Troubleshooting Supervisor Engines

Useful CLI Commands

Some problems can be solved by resetting the supervisor engine. Use the hw-module module <n> reset
power-cycle command to reset a switching module, or remove and re-insert the switching module,
which resets, restarts and power cycles the switching module. Pressing the reset button on the supervisor
engine causes the software to reload, but does not power cycle the supervisor engine.
When you power-cycle or remove a supervisor engine in a redundant system the other supervisor engine
Note
becomes the active supervisor and the ports retain connectivity. In a non-redundant system, all of the
switching modules lose connectivity until the supervisor engine is reinserted and completely restarted.
The show diagnostics power-on command may provide useful information for some supervisor engine
problems.
Not all software versions support all supervisor engines. If you are having trouble with a supervisor
engine, refer to the software release notes to be sure that it is supported by your software.

Standby Supervisor Engine Problems

If the standby supervisor engine module is not online or status indicates "other" or "faulty" in the output
of the show module command or an amber status LED, create a console connection to the standby
supervisor engine and verify that it is in ROMmon mode or in continuous reboot. If the standby
supervisor engine is in either of these two states, refer to:

Make sure that the supervisor engine module properly seats in the backplane connector and that you have
completely screwed down the captive screws for the supervisor engine.
In order to determine whether the standby supervisor engine is faulty, enter the redundancy reload peer
command from the active supervisor engine and through the console to the standby supervisor engine.
Observe the bootup sequence in order to identify any hardware failures. Currently, the active supervisor
engine cannot access the power-on diagnostics results of the standby supervisor engine.
Make sure that these configurations are synchronized between the active and redundant supervisor
engines:
