How to ground the server rack?

Answer 1

Data Centres can have up to 30 times the electrical density of a standard office building and with high safety and power demands. For safety reasons, low-voltage systems—such as electrical services, telecommunications equipment—are required to be bonded to ground per national and local electrical codes and industry standards.

A server rack grounding system is essential to ensure data centre’s uptime. But before going into the detail of how grounding works well for your rack, let’s first see the key difference between Grounding and Bonding.

Bonding is generally done as a protective measure from electrical shocks by joining the last of metallic pieces to form a conducting path. Grounding, however, is any intentional or unintentional connection between an electrical circuit and the earth. Grounding ensures all metal parts of an electrical circuit are connected to the earth. It doesn’t impact the regular working of the electrical system. Bonding alone does not manage to protect anything, but if one of the cabinet boxes is grounded, electrical energy stock up will not be possible and the server rack will be safe from any potential threat.

Why are bonding and grounding important……...

In a successfully installed grounding and bonding system, leakage currents have to be deviated from the data centre equipment. It will bond metallic components to the system in a way that conductive materials at the same electrical potential to decrease the current flow. If the current were to reach the equipment, it could cause great damage. To avoid any adverse effect to the performance of electronic equipment grounding & bonding techniques must be properly applied since IT equipment is highly prone to get damaged due to leakage current.
