Chapter2 Installing the Cisco Nexus 6000 Series Switches Grounding the Switch
Establishing the System Ground
This section describes how to connect a system ground to the Cisco Nexus 6000 Series switch.
You must use the system ground on AC-powered systems if you are installing this equipment in a U.S.
or European Central Office.
The system ground provides additional grounding for EMI shielding requirements and grounding for the
low-voltage supplies (DC-DC converters) on the modules and is intended to satisfy the Telcordia
Technologies requirements for supplemental bonding and grounding connections. You must observe the
following system grounding guidelines for your chassis:
•You must install the system ground connection with any other rack or system power ground
connections that you make. The system ground connection is required if this equipment is installed
in a U.S. or European Central Office.
•You must connect both the system ground connection and the power supply ground connection to
an earth ground. The system ground connection is required if this equipment is installed in a U.S.
or European Central Office.
•You do not need to power down the chassis because the Cisco Nexus 6000 Series switches are
equipped with AC-input power supplies.
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. Supplied as
part of 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 as part of 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 t he 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 6000 Series Chassis
The chassis has a grounding pad with two threaded M4 holes for attaching a grounding lug. The location
of the system ground on the Cisco Nexus 6004 switch is similar to that on the Cisco Nexus 5500 Platform
switches.
Note For the procedure on how to ground the Cisco Nexus 6000 Series switch chassis, see the “Grounding the
Cisco Nexus 6000 Series Chassis” section on page 2-11.
