Installing On Desktop; Grounding The Chassis - Cisco 2691 Quick Start Manual

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 mm
• For NEC-compliant grounding, use size AWG 14 (2 mm
• For EN/IEC 60950-compliant grounding, use size AWG 18 (1 mm
terminal.
To connect the chassis to a reliable earth ground, perform the following steps:
Strip one end of the ground wire to the length required for the ground lug or terminal.
Step 1
• For the NEBS ground lug—approximately 0.75 in. (20 mm)
• For user-provided ring terminal—as required
Crimp the ground wire to the ground lug or ring terminal, using a crimp tool of the appropriate size.
Step 2
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
Step 3
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).
Connect the other end of the ground wire to a grounding point at your site.
