Chapter 62 Performing Diagnostics

Note On a redundant chassis, concurrent POST is supported on supervisor engines that are already inserted.

However, if a second supervisor engine is inserted while the first one is loading, you might boot the first

supervisor engine in a faulty Cisco IOS state (POST will abort and some of the POST’s tests will be

bypassed). This situation only happens during concurrent bootup of the supervisor engines. You should

not insert any additional supervisor engines in the empty supervisor engine slot while an already seated

supervisor engine is running POST. The POST sequence is completed when the “Exiting to ios...”

message is displayed.
