An uninterruptible power supply (UPS) system provides power to the server in case of loss of
electrical power from the main building power. The UPS is rated in volt-amps (VA) which is the
total power it can handle and the time it can run the server, usually the time required for the
operating system to close all running applications, gracefully shut itself down, and turn off the
server.
