Rack Requirements for EX3200 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 1 provides the rack requirements and specifications for the switch.

Table 1: Rack Requirements and Specifications for the Switch

Rack Requirement	Guidelines
Rack type	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 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 rack must meet the strength requirements to support the weight of the chassis.
Mounting bracket hole spacing	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.
Rack size and strength	Ensure that the rack complies with standard defined for 19-in. rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310–D) published by the Electronics Industry Association (http://www.eia.org). Ensure that the rack rails are spaced widely enough to accommodate the switch chassis' external dimensions . The outer edges of the front-mounting brackets extend the width of the chassis to 19 in. (48.2 cm). The rack must be strong enough to support the weight of the switch. Ensure that the spacing of rails and adjacent racks allows for the proper clearance around the switch and rack.
Rack connection to building structure	Secure the rack to the building structure. If earthquakes are a possibility in your geographical area, secure the rack to the floor. Secure the rack to the ceiling brackets as well as wall or floor brackets for maximum stability.

One pair of mounting brackets for mounting the switch on two posts of a rack is supplied with each switch. For mounting the switch on four posts of a rack or cabinet, you can order a four-post rack-mount kit separately.
