1.2. Routing the power cables through the strain reliefs
After you have installed the tray and cables, route the power cables through the strain reliefs located
on the power supply handles as shown in Figure 2.

1.3. Installing the CMA
NOTE: If you are installing fiber-optic cables in the CMA, a cable bend radius of at least 1 inch must be
maintained throughout the length of the cable. It is recommended that fiber-optic cables be routed on
the exterior of the cable bundle to increase the bend radius of the fiber-optic cables through the CMA.
Additionally, a large amount of slack at the entrance and exit of the CMA is recommended.
1. Install the CMA on the rear right or rear left side of the rails by attaching both CMA housings to the
attachment brackets on the rails as described in the CMA Installation Instructions.
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 system interface pod (KVM SIP), it can
be placed inside the CMA basket. See Figure 3.

NOTE: Do not store excess cable
slack inside the CMA. The cables
may protrude through the CMA, thus
causing binding and potentially
Cables entering the CMA should have a
small amount of slack to avoid cable
strain when the CMA is extended.
KVM SIP can be placed
inside the CMA basket.
