The grounding system is a basic condition for correct operation not only the servers, but any other electrical equipment. The reliability of data center servers and security of staff depend on the literacy of grounding design.

When making design of data center grounding system, you must take into account the power of protected equipment and the interposition of premises.In comprehensive data centers the grounding system is the multicomponent engineering construction. There is a tend in such systems to allocate a separate circuit of lightning protection, which wires profiles could withstand the stresses arising from a lightning strike.

A data center grounding bus is constructed in that way as to ensure uniform distribution of capacity and to avoid situations when, due to a poor grounding, an accident on a single data center node leads to a failure of other nodes. Also, this bus provides protection for data center personnel from electric shock and electromagnetic radiation of equipment.
