Installing the Universal Four-Post Rack Kit (XEN-
R000296)
Use the following instructions to install 1U and 2U devices in EIA racks that are between L-12.7 to 81.28 cm deep (L-5.0 to 32.0 in.),
where L is the chassis depth, using the Universal Four-Post Rack Kit (XEN-R000296).
There are two ways you can mount the device in a four-post rack:
• With the port side ush with the front posts.
• With the nonport side ush with the rear posts in a recessed position. A recessed position allows a more gradual bend in the
ber-optic cables connected to the switch and less interference in the aisle at the front of the rack.
