Replacing a System Subrack (High-Density Disk Enclosure)

Replacing a System Subrack (High-Density Disk Enclosure)

This section describes how to replace a system subrack.

Impact on the System

Replacing a system subrack interrupts services running on the system subrack. Exercise caution when performing this operation.

Prerequisites

  • The spare part of the system subrack is ready.
  • The system subrack that you want to replace has been located.
NOTE:

You can locate a component in either of the following ways:

  • Log in to DeviceManager and go to the System page. On the System page, check the device view and locate the position of the component to be replaced. If the component has a location indicator, turn on the indicator. (For details about how to turn on a location indicator, see the online help of DeviceManager.)
  • Use the alarm indicator of the component to locate its position.
  • The installation positions of the cables connecting to the system subrack that you want to replace have been clearly marked.
  • Services running on the system subrack that you want to replace have been stopped.
  • The power cables have been disconnected from the system subrack that you want to replace.

Precautions

  • To avoid personal injury, arrange three persons to move a system subrack.

Tools and Materials

  • Phillips screwdriver (M3 to M6)
  • ESD wrist strap
  • ESD bag
  • ESD table
  • Diagonal pliers
  • Cable tie
  • Label
  • Protective gloves

Procedure

  1. Check status before replacement.

    1. Check system status.

      Start SmartKit and choose Home > Storage > Routine Maintenance > Health Check. On the Health Check page, perform inspection as instructed. For details, see Checking System Status.

      NOTE:

      If some items fail in the inspection, rectify the faults by performing the recommended actions in the inspection reports. Ensure that all other parts except the parts to be replaced are working properly.

    2. Check the status of the parts to be replaced.

      Start SmartKit and choose Home > Storage > Parts Replacement > Parts Replacement. On the Parts Replacement page, click FRU Replacement. Then complete the check before the replacement as prompted. For details, see Replacing an FRU.

    You can proceed to next steps only when all items pass the pre-replacement check and the replacement page is displayed. If any item fails, rectify the fault as prompted.

  2. Wear an ESD wrist strap.
  3. Uninstall cable trays and disconnect cables from the system subrack.
  4. Take the replacement system subrack out of its ESD bag and place it on the ESD table.
  5. Remove all smart disk modules, power modules, fan modules, and switch board modules from the system subrack that you want to replace and place them on the ESD table.

    Record the slots of all components. Install these components into the same slots as in the system subrack that you want to replace. Otherwise, system services may be affected.

  6. Remove the system subrack that you want to replace from the cabinet.

    1. Loosen the two screws on the panel and pull out the enclosure slowly, as shown in Figure 6-17.

    3. Press the retention clips on ball bearing guide rails, pull out the system subrack, and place the system subrack on the ESD table, as shown in Figure 6-19.

  7. Uninstall the inner guide rails on the system subrack that you want to replace and reinstall them to the same positions on the replacement system subrack.

    1. Use a Phillips screwdriver to loosen the four screws on the inner guide rails, as shown in Figure 6-20.

  8. Install the system subrack into the cabinet.

    1. Slide the system subrack into the cabinet along guide rails.
    2. Loosen the two screws on the panel and slowly pull out the enclosure, as shown in Figure 6-24.

    5. Verify that the system subrack is horizontally installed.
    6. Install all the components into the newly installed system subrack.

    Install all components in the same slots as in the removed system subrack. Otherwise, system services may be affected.

  9. Install cable trays and connect the cables of the system subrack.
  10. When the Power indicator is steady on, check whether the components are running correctly when the Power indicator is steady on.

    • If yes, the installation is successful.
    • If no, cables or components are incorrectly connected, or the newly installed system subrack is faulty.

  11. Confirm the replacement.

    1. Perform a post-replacement inspection.

      After the parts replacement, return to the SmartKit page and click Replaced. Then complete the parts check after the replacement as prompted.

      NOTE:

      If the 0xF00CE002A and 0xF00D00016 alarms are generated and contain the SN of the faulty system subrack that has been replaced, check the device configuration according to the alarm information. If the configuration is correct, log in to DeviceManager to manually clear the alarms, return to the SmartKit page, and click Recheck.

    2. Check system status.

      On the Parts Replacement page, click Inspection to check the system status again. If any inspection item fails, rectify the fault based on the suggestions.

    3. After the preceding procedure is complete, check services on the host for any storage-related error.

Follow-up Procedure

After the system subrack is replaced, label it to facilitate subsequent operations.
