The adjustment range of the rails is a function of the type of rack in which they are being mounted. The
min-max values listed above represent the allowable distance between the front and rear mounting flanges
in the rack. Rail depth represents the minimum depth of the rail as measured from the rack front mounting
flanges when the rail rear bracket is positioned all the way forward.
13.3 Cable Management Arm (CMA)
The optional cable management arm (CMA) for the R415 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 without having to detach
the cables. Some key features of the R415 CMA include:
 Large U-shaped baskets support dense cable loads.
 An open-vent pattern allows optimal airflow.
 The CMA mounting is fully-reversible (can be mounted on either side) with no conversion required.
 Hook-and-loop straps are used (rather than plastic tie wraps) to eliminate the risk of cable damage
during cycling.
 A low-profile fixed tray is included to support and retain the CMA in its fully-closed position.
 The CMA and the tray can be mounted without the use of tools using simple and intuitive snap-in
designs.
