For a four-post rack mount, you combine the bundled pair of rack ears with a pair of chassis rack rails providing up to 600mm depth in a four-post rack. The chassis rack rail assembly is bundled with the appliance at time of purchase. This kit also is provided as a field-replaceable unit; for information see Replaceable Unit and SFP Part Numbers.
Align the mounting holes on the rack ears with the front-most mounting holes on each side of the chassis.
Attach the rack ears to each side of the chassis with two (2) 8-32 screws, as shown in the following figure:
