Turn off UPS enabled, shutdown command file configured.
The option to Turn off the UPS is enabled on the Shutdown settings page. A shutdown command file is configured.
When a critical UPS event, such as On Battery occurs, the following sequence is triggered.
- PowerChute reports that the UPS is on battery.
- After the shutdown delay configured for the On Battery event has elapsed, PowerChute then sends a
command to turn off the UPS. UPS turn off starts.
- PowerChute starts to execute the shutdown command file.
- After the duration configured for the shutdown command file has elapsed, an additional 70 second delay is
counted down before the operating system starts to shut down.
- The UPS will wait the amount of time indicated by one of the following, whichever is greater: Low Battery
Duration or Maximum Required Delay. These are shown on the UPS Shutdown page in the NMC UI.
- After this delay, a further non-configurable two minute delay is counted down.
- The UPS will then turn off after the user-configurable Shutdown Delay time has elapsed (this is configurable
on the UPS Shutdown page in the NMC UI).
It is recommended that the Low Battery Duration is configured to allow enough time for the shutdown command file
and operating system shutdown to complete. Ideally, the operating system should have shut down before the two
minute delay (step 6) starts to count down.
