The router chassis is a rigid sheet metal structure that houses the other
hardware components. The chassis is 17.5 in. (44.5 cm) wide and 29 in.
(73.6 cm) deep. The chassis height of 35 in. (89 cm) enables stacked
installation of two M160 routers in a single floor-to-ceiling rack. For more
information, see Rack Requirements on page 59.
The two front support posts and center-mounting brackets (one on each
side) extend the chassis width to 19 in. (48.3 cm) and enable installation
into either a front-mount or a center-mount rack.
Figure 1, Figure 2, and Figure 3 show three views of the router chassis.
