62 Edge Switch 2/24 Service Manual

POST/IPL diagnostics detected a FRU failure as indicated by event code 400 with

supplementary event data.

1. At the EWS Event Log or the Edge Switch Event Log, examine the first two

bytes (0 and 1) of event data associated with event code 400.

2. Byte 0 is a FRU code that indicates the failed component. Byte 1 is the slot

number of the failed FRU (00 for a nonredundant FRU, and 00 or 01 for

redundant FRUs).

Table 7 lists byte 0 FRU codes and associated steps that describe fault isolation

procedures.

The CTP card failed POSTs (as indicated by FRU code 02). Replace the switch.

Exit MAP.

A fan module failed POSTs (as indicated by FRU code 05) and the power supply

containing the fan must be removed and replaced. Refer to “RRP: Redundant

Power Supply” on page 198.

■ This procedure is concurrent and can be performed while switch power is on.
