d. If this procedure does not fix the problem, call service support.
Firmware checkpoints
Firmware uses checkpoints (progress codes) in the range of Exxx to EFFF. These checkpoints occur
during system startup and can be useful in diagnosing certain problems. Service processor checkpoints
are listed in "Service processor checkpoints" on page 94.
If you have a checkpoint with no location code associated with it, see "Determining location code" on
page 126. If a checkpoint has a location code associated with a FRU replacement, see "Mapping AIX and
physical location codes" on page 21 for physical location information.
If you replace FRUs and the problem is still not corrected, go to "MAP 1548: Processor Subsystem
Problem Isolation" on page 77 unless otherwise indicated in the tables.
Notes:
1. If you receive a four-digit code in the range of E1xx to EFFF that is not listed in the following table, go
to "MAP 1548: Processor Subsystem Problem Isolation" on page 77.
2. Not all firmware checkpoints are supported.
