8 Troubleshooting The Dell Online Rack UPS is designed for durable, automatic operation and issues alarms to alert you whenever potential operating problems occur. Usually the alarms shown by the control panel do not mean that the output power is affected. Instead, they are preventive alarms intended to alert the user. Active alarms and active notices are accompanied by an audible buzzer.
Event Log Menu From the Event Log menu, you can access the last 50 events, which includes events, notices, and alarms, arranged from newest to oldest. Events, notices, and alarms are logged in the Event Log when they occur and, if applicable, when they were cleared as follows: S Events are silent conditions that are recorded in the Event Log as status information, such as “Clock Set Done.” Events do not require a response. S Notices, including active notices, are recorded in the Event Log.
