Rack Requirements for ACX2000 and ACX2100 Routers

You can mount the router on two-post racks or four-post racks.
Rack requirements consist of:
Rack type
Mounting bracket hole spacing
Guidelines
When you mount the router in a cabinet, ensure that
ventilation through the cabinet is sufficient to prevent
overheating.
Ensure an adequate cool air supply to dissipate the
thermal output of the router or routers.
Ensure that the cabinet allows the chassis hot exhaust
air to exit the cabinet without recirculating into the
router. 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 router in the cabinet in a way that maximizes
the open space on the side of the chassis that has the
hot air exhaust. This space 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 router and
cabinet.
A cabinet larger than the minimum required provides
better airflow and reduces the chance of overheating.
