Beeping Continuously
CyberPower UPS
Severity: ModerateWhat Does This Error Mean?
A CyberPower UPS beeping continuously usually means it has switched to battery power, the battery is critically low, or the load is too high. Check whether your mains power has been cut, then unplug non-essential devices to reduce the load.
