Table 28: Cabinet Requirements and Specifications for the Switch

Cabinet Requirement	Guidelines
Cabinet size and clearance	■ The minimum cabinet size for accommodating a switch
	is 23.62 in. (60 cm) wide and 30 in. (76.2 cm) deep.
	Large cabinets improve airflow and reduce the chance
	of overheating. To accommodate a single switch in a
	two-post rack or four-post rack, the cabinet must be at
	least 1 U high.
	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).
	■ With adequate cooling air and airflow clearance, you
	can mount 42 switches in a cabinet with a two-post or
	four-post rack that has at least 42 U of usable vertical
	space. In all cases, the rack must meet the strength
	requirements to support the weight.
	■ The minimum total clearance inside the cabinet is
	29.2 in. (74.17 cm) between the inside of the front door
	and the inside of the rear door.
