Chassis Grounding
After you set up the router, connect the chassis to a reliable earth ground; the ground wire must be installed
in accordance with local electrical safety standards. For safety information on grounding the chassis, refer to
the chassis ground connection procedures.
1. For grounding the chassis, use size 14 AWG copper wire and the ground lug. These are not a part of the
accessory kit.
2. Use the UNC 6-32 screw provided with the chassis, which have a length of about 0.25 inches.
To install the ground connection for your router, perform these steps:
1. Strip one end of the ground wire to the length required for the ground lug or terminal.
For user-provided ring terminal—as required
2. Crimp the ground wire to the ground lug or ring terminal, using a crimp tool of the appropriate size.
3. Attach the ground lug or ring terminal to the chassis as shown in Figure 23: Chassis Ground
Connection-Cisco 900, on page 28. The screw for the ground lug is provided. Tighten the screw; the
recommended torque is 8 to 10 inch-lbf (0.9 to 1.1 N-m).
