• One grounding wire. Although we recommend at least 4-AWG multistrand copper wire, the wire diameter
and length depend on your chassis location and site environment.
These parts are not available from Cisco (with the exception of the grounding lug), but they are available from
commercial vendors.
Note
Installing the Chassis Ground Cable
This section describes how to install a ground cable to either NEBS bonding and grounding point on the front
or side of the chassis.
Tools and Equipment
• Ground lug and screws (provided in chassis accessory kit)
• Ground cable
• Crimping tool and lug specific die
• 3/8-inch drive socket wrench
• 3/8-inch drive torque wrench rated to include 35 in-lb (3.95 N-m).
To ensure a satisfactory ground connection, we recommend 4-AWG multistrand copper ground cable. This
cable is not available from Cisco; it is available from any commercial cable vendor. The cable should be sized
according to local and national installation requirements.
The DC return of this system should remain isolated from the system frame and chassis (DC-I: Isolated DC
Return).
