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.
