Table 24 on page 51 provides the cabinet requirements and specifications for an ACX5000
router.
Guidelines
The minimum cabinet size for accommodating a ACX5000 router is 36 in. (91.4 cm)
deep. Large cabinets improve airflow and reduce the chance of overheating.
When you mount the router 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 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.
The ACX5000 router fans exhaust hot air either through the vents on the port
panel or through the fans and power supplies. Install the router 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 router and cabinet.

When planning the site for installing an ACX5000 router, you must allow sufficient
clearance around the installed chassis (see
