Chapter 2 Installing a Cisco Nexus 7010 Chassis
Grounding the Cisco Nexus 7010 Chassis
Prerequisites for Grounding the Chassis
Before you can ground the chassis, you must have a connection to the earth ground for the data center
building. If you installed the Cisco Nexus 7010 chassis into a bonded rack (see the rack manufacturer’s
instructions for more information) that now has a connection to the data center earth ground, you can
ground the chassis by 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 with the Cisco Nexus 7010 system accessory kit.
• Grounding screws—Two M4 x 8 mm (metric) pan-head screws. These screws are shipped with the
Cisco Nexus 7010 accessory kit.
• Grounding wire—Not supplied with the Cisco Nexus 7010 system accessory kit. This wire should
be 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.
• No. 1 Phillips screwdriver.
• 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
Figure 2-5.
