Oracle^® Servers X7-2 and X7-2L Installation Guide

Remove the Cable Management Arm

Follow this procedure to remove the cable management arm (CMA).

Before you begin this procedure, refer to the illustration provided in Step 1 in the procedure Install the Cable Management Arm (Optional) to identify CMA connectors A, B, C, and D. Disconnect the CMA connectors in the reverse order in which you installed them, that is, disconnect connector D first, then C, then B, and finally A.

Throughout this procedure, after you disconnect any of the CMA four connectors, do not allow the CMA to hang under its own weight.

1. To prevent the rack from tipping forward when the server is extended, ensure that the rack anti-tilt bar is extended.

   ---

   Caution  -  To reduce the risk of personal injury, stabilize the rack cabinet and extend the anti-tilt bar before extending the server from the rack.

   ---

   For instructions to stabilize the rack, see Stabilize the Rack.

2. To make it easier to remove the CMA, extend the server approximately 13 cm (5 inches) out of the front of the rack.
3. To remove the cables from the CMA:
   1. Disconnect all cables from the back of the server.
   2. If applicable, remove any additional Velcro straps that were installed to bundle the cables.
   3. Unwrap the six Velcro straps that are securing the cables.
   4. Open the three cable covers to the fully opened position.
   5. Remove the cables from the CMA and set them aside.
4. To disconnect connector D:
   1. Press the green release tab (callout 1) on the slide-rail latching bracket toward the left and slide the connector D out of the left slide-rail [frames 1 and 2].

      When you slide connector D out of the left slide-rail, the slide-rail latching bracket portion of the connector remains in place. You will disconnect it in the next step.

      ---

      Note -  After you disconnect connector D, do not allow the CMA to hang under its own weight. Throughout the remainder of this procedure, the CMA must be supported until all the remaining connectors are disconnected and the CMA can be placed on a flat surface.
