Troubleshooting
The Dell Tower 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.
Accessing Alarms and Conditions
The control panel provides troubleshooting information from two main menus:
SUPS Status menu: access to all active alarms
SEvent Log menu: access to the most recent 50 events, which may include active and closed alarms
UPS Status Menu
From the UPS Status menu, you can access the following screens for troubleshooting information:
SStatus summary screen: The status summary screen provides information on both mode and load. When there is a critical alarm, the status summary screen changes from its normal white text on a blue background to dark amber text on an amber background.
SNotice or alarm screens: A separate screen appears for each active notice or alarm. If there are no active alarms or notices, the display reads “No Active Alarms.”
SBattery status screen: The battery status screen indicates the battery charge mode, the percent the battery is charged, and the runtime with the present load level.
NOTE: When an alarm is active, the control panel automatically displays an active alarm screen unless the screen lock is enabled by the user.
To access troubleshooting information using the UPS Status menu:
1Press the 
button for one second to go to the main menu selection.
2Press the 
button to access the UPS Status menu.
3Press the 
button to access the UPS status summary screen.
The UPS status summary screen provides load information. The status icon indicates the UPS operating mode (see Table 4 on page 32).
4Use the 
button to scroll through the active notice and active alarm screens.
5After scrolling through all alarms, press the 
button to access the Battery Status screen.
