I have a WAP371 running somewhat, only after switching from a conventional DC power supply to a POE+ injector. Before purchase I made sure it had a DC jack (marked for 12V), and I surmised that it could run on that. However, I got nothing but angry lights using a 12V power supply rated at 3.25A . (The quick-start guide mostly ignores the DC in jack, leading one to suspect that this power option never passed QC and reminding me of the infamous Intel 486SX. ) Is this a known problem?
I have tested a WAP371 with two different 12v 3 amp power supplies. Both powered up the unit and they functioned just fine.
I would suggest calling in and opening a ticket with one of our Engineers. Only guessing, but this could be some type of incompatibility with that brand. But that is getting out of my realm of experience.I mainly deal with the WAP itself, not the power coming to it.
Please let me know if I can assist in any way. If you open a ticket please give the responding Engineer a link to this support forum thread and then let me know the case number

Update: I was just looking here about another problematic Cisco device, and ran across this old WAP371 issue I posted. FWIW I tried 3 different commodity power supplies as well as my lab power supply, which I turned up as high as 14V with various current limits. The unit never did work at all when powered through the conventional DC jack. As for the performance on POE, after a couple of years trying to blame poor and intermittent performance on other network components, I finally gave up on it and have been running much more smoothly on a TP-link WAP since the switch. Official Cisco support has never expressed any interest in our satisfaction with their products. Erik, thank you for trying to help. Our WAP371 is now on the electronic trash heap.
