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 18 in. (45.7 cm) deep. The chassis
height of 8.7 in. (22.1 cm) enables stacked installation of eight M10i routers in a single

The two mounting brackets (one on each side) extend the chassis width to 19 in.
