Rack Requirements for EX3300 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 26 provides the 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. 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 ) .

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 the size and strength standards of a 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 external dimensions of the switch chassis. The outer edges of the front mount 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 provides for 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.
