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. But an event code 400 displays when the switch

completes the POST/IPL process.

Was an event code 400 or 411 observed at the switch Event Log (HAFM

appliance) or at the Embedded Web Server Event Log?

YES NO

↓ Analysis for the failure is not described in this MAP. Go to “MAP 0000:

Start MAP” on page 29. Exit MAP.

The following table lists event codes, brief explanations of the codes, and the

associated steps that describe fault isolation procedures.

POST/IPL diagnostics detected a CTP failure as indicated by an event code 400

with supplementary bytes of event data.

■ Byte 0 is a FRU code (02) that indicates a failed CTP.

■ Byte 1 is the slot number (00) for the CTP.

Because the CTP card is not a FRU, CTP failure requires replacing the switch.
