connecting its grounding ports to the rack. Otherwise, you must connect the chassis grounding ports directly
to the data center ground.
Required Tools and Equipment
To connect the system ground, you need the following tools and materials:
• Grounding lug—A two-holed standard barrel lug that supports up to 6 AWG wire. This lug is supplied
• Grounding screws—Two M4 x 8 mm (metric) pan-head screws. These screws are shipped with the Cisco
• Grounding wire—Not supplied with the Cisco Nexus 7010 system accessory kit. This wire should be
• 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 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
Grounding Wire in the Grounding Lug, on page

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.

sized to meet local and national installation requirements. Depending on the power supply and system,
a 12 AWG to 6 AWG copper conductor is required for U.S. installations. We recommend that you use
commercially available 6 AWG wire. The length of the grounding wire depends on the proximity of the
switch to proper grounding facilities.
