The minimum size cabinet that can accommodate the router is 600 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 12 U (21 in. or 53.4 cm) high. If you provide adequate cooling air and
airflow clearance, you can stack four routers in a cabinet that has at least 48 U (84 in. or
2.1 m) of usable vertical space.
