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 without the CMA represents the minimum depth of the rails
with the outer CMA brackets removed (if applicable) as measured from the front mounting flanges
of the rack.

USB peripherals are supported through the front and back USB ports on the R520. These ports are
