Case 1: Power Failure with Enough UPS Runtime Remaining

This example describes a power failure occurring when the UPS has enough battery run time remaining to shut down the system safely. The example assumes the following delay times are configured:

Event or Parameter
Configuration.
Delay Time
UPS On Battery In the "Event Actions" dialog box, click Options... for the Shut Down Server action 120 seconds (instead of the default value, 300 seconds)

Shutdown begins 120 seconds (2 minutes) after the UPS switches to battery power, unless normal power returns.
System Shutdown Starting In the "Event Actions" dialog box, click Options... for the Shut Down Server action. 60 seconds

This shutdown delay allows time for a user-specified command file to execute.
UPS Turn Off Delay Select UPS Shutdown Parameters... from 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.)

In addition, the example assumes that other relevant events and parameters are configured as follows:

Event or Parameter
Configuration
Delay Times
UPS on Battery event notification Use the "Notify Users" dialog box for the UPS on Battery event. Wait 5 seconds before notifying. Notify every 30 seconds
Run Command File (See How to Run a Command File.) Use the "Run Command File" dialog box for the System Shutdown Starting event Wait 5 seconds before executing
UPS Wakeup Delay (Time) and UPS Wakeup Delay (Capacity) Use the UPS Shutdown Parameters... option of the Configuration menu. UPS Wakeup Delay (Capacity) is configured as 15%, and the UPS Wakeup Delay (Time) is 0.

See Narrative of the Case 1 Shutdown for the sequence of events and actions during the shutdown.
