Rack Requirementsfor EX2200 Switches

Youcan mount the switch on two-post racksor four-post racks.

Rackrequirements consist of:

•Racktype

•Mountingbracket hole spacing

•Racksize and strength

•Rackconnection to the building structure

Table18 on page 39 provides the rackrequirements and specifications for the switch.

Table18: Rack Requirements and Specifications forthe Switch

GuidelinesRack Requirement

Usea two-post rack or a four-post rack. Youcan mount the switch on any two-post or four-post

rackthat provides bracket holes or holepatterns spaced at 1 U (1.75 in./4.45cm) increments and

thatmeets the size and strength requirements to support the weight.

AU is the standard rack unit definedin Cabinets, Racks, Panels, and AssociatedEquipment (document

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

Therack must meet the strength requirements to support the weight of the chassis.

Racktype

Theholes in the mounting brackets are spaced at1 U (1.75 in. or 4.45 cm), so that the switch can

bemounted in any rack that provides holes spacedat that distance.
