○ Wait for at least 10 minutes and check if the error resolves.
○ If the error persists, check that all modules in the enclosure are fully seated in their slots
and that their latches, if any, are locked.
○ If this does not resolve the issue, ensure the partner FRU is not degraded. If the partner
FRU is degraded, contact technical support.
○ For all FRU types except the enclosure, if the partner FRU is not degraded, remove and
reinsert the indicated FRU.
