Most simplest way i think use 4 diode (for complete isolation) with 2 different voltage adapter, like 24v adapter connected to main and 12v connected to ups. Combine pins with diodes and power unit from dc jack. When your mains fail you can see that /system health voltage level drop 24v to 12v. Unit work without interruption.

Or maybe you can use dc jack with poe in without diodes. Idea is same.
