Grounding the Cisco Nexus 7018 Chassis
•
Number 1 Phillips-head screwdriver with torque capability.
• Crimping tool to crimp the grounding wire to the grounding lug.
•
Wire-stripping tool to remove the insulation from the grounding wire.
Connecting the System Ground
After you have moved the chassis into the rack or cabinet, you are ready to connect the system to the
earth ground. After you ground the chassis, you can ground your ESD wrist strap by connecting it to the
chassis.
To connect the system ground to the earth ground, follow these steps:
Step 1
Use a wire-stripping tool to remove approximately 0.75 inch (19 mm) of the covering from the end of
the grounding wire.
Step 2 Insert the stripped end of the grounding wire into the open end of the grounding lug as shown in
Figure 5-5 .

Step 3
Use the crimping tool to crimp the lug to the grounding wire. Verify that the ground wire is securely
attached to the ground lug by attempting to pull the wire out of the crimped lug.
Step 4
Remove the adhesive label from one of the two system grounding pads, and secure the grounding wire
lug to the grounding pad with two M4 screws.
Figure 5-6 shows the location of the grounding pad on the
front side of the chassis. Ensure that the grounding lug and the grounding wire do not interfere with other
switch hardware or rack equipment.
