How to fix OPTI-UPS Power UPS that does not power up?
- MMarissa ChungAug 2, 2025
If the OPTI-UPS UPS does not power up and has no audible alarm, try the following: * Ensure the On/Off button is pressed long enough until the UPS turns on. * Check the wall socket and test the input line voltage, as there may be no incoming line or very low or very high line voltage. * Plug in the input power cord if it is not plugged in. * Reduce the load and reset the circuit breaker if the rear panel circuit breaker is tripped.
