Table 24: Cabinet Requirements and Specifications for the Switch

Cabinet
Requirement Guidelines
Cabinet size You can mount the switch in 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 (
The minimum cabinet size must be able to accommodate the maximum external dimensions of the
switch.
Cabinet clearance The outer edges of the mounting brackets extend the width of the chassis to 19 in. (48.2 cm).
The minimum total clearance inside the cabinet is 30 in. (76.2 cm) between the inside of the front
door and the inside of the rear door.
Cabinet airflow When you mount the switch in a cabinet, ensure that ventilation through the cabinet is sufficient to
requirements prevent overheating.
Ensure adequate cool air supply to dissipate the thermal output of the switch or switches.
Ensure that the hot air exhaust of the chassis exits the cabinet without recirculating into the switch.
An open cabinet (without a top or doors) that employs hot air exhaust extraction from the top
ensures the best airflow through the chassis. If the cabinet contains a top or doors, perforations in
these elements assist with removing the hot air exhaust.
Install the switch in the cabinet in a way that maximizes the open space on the side of the chassis
that has the hot air exhaust.
Route and dress all cables to minimize the blockage of airflow to and from the chassis.
Ensure that the spacing of rails and adjacent cabinets is such that there is proper clearance around
the switch and cabinet.
A cabinet larger than the minimum required provides better airflow and reduces the chance of
overheating.

You can install the switch on a desktop or wall. When choosing a location, allow at least
6 in. (15.2 cm) of clearance between the front and back of the chassis and adjacent
equipment or walls.
Ensure that the wall onto which the switch is installed is stable and securely supported.
If you are mounting the switch in sheetrock (wall board with a gypsum plaster core) or
in wall board not backed by wall studs, use hollow wall anchors capable of supporting
