Right-Side Mounting Instructions

1. Install the CMA on the rear right side of the rails by attaching both CMA housings to the

attachment brackets on the rails.

2. Route the cables through the CMA while avoiding twisting the cables. Use the hook and loop

straps on the CMA to secure the cables.

3. If the cable bundle includes a keyboard, video, and mouse (KVM) dongle, the cable may be too

short for the dongle to be placed in the CMA basket. Route the remainder of the cable beyond
the dongle through the CMA. DO NOT secure the dongle to the outside of the CMA as this may
restrict the ability of the CMA to support full extension of the rails without causing damage to the
dongle. See Figure 5.

4. Once you have routed all the cables through the CMA, dress the cable slack between the back of

the system and the entrance of the CMA using the tie wraps (shown in yellow in all illustrations)
provided in the CMA kit.

5. Clip off the excess length of material from the tie wraps. Make sure that the heads of the tie wraps

are positioned so as to avoid interference with adjacent systems. Return the CMA to the closed
(retracted) position.


Extend the system out of the rack to verify that there is sufficient slack in the cables on both ends
of the CMA.
