Installing the Cable Management Arm on the Sun Fire X4170 M2 Server

The cable management arm (CMA) is an optional assembly that you can use to route the server cables in the rack.

Install Cable Management Arm

Use this procedure to install the optional CMA.

1. Unpack the CMA parts.
2. Take the CMA to the back of the equipment rack and ensure that you have adequate room to work around the back of the server.

   Note - References to “left” or “right” in this procedure assume that you are facing the back of the equipment rack.

3. Remove the tape to separate the parts of the CMA.

   The CMA rail extension might be taped to the CMA arm.

4. Attach the CMA rail extension into the left slide-rail until the extension locks into place with an audible click (Inserting the CMA Rail Extension Into the Back of the Left Slide-Rail).
