operation panel to Service mode
3 Checking the operating condition
of the system and the I/O device
usage status
4 Stopping the system
5 Releasing the chassis requiring
maintenance from the system
6 Enabling access to the FRU
requiring maintenance
7 Replacing a faulty FRU
8 Restoring the chassis requiring
maintenance
9 Incorporating the chassis requiring
maintenance into the system
10 Diagnosing the replacement FRU
11 Confirming that there is no
problem with the replacement FRU
12 Returning the mode switch on the
operation panel to Locked mode
13 Starting the system
14 Closing the rack door
*1 Simultaneous replacement of the CPU memory unit lower and PSU backplane unit is prohibited. To replace the CPU memory unit
lower and PSU backplane unit, first replace either of the units and perform the work up to "11. Confirming that there is no problem with
the replacement FRU." Then, return to "6. Enabling access to the FRU requiring maintenance," and replace the other unit.
*2 If a CPU memory unit lower is replaced in the system of the hardware RAID volume in a hardware RAID configuration using internal
disks, you need to reactivate the hardware RAID volume before performing the work in "13. Starting the system." For details, see "14.2.11
Re-enabling a Hardware RAID Volume" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 System Operation and Administration
