Screws are not included in the static rail kit because threaded racks are offered with a variety of thread
designations. Users must provide their own screws when mounting the static rails in threaded or 2-post racks.
Other key factors governing proper rail selection include the spacing between the front and rear mounting
flanges of the rack, the type and location of any equipment mounted in the back of the rack such as power
distribution units (PDUs), and the overall depth of the rack. See Table 15.
Due to their reduced complexity and lack of need for CMA support, the static rails offer a greater adjustability
range and an overall smaller footprint than the sliding rails.

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.
Cable Management Arm (CMA)
The optional cable management arm (CMA) for the R710 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 R710 CMA include:
Large U-shaped baskets support dense cable loads.
An open vent pattern allows for 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 provided to both support and retain the CMA in its fully closed position.
The CMA and the tray mount without the use of tools using simple and intuitive snap-in designs.
