Greetings!
After acquiring a used Eaton 5PX1500 UPS, I've ran into a rather strange issue with it; both hot-swap power supply modules of my server lose power when the Eaton UPS drops to battery no matter what outlet/group they are connected to. Other devices attached to the UPS stay online normally and ALL outlets have been measured to output correct voltage and frequency when on battery. The server has absolutely no issues when attached to 25 year old APC Smart-UPS 1000.
Furthermore (and this is the best part), if my Harman-Kardon amplifier in the server rack, which is also attached to the Eaton UPS, is turned on, the server's power supplies recover and the server is turned on and stays on, even if the amplifier is turned off again.
What could possibly be the issue here?
