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).

IMPORTANT: You must attach three Velcro® straps to each CMA to assure stability during shipment
or transportation
1. Remove three Velcro® straps from the rack accessory package and remove the plastic mount, as
shown:
2. Insert straps in the left rear side panel and orientate the harnesses as shown in the image below,
left.

3. Adjust and tighten the straps until the CMA is horizontal. See image below, right.
NOTE: Tighten the straps enough to prevent interference with movement or pinched cables, and
to assure free movement of the CMA assembly.
