Remove a Data Cable

This procedure describes how to remove the cables from the switch chassis, so that a cable can be replaced. If you are removing all cables for switch replacement, label each cable with its socket number, then start removing the cables from the left side of the switch, working your way to the right.

1. If the switch has a CMA, loosen two thumbscrews to remove the CMA cover.
   
2. Locate the cable to be removed.
3. Grasp the cable connector to support its weight and apply the removal force.
4. Disconnect the cable from the connector.
   • For a dual-part QSFP+ cable assembly, pull the optical cable connector retraction handle and gently pull out the optical cable.
   • For a single-part passive copper QSFP+ cable, pull on the retractor strap while simultaneously pulling on the cable connector.
5. Carefully move the cable out of the cable management hardware.
6. Gently lower the cable to the floor.

   Caution  - Do not allow the cable to drop or strike the floor. Jerking, bending, pulling on, or dropping the cable can damage the cable.

7. For a dual-part QSFP+ module assembly, remove the optical transceiver module from the slot.
   1. Replace the protective end cap if you plan to store the module.
   2. Slide out the optical transceiver module.
   3. Replace the protective end cap if you plan to store the module.
8. Consider your next step:
   • If you are removing a single cable for replacement, install the new cable.

     See Install a Data Cable.

   • If you are disconnecting all cables for switch replacement, repeat from Step 2 for all cables.
