A UPS is an Uninterruptible Power Supply. It’s basically a huge rechargeable battery that provides emergency mains power to keep the most important equipment (the servers) running for a short while during a power cut. They typically do not last any longer than 30 minutes unless you’ve bought a really expensive one.
