Cable Management Arm
The static rails for the R250 support a wide variety of racks and mounting configurations, but do not support the ability to
extend the system out of the rack for service. Thus, they do not provide support for a cable management arm (CMA).
Rack View
The PowerEdge R250 rails are a “stab-in” design, meaning that the inner (chassis) rail members must first be attached to the
sides of the system and then inserted into the outer (cabinet) members installed in the rack.
