I have two Eaton 9130i 1500VA (tower models).
They work fine. I drive them with a NUT server via USB and they are powered from two different mains lines and they are attached to an ATS.
I simulated a power outage with the force down command. All fine, all my devices went off and last also the UPSes shutdown themselfes.
But, when I restored the power supply they don't restarted but stopped in standby mode.
This is useless for me.
I also checked other posts and all settings look fine to me.
I know they are old UPSes (with new batteries) and that I bought them refurbished but I hope that someone can help me otherwise I must change them.
I also uninstalled the network cards but nothing change.
