July 23, 20214 yr Hi all, I have a Unraid server running on a Dell Poweredge T20 behind a APC Back-UPS ES 700. Everything is on it (vpn -home assistant etc). I noticed that when there’s a power loss ups is only able to keep server on for 2-3 minutes so I made the setting to shutdown gently as soon as it enter in battery mode. And here begin problems: If it a real powerloss o a fake powerloss (for example due to a thunder) server turns off and stays off until I manually switch on. It’s ok most of the time if I’m home but it’s very annoying if I’m on vacation. What’s are your suggestions? Duplicate vpn to use poweronlan?Change ups?Change some setting in unraid or in bios? Thank you in advance for your suggestions
July 23, 20214 yr Bigger UPS, as the battery ages it will lose capacity and you will have even less time. Maybe not enough to shutdown.
July 23, 20214 yr Even after you get a bigger UPS, you should still shutdown after it has been on battery for a short time. UPS isn't for running on, it is for allowing clean shutdown after power loss. If you let battery get too low, you might not have enough for shutdown if you lose power again.

Shutdown starts few seconds after power loss in order to have enough time to save everything.
