Replacing a Mini SAS HD Cable

Replacing a Mini SAS HD Cable

This section describes how to replace a mini SAS HD 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 replacement 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 component.
  • 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 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 .


      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. Hold the mini SAS HD cable and push the connector slightly inward, as shown in Figure 12-1.

  5. Pull the mini SAS HD cable connector out of the port and put it in to an ESD bag.

  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 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 cable to facilitate subsequent operations.
