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.
