Installing the cable management brackets

The Cable Management System (CMS), also called a Cable Management Arm (CMA) keeps the cables

from becoming entangled when the system is fully extended from the equipment rack. The cables are

routed along the length of the bracket and held in place with Velcro® cable ties. The CMA is a

component added to the VMA-series chassis rack-mount option. The CMA is installed at the rear of

the chassis.

NOTE: The CMA is installed prior to shipping.

This document describes how to install the cable management brackets needed to clip on the Cable

Management Arm (CMA).

shown:

2. Insert straps in the left rear side panel and orientate the harnesses as shown in the image below,

left.
