FSPSP55

An error has been detected on a bus between two FRUs. The endpoint FRUs have been called out, however, the source of the error could be the bus path between the FRUs.

Refer to Locating FRUs for instructions for removing and replacing any FRUs called out by the following procedure.

  1. Is word 6 (the 8 leftmost characters of Panel function 13) of the reference code 00000001?
    1. The XYZ bus has an error. Replace the FRUs called out after this procedure.
    2. Did replacing the FRUs correct the problem?
      No:
      Continue to the next step.
      Yes:
      This ends the procedure.
    3. Replace the system backplane (Un-P1).
    4. Perform a slow boot. This ends the procedure.
  2. Is word 6 of the reference code 00000002?
    1. The AB bus has an error. Replace the FRUs called out after this procedure.
    2. Did replacing the FRUs correct the problem?
      No:
      Continue to the next step.
      Yes:
      This ends the procedure.
    3. Replace the system backplane (Un-P1).
    4. Perform a slow boot. This ends the procedure.
  3. Is word 6 of the reference code 00000004 or 00000005
    1. The Processor - GX Card bus or PSI bus has an error. Replace the FRUs called out after this procedure.
    2. Did replacing the FRUs correct the problem?
      No:
      Continue to the next step.
      Yes:
      This ends the procedure.
    3. Replace the system backplane (Un-P1).
    4. Perform a slow boot. This ends the procedure.
  4. For any other value in word 6 of the reference code, the bus error is corrected by the FRUs called out after this procedure. Replace the FRUs called out after this procedure. This ends the procedure.
  5. Replace the System Backplane (Un-P1), then Perform a slow boot. This ends the procedure.
