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 toLocating 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 or 00000008?
    No:
    Go to the next step.
    Yes:
    Perform the following:
    1. The XYZ bus or the Processor - P5IOC2 bus has an error. Replace the FRUs called out after this procedure.
    2. Did replacing the FRUs correct the problem?
      Yes:
      This ends the procedure.
      No:
      Perform the following:
    3. Replace the Regulator Distribution Backplane (Un-P2) from the drawer the FRUs were replaced.
    4. Perform a slow boot. This ends the procedure.
  2. Is word 6 of the reference code 00000002?
    No:
    Go to the next step.
    Yes:
    Perform the following:
    1. The AB bus has an error. Replace the SMP Cable (Un-P2-Cx-Tx is the connector location) between the FRUs called out after this procedure.
    2. Clear the deconfiguration errors for the FRUs called out.
    3. Perform a slow boot.
    4. Did replacing the SMP Cable correct the problem?
      Yes:
      This ends the procedure.
      No:
      Perform the following:
    5. Replace the FRUs called out after this procedure. This ends the procedure.
  3. Is word 6 of the reference code 00000004 or 00000005?
    No:
    Go to the next step.
    Yes:
    Perform the following:
    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?
      Yes:
      This ends the procedure.
      No:
      Perform the following:
    3. Replace the Regulator Distribution Backplane (Un-P2) from the drawer where the FRUs were replaced.
    4. Perform a slow boot. Does the problem persist?
      No:
      This ends the procedure.
      Yes:
      Perform the following:
    5. Replace the System Backplane (Un-P1) from the drawer where the FRUs were replaced.
    6. Perform a slow boot. This ends the procedure.
  4. 4. Is word 6 of the reference code 00000006?
    No:
    Go to the next step.
    Yes:
    Perform the following:
    1. The DIMM - DIMM bus has an error. Replace the FRUs called out after this procedure.
    2. Did replacing the FRUs correct the problem?
      Yes:
      This ends the procedure.
      No:
      Perform the following:
    3. Replace the Processor Card (Un-P2-C1 or Un-P2-C2) from the drawer where the FRUs were replaced.
    4. Perform a slow boot. This ends the procedure.
  5. 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.
