Make sure the firmware for the 750UP is up to date. I know I had some issues with 750UPs that had current RouterOS at the time, but was still running firmware that was pretty old. I honestly don't recall what firmware version it was, but it seemed to clear up the problem I was having.
Current firmware version on RouterOS 6.27 is 3.22. I am almost positive there was a firmware version out there that caused issues with the PoE functionality. Please note, I was also doing this on a test bench, no on anything in the field.
