Replacing an Optical Module (Applicable to 8 Gbit/s Fibre Channel Interface Module (Eight Ports))

Replacing an Optical Module (Applicable to 8 Gbit/s Fibre Channel Interface Module (Eight Ports))

This section describes how to replace an optical module.

Impact on the System

During the replacement of an optical module, the system switches services from this module (4 array ports) to other ports on this controller or on the peer controller. If available links are unable to bear the current service load, host latency increases and the system performance degrades. If there are no other redundant links, services carried by the optical module will be interrupted.

Prerequisites

  • The replacement spare parts are ready.
  • The optical module that you want to replace has been located.

Precaution

  • Use even force when you remove or insert an optical module. Excessive force may damage the appearance or connector of the optical module.
  • To prevent an optical module from damage, do not remove and insert an optical module quickly or frequently.
  • There are four links connecting to an optical module. If you want to replace the 8 Gbit/s Fibre Channel 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 Fibre Channel interface module (eight ports) and switch the services on these ports to backup links to avoid interruption during the replacement.

Tools and Materials

  • ESD wrist strap
  • ESD bag
  • Label

Procedure

  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 .

      NOTE:
      Wait until the inspection is complete. If any inspection item fails, rectify the fault based on the suggestions. Ensure that all system components run correctly except for the part to be replaced.

    2. Check redundant paths to the host.

      For details, see Checking the Multipathing Status in the Performance Monitoring Guide.

      Contact Huawei technical support for parts replacement to prevent data damage caused by accidents during the replacement.

      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. Grip the green part of the optical fiber, remove the MPO end of the optical fiber from the optical module, and cover the optical fiber with a dustproof cap, as shown in Figure 10-1.

    Do not look into the optical port without eye protection. The laser beams inside an optical port can cause damage to your eyes.

  4. Grip the rubber handle outside the optical module, pull the optical module out with even force, and cover it with a dustproof cap, as shown in Figure 10-2.

    Figure 10-2  Removing the optical module

  5. Put the removed optical module into an ESD bag.
  6. Take a spare optical module out of its ESD bag.
  7. Take the dustproof cap off the optical module, hold the rubber handle outside the transceiver, and insert the transceiver into the port, as shown in Figure 10-3.

    • Push the optical module to the end. If you hear the click or feel a weak vibration, the optical module is successfully installed.
    • If an optical module is installed incorrectly, it will loose or a link interruption may occur.

  8. Take off the dustproof cap. Point the white dot of the optical fiber downward and insert it directly to the optical module. Grip the black connector and push it forward until you hear the click or feel the vibration, as shown in Figure 10-4.

    Do not look into the optical port without eye protection. The laser beams inside an optical port can cause damage to your eyes.

  9. View the port indicator, and determine whether the installation is successful.

    • If the indicator is steady green or blue, the optical module is successfully installed.
    • If the indicator is steady red or off, the newly installed optical module is faulty, the slot that houses the transceiver 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.
