Remove a Data Cable

Removing a single data cable is a hot-swap operation. If you are removing all data cables as part of a switch replacement, the switch must be powered off.

This task describes how to remove the cables from the switch, so that the cable can be replaced. If you are removing all cables for switch replacement, start removing the cables from the left side of the switch, working your way to the right.

Note -  These instructions are valid for both IB and Ethernet data cables.
  1. Determine which data cable to remove.

    See Locate a Faulty Data Cable.

  2. Consider your next step.
    • If you have not prepared for service, you must do so now.

      See Preparing for Service.

    • If you have completed those prerequisite tasks, go to Step 3.
  3. Loosen the thumbscrews and remove the cover for the CMB.

  4. Locate the cable to be removed.
  5. (Optional) If necessary, label that cable so that its corresponding port, its peer, or both, are identified.
  6. Consider your next steps.

    If you are removing all cables for switch replacement, start with the PrizmMT cables.

    • If you are removing a PrizmMT cable, go to Step 7.
    • If you are removing a one-piece copper core SFP+ cable, go to Step 8.
    • If you are removing an assembled fiber optic SFP+ cable, go to Step 9.
    • If you are removing an RJ-45 cable, go to Step 10.
  7. Remove a PrizmMT cable.
    1. Pinch the PrizmMT cable connector housing between your thumb and forefinger.

      The housing is either magenta or black colored.

    2. With a steady force, pull the PrizmMT connector straight out of the receptacle.
    3. Go to Step 11.
  8. Remove a one-piece copper core SFP+ cable.
    1. Grasp the cable connector to support its weight, and apply the removal force.
    2. Pull on the retractor strap while simultaneously pulling on the cable connector.

      The cable connector comes free.

    3. Go to Step 11.
  9. Remove an assembled fiber optic SFP+ cable.
    1. Press the release tab on the LC connector and pull back.

      The LC connector and fiber optic cable come free of the transceiver.

    2. Release the latch on the SFP+ transceiver and pull on the latch to remove the transceiver.
      image:Illustration shows the transceiver being removed.

      The transceiver comes free.

    3. Set the transceiver aside.
    4. Go to Step 11.
  10. Remove an RJ-45 cable.
    1. Pinch the top and bottom of the RJ-45 connector between your thumb and forefinger.

      Use either your thumb or forefinger to depress the release tab.

    2. Pull the RJ-45 connector straight out of the receptacle.
  11. Carefully move the cable out of the CMB.
  12. Cap the end of the cable if possible.
  13. Repeat Step 4 and Step 12 for any additional cables to be removed.
  14. Consider your next steps.
    • If you removed a data cable as part of a replacement operation, disconnect the other end of the cable, and install a new data cable.

      See Install a Data Cable.

    • If you removed all of the data cables for switch removal task, do that now.

      See Remove the Switch.

    • If you are not replacing the data cable, go to Step 15.
  15. If you removed a PrizmMT cable, put a filler plug into that receptacle.
  16. Replace the cover for the CMB and tighten the thumbscrews.
