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 (
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
•
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 (
•
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.
