Install the Controller CMA

The cable management arm (CMA) clips into the ends of the left and right Controller slide rail assemblies. No screws are necessary for mounting the CMA. The right sides of the two CMA arms have hinged extensions. On the manufacturer's instruction sheet, the smaller extension is called the CMA Connector for Inner Member. It attaches to the right mounting bracket. The larger extension is called the CMA Connector for Outer Member, and attaches to the right sliding rail.

1. At the back of the rack, plug the CMA rail extension into the end of the left slide rail assembly.
