between 1 and 10 megohm (Mohm).
Establishing the System Ground
This section describes how to connect a system ground to the Cisco UCS 6100 Series Fabric
Interconnect.
This system ground is referred to as the network equipment building system (NEBS) ground.
Note
You must use the NEBS ground on AC-powered systems if you are installing this equipment in a U.S.
or European Central Office.
The NEBS 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 NEBS requirements for supplemental bonding and grounding connections. You must
observe the following system grounding guidelines for your chassis:

You must install the NEBS 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 NEBS ground connection and the power supply ground connection to an
earth ground. The NEBS 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 UCS 6100 Series Fabric Interconnect
is equipped with AC-input power supplies.
Grounding lug—A two-hole standard barrel lug. Supports up to 6 AWG wire. Supplied as part of
accessory kit.
Grounding screws—Two M4 x 8mm (metric) pan-head screws. 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 the proximity
of the chassis to proper grounding facilities.
No. 1 Phillips head screwdriver.
Crimping tool to crimp the grounding wire to the grounding lug.
Wire-stripping tool to remove the insulation from the grounding wire.
