and Figure 4 on page 7). The chassis measures 8.71 in. (22.1 cm) high,
17.45 in. (44.3 cm) wide, and 24.5 in. (62.2 cm) deep (from the front-mounting
brackets to the rear of the chassis). The chassis installs in standard 800-mm deep
(or larger) enclosed cabinets, 19-in. equipment racks, or telco open-frame racks. See
Table 25 on page 161.
