Connecting the System Ground
After you have moved the chassis into the rack or cabinet, you are ready to connect the system to the data
center 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 data center 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 15: Inserting the
Grounding Wire in the Grounding Lug, on page 33.

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 the system grounding pad on the chassis, secure the grounding wire lug to the grounding
pad with two M4 screws, and tighten the screws to 11.5 to 15 in-lb (1.3 to 1.7 N·m). Callout 1 in Figure 16: Grounding
Pad and ESD Port Locations on the Cisco Nexus 7004 Chassis, on page 34 shows the location of the grounding pad on
the front side of the chassis.
Be sure that the grounding lug and wire do not block the ESD port by positioning the lug and wire connection
above the grounding port.
