Item Work procedure
14 Closing the rack door
*1 Simultaneous replacement of the CPU memory unit and PSU backplane unit is prohibited. To replace the CPU memory unit and PSU
backplane unit, first replace either of the units and perform the work up to "9. Incorporating the chassis requiring maintenance into the
system." Then, return to "5. Releasing the chassis requiring maintenance from the system," 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 starting Oracle Solaris. Start Oracle Solaris on the control domain as
described in "13. Powering on the chassis requiring maintenance." 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 Guide.
*3 The testsb command is executed during replacefru command processing. However, if that is canceled, diagnose the system board
before incorporating the chassis requiring maintenance into the physical partition.

System-stopped replacement

This section describes the workflows for system-stopped/hot and system-stopped/
cold FRU replacement. References to detailed descriptions are written in the
workflow. See any of them as required.
System-stopped replacement has the following patterns:
System-stopped/hot replacement (for a power supply unit or fan unit)
■
System-stopped/hot replacement (for an internal disk or PCIe card)
■
System-stopped/cold replacement (for a single-chassis configuration)
■
System-stopped/cold replacement (for a building block configuration)
■
System-stopped/all power-off cold replacement (for a building block configuration)
