J4300 and J6300 Chassis

The J4300 and J6300 Services Router chassis is a rigid sheet metal structure that houses all the other router components (see Figure 7 through Figure 12). The chassis can be installed in many types of racks or cabinets. For information about acceptable rack types, see Rack Requirements.

In addition to the features described in subsequent sections, the chassis includes the following features:

• One pair of metal brackets attached to the side of the chassis. You can use the brackets for mounting the chassis in a rack or cabinet.
• One electrostatic discharge (ESD) point, a banana plug receptacle at the front of the chassis.

  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. The protective earthing terminal on the rear of the chassis is provided to connect the router to ground (see Figure 2). Additional grounding is provided to an AC-powered router when you plug its power supply into a grounded AC power receptacle. For additional safety information, see Safety and Regulatory Compliance Information.

• One protective earthing terminal, a PEM nut at the rear of the chassis.

Table 13 summarizes the physical specifications for the router chassis.
