Hi all, hoping someone can help. I purchased an APC Smart-UPS (SMT1500IC), to help my home server shutdown safely in an outage.
First time using a UPS, I followed the basic setup steps as described in the box, but I’m seeing some really strange behaviour. The server is the only device connected to the UPS.
I booted the server up and entered the Bios. I was about to select the boot device manually when the server suddenly died and then kept trying to turn on and off in a loop constantly. I had to kill the switch on the PSU to stop the loop.
After flicking the PSU back on I tried to turn it back on but no joy, so I unplugged the power cable coming from the PSU and reconnected a standard power cable from the mains socket. This time the server POSTed, although it showed a "Chassis Intrude! Please Check Your System Fatal Error" message.
I powered down and reconnected the power cable coming from the UPS. This time the server would power up (I can hear the drives spinning up), but the activity light didn’t flash nor did the POST screen appear.
I powered down and swapped to mains power, at which point it boots up as expected.
I’m probably missing something obvious, but something clearly isn’t sitting right between my PSU and the UPS. Any guidance anyone could give would be appreciated !
PSU: SuperFlower Leadex Titanium 750w
UPS: APC Smart-UPS SMT1500IC (showing input 251v, output 223v)
