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.
