2.3 Routing the Cables Through the CMA
NOTE: The CMA can be installed on either the right or left rear side of the rails. Mounting the CMA on the side
opposite the power supplies (left side mount) is recommended; otherwise, the CMA must be disconnected in order
to remove the outer power supply. Refer to “Replacing a Power Supply on a PowerEdge R710 with CMA” later in
this white paper for details on power supply replacement.
NOTE: For guidelines on how to route cables within the rack, refer to the Dell White Paper “Best Practices Guide
for Rack Enclosure”.
Left Side Mounting Instructions
1. Install the CMA on the left rear side of the rails by attaching both CMA housings to the attachment brackets on
the rails. See Figure 3.
2. Route the cables through the CMA while keeping any twisting of the cables to a minimum. If the cable bundle
includes a KVM dongle, place the dongle inside the CMA basket. Use the hook and loop straps on the CMA to
secure the cables.
