4.3.2 Precautions for installation
4.3.2 Precautions for installation
Before performing installation work, see "Checking the FRU status" in "4.2.2 Identifying a failure" to confirm that there is no problem with the chassis requiring installation.
Precautions for expansion of the CPU memory unit upper
- 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, by enabling the I/O bus reconfiguration function(*1), the I/O bandwidth increases, and the PCIe card installation rules(*2) change. In addition, the I/O bus reconfiguration also changes the device path of the I/O device(*3), so you may have to reconfigure the logical 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.

Precautions for memory expansion
- Observe the memory installation rules when you expand memory. For details, see "2.2.1 Memory installation rules."
- When you expand memory by 64 GB, apply XCP 2090 or later.
- Unless memory modules of 512 GB (64 GB DIMM x 8) are mounted in the 16 DIMM slots under a CPU, memory modules of up to two different capacities can be mounted together. In this case, use the same type within each memory group.
| Note - When you expand memory with a different capacity, apply XCP 2052 or later. |
Precautions for internal disk expansion
- To expand an internal disk, remove the hard disk drive filler unit from the slot in which you will install the internal disk. Store the removed filler unit in a safe place because it will be needed if you subsequently remove the internal disk.
Precautions for PCIe card expansion
- Set a multipath depending on the use of the PCIe card when performing active/hot maintenance or active/cold maintenance with PHP.
- For active addition using PHP, confirm that the card supports PHP as described in "Appendix A Cards That Support PCI Hot Plug and Dynamic Reconfiguration" in the Fujitsu M10/SPARC M10 Systems PCI Card Installation Guide. For active addition combined with dynamic SR-IOV and the dynamic reconfiguration function for the PCIe end point, confirm the supported card as described in "Appendix B Cards That Support SR-IOV" and "Appendix D Cards That Support the Dynamic Reassignment Function for the PCIe End Point Device (PCIe Card)" in the same manual.
- When performing PCIe card expansion, remove the PCIe card filler from the PCIe card cassette. Store the removed filler in a safe place because it will be needed if you subsequently remove the PCIe card.
