Checkpoints enable users and service personnel to 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 a 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, check for additional symptoms in the
service processor error log. See the "System Information Menu" on page 301 for
information on how to access the service processor error log.
Note: Go to "MAP 1540: Minimum Configuration" on page 101 for any of the following
checkpoint hang conditions:
v A four-digit code in the range of 8xxx through EFFF not listed in the
checkpoint tables.
v A four-digit code is in the checkpoint tables, 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.
Checkpoints listed in the following tables are in the format 8xxx, 9xxx, Axxx, Bxxx, or
Exxx, where x is any hexadecimal digit from 1-9 or A-F. If your system hangs with a
checkpoint displayed that begins with anything other than 8, 9, A, B, or E, go to the
RS/6000 Eserver pSeries Diagnostic Information for Multiple Bus Systems .
Use the following table to determine where to find the checkpoint.
