Unraid not restarting after clean shutdown by APC UPS

[crabsticks]

Hello, 

 

I'm having a strange issue I can't figure out and I'd appreciate any advice. 

I have bought an APC UPS, connected it to unraid and set up the daemon fine, if I unplug the UPS from the mains it shuts down cleanly at the battery level I've selected. When I then plug the power back in the UPS status light turns solid green but the server doesn't power up. If I press the power button it starts fine. 

 

However, I have the bios set correctly to boot when power is supplied. If I plug the server into the mains without the UPS and flick the power at the wall outlet it powers up and boots unraid.

That's normal because UPS continue power up Unraid.

So how do I get my server to power back up automatically when the power is restored please?

Some UPS have an option to power off after some time on battery and power back on when power is restored, that's the only option.

So why isn't that happening? Have I missed a setting somewhere? 

[JorgeB]

That's a UPS option, it might not exist in yours.

You should check the setting "Turn off UPS after shutdown:" does UPS will shutdown and resume once power return.

But if AC mains resume before that time, then UPS power still never interrupt to trigger PC automatic power on.
