LED and audible alarm troubleshooting
This UPS is designed for durable, automatic operation and also alerts you whenever potential operating
problems might occur. Usually the alarms shown on the control panel do not mean that the output power is
affected. Instead, they are preventive alarms intended to alert you of a possible condition.
The following table describes typical alarms and conditions. If an alarm appears with a service code, contact
HP technical support ("
