Guidelines
When you mount the switch 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 switch (or switches).
•
Ensure that the cabinet allows the chassis hot exhaust air to exit the
cabinet without recirculating into the switch. 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.
•
Install the switch in the cabinet in a way that maximizes the open
space on the FRU side of the chassis. This maximizes the clearance
for critical airflow. The QFX10002 fans exhaust hot air through the
fans and power supplies.
•
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 switch and cabinet.
