Static rails
The static rails, shown in the figure below, support a wider variety of racks than the sliding rails, but do not support
serviceability in the rack. The static rails are not compatible with the CMA and SRB.
B20 Ready Rails static rails for 4-post and 2-post racks
● Supports Stab-in installation of the chassis to the rails
● Supports tool-less installation in 19-inch EIA-310-E compliant square or unthreaded round hole 4-post racks including all
generations of Dell racks
● Supports tooled installation in 19-inch EIA-310-E compliant threaded hole 4-post and 2-post racks
● Supports tooled installation in Dell EMC Titan or Titan-D rack
NOTE:
● Screws are not included with the static rail kit since racks are offered with various thread types. The screws are
provided for mounting static rails in racks with threaded mounting flanges.
● Screw head diameter should be 10mm or less.

Cable Management Arm
The optional Cable Management Arm (CMA) for the system 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 CMA include:
● Large U-shaped baskets to support dense cable loads.
● Open vent pattern for optimal airflow.
● Support for mounting on either side by swinging the spring-loaded brackets from one side to the other.
● Utilizes 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 through simple and intuitive snap-in designs.
The CMA can be mounted to either side of the sliding rails without the use of tools or the need for conversion. For systems
with one power supply unit (PSU), it is recommended to mount on the side opposite to that of the power supply to allow easier
access to it and the rear drives (if applicable) for service or replacement.
