MAP 0200: POST failure analysis
This MAP describes fault isolation for power-on self-test (POST)
failure. The failure indicator are event codes observed at the Event Log
(EFCM Basic Edition or Element Manager interface).
1
Table 10 lists event codes, explanations, and MAP steps.

POST/IPL diagnostics detected a FRU failure.
a. At the Event Log, examine the first two bytes (0 and 1) of event
data.
b. Byte 0 indicates the failed component. Byte 1 is the slot number
of the failed FRU (00 for a nonredundant FRU, 00 or 01 for
redundant FRUs, and 00 through 34 for port cards.
Table 11 lists byte 0 FRU codes and associated steps that describe
fault isolation procedures.
