16.4 Precautions for Motherboard Unit
Replacement
Note the following points when replacing the motherboard unit.
■
Do not replace the motherboard unit and the PSU backplane at the same time. 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.
■
Do not mount and use any of the following microSD cards in the motherboard
unit 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 microSD cards store device identification information.

The CPU and XSCF on the motherboard unit cannot be replaced individually.
Replace the motherboard unit.
■
When replacing the motherboard unit, the memory should be removed from the
old unit and remounted on the new unit. Always mount the memory modules in
the same locations as they were mounted on the old motherboard unit.

the system setting information. When the motherboard unit is replaced, the CPU
Activation setting information and CPU Activation key may be deleted. To restore
the CPU Activation setting information and CPU Activation key 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
