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.

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.
