Installing on Desktop

Caution If you place the Cisco router on a desktop, do not place anything that weighs more than 10 pounds (4.5 kilograms) on top of the chassis.

Grounding the Chassis

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.

To connect the chassis to a reliable earth ground, perform the following steps:

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 6 or Figure 7. 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 grounding point at your site.
