Universal Four-Post Rack Kit Installation Procedure
Contents
This document provides instructions to install switches 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 (XBR-
R000296).
Introduction
The rack kit allows the device to be installed so that the port side is either flush with the front posts or
recessed with the nonport side flush with the rear posts. A recessed position allows a more gradual
bend in the fiber-optic cables connected to the switch and less interference in the aisle at the front of the
rack.
NOTE
Although this document describes how to install both single height (1U) and double height (2U)
switches, the illustrations show a 1U switch as a typical installation.
Installation requirements
Allow 15 to 30 minutes to complete this procedure. Provide space in an EIA rack with the following
minimum and maximum distances between the front and back posts.

Note that if chassis depth (L) is less than 40.64 cm (16 in.), the chassis will not fit into a rack with a
maximum depth of 81.28 cm (32 in.) using this rack kit. The maximum rack depth for a chassis less than
40.64 cm (16 in.) is 81.28 cm (32 in.) minus the difference between the chassis depth and 40.64 cm (16
in.). For example, a chassis with a depth (L) of 35.56 cm (14 in.) is 5.08 cm (2 in.) smaller than 40.64
cm (16 in.), so it will install into a rack with a maximum depth of 81.28 cm (32 in.) - 5.08 cm (2 in.) =
76.2 cm (30 in.).
• Verify that the additional weight of the switch does not exceed the rack weight limits.
• Ensure that an electrical branch circuit with the following characteristics is available:
