1. If the node has recently been installed, moved,
serviced, or upgraded, verify that the DIMM is
properly seated and visually verify that there is no
foreign material in any DIMM connector on that
memory channel. If either of these conditions is
found, correct and retry with the same DIMM.
(Note: Event Log may contain a recent 00580A4
event denoting detected change in DIMM
population that could be related to this problem.)
2. Check IBM support site for an applicable firmware
update that applies to this memory error. The
release notes will list the known problems the
update addresses.
3.
If PFA re-occurs on the same DIMM connector,
swap the other DIMMs on the same memory
channel one at a time to a different memory channel
or Processor. (check service information for this
product/Install guide for population requirements
for sparing/paring modes). If PFA follows a moved
DIMM to any DIMM connector on the different
memory channel, replace the moved DIMM.
4. (Trained service technician only) If problem
continues to re-occur on the same DIMM connector,
inspect DIMM connector for foreign material and
remove, if found. If connector is damaged, replace
system board.
5. (Trained service technician only) Inspect processor
socket for foreign debris or damage. If debris is
found, remove debris.
6. (Trained service technician only) Remove affected
processor and inspect processor socket pins for
damaged or mis-aligned pins. If damage is found
on processor, replace system board.
7. (Trained Service technician only) Replace affected
processor.
W.58007 [W.58007] Invalid memory configuration
(Unsupported DIMM Population)
detected. Please verify memory
configuration is valid.
Explanation: Unsupported DIMM Population
Severity: Error
User response: Complete the following steps:
1.
Could follow an uncorrectable memory error or
failed memory test. Check log and service that
event first. DIMMs disabled by other errors or
actions could cause this event.
2. Ensure that the DIMM connectors are populated
according to the guidelines in the service
information for this product.

for Sparing Mode. Please correct
memory configuration.
Explanation: Unsupported DIMM Population for
Spare Mode
Severity: Error
User response: Complete the following steps:
1. Make sure that the DIMM connectors are correctly
populated for sparing mode, according to the
service information for this product.
W.68002 [W.68002] A CMOS battery error has
been detected
Explanation: CMOS Battery Fault
Severity: Error
User response: Complete the following steps:
1. If the system was recently Installed, Moved, or
Serviced, make sure the battery is properly seated.
2. Check IBM support site for an applicable service
bulletin or firmware update that applies to this
error.
3. Replace CMOS Battery
4. (Trained Service technician only) Replace the
system board.
