7.3 Precautions for FRU Reduction
This section describes the precautions for FRU reduction.
Before performing reduction work, see "(3) Checking the FRU status" in "8.2.2 Identifying a Fault" to confirm that there is no problem with the chassis requiring reduction.
Precautions for CMUU removal
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.
Caution - Be sure to remove the XBU before removing the CMUU from the SPARC M12-2S. Replacing the CMUU with the XBU installed may damage the CMUU or XBU.
Caution - Be sure to bundle PCIe cables in the specified procedure before removing the CMUU. Removing the CMUU without bundling PCIe cables may damage those PCIe cables. For details on the procedure, see "Chapter 17 Maintaining the CPU Memory Unit and Memory."
  1. To operate the system with the CMUU removed, mount the stored CMU filler unit after removing the CMUU. Not using the CMU filler unit hinders chassis cooling, resulting in unstable system operation.
  2. If the CMUU in the following system or state is removed, a root complex is also removed and some PCIe slots become unusable:
    - System with a CPU configuration expanded from one CPU at initial installation to two CPUs and with the I/O bus reconfigured

    - State where the I/O bus reconfiguration function is disabled on a system with a CPU configuration of two CPUs at initial installation

    To use all the PCI slots, enable the I/O bus reconfiguration function and change the I/O device path. However, you may need to reconfigure the logical domains because the I/O device path changes.
Precautions for memory reduction
Caution - The CMUU weighs 10 kg (22 lb), and the CMUL weighs 13 kg (29 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.
  1. In memory reduction, observe the memory installation rules. For details, see "2.2.1 Memory Installation Rules."
  2. When reducing memory, you may need to reconfigure the logical domains.
    For details, see "3.2.14 Configuring Virtual Memory" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 Domain Configuration Guide.
Precautions for HDD/SSD removal
  1. When removing the HDD/SSD, mount the filler unit in the empty slot.
Precautions for PCIe card removal
  1. When using the PCI Hot Plug function for active removal of a PCIe card having a multipath setting, you may need to release the target PCIe card from the multipath configuration. See the manual for the multipath software being used.
  2. When performing active removal using PCI Hot Plug, confirm that the PCIe card supports PCI Hot Plug. For details, see "Appendix B Cards That Support PCI Hot Plug and Dynamic Reconfiguration" in the Fujitsu SPARC M12 PCI Card Installation Guide.
  3. To perform active removal in combination with the dynamic SR-IOV function or the dynamic reconfiguration function for a PCIE endpoint, confirm that the card supports the respective function. 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 M12 PCI Card Installation Guide.
  4. After removing the PCIe card, install a PCIe card filler in the PCICS and then mount the PCICS in the SPARC M12-2/M12-2S.
Precautions for SPARC M12-2S removal
  1. To remove a SPARC M12-2S from a building block configuration, use a method other than system-stopped/cold removal. Performing system-stopped/cold removal for a SPARC M12-2S may make the removed SPARC M12-2S unusable.
  2. The SPARC M12-2S removed from a building block configuration has the XSCF settings information initialized. To use the removed SPARC M12-2S for another system, initialize the BB-ID and other settings beforehand.
  3. Suppose you remove a SPARC M12-2S from a building block configuration to use it for another system. In that case, delete as many CPU Activation keys from the original building block configuration as the number of CPU Activations to be used in the other system, and then register these CPU Activation keys in the new system.
