What a UPS does

– Provides battery power during outages so equipment shuts down safely

– Filters surges and voltage fluctuations

– Keeps critical systems running through short interruptions

Types

– Standby (offline): basic protection for desktops and small devices

– Line-interactive: regulates voltage, ideal for small offices and network equipment

– Online (double-conversion): continuously supplies clean power, best for servers and critical gear

Sizing

Add up the wattage of equipment you plan to connect, then choose a UPS rated comfortably above it (aim for around 70–80% load). Decide how many minutes of runtime you need, usually enough for a clean shutdown.

Best practices

– Connect servers, switches, firewalls, and NAS devices

– Don’t plug laser printers into a UPS, since their power draw is high

– Configure automatic shutdown software so servers power off gracefully

– Replace batteries every 3–5 years

– Test regularly

Beyond the UPS

For longer outages, consider a generator and whether your internet connection also stays up.
