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 79.
Attention: If you replace FRUs or perform an action and the problem is still not
corrected, go to “MAP 1540: Minimum Configuration” on page 52 unless otherwise
indicated in the tables.
If you replace FRUs or perform an action and the problem is corrected, go to ″MAP
410: Repair Checkout″ in
Diagnostic Information for Multiple Bus Systems .
Note: Firmware can hang due to multiple causes. In many cases, it can be caused by
the primary processor or a memory problem in the first 64 MB of real memory. If
a location code is not provided with the checkpoint, the following procedure will
use the primary processor and low memory as the probable FRUs.
1. If firmware is hung (E100 through EFFF) and a location code is displayed on
the second line of the operator panel, use that location code as the primary
FRU.
2. If no location code is present or if replacing the primary FRU indicated in the
location code did not fix the problem, then perform the following action:
a. Power off the system and go to the service processor menus.
b. From the service processor main menu, select option 3, System
Information Menu, then select option 5, Read NVRAM.
c. Enter 330 when prompted for an address.
d. Look at the byte of data at address 330. If the value is FF, go to note 3. If
the value is 00-0F, replace the processor card, location: P1-C1. Attempt
to reboot the system. If the system hangs at the same checkpoint, go to
note 3. If the system hangs at a new checkpoint, perform the actions
associated with the new checkpoint.
3. Power off the system. From the service processor main menu, select option
3, System Information Menu, then option 8, Memory
Configuration/Deconfiguration Menu. Identify the first configured DIMM
pair if DIMMs reside on a one-way processor card, or the first configured
memory riser card and quad of DIMMs. Replace the first group of DIMMs.
4. If replacing the first group of configured DIMMs does not fix the problem,
replace the memory riser card. If the problem is still not fixed, go to “MAP
1540: Minimum Configuration” on page 52.
