Grounding new racks installed in a data center is essential for safety and operational integrity. Proper grounding helps to prevent electrical hazards such as shock, ensures the safe dissipation of stray electrical currents, and can protect sensitive equipment from damage caused by electrical surges or faults.

When racks are grounded, any fault current has a safe pathway to the ground, minimizing the risk of equipment failure and improving overall system reliability. This practice also helps to reduce electromagnetic interference, which can adversely affect the performance of electronic components housed in the racks.

In addition, regulatory standards and best practices in data centers often mandate grounding as part of electrical safety codes. Therefore, grounding is not merely a precaution; it is a necessary step to comply with safety regulations and ensure the longevity of the equipment.

While the grounding of metal racks is crucial, it is equally important for non-metal racks, especially if they contain electrical equipment or wiring. Thus, the answer supports the rationale that grounding is a fundamental requirement for all racks in a data center environment.
