configuration, confirm that the target PCIe card can be removed from the
multipath I/O configuration. For details, see the manual for the software being
used.
To perform active replacement in combination with the dynamic SR-IOV function
■
or the dynamic reconfiguration function for a PCIe endpoint, the PCIe card to be
replaced must support the respective function.
For details, see "Appendix C Cards/On-Board Devices That Support SR-IOV"
and "Appendix D Cards/On-Board Devices That Support Assignment of PCIe
End Point Devices (PCIe Cards)" in the Fujitsu SPARC M12 PCI Card Installation
Guide.
Precautions for OPNL replacement
Caution - Remove all HDDs/SSDs from the HDDBPU. Replacing the OPNL without
removing the HDDs/SSDs may damage them.
When replacing the OPNL in the SPARC M12-2S, set the BB-ID of the OPNL after
■
replacement to the same value as that used before replacement.

Precautions for FRU Expansion
This section describes the precautions for FRU expansion.
Before performing expansion work, see
Identifying a
expansion.
Precautions for CMUU expansion
Caution - The CMUU weighs 10 kg (22 lb). Work must be done by two people if the
chassis is mounted at the 24U or higher position of the rack. If the work is done by
one person, it may result in an injury or damage to the chassis.
When adding the CMUU, remove the CMU filler unit. Store the removed CMU
■
filler unit in a safe place.
Adding the CMUU also adds a root complex. Enabling the I/O bus reconfiguration
■
function increases the I/O bandwidth. Since doing so changes the PCIe card
installation rules and the device path of the I/O device, you may need to
reconfigure the logical domains.
For details, see "A.2 SPARC M12-2 Device Paths" or "A.3 SPARC M12-2S
Device Paths" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 System
Operation and Administration Guide.
To use the added CPU resources after CMUU addition, you need to assign CPU
