The services gateway chassis is a rigid sheet metal structure that houses all the other components (see Figure 1, Figure 2, and Figure 3). 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 frontto 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 services gateways 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); see Table 28.
