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.

The rail depth changes based on which version of the R620 is being installed. Although the 10-drive
bay system is 50 mm deeper than the 8-drive bay system, both are able to share the same rails
through a new self-adjusting feature included on the rails.

USB peripherals are supported through the front and back USB ports on the R620. These ports are
USB 2.0 compliant.

Table 36 provides the dimensions of the PCIe cards supported by the R620.
