Replacing a Mini SAS HD Cable

Replacing a Mini SAS HD Cable

This section describes how to replace a mini SAS cable.

Impact on the System

When a mini SAS HD cable is being replaced, services on this cable are interrupted. Perform this operation with caution.


  • The spare part of the cable is ready.
  • You have located the component that houses the mini SAS HD cable 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 position.
  • Data has been backed up before you replace the cable online.


Use even force when you remove or insert a mini SAS HD cable. Excessive force may damage the appearance or connector of the mini SAS HD cable.

Tools and Materials

  • ESD wrist strap
  • ESD bags
  • Labels


  1. Check status before replacement.


    Only for OceanStor 18000 and 18000F series storage systems, mini SAS HD cables can be replaced using SmartKit. For other models of storage systems, skip 1 and 9.

    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 some items fail in 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. Hold the mini SAS HD cable and push the connector slightly inward, as shown in Figure 6-104.

  4. Hold the plastic ring and pull it outward along the arrow direction until the mini SAS HD cable is unlocked, as shown in Figure 6-105 and Figure 6-106.

  5. Pull the mini SAS HD cable connector out of the port and put it in to an ESD bag.
  6. Take the replacement mini SAS HD cable out of the ESD bag.
  7. Insert the replacement mini SAS HD cable vertically into the original position, as shown in Figure 6-107.

  8. View the Port indicator, and determine whether the installation is successful.

    • If the indicator is steady green or blue, the cable is successfully installed.
    • If the indicator is steady red or off, the newly installed cable is faulty, the cable slot is faulty, or the cable is incorrectly installed.

  9. Confirm the replacement.

    1. Perform a post-replacement inspection.

      After the parts replacement, return to the SmartKit page and click Replaced. Then complete the parts 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 inspection item fails, rectify the fault based on the suggestions.

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

Follow-up Procedure

Label the replaced cable to facilitate subsequent operations.
