16.4 Precautions for MBU Replacement


16.4 Precautions for MBU Replacement
Note the following points when replacing the MBU.
  1. Do not replace the MBU and the PSUBP at the same time. If you replace the MBU and the PSUBP at the same time, the system may fail to operate correctly. Replace the MBU or PSUBP, execute the showhardconf or showstatus command, and confirm that the replacement Field Replaceable Unit (FRU) is fully operational. Then, replace the other FRU.
  2. Do not mount and use any of the following SD cards in the MBU in another chassis:
    - the one currently mounted in the SPARC M12-1, or

    - one that was once used as a maintenance part

    This is because these SD cards store device identification information.
  3. The CPU and XSCF on the MBU cannot be replaced individually. Replace the MBU.
  4. When replacing the MBU, you need to remove memory from the old unit and reinstall it on the new unit. Always install the memory modules at the same locations as on the old motherboard unit.
  5. Before replacing the MBU, execute the dumpconfig command to save the system setting information. When the MBU is replaced, CPU Activation setting information and CPU Activation keys may be deleted. To restore the CPU Activation setting information and CPU Activation keys that have been saved with the dumpconfig command, execute the restoreconfig command. For details, see "10.10 Saving/Restoring XSCF Settings Information" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 System Operation and Administration Guide.
  6. Set the system time.
    After replacing the MBU, 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 SPARC M12 Product Notes for the latest XCP version.
  7. If you replace the SD card along with the MBU, dispose of the SD card mounted on the old MBU by appropriate means such as cutting it with cutting pliers.
    The old SD card stores the user information, IP address, and other information set in the XSCF firmware.
