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.
■
Before replacing the motherboard unit, execute the dumpconfig command to save
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
SPARC M12 and Fujitsu M10/SPARC M10 System Operation and Administration
Guide .
■
Set the system time.
After replacement of the motherboard unit has been completed, 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.
■
Check the XCP version.
If you replace the motherboard unit and switch the microSD card, the CMU
firmware versions displayed for the current and reserve XCPs by the version
command do not match when you check the XCP firmware version after executing
the testsb command. This does not affect system operation. If you start the system
when the current and reserve XCPs have been switched, the CMU firmware stored
on the microSD card is automatically applied.
■
The type of motherboard unit varies depending on the number of CPU clocks.
■
If you replace the microSD card along with the motherboard unit, dispose of the
microSD card mounted on the old motherboard unit by appropriate means such
as cutting it with cutting pliers. The old microSD card stores the user information,
IP address, and other information set in the XSCF firmware.
Precautions for memory replacement
■
When you replace a memory module, make sure that you install the new module
in the same position as the original one.
Precautions for PSU backplane replacement
■
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 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.
■
Set the system time.
After replacement of the PSU backplane has been completed, set the system time.
