Guidelines
The minimum cabinet size for accommodating a EX4600 switch is 36 in. (91.4 cm)
deep. Large cabinets improve airflow and reduce the chance of overheating.
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.
The EX4600 fans exhaust hot air either through the vents on the port panel or
through the fans and power supplies. 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.
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.

When planning the site for installing an EX4600 switch, you must allow sufficient
clearance around the installed chassis (see
Chapter 7: Rack and Cabinet Requirements
