4.3.1 Precautions for Replacement


4.3.1 Precautions for Replacement
This section describes the precautions for replacement.
Precautions for XSCF Unit and XSCF Interface Unit Replacement
  1. Different XSCF units are used for the SPARC M12-2S system and the SPARC M10-4S system. (See Figure 2-2.)
  2. Before replacing an XSCF unit, execute the dumpconfig command to save the system setting information. When an XSCF unit is replaced, the CPU Activation setting information and CPU Activation keys may be deleted. To restore the CPU Activation setting information and CPU Activation keys that were saved with the dumpconfig command, execute the restoreconfig command.
    For details, see "10.10 Saving/Restoring XSCF Settings Information" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 System Operation and Administration Guide.
  3. When an XSCF unit is replaced, the system will start with the version of the firmware applied to the replacement XSCF unit. If this firmware version is different from that before replacement, the firmware is automatically updated to the pre-replacement version. However, this update takes time. To shorten the XSCF unit replacement work time, we recommend switching the microSD card mounted in the replaced XSCF unit with the card in the replacement XSCF unit. Using the microSD card from the replaced XSCF unit eliminates the need to update the firmware to the pre-replacement version.
  4. When replacing the microSD card at the same time as the XSCF unit of a crossbar box in a SPARC M10 system, do not replace them during system-stopped/cold maintenance. Doing so may put the Oracle Solaris clock greatly out of sync at system startup.
    Replace them during system-stopped/hot maintenance.
  5. If you replace the microSD card along with the XSCF unit, dispose of the microSD card mounted on the old XSCF unit by appropriate means such as cutting it with cutting pliers. The old microSD card stores the user information, IP address, and other information set in the XSCF firmware.
  6. If you use the replacefru command to replace the XSCF unit, a completion message appears when the incorporation of the XSCF unit into the crossbar box completes. However, the activation of the replaced XSCF unit firmware may not have completed by then. When you perform maintenance work on the XSCF unit, perform the next operation ten or more minutes after the incorporation completion message appears.
  7. Do not replace the XSCF unit and the XSCF interface unit at the same time during system-stopped/cold maintenance. If you replace both the XSCF unit and the XSCF interface unit at the same time, the system will fail to operate normally. Replace the XSCF unit in the hot state and then replace the XSCF interface unit in the cold state.
  8. Do not mount and use any of the following microSD cards in the XSCF unit in another chassis:
    - the one currently mounted in the crossbar box, or
    - one that was once used as a maintenance part
    This is because these microSD cards store device identification information.
  9. Do not mount and use any of the following XSCF interface units in another chassis:
    - the one currently mounted in the crossbar box, or
    - one that was once used as a maintenance part
    This is because these XSCF interface units store device identification information.
Precautions for Crossbar Cable Replacement
Caution - Do not forcibly bend the crossbar cables. A crossbar cable may be damaged if forcibly bent. Ensure that the bending radius of the crossbar cable is no less than 35 mm (1.4 in.).
  1. Replace the crossbar cables in pairs.
  2. Do not place heavy objects on the crossbar cables.
Precautions for Power Supply Unit Replacement
Caution - Do not forcibly push the power supply unit into its slot. If excessive force is applied, other components or the chassis may be damaged.
  1. There are two power supply units. Thus, the system can continue operating even if one of the units fails. However, do not operate the system for an extended period while one unit has failed.
  2. When replacing multiple power supply units, replace one unit at a time. If redundancy of the power supply unit cannot be assured, system-stopped/cold maintenance must be performed.
Precautions for Fan Unit Replacement
  1. The cooling fans have a redundant configuration. Thus, the system can continue operating even if one of the fans in the fan units experiences a failure. Avoid operating the system with a faulty fan for an extended period and replace the fan unit containing the failed fan as soon as possible.
  2. When replacing multiple fan units, replace one unit at a time. If a redundant configuration cannot be assured, perform system-stopped maintenance.
Precautions for Operation Panel Replacement
  1. To replace the operation panel, set the BB-ID of the replacement operation panel to the same value as that before replacement.
Precautions for Replacement of the Dedicated Power Distribution Unit
  1. The crossbar box is connected to the dual PDUs with power cords. Thus, the system can continue to operate even if one of the PDUs fails. However, do not operate the system for an extended period while one unit has failed.
  2. When replacing multiple dedicated power distribution units, replace one unit at a time. If redundancy of the dedicated power distribution units cannot be assured, system-stopped/cold maintenance must be performed.
