Establishing System Ground
The system ground is referred to as the network equipment building system (NEBS) ground. 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.
