Table 82 on page 236 provides the rack requirements and specifications for the switch.
Guidelines
Use a two-post rack or a four-post rack. You can mount the switch on any two-post or
four-post rack that provides bracket holes or hole patterns spaced at 1 U (1.75 in. or
4.45 cm) increments and that meets the size and strength requirements to support the
weight.
A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment
(document number EIA-310–D) published by the Electronics Industry Association
http://www.eia.org
(
The holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm), so that the
switch can be mounted in any rack that provides holes spaced at that distance.
