These system messages indicate a problem with the supervisor engine. Some problems will prevent a console connection and will not allow you to use messages in diagnosing a problem. If you are unable to establish a terminal connection and the STATUS LED is red, contact Cisco TAC immediately to order a replacement.

Problems with redundant supervisor systems are often due to mismatched active and standby supervisor engines. Redundancy requires that both supervisor engines be the same model and running the same Cisco IOS release. If one supervisor has a NetFlow service card, the other must as well.

Some problems with supervisor engines are due to backplane connections that are not fully seated. If removing and reinserting the supervisor engine and then restarting the switch does not solve the problem, call Cisco TAC and replace the supervisor engine.
