Installing Chassis Ground Connection

All Cisco 3600 series router chassis require a reliable earth ground connection. You must connect the chassis to a reliable earth ground; the ground wire must be installed in accordance with local electrical safety standards.

•For NEBS-compliant grounding, use size AWG 6 (13 mm2) wire and the ground lug provided in the accessory kit.

•For NEC-compliant grounding, use size AWG 14 (2 mm2) or larger wire and an appropriate user-supplied ring terminal.

•For EN/IEC 60950-compliant grounding, use size AWG 18 (1 mm2) or larger wire and an appropriate user-supplied ring terminal.

For chassis grounding instruction, see one of the following sections:

•Cisco 3620 and Cisco 3640 Chassis Ground Connection, page 3-19

•Cisco 3631 Chassis Ground Connection, page 3-24

•Cisco 3660 Chassis Ground Connection, page 3-25

Cisco 3620 and Cisco 3640 Chassis Ground Connection

To connect a Cisco 3620 or Cisco 3640 chassis to ground, perform this procedure:

Step 1 Attach the ground-lug bracket to the power supply as shown in Figure 3-31or Figure 3-32. Use a number 2 Phillips screwdriver and the screw or screws that are already in the router chassis.

For Cisco 3620 routers, use the power-supply retaining screw at the bottom of the power supply.

For Cisco 3640 routers, use the two power-supply retaining screws: one at the lower left and one at the upper right.

DC power supply is shown. The bracket attachment for the AC power supply and the Cisco Redundant Power System (RPS) is similar.
