Cabinet Requirements and Specifications for a J-EX8208 Switch
You can mount a J-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 31 on page 66 summarizes cabinet requirements and specifications for J-EX8208
switches.

Guidelines for the J-EX8208 Switch Cabinet Requirement
•
The minimum cabinet size for accommodating a J-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 J-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 J-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 J-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 J-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.
