Power & UPS
UPS load planning
A UPS is for safe shutdown and short continuity, not for powering every device on a desk during an outage.
Prioritize critical devices
- Battery-backed outlets should favor modem, router, small switch, NAS, or desktop gear that needs safe shutdown.
- Monitors, speakers, printers, chargers, and decorative devices usually shorten runtime without helping recovery.
- Use surge-only outlets for devices that do not need battery power.
Estimate load honestly
- Use UPS display watts, device labels, or a meter when available.
- Plan around conservative runtime, not the largest marketing number.
- Reduce load before assuming the UPS battery or unit is bad.
Stop for safety signals
- Stop immediately for heat, swelling, odor, sparking, leaking, or overload alarms.
- Do not plug heaters, laser printers, or high-draw appliances into a UPS unless the manual explicitly allows it.
- Get qualified electrical help for outlet, breaker, or wiring problems.
