The minimum size cabinet that can accommodate the device is 482 mm wide and 800 mm deep.
A cabinet larger than the minimum requirement provides better airflow
and reduces the chance of overheating. To accommodate a single device,
the cabinet must be at least 13 U
high. If you provide adequate cooling air and airflow clearance, you
can stack five devices in a cabinet
that has at least 48 U (84 in. or 2.13 m) of usable vertical space.
The minimum front and rear clearance requirements depend on
the mounting configuration you choose. The minimum total clearance
inside the cabinet is 30.7 in. between the inside of the front
door and the inside of the rear door.
Cabinet Airflow Requirements
When you mount the device in a cabinet, you must
ensure that ventilation through the cabinet is sufficient to prevent
overheating. Following is a list of requirements to consider when
planning for chassis cooling:
Ensure that the cool air supply you provide through the
cabinet can adequately dissipate the thermal output of the device.
Ensure that the cabinet allows the chassis hot exhaust
air to exit from the cabinet without recirculating into the device.
An open cabinet (without a top or doors) that employs hot air exhaust
extraction from the top allows 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. For an illustration of chassis
airflow, see Figure 20.
Install the device as close as possible to
the front of the cabinet so that the cable management system just
clears the inside of the front door. This maximizes the clearance
in the rear of the cabinet for critical airflow.
Route and dress all cables to minimize the blockage of
airflow to and from the chassis.
