Hello Everyone,

My APS UPS working without any problem, and hybernates the QNAP after 5 minutes of power failure as seen in the screenshot.
As far as the other IPs into “Enable network ups master”- section is concerned, my understanding is that I would need an additional network-ups-server (perhaps, installed on a raspberry pi) so to be able to shut them down safely too.
Can you help out with ideas, please ?

Thanks, and Best,

Asen

Thank you @LTS_Tom.
I will check first the Smart- series of APC, they claimed it is done using a standard nic, and tcp- connection from web- interface, and Powerchute- app.
Best,
