Chapter 8 Troubleshooting

Problem Solving Using a Subsystems Approach

Troubleshooting the Management Subsystem

Check the following to help isolate a problem in the management subsystem.

Problems in the management subsystem could be any of the following:

Management link is down. (Mng LINK LED not lit--also Status is WARNING)

Management link is up (Mng LINK LED lit) but does not answer ping

Telnet connection cannot be established due to link problems (Mng LINK LED not lit)

Management link is up (Mng LINK LED lit) but Telnet connection cannot be established

Telnet connection established, but terminates automatically

Note When the management link is down and/or a Telnet connection cannot be established, you must open a CLI session on a local terminal connected to the CON port. This enables you to solve the problem and then reconnect through the management port.
