Precautions For Installation - Fujitsu M10-4 Service Manual

CPU clocks.
Note the following point when replacing a PCIe card:
For active maintenance by PHP, a multipath setting is necessary depending on the
■
use of the PCIe cards.
For active maintenance by PHP, confirm that the card is PHP supported. To do so,
■
check "Appendix A Cards that Support PCI Hot Plug and Dynamic Reconfiguration"
in the Fujitsu M10/SPARC M10 Systems PCI Card Installation Guide.To perform
active replacement using PHP combined with dynamic SR-IOV and the dynamic
reconfiguration function of PCIe end point devices, check the applicable cards by
referring to "Appendix B Cards that Support SR-IOV" or "Appendix D Cards
that support the dynamic reassignment function for the PCIe end point device
(PCIe card)" in the same manual.
Note the following points when replacing the operation panel:
To replace the operation panel, remove the PSU backplane from the chassis.
■
To replace the operation panel, set the BB-ID of the replacement operation panel to
■
the same value as that before replacement.

Precautions for installation

Note the following points when performing CPU memory unit upper or memory
installation:
When installing a CPU memory unit upper, remove the filler unit. Store the
■
removed filler unit in a safe place because it will be needed if you subsequently
remove the CPU memory unit upper.
If PCI Express cables are not connected to the CPU memory unit lower, you need
■
to add PCI Express cables.
If PCI Express cables are connected to the CPU memory unit lower, you need to
■
add only one PCI Express cable.
If the CPU memory unit upper for the 2CPU configuration of the SPARC
■
M10-4/M10-4S is installed, the root complex is also installed. Then, due to the I/O
bus reconfiguration function
installation rules
the device path of the I/O device
domains.
The type of CPU memory unit varies depending on the number of CPU clocks.
■
They cannot be mixed in the same device, but they can be mixed in a system with
a building block configuration.
Observe the memory installation rules when you expand memory. For details, see
■
"2.2.1 Memory installation
When you expand memory by 64 GB, apply XCP 2090 or later.

(*1)
, the I/O bandwidth increases, and the PCIe card

change. In addition, the I/O bus reconfiguration also changes
(*3)
, so you may have to reconfigure the logical
rules."
