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 program load (IPL) that loads firmware and
brings the unit online. This MAP describes fault isolation for problems that may occur during
the POST/IPL process.
If an error is detected, the POST/IPL process continues in an attempt to initialize the switch
and bring it online. An event code
400
is displayed when the switch completes the POST/IPL
process.

(amber).
•
Audio emanations and airflow from cooling fans.
