PCNS auto power on before UPS down

Anonymous user · ‎2021-07-08

Hello, I'm installing PCNS in my ubuntu server and i set the pc to shutdown when 15 min after the UPS enter battery mode.

If blackout happen, the UPS will enter battery mode and after 15 min the ubuntu pc will shutdown.

If the power back online after the UPS running out battery, the ubuntu pc can turn on automatically. But if the power online while the UPS still on battery mode, my pc cannot auto turn on.

Is it possible to make my pc auto turn on while the UPS still on battery mode when the power back online?

The PC is restarted by the BIOS settings and will only restart after power has been cut and restored. If you want the PC to be restarted you need to configure PCNS to shut the UPS down and in the NMC configure restart when AC is restored. After the PC shuts down the UPS will power down. The UPS will then see that AC has been restored and the UPS will power back up. At that time the PC will see that AC has been restored and restart.
