Chassis

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.

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.

The chassis includes the following electrical safety components:

• Two electrostatic discharge (ESD) points (banana plug receptacles), one front and one rear, as shown in Figure 1 and Figure 2
• Two internally threaded grounding points, as shown in Figure 2

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. For further safety information, see Safety and Regulatory Compliance Information.
