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 24 in. (61 cm) deep. The chassis height of 5.25 in. (13.3 cm) enables stacked installation of 14 M5 and M10 routers in a single floor-to-ceiling rack. For more information, see Rack Requirements.
The two mounting ears (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 front and rear views of the router chassis.

The chassis includes two electrostatic discharge (ESD) points (banana plug receptacles) for electrical safety, one front and one rear, as shown in Figure 1, Figure 2, and Figure 3.

Before removing or installing components of a functioning router, attach an ESD strap to an ESD point and place the other end of the strap around your bare wrist. Failure to use an ESD strap could result in damage to the router. The router must be connected to earth ground during normal operation.
