Cable management arm (CMA)

The optional cable management arm (CMA) for the sliding rails organizes and secures the cords and
cables exiting the back of the server and unfolds to allow the server to extend out of the rack for
service without having to detach the cables. Key features of the CMA shown in Figure 16 include:
•
Large U- shaped baskets to support dense cable loads
•
Open vent pattern for optimal airflow
•
Fully reversible (can be mounted on either side) with no conversion required
•
Uses hook- and- loop straps rather than plastic tie wraps to eliminate the risk of cable damage
during cycling
•
Includes a low profile fixed tray to both support and retain the CMA in its fully closed position
•
Both the CMA and the tray mount without the use of tools with intuitive snap- in designs
