Table 88: Cabinet Requirements for the QFX3500 Device

Cabinet Requirement Guidelines
Cabinet size and The minimum cabinet size for accommodating a QFX3500 device is 36 in. (91.4 cm) deep. Large
clearance cabinets improve airflow and reduce the chance of overheating.
Cabinet airflow When you mount the device in a cabinet, ensure that ventilation through the cabinet is sufficient to
requirements prevent overheating.

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.

Ensure that the cool air supply you provide through the cabinet adequately dissipates the thermal
output of the device (or devices).
Ensure that the cabinet allows the chassis hot exhaust air to exit 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.
The device fans exhaust hot air through the rear of the chassis. Install the device in the cabinet in
a way that maximizes the open space on the fan tray side of the chassis. This maximizes the
clearance for critical airflow.
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 allows for the proper clearance around the
device and cabinet.
