection

This section provides instructions for resetting a Terminal Concentrator connection.

If another user has a connection to the Sun Cluster node console port on the Terminal Concentrator, you can reset the port to disconnect that user. This procedure will be useful if you need to immediately perform an administrative task.

If you cannot connect to the Terminal Concentrator, the following message appears:

# telnet terminal-concentrator-name 5002
 Trying 192.9.200.1 ...
 telnet: Unable to connect to remote host: Connection refused
 #

If you use the port selector, you might see a port busy message.

8.2.1 How to Reset a Terminal Concentrator Connection

1. Press an extra return after making the connection and select the command line interface (cli) to connect to the Terminal Concentrator.

   The annex: prompt appears.

   # telnet terminal-concentrator-name ... Enter Annex port name or number: cli ... annex:

2. Enter the su command and password.

   By default, the password is the IP address of the Terminal Concentrator.

   annex: su Password:

3. Determine which port you want to reset.

   The port in this example is Port 2. Use the Terminal Concentrator's built-in who command to show connections.

   annex# who Port What User Location When Idle Address 2 PSVR --- --- --- 1:27 192.9.75.12 v1 CLI --- --- --- 192.9.76.10

4. Reset the port.

   Use the Terminal Concentrator's built-in reset command to reset the port. This example breaks the connection on Port 2.

   annex# admin reset 2

5. Disconnect from the Terminal Concentrator.

   annex# hangup

6. Reconnect to the port.

   # telnet terminal-concentrator-name 5002
