MX480 Chassis Description
The router chassis is a rigid sheet metal structure that houses all the other router
components (see
Figure 1 on page 32 , Figure 2 on page 33 , and Figure 3 on page 33 ). The
chassis measures 14.0 in. (35.6 cm) high, 17.45 in. (44.3 cm) wide, and 24.5 in. (62.2 cm)
deep (from the front to the rear of the chassis). The chassis installs in standard 800-mm
(or larger) enclosed cabinets, 19-in. equipment racks, or telco open-frame racks. Up to
five routers can be installed in one standard 48-U rack if the rack can handle their
combined weight, which can be greater than 818 lb (371.0 kg).
