What to do if the overload LED is illuminated and the IBM UPS emits a sustained alarm tone?

The overload LED is illuminated and the IBM UPS emits a sustained alarm because the connected equipment is drawing more VA or Watts than the UPS can handle. To resolve this, disconnect nonessential equipment to reduce the load. Note that the UPS will continue to supply power as long as it's online and the circuit breaker hasn't tripped, but it won't provide battery power during a utility voltage interruption. If a continuous overload occurs while the UPS is on battery, it will shut off output to prevent damage.
