3. If the previous steps do not resolve the problem, at the next maintenance opportunity, replace the affected DIMM
(as indicated by LightPath and/or failure log entry).
4. 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.
5. Check IBM support site for an applicable Service Bulletins (Service bulletins) that applies to this memory error.
