Lightning, fault currents, circuit switching (motors turning on and o), and electrostaƟc discharge are common causes of these surges and transient voltages. An eecƟve grounding system minimizes the detrimental eects of these electrical surges, which include degraded network performance and reliability and increased safety risk. ELECTRICAL DISTURBANCES: Data center equipment is sensiƟve to electrical disturbances. While minimum grounding requirements are designed for personnel safety and re prevenƟon purposes, data center downƟme and damage to equipment as a result of inadequate grounding can cost an organizaƟon millions of dollars. According to insurance industry data, improper grounding of communicaƟon systems leads to $500 million per year of damage to property and/or equipment due to lightning. ELECTRICAL NOISE: In a data center, electrical noise is introduced on data cables when surges are not properly dissipated by the grounding system, resulƟng in lost data and network ineciencies. Rack ground bonding improves data transmission eciencies by reducing the “noise” polluƟng the computer network. BEST PRACTICES: According to TIA942 and the IEEE any metallic component that is part of the system including racks, cabinets, cable trays, servers and other equipment must be bonded to the grounding system. TIA942 requires each rack to bond directly to the grounding grid or common bonding network, direcƟng current away from sensiƟve electronics. Proper grounding is the most important factor in reliable network equipment performance. According to the IEEE the typical AC third prong ground is almost never sucient to prevent damage to network equipment. Establish electrical conƟnuity throughout racks and cabinets for safety and electrostaƟc discharge (ESD) protecƟon, and proper grounding and bonding of network equipment. The grounding should direct damaging currents away from equipment. You want a grounding system that directs damaging currents away from equipment. Data center grounding systems serve several funcƟons; prevenƟng electrical noise, providing surge protecƟon and eliminaƟng electrical disturbances. Rack and Cabinet Ground Bonding

GROUNDING SYSTEMS:  The purpose of a grounding system is to create a low impedance path to earth ground for electrical surges and transient voltages.  Lightning, fault currents, circuit switching (motors turning on and off), and electrosta c discharge are common causes of these surges and transient voltages.  An effec ve grounding system minimizes the detrimental effects of these electrical surges, which include degraded network performance and reliability and increased safety risk.   

 ELECTRICAL DISTURBANCES:  Data center equipment is sensi ve to electrical disturbances.  While minimum grounding requirements are designed for personnel safety and fire preven on purposes, data center down me and damage to equipment as a result of inadequate grounding can cost an organiza on millions of dollars.    According to insurance industry data, improper grounding of communica on systems leads to $500 million per year of damage to property and/or equipment due to lightning.    

ELECTRICAL NOISE:  In a data center, electrical noise is introduced on data cables when surges are not properly dissipated by the grounding system, resul ng in lost data and network inefficiencies.      Rack ground bonding improves data transmission efficiencies by reducing the “noise” pollu ng the computer network.    

BEST PRACTICES:  According to TIA‐942 and the IEEE any metallic component that is part of the system including racks, cabinets, cable trays, servers and other equipment must be bonded to the grounding system.    

TIA‐942 requires each rack to bond directly to the grounding grid or common bonding network, direc ng current away from sensi ve electronics.  

Proper grounding is the most important factor in reliable network equipment performance.  According to the IEEE the typical AC third prong ground is almost never sufficient to prevent damage to network equipment.    Establish electrical con nuity throughout racks and cabinets for safety and electrosta c discharge (ESD) protec on, and proper grounding and bonding of network equipment.  The grounding should direct damaging currents away from equipment.
