Replacing an Optical Module

Replacing an Optical Module

This section describes how to replace an optical module.

Impact on the System



  • The replacement optical module is ready.
  • You have located the interface module that houses the optical module you want to replace.
    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.


  • Remove and insert an optical module with even force. Excessive force may damage the appearance or connectors of the optical module.
  • Do not frequently or quickly remove or insert an optical module; otherwise, it may be damaged.
  • If you want to replace the optical module (which has four links) on an 8 Gbit/s FC interface module (eight ports), ensure that all working links have backup links. You are advised to disable the ports of the switch that connect to the 8 Gbit/s FC interface module (eight ports) and switch the services from these ports to the backup links to avoid interruption during the replacement.

Tools and Materials

  • ESD wrist strap
  • ESD bag
  • 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.
  3. Remove the optical fibers connected to the optical module to be replaced.

    Do not look into the optical port without eye protection. The laser beam on the optical interface board or from the fiber may cause injuries to eyes.

  4. Open the latch of the optical module, and pull out the optical module, as shown in Figure 8-1.

  5. Put the removed optical module into an ESD bag.
  6. Take the replacement optical module out of its ESD bag.
  7. Remove the protective cap from the optical module, and insert the optical module into the port, as shown in Figure 8-2.

    • Before inserting an optical module, ensure that its latches are completely closed.
    • Insert the optical module to the enclosure until you hear a "click" sound or feel a slight shake, which indicates that the optical module is inserted in place.
    • If the optical module is not inserted in place, it will fall out or will cause a link fault.

  8. Insert the optical fibers into the optical module.

    Do not look into the optical port without eye protection. The laser beam on the optical interface board or from the fiber may cause injuries to eyes.


    Insert the optical fibers until they snap into place.

  9. Observe the port indicator to check whether the optical module is properly installed.

    • If the indicator is steady green or blue, the installation is successful.
    • If the indicator is steady red or off, the newly installed optical module is faulty, the port for the optical module is faulty, or the optical module is incorrectly installed.

  10. 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

Label the replaced optical module to facilitate subsequent operations.
