This procedure will isolate a DIMM failure after the DIMM FRU failed to correct the problem.

  1. Power off the system (see Powering on and powering off).
  2. Place the DIMM that was replaced by the FRU callout back into its original location.
  3. Replace the DIMM that is paired with the DIMM FRU that was called out, according to the following table. See Locating FRUs for part numbers and a link to the exchange procedure.

  4. Performing a slow boot.
  5. Does the problem persist?
  6. Power off the system (see Powering on and powering off).
  7. Replace the board that the DIMM is plugged into using symbolic FRU isolates/frumembrd.dita#frumembrd.
  8. Performing a slow boot. This ends the procedure.
