Most of the time this is due to a malfunctioning/dead battery. Feel free to contact our technical support specialists, and they will properly diagnose the problem for you.

First, check to see that the phone cord is securely connected to the UPS and the computer. Next, check to see if you can get a dial tone when you bypass the unit. If you are able to get a dial tone when bypassing the unit, please contact technical support. If you are unable to get a dial tone when bypassing the communication protection ports, please contact your phone company.

To run a self-test, open the Power Panel software and then click “Initiate Self Test”. Another way to perform a self-test is by turning off the circuit breaker for the circuit the UPS is plugged into or unplugging the unit from the wall.

CyberPower Smart App Online Series UPS systems include a Generator Mode setting specifically designed to work with generators. With varying loads, the frequency output from generators can be erratic. This erratic output can make it difficult for a UPS without a Generator Mode setting to recognize the input power, causing the UPS to function on battery power only. With Generator Mode, the UPS can automatically adjust to frequency fluctuations and maintain a full charge of the batteries.

The internal cooling fan will only run when it is required. CyberPower UPS systems utilize an internal thermometer which activates the fan when the temperature exceeds a certain threshold. When the UPS is running idle (not using battery power), it is completely normal for the fan to not be running. The exception is with Online units, models that begin with “OL”. Their cooling fans will run ALL the time.

The UPS will charge the battery whether the unit is turned on or turned off.

The front-mount rackmount ears are specifically designed and tested to hold up their own weight in both a two-post and four-post rack enclosure. Rear supports are not needed, but users can install them if they wish.

CyberPower Systems encourages environmentally sound methods for disposal and recycling of its UPS products. Please dispose of and/or recycle your UPS and batteries in accordance to the local regulations of your state.

UPS systems are designed to make beeping noises to alert users that the UPS is having difficulties by providing quick responses to specific issues.

A UPS contains batteries that have battery posts, terminals and related accessories that contain lead and/or lead compounds as well as other chemicals known to the state of California to cause cancer and birth defects or other reproductive harm.
