The adjustment range of the rails is a function of the type of rack in which they are being mounted.
The minimum and maximum 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 rail with the outer CMA brackets removed (if applicable) as measured from the front mounting
flanges of the rack.
USB peripherals
USB peripherals are supported through the front, back, and internal USB ports. They are USB 2.0
compliant.
