Why are all LED's flashing simultaneously on my Smart-UPS SU, SUA, or SURT model?
LED's flashing simultaneously
All non-LCD display models (Line Interactive and Online), All Serial Numbers
All LED's, or the two center columns of LED's flashing simultaneously generally indicates a hardware failure.
Try to reset the fault by turning the UPS off/on or by performing a "brain dead" on the unit. To perform a "brain dead":
- Turn off the UPS
- Unplug the UPS from utility power
- Press and hold the off button again - You will hear a "click" and may see a brief flash of the LED's
