Table 29: Cabinet Requirements for the QFX3500 Device (continued)
Guidelines
Cabinet
Requirement
When you mount the device in a cabinet, ensure that ventilation through the cabinet is
sufficient to prevent overheating.
•
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.
