Why a UPS? In general, a UPS protects IT equipment and other electrical loads from problems that plague our electrical supply, performing the following three basic functions:1. Preventing hardware damage typically caused by surges and spikes. Many UPS models continually condition incoming power as well.2. Preventing data loss and corruption. Without a UPS, devices that are subjected to a hard system shutdown can lose data completely or have it corrupted. In conjunction with power management software, a UPS can facilitate a graceful system shutdown.3. Providing availability for networks and other applications while preventing downtime. In some cases, they provide enough battery runtime to ride through brief outages; in other cases, they provide hours of runtime to ride through extended power outages. UPSs are also paired with generators to provide enough time for them to power up. Introduction T HERE'S A   L OT T O S EE I N T HIS H ANDBOOK.
