Rack-Mounting and Cabinet-Mounting Warnings on page 210

•

Cabinet Requirements

You can mount the device in a cabinet that contains a 19-in. rack.

Cabinet requirements consist of:

•

Cabinet size

•

Clearance requirements

•

Cabinet airflow requirements

Table 36 on page 60

provides the cabinet requirements and specifications.

Table 36: Cabinet Requirements and Specifications

Guidelines

Cabinet
Requirement

•

You can mount the device 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 (

http://www.ecianow.org/standards-practices/standards/

).

•

The minimum cabinet size must be able to accommodate the maximum external dimensions of the
device.

Cabinet size

•

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 clearance

When you mount the device in a cabinet, ensure that ventilation through the cabinet is sufficient to
prevent overheating.

•

Ensure adequate cool air supply to dissipate the thermal output of the device or devices.

•

Ensure that the hot air exhaust of the chassis exits the cabinet without recirculating into the device.
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 device 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 device and cabinet.

•

A cabinet larger than the minimum required provides better airflow and reduces the chance of
overheating.
