1.5 Left-Side Mounting Instructions

Install the CMA on the rear left 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. For left-side mounting, if the cable bundle includes a

keyboard, video, and mouse (KVM) dongle, place the dongle inside the CMA basket. See Figure 4.

Figure 4: Routing the Cables Through the CMA

3. 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.

4. 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.

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

of the CMA.

See Figure 5 for an example of a completed left-side mounted CMA installation.

Best Practices Guide for

NOTE: Do not store excess cable

slack inside the CMA. The cable may

protrude through the CMA, thus

causing binding and potentially

damaging the cable.

Cables entering the CMA should have

a small amount of slack to avoid cable

strain when the CMA is extended.
