Replacing a Cable

Replacing a Cable

This section describes how to replace a cable.

Impact on the System

Replacing a cable may interrupt system services. Replace the cable in off-peak hours and back up data in advance to avoid unexpected service interruption.


  • The replacement cable is ready.
  • The cable that you want to replace has been located.
  • Data has been backed up if you replace the cable online.


Remove and insert a cable with even force. Excessive force may damage the cable.

Tools and Materials

  • ESD wrist strap
  • ESD bag
  • Label


  1. Wear an ESD wrist strap.
  2. Confirm the position of the cable to be replaced and record the cable's label.
  3. Cut the binding tapes and remove the cable to be placed.

    Do not look into the optical port without eye protection. The laser beams inside an optical port can cause damage to your eyes.


    Before removing a SAS cable, gently push the connector of the cable inward. Then pull the plastic ring on the connector outward and hold the plastic ring while removing the cable.

  4. Put the removed cable into an ESD bag.
  5. Take the replacement cable out of the ESD bag.
  6. Write the content recorded in 2 to a new label and attach the new label to the cable to be installed.
  7. Insert the replacement cable to the position of the original cable.

    If various cables at different locations have been replaced simultaneously, ensure that the cables before and after the replacement have the same types.

    Do not look into the optical port without eye protection. The laser beams inside an optical port can cause damage to your eyes.

  8. Optional: View the indicator of the cable port, and determine whether the installation is successful if you replace the cable online.


    Indicator colors vary with different interface modules. In general, a red indicator indicates that the system has an alarm or is abnormal. For details, refer to the Product Description.

  9. Bind the cables.
  10. 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 cable is replaced, label it for subsequent operations.
