Firmware Checkpoints
Firmware uses progress codes (checkpoints) in the range of E1xx to EFFF. These
checkpoints occur during system startup and maybe be useful in diagnosing certain
problems. Service Processor checkpoints are listed in “SP Checkpoints” on
page 3-30.
If you replace FRUs and the problem is still not corrected, go to “MAP 1540:
Minimum Configuration” on page 2-25 unless otherwise indicated in the tables.
Table 3-4 (Page 3 of 3). SP Checkpoints.
