7.1 Precautions for FRU Replacement


7.1 Precautions for FRU Replacement
This section describes the precautions for FRU replacement.
When replacing a FRU, replace it with a part with the same part number or a succeeding part.
Precautions for XSCFU and PSUBP replacement
  1. You can perform active replacement of the XSCFU only in the SPARC M12-2S in a multiple-BB configuration.
  2. Do not replace the XSCFU and the PSUBP at the same time. If the XSCFU and the PSUBP are replaced at the same time, the system may fail to operate normally.
  3. Do not mount and use any of the following SD cards in the XSCFU in another chassis:
    - the one currently mounted in the SPARC M12-2/M12-2S, or

    - one that was once used as a maintenance part

    This is because these SD cards store device identification information.
  4. Do not mount and use any of the following PSUBP in another chassis:
    - the one currently mounted in the SPARC M12-2/M12-2S, or

    - one that was once used as a maintenance part

    This is because the above PSUBP stores device identification information.
  5. Before replacing the XSCFU, confirm that the READY LED of the target XSCF is lit in green or off. If the READY LED of the XSCF is blinking, wait until the LED stays lit or is turned off.
  6. You cannot replace the master XSCFU. To replace it, switch the master, or remove the power cords of all the BBs.
  7. If you select the XSCFU in the replacefru command menu, you cannot remove the XSCF DUAL control cable, XSCF BB control cable, or power cord. The only unit that you can remove is the XSCFU.
  8. During the XSCFU replacement, do not configure the various settings of XSCF reboot, master switching, firmware update, physical partition power-on/power-off/reset, and the XSCF. If any of these processes is in progress, wait for the process to complete before replacing the XSCFU.
  9. During the active replacement of the XSCFU, the ldm command may cause an error in the control domain where the replacement is performed. Retry after the replacement of the XSCFU is complete. After the replacement is complete, check that the ldmd service in the control domain is running normally.
Precautions for CMU and memory replacement
Caution - Remove the PCICS before removing the CMUL. Replacing the CMUL with the PCICS installed may damage the PCICS or CMUL.
Caution - Before removing the CMUL or CMUU, bundle the PCIe cables of the CMUU in the specified procedure. Removing the CMUL or CMUU without bundling the PCIe cables may damage the CMUL or CMUU.
For details, see "Chapter 17 Maintaining the CPU Memory Unit and Memory."
Caution - Remove the XBU before removing the CMUL or CMUU from the SPARC M12-2S. Replacing the CMUL or CMUU with the XBU installed may damage the CMUL/CMUU or XBU.
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. When remounting memory during the replacement of the CMUL/CMUU or memory, be sure to remount a memory module of the same capacity and the same rank at the same location as before.
  1. If you have replaced the CMUL that has the hardware RAID function enabled, re-enable the hardware RAID volume.
    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.
Precautions for PSU replacement
Caution - When mounting a PSU in the BPU, make sure that the PSU is oriented so that its power connector is on the left side. Mounting a PSU in the wrong orientation may damage the BPU or PSUBP.
  1. The power control of the SPARC M12 has a redundant configuration so that the system will continue to run even if one PSU fails. However, avoid running the system for a long time in a faulty condition. Replace the failed PSU.
  1. When there are multiple PSUs to replace, replace them one by one. If redundancy of the PSUs cannot be secured, system-stopped replacement must be performed.
Precautions for FANU replacement
Caution - Do not forcibly push the FANU when mounting it in the FANBPU. When mounting the FANU, push it at two points at the bottom of its front side. Pushing any points other than the specified ones when mounting the FANU may damage the FANU or FANBPU.
  1. The cooling fan of the SPARC M12 has a redundant configuration so that the system will continue to run even if one cooling fan of a FANU fails. However, avoid running the system for a long time with a cooling fan failed. Replace the FANU with the failed fan.
  1. When there are multiple FANUs to replace, replace them one by one. If redundancy of the FANUs cannot be secured, system-stopped replacement must be performed.
Precautions for FANBPU replacement
  1. Be sure to remove all the FANUs from the FANBPU before removing the FANBPU.
Precautions for HDD/SSD replacement
  1. When the RAID volume is configured by software, the configuration may need to be changed on the software before and after the replacement of the HDD/SSD. Before starting the work, be sure to see the user manual for the software being used.
Precautions for PCIe card replacement
  1. To perform active replacement of a PCIe card, the PCIe to be replaced must support PCI Hot Plug. Before performing active replacement, see "Appendix B Cards That Support PCI Hot Plug and Dynamic Reconfiguration" in the Fujitsu SPARC M12 PCI Card Installation Guide.
  2. Before performing active replacement of a PCIe card having a multipath I/O 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.
  3. 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.
  1. 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.
