12.3 Precautions for Maintaining the PSU Backplane
Note the following points when replacing the PSU backplane.
  1. If you replace the motherboard unit and the PSU backplane at the same time, the system may fail to operate correctly. Replace the motherboard unit or the PSU backplane, and then execute the showhardconf or showstatus command to verify that the replaced Field Replaceable Unit (FRU) is fully operational. Then, replace the other FRU.
  2. Do not mount and use any of the following PSU backplanes in another chassis:
    - the one currently mounted in the SPARC M10-1, or

    - one that was once used as a maintenance part

    This is because these PSU backplanes store device identification information.
  3. Set the system time.
    After replacing the PSU backplane, you need to set the system time. For details, see "Notes on Maintenance of a CPU Memory Unit, Motherboard Unit, XSCF Unit, PSU Backplane, or Crossbar Backplane Unit" in the Fujitsu M10/SPARC M10 Systems Product Notes for the latest XCP version.
