Replacing an Interface Module

Replacing an Interface Module

This section describes how to replace an interface module.

Impact on the System

During the replacement of an interface module, the system switches services from ports on this module to ports on another module of the local controller or the peer-end 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 run on a single link and the system reliability degrades.

Prerequisites

  • The new interface module must be of the same type as the one to be replaced. If you want to use a different type of interface module, you must contact Huawei technical support.
  • The replacement interface module is ready.
  • The interface module 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 component.
  • The cable connection positions of the interface module that you want to replace are labeled on the cables. This requirement does not apply to interface modules (such as the Smart ACC module) that do not need cable connections.

Precaution

  • If the interface module to be replaced is a SmartIO interface module, remove the optical module from the interface module and insert a new SmartIO interface module into the controller enclosure. After the power indicator of the new interface module is steady green, wait for 2 minutes and do not remove or insert any optical module within this period. Then insert the removed optical module into the new SmartIO interface module.
  • Remove and insert an interface module with even force. Excessive force may damage the appearance or connectors of the interface module.
  • An interface module must be replaced within five minutes. Otherwise, the system heat dissipation is compromised.
  • After removing an interface module, wait at least fifteen seconds before inserting one. Otherwise, the system cannot identify the status change of the interface module.
  • Cable removal and insertion are not required for interface modules (such as the Smart ACC module) that do not need cable connections.
  • If you replace an interface module that uses Ethernet protocol with one that uses Fibre Channel protocol, the Ethernet port configuration information will be deleted, and VLANs, logical ports, and bonded ports on the original interface module will become unavailable. If you replace the interface module again with one that uses Ethernet protocol, the Ethernet port configuration information will not restore, but the VLANs, logical ports, and bonded ports on the Ethernet interface module will.
  • If you replace an interface module that uses Fibre Channel protocol with one that uses Ethernet protocol, the Fibre Channel port configuration information will be deleted. If you replace the interface module again with one that uses Fibre Channel protocol, the Fibre Channel port configuration information will not restore.

Tools and Materials

  • ESD wrist strap
  • ESD bag
  • Labels

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:

      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. Optional: Check the status of the Power indicator/Hot Swap button on the interface module to determine whether the interface module is successfully powered off, as shown in Figure 4-23.

    • If the indicator is off, the interface module is successfully powered off, skip to 4.
    • If the indicator is on, use a paper clip or a similar object to press the Power indicator/Hot swap button on the interface module to power off the interface module.

  4. Remove the cables from the interface module that you want to replace.
  5. Press the latch on the interface module and pull out the interface module, as shown in Figure 4-24.

  6. Put the removed interface module into an ESD bag.
  7. Take the replacement interface module out of its ESD bag.
  8. Insert the replacement interface module into the empty slot until it clicks into place, as shown in Figure 4-25.

  9. Connect the cables.

    The cable connection positions of the new interface module must be identical to those of the original interface module, in case service operation will be affected.

    NOTE:

    In the case of a Fibre Channel, FCoE, Smart IO, or IB interface module, it is recommended that the cables be connected four minutes after the module installation to prevent any impact on the status update of the interface module.

  10. Wait about two minutes and check the status of the Power indicator on the interface module to determine whether the interface module is successfully installed. Figure 4-26 shows the location of the Power indicator.

    • If the indicator is steady green, the fan module is successfully installed.
    • If the indicator is steady red or off, the newly installed interface module is faulty, the interface module slot is faulty, or the interface module is incorrectly installed.

  11. 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 interface module is replaced, label it to facilitate subsequent operations.
