MAP 0200: POST Failure Analysis
When the switch is powered on, it performs a series of power-on self-tests
(POSTs). When POSTs complete, the switch performs an initial machine load
(IML) that loads firmware and brings the unit online. This MAP describes fault
isolation for problems that may occur during the POST/IML process.
If an error occurs, the POST/IML process continues in an attempt to initialize the
switch and bring it online. An event code 400 displays when the switch completes
the POST/IML process.
