Replacing a Fan Module (for OceanStor 18500 V5, 18500F V5, 18800 V5, or 18800F V5)

Prerequisites

• The spare part is on hand.
• The fan 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.

Precautions

• Do not touch rotating fan blades.
• Remove and insert a fan module with even force. Excessive force may damage the appearance of the fan module or cause faults.
• A fan module must be replaced within three minutes. Otherwise, the system heat dissipation is compromised.
• Remove only one fan module at a time.
• To avoid the sharp increase of the system temperature, replace only faulty fan modules.

Tools and Materials

• ESD table
• ESD wrist strap
• ESD bag
• Labels

Procedure

1. Check status before replacement.
   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. Press the latch on the fan module to release the handle and pull out the fan module, as shown in Figure 8-105.

4. Put the removed fan module into an ESD bag.
5. Take the spare part out of its ESD bag.
6. Insert the spare part into the empty slot, as shown in Figure 8-106.
   Figure 8-106 Installing the fan module
   

7. Wait about two minutes and check the status of the Running/Alarm indicator on the fan module to determine whether the fan module has been successfully installed, as shown in Figure 8-107.
   • If the indicator is steady green, the fan module has been successfully installed.
   • If the indicator is steady yellow or off, the newly installed fan module is faulty, the fan module slot is faulty, or the fan module is incorrectly installed.

8. 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 fan module is replaced, label it to facilitate subsequent operations.
