MX480 Router Cabinet Size and Clearance Requirements
The minimum size cabinet that can accommodate the router is 482 mm wide and 800 mm
deep. A cabinet larger than the minimum requirement provides better airflow and reduces
the chance of overheating. To accommodate a single router, the cabinet must be at least
13 U high. If you provide adequate cooling air and airflow clearance, you can stack five
routers in a cabinet that has at least 48 U (84 in. or 2.13 m) of usable vertical space.
The minimum front and rear clearance requirements depend on the mounting
configuration you choose. The minimum total clearance inside the cabinet is 30.7 in.
between the inside of the front door and the inside of the rear door.
