Chapter 3 Installing the Router
Installing Chassis Ground Connection
Cisco 3631 Chassis Ground Connection
To connect a Cisco 3631 chassis to ground, perform this procedure:
Step 1 Strip one end of the ground wire to the length required for the ground lug or terminal.
–
For the NEBS ground lug—approximately 0.75 in. (20 mm)
–
For user-provided ring terminal—as required
Step 2 Crimp the ground wire to the ground lug or ring terminal, using a crimp tool of the appropriate size.
Step 3 Attach the ground lug or ring terminal to the chassis as shown in Figure 3-39 or Figure 3-40. For the
ground lug, use the two screws with captive locking washers provided. For a ring terminal, use one of
the screws provided. Use a number 2 Phillips screwdriver, and tighten the screws to a torque of 8 to 10
in-lb (0.9 to 1.1 N-m).
Step 4 Connect the other end of the ground wire to a suitable grounding point at your site.

After the router has been installed and properly grounded, you can connect the power wiring; the WAN,
LAN, and voice cables; and the cables for administrative access, as required for your installation. For
cable connection procedures, see the “Power Connections” section on page 3-27, the “Connecting WAN,
LAN, and Voice Cables” section on page 3-37, and the “Connecting to a Console Terminal or Modem”
section on page 3-43.
