MX204 Router Cabinet Requirements and Specifications

Table 20 on page 58 summarizes cabinet requirements and specifications for the MX204 router.

Guidelines for the MX204 Router
The minimum-sized cabinet that can accommodate the router is 19-in. (482-mm)
wide, and 23.62-in. (600-mm) deep. A cabinet larger than the minimum
requirement provides better airflow and reduces the chance of overheating. If
you provide adequate cooling air and airflow clearance, you can stack several
routers in a cabinet that has sufficient usable vertical space. Each router requires
1 U.
A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated
Equipment (document number EIA-310-D) published by the Electronic
Components Industry Association (ECIA) (http://www.ecianow.org).
With adequate cooling air and airflow clearance, you can stack multiple MX204
routers in a cabinet with a four-post rack. In all cases, the rack must meet the
strength requirements to support the weight.
The minimum total clearance inside the cabinet is 30.7 in. (780 mm) between
the inside of the front door and the inside of the rear door.
