Left-side mounted CMA installation (preferred) Figure 5.
1.3.3. 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 KVM SIP, its length may be too short for it to be placed inside the
CMA basket. Route the remainder of the cable that is beyond the SIP module through the CMA. DO
NOT secure the SIP 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 SIP.
4. Once you have routed all of 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 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.
6. 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 6 for an example of a completed right-side mounted CMA installation.
