FSPSP42

An error communicating between two system processors was detected.

Refer to System FRU locations for instructions on locating FRUs found on your system.

There is a communication error between the processors and the FRUs called out before this procedure. If you were unable to correct the problem by replacing FRUs that were previously specified before coming to this procedure, consider the possibility of failing system backplanes.

If you are servicing a 8234-EMA, 9117-MMA, and 9406-MMA, go to 8234-EMA, 9117-MMA, and 9406-MMA

All systems except 8234-EMA, 9117-MMA, and 9406-MMA

Perform the following task:
  1. Power off the system. See Powering on and powering off the system.
  2. Replace the system backplane (Un-P1).
  3. Perform a slow boot. See Performing a slow boot . This ends the procedure.
8234-EMA, 9117-MMA, and 9406-MMA
  1. Use the location codes for the FRUs that were previously specified to determine if the system processors are on separate nodes. Are the system processors on separate nodes?
    No:
    Continue with step 2.
    Yes:
    Do the following:
    1. Power off the system. See Powering on and powering off the system.
    2. Replace the SMP cables between the two enclosures.
    3. Perform a slow boot. See Performing a slow boot.
    4. Is the problem resolved?
      Yes:
      This ends the procedure.
      No:
      Continue with the next step.
  2. Power off the system. See Powering on and powering off the system
  3. Replace the bad node backplane.
  4. Perform a slow boot. See Performing a slow boot. This ends the procedure.
