Required Tools and Equipment

To connect the system ground, you need the following tools and materials:

Grounding lug—A two-hole standard barrel lug. This lug supports up to 6 AWG wire. This lug is supplied in the accessory kit.

Grounding screws—Two M4 x 8mm (metric) pan-head screws. These screws are supplied as part of the accessory kit.

Grounding wire—Not supplied in the accessory kit. The grounding wire should be sized according to 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. Commercially available 6 AWG wire is recommended. 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.

Grounding the Cisco Nexus 3000 Series Chassis

The chassis has a grounding pad with two threaded M4 holes for attaching a grounding lug. The system ground is located on the left side of the chassis (left of the front) on the Cisco Nexus 3000 Series switches.

Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046

Caution We recommend grounding the chassis, even if the rack is already grounded.

Caution All power supplies must be grounded. The receptacles of the AC power cables used to provide power to the chassis must be the grounding type, and the grounding conductors should connect to protective earth ground at the service equipment.

Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last.

Statement 1046

To attach the grounding lug and cable to the chassis, follow these steps:

Step 1 Use a wire-stripping tool to remove approximately 0.75 inches (19 mm) of the covering from the end of the grounding cable.

Step 2 Insert the stripped end of the grounding cable into the open end of the grounding lug (see Callout 1 in Figure 2-6).
