Replacing a Management Module

Impact on the System

During the replacement of a management module, the service processing capability is adversely affected.

Prerequisites

• The spare part is on hand.
• The management module that you want to replace has been located.

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

  • Locating a component based on alarms in DeviceManager: On the Alarms and Events page of DeviceManager, view the help information and determine the ID of the component to be replaced. Then locate the component at your site based on its ID.
  • Locating a component based on the status of its Running/Alarm indicator: For details about the indicators on different components, see "Indicator Introduction" of each component in the Product Description specific to your product model and version.

• The cable connection positions of the management module that you want to replace have been labeled on the cables.

Precautions

• You are advised to replace one management module at a time.
• Remove and insert a management module with even force. Excessive force may damage the appearance of the management module or cause faults.
• A management module must be replaced within five minutes. Otherwise, the system heat dissipation is compromised.
• After removing a management module, wait at least 15 seconds before inserting one.

Tools and Materials

• ESD wrist strap
• ESD bag
• Labels

Procedure

1. Perform a pre-replacement check.
   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.

      If any 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 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. Remove the cables from the management module that you want to replace.
4. Press the latch to release the handle of the management module and pull out the management module, as shown in Figure 7-117.
   Figure 7-117 Removing the management module
   

5. Put the removed management module into an ESD bag.
6. Take the spare part out of its ESD bag.
7. Insert the spare part into the empty slot until it clicks into place, as shown in Figure 7-118.

8. Connect the cables as labeled.
9. Wait about two minutes and check the status of the Power indicator on the management module to determine whether the management module has been successfully installed. Figure 7-119 shows the location of the Power indicator.
   • If the indicator is steady green, the management module has been successfully installed.
   • If the indicator is steady yellow or off, the newly installed management module is faulty, the management module slot is faulty, or the management module is incorrectly installed.

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

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

    2. Check system status.

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

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

Follow-up Procedure

After the management module is replaced, label it to facilitate subsequent operations.
