2. If no memory fault is recorded in the logs and no DIMM connector error LEDs are lit, verify that
all DIMM connectors are enabled using the Setup utility or the Advanced Settings Utility (ASU).
3. Re-Install all DIMMs verifying the correct population sequence, according to the service
information for this product.
4. (Trained service technician only) Replace the processor.

Complete the following steps:
1. You must AC-cycle the system to re-enable affected DIMM connector or re-enable manually
using F1 setup
2. If the node has been recently installed, serviced, moved, or upgraded, check to ensure that
DIMMs are firmly seated and that no foreign material can be seen in the DIMM connector. If
either condition is observed, 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.)
3. If problem persists, replace the DIMM identified by LightPath and/or event log entry.
4. If problem re-occurs on the same DIMM connector, swap the other DIMMs on the same memory
channel across channels 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 problem follows a moved DIMM to a different memory channel, replace that DIMM.
5. Check IBM support site for an applicable service bulletin or firmware update that applies to this
memory error.
6. (Trained service technician only) If problem stays with the original DIMM connector, re-inspect
DIMM connector for foreign material and remove, if found. If connector is damaged, replace
system board.
7. (Trained service technician only) Remove affected Processor and inspect Processor socket pins
for damaged or mis-aligned pins. If damage is found, or this is an upgrade Processor, replace
system board. If there are multiple Processor's, swap Processor's to move affected Procesor to
another Processor socket and retry. If problem follows the affected Processor (or there is only
one Processor), replace the affected Processor.
8. (Trained Service technician only) Replace the system board.
