Why Independent Grounding & Bonding is essential to your facility’s data center:


  • An active, functioning ground system provides protection to personnel and equipment. Proper grounding & bonding are essential for efficient network performance.
  • Independent grounding and bonding is just as essential as your building ground.
  • Blade Servers run at high speeds and are are highly sensitive to electrical interference (EMI/Noise)- they need clean power.


What are the effects of improper grounding?


  • Lower reliability
  • Safety Risks
  • Potential Fire Hazards
  • An improperly designed grounding system may be a primary source of interference and emission.
  • Poorly designed or improperly applied grounding, bonding, and shielding techniques often adversely affect the performance of electronic equipment- from the circuit board to the network system.


From your data center, to the manufacturing floor, to facilities operations, there are critical systems and equipment that require proper grounding and bonding. Protecting those systems, equipment, and personnel helps to ensure equipment reliability and thus availability of services, while resulting in lower operational expense.
