You can mount the router on two-post racks or four-post racks.
Rack requirements consist of:
Rack type
Mounting bracket hole spacing
Rack size and strength
Rack connection to the building structure
Table 17 on page 37 provides the rack requirements and specifications for the router.
Guidelines
When you mount the router in a cabinet, ensure that ventilation
through the cabinet is sufficient to prevent overheating.
Ensure that 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.
