Rack Requirements for EX2200 Switches

You can mount the switch on two-post racks or four-post racks.

Rack requirements consist of:

•

Rack type

•

Mounting bracket hole spacing

•

Rack size and strength

•

Rack connection to the building structure

Table 18 on page 39 provides the rack requirements and specifications for the switch.

Table 18: Rack Requirements and Specifications for the Switch

GuidelinesRack Requirement

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./4.45 cm) increments and

that meets the size and strength requirements to support the weight.

A U is the standard rackunit defined in Cabinets, Racks, Panels, and Associated Equipment (document

number EIA-310–D) published by the Electronics Industry Association (http://www.eia.org).

The rack must meet the strength requirements to support the weight of the chassis.

Rack type

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.
