Tip - Label your cables so they are easy to identify when you need to reconnect them.

1. Unplug power and data cables from the server.

2. Lift the small tab on the CMA-to-chassis bracket to release the right pinhead. See FIGURE G-1.

c. Pull the CMA toward you until the CMA left and right pinheads lock into the keyholes with an audible snap.

2. Insert the other end of the CMA into the slide rail extension and hand-tighten the knurled fastener found on the CMA.

3. Install cables to your server, as required, and route the cables through the CMA cable hangers.
