Install the cable management arm

The cable management arm allows the server to be fully extended from the rack without the need to power off the system or disconnect any rear panel cables. This CMA is designed for ambidextrous implementation.

CAUTION: Support the CMA during the installation. Do not allow the CMA to hang by its own weight until it is secured from all three connection points.
Procedure
  1. Connect all peripheral cables and power cords to the rear panel.
  2. Install the CMA:
    1. Fasten the inner retention connector to left sliding rail hook.
    2. Fasten the outer retention connector to left mounting rail hook.
    3. Fasten the hinged connector to right mounting rail hook.

    Employ industry best practices in routing and managing these rear panel cables and power cords.

  5. Verify the operation of the rack rails and the CMA:

    Two people might be needed for this procedure: one to slide the server tray in and out of the rack, and the other to observe the cables and CMA.

    1. Fully extend the server tray out of the rack.
    2. Check that there is enough slack in the cables and cords to allow for full extension of the CMA without any cable binding or crimping.
    3. Slide the server tray in and out of the rack to make sure that the cables and the CMA are working properly.
  6. Press and hold the blue rail-release tabs, and then slide the tray back into the rack.
