For example, during a power outage, you can keep key pieces of equipment running while you turn off other equipment. This feature allows you to save battery power. Each Dell Line-Interactive Rack model has two configurable load segments.
Configuring Automatic Start Delay You can configure a load segment to turn on automatically after the utility power returns, if it was shut down by: S The button S An external command with auto-restart option S Battery under voltage state S Automatic on battery shutdown command You can specify the restart delay time for each load segment: select zero seconds (0s is the default) to restart immediately, select 1–32767 seconds to delay for the specified time, or select Off.
Configuring Automatic on Battery Shutdown If set to Off (default), the load segment turns off only when commanded manually by the an external command, or through the display (Control > Load Segments). button, If set to zero seconds (0s), the load segment turns off automatically when the UPS on Battery state activates.
Configuring Battery Settings Configure the UPS settings for an installed EBM, including whether to run automatic battery tests and automatic restart configuration. Configuring the UPS for an EBM If the UPS is not configured for the EBM, the UPS reports less battery time remaining on the UPS front panel and to any remote software. You may receive a shutdown warning prematurely.
Running Automatic Battery Tests The automatic discharge test, enabled by default, runs during the transition from Float to Rest mode. After the test completes, the charge cycle restarts to completely charge the batteries and then continues to Rest mode normally. The automatic test runs approximately once every three months and does not run again until after three more Float to Rest mode transitions.

8 Troubleshooting The Dell Line-Interactive 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 are silent conditions that are recorded in the Event Log as status information, such as “Clock Set Done.” Events do not require a response. Notices and alarms are records of when events occurred and, if applicable, when they were cleared. S Notices, including active notices, are recorded in the Event Log.
Table 15. Typical Alarms and Conditions (continued) Alarm or Condition Possible Cause Action Battery test did not run or was interrupted. One of the conditions listed in “Running Automatic Battery Tests” on page 51 was not present. Resolve the condition, then restart the test. The UPS does not transfer to Bypass mode. The bypass utility does not qualify. Check the bypass utility. The UPS is receiving bypass utility power that may be unstable or in brownout conditions. Bypass mode is disabled.
Table 15. Typical Alarms and Conditions (continued) Alarm or Condition Possible Cause Action Battery Test Failed A weak battery string was detected during the last battery test. This is a warning notice. Dell recommends that you replace the batteries soon. A faulted battery string has been detected and as a result, the charger is disabled.
