Grounding for 21st century data centers

The existing standards for the proper grounding of electronic equipment were developed over 20 years ago. At the time, one of the primary concerns was the proper operation of main frame computers installed in a data center. The solution was to provide a signal reference grid and thus a “high frequency ground” that all of the electronic equipment used as a reference. Electronic equipment in a modern data center has evolved significantly since then and its proper operation is much less dependent on the quality of the grounding system. Proper grounding continues to be very important for all facilities for the safe operation of the electrical equipment and distribution system, along with surge and lightning protection. However, modern electronic equipment will operate properly with or without the high frequency ground reference.
