Chapter 4. Checkpoints
Checkpoints let users and service personnel know what the system is doing, with some
detail, as it initializes. These checkpoints are not intended to be error indicators, but in
some cases the system could hang at one of the checkpoints without displaying an
8-character error code. It is for these hang conditions, only, that any action should be
taken with respect to checkpoints. The most appropriate action is included with each
checkpoint.
Before taking actions listed with a checkpoint, it is a good idea to look for more
appropriate symptoms in the service processor error log. See Chapter 7, “Using the
Service Processor”, on page 149.
Service Processor Checkpoints
Service processor checkpoints are in the range E001 to E0FF. The message OK
indicates successful service processor testing and initialization. Firmware checkpoints
are listed in “Firmware Checkpoints” on page 75.
Note: Go to “MAP 1540: Minimum Configuration” on page 50 for any of the following
conditions:
v A four-digit code in the range of E001 through EFFF displays on the operator panel
but is not listed in the checkpoint table.
v A four-digit code displays in the checkpoint table, but does not contain a repair action
or FRU listing.
v
All of the FRUs listed in the repair action have been replaced and the problem has
not been corrected.
If you replace FRUs or perform an action, and the problem is corrected, go to "MAP
410: Repair Checkout" in the
RS/6000 and
