Monday at 08:50 AM1 day HI,Recently I have added a UPS for my Unraid server - APC Back UPS BX950MI.Below you can check my current settings. All looks fine to me, but as soon as I cut off power to the UPS, Unraid shuts down immediately.Additionally I got this Alert:UPS AlertEmergency! Batteries have failed on UPS FuxlNAS. Change them NOWI'm grateful for any help.P.S: Unraid 7.3.2. Internal boot enabled. diagnostics-20260817-1058.zip Edited Monday at 08:59 AM1 day by Fuxl66
Monday at 09:09 AM1 day Community Expert You should run a test program on the UPS (on Windows or something) checking the batteries.Maybe they are really worn out (they do not last forever, 3-5yrs are good for APC build ones to my experience).Prepare to buy new ones and exchange them, then reload and cut power again to check if they now work.Another possible reason for the shutoff maybe an overload. UNRAID usually shows you the percentage used on the UPS, make sure you have quite a lot of reserve.the current load of 13% make me sleep tighter and more calm...
Monday at 09:30 AM1 day Author Thanks for your reply.You can see in my screenshot a load of 12% (62W).I am going to check the battery, but it´s new

Could be the ups protecting your equipment from it's failed batteries by doing immediate shutdown. I suspect when that alarm clears it will do what you want.
