Replacing a System Subrack

Replacing a System Subrack

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.


  • A replacement system subrack is ready.
  • The system subrack that you want to replace has been located.
    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 component.
  • The cable connection positions of the system subrack that you want to replace are labeled on the cables.
  • Services running on the system subrack that you want to replace have been stopped.
  • Before replacing a system subrack, you need to power off the storage system.
    For details about how to power on or off a storage system, see corresponding sections in the Administrator Guide.


  • Remove and insert a system subrack with even force. Excessive force may damage the appearance or connectors of the system enclosure.
  • To prevent personal injury, arrange three persons to move a fully configured system subrack.

Tools and Materials

  • Phillips screwdrivers (M3 to M6)
  • ESD wrist strap
  • ESD bag
  • ESD table
  • Labels
  • Product model bar
  • Optional: Nameplate
  • Optional: Intel label
  • Optional: Device information label


  1. Check system status before replacement.
    1. Perform a system status inspection.

      Start SmartKit. On the homepage, choose MyTools > Storage > Parts Replacement > Inspection. The Inspection Wizard step 5-1:Welcome page is displayed after you go to the Inspection page. On the wizard, select Routine inspection and perform the inspection as instructed by the wizard.

      For details, you can click .


      If some items fail 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 correctly.

    2. Perform a pre-replacement inspection.

      On the homepage, choose MyTools > Storage > Parts Replacement > FRU Replacement. On the FRU Replacement page, select the part that you want to replace and perform the pre-replacement inspection as prompted. For details, see Using SmartKit for Parts Replacement (Recommended).

      You can proceed to next step only when all items pass the pre-replacement check and the replacement page is displayed. If any item fails, rectify the fault by taking recommended actions in the inspection reports.

  2. Wear an ESD wrist strap and remove all the cables from the system subrack that you want to replace.
  3. Take the replacement system subrack out of its ESD bag and place it on the ESD table.
  4. Insert the product model bar into the upper part of the system subrack. The arrow in Figure 4-30 shows the installation position of the product model bar.

    Figure 4-30  Position of the product model bar


    Multiple different product model bars are often included in the product. Please select the one that contains identical information to the product model bar on the removed system enclosure.

  5. Remove components from the system subrack that you want to replace and reinstall them to their original positions in the replacement system subrack.
  6. Remove the system subrack that you want to replace from the cabinet, as shown in Figure 4-31.
    1. Open the mounting ear cover. Use a Phillips screwdriver to remove the M6 screws from the system subrack.
    2. Pull the system subrack out of the cabinet along guide rails and place it on the ESD table.

  7. Optional: Attach the nameplate and the Intel label to the same positions on the replacement system subrack as those on the removed system subrack, as shown in Figure 4-32. a indicates the nameplate location, and b indicates the Intel label location.

    Figure 4-32  Positions of the nameplate and Intel label


    Two different nameplates are often included in the product. Please select the one that contains identical information to the nameplate on the removed system subrack.

  8. Optional: Pull the information plate of the system subrack. (If you face the front part of the system subrack, the information plate is located at the lower right of the enclosure, as shown in Figure 4-33. Gently pull the information plate, but not away from the enclosure.) Attach the device information label to the information plate. After that, push the information plate back to the enclosure.

    Figure 4-33  Position of the information plate


    You can attach the device information labels to both the front or back of the information plate. The installation positions must be the same as those on the replacement system subrack. If a label has been attached to one side of the information plate, you only need to attach the device information label with a QR code to the other side of the information plate. Attaching the device information plate helps engineers more easily identify and maintain devices.

  9. Install the replacement system subrack into the cabinet, as shown in Figure 4-34.
    1. Slide the system subrack into the cabinet along guide rails.
    2. Use M6 screws to fix the system subrack in the cabinet. Close the mounting ear cover.
    3. Ensure that the system subrack is horizontally installed and tightly screwed.

  10. Connect cables to the system subrack and press the Power button to power on the storage device.
  11. When the Power indicator is steady on, check whether each component is in normal state.

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

  12. Confirm the replacement.
    1. Perform a post-replacement inspection.

      After the replacement, on the SmartKit page, click Replaced. Perform the post-replacement inspection as prompted.

    2. Check the system status after the replacement.

      Check the system status again on the Inspection page after the replacement. If any inspection item fails, rectify the fault based on the suggestions.

    3. Check services on a host for any storage-related error.

Follow-up Procedure

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