Cabinet Requirements and Specifications for an EX8208 Switch

You can mount an EX8208 switch on a cabinet that contains 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).

Cabinet requirements consist of:

•Cabinet size and clearance

•Cabinet airflow requirements

Table 40 on page 100 summarizes cabinet requirements and specifications for EX8208 switches.

Cabinet Requirement	Guidelines for the EX8208 Switch
Cabinet size and clearance	• The minimum cabinet size for accommodating an EX8208
	switch is 23.62 in. (60 cm) wide and 30.0 in. (76.2 cm) deep.
	Large cabinets improve airflow and reduce the chance of
	overheating. To accommodate a single EX8208 switch in
	a four-post rack, the cabinet must be at least 14 U high (or
	15 U if you install the power cord tray, which is optional for
	the four-post rack). To accommodate a single EX8208
	switch in a two-post rack, the cabinet must be at least 15
	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
	stack three EX8208 switches in a cabinet with a four-post
	rack that has at least 42 U of usable vertical space. (45 U
	are required if you install the optional power cord tray.) You
	can stack three EX8208 switches in a cabinet with a
	two-post rack that has at least 45 U of usable vertical space
	(for two-post rack installations, installing the power cord
	tray is mandatory). 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.
