In all electrical and system components that support the proper functioning of the data centre, switches are usually invisible and hidden in the corner of the data centre facility. However, the rapid development of digitization today is changing the importance of switch equipment, and data centre facility managers must pay attention to the important role that switch equipment plays.

The role of data centres has never been so important as enterprises use big data generated by other forces, such as mobile computing and IoT, to drive competitive advantages, as the normal running time of the system is increasingly important for business success. Business interruptions not only affect productivity but also cause significant financial and reputational losses and affect market positions.

While generators provide back-up power in the event of short-term electrical interference, the optimal equipment requires a reliable distribution system for its normal running time, of which switches are the most important. Switching equipment consists of electrical isolation switches, fuses and circuit breakers for the control, protection and isolation of electrical equipment, which are directly related to the reliability of the electricity supply and provide power to the entire data centre facility. In many cases, power sources for grids and diesel generators are passed and controlled by switches. Thus, the time of shutdown of the switch equipment means the time of shutdown of the data centre.
