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. See Figure 4.

Using the hook and loop straps, bundle the cables and secure them to either the left rail or right rail as described in the Rack Installation Instructions. See Figure 12 for an example of data cables that are secured to the left rail and power cables that are secured to the right rail (as viewed from the rear of the system).
