Case 2: Power Failure with UPS Run Time = Low Battery Signal Time

When the UPS is supplying battery power to the connected computer system during a power failure, PowerChute plus detects when remaining UPS battery runtime equals the UPS Low Battery Signal Time. When this occurs, PowerChute generates a Low Battery Condition event and begins shutting down the system.

The UPS Low Battery Signal Time parameter ensures that PowerChute plus will shut down the system while the UPS can still support the attached load during the shutdown. You configure UPS Low Battery Signal Time through the UPS Shutdown Parameters... option of the Configuration menu.

Case 2 assumes the following delay times are configured:

Event or Configurable Delay
Configuration
Delay Time
Low Battery Condition event In the "Event Actions" dialog box, select the Low Battery Condition event, and click Options... for the Shut Down Server action 30 seconds

Begin shutdown 30 seconds after the Low Battery Condition occurs.
System Shutdown Starting delay In the "Event Actions" dialog box, select the System Shutdown Starting event, and click Options... for the Shut Down Sever action. 60 seconds

This shutdown delay allows time for a user-specified command file to execute.
UPS Turn Off Delay Select in UPS Shutdown Parameters... on the Configuration menu 20 seconds

PowerChute plus instructs the UPS to wait this period of time before it turns off power to its outlets. (This cannot be configured for a Back-UPS.)

See Narrative of the Case 2 Shutdown for the sequence of events and actions during the shutdown.
