Question about Computers & Internet
The main problem here is more likely due to the not quite sinusoidal output of the UPS and the power adapter.
If I owned this unit myself, I would probably just put a large electrolytic capacitor across the 12V coming out of the power supply going into the POE injector [POE = Power Over Ethernet] to smooth out the transition and get rid of the ripple during UPS Up Time.
50V 4700uF capacitors are pretty common and therefore inexpensive, so I'd probably use something like that.
It's not the prettiest solution, but it should work!
