I was forced to renew my “not so nice looking" LAN Socket for my UniFi AC-PRO ceiling mounted. So the new socket was not really a big task, but I also need to change the LAN cable from the socket to my Access Point. And now the fun begins. I tried to release the AC-PRO from the ceiling mount. After I few tries I figured out - no chance - I will not be able to remove the AP from the mount.
So let's have a look into the Manual. Ahhhh there is a small hole on the top of the AC, which can be used to unlock the AP from the ceiling mount.
My problem was that I was not able to reach the small hole, because my AP is mount close to a wall. So long story short. The solution is to grab a cable tie and form it a little bit.
Then push the cable tie to the small hole in your UniFi AC Pro, and now you will be able to release the AP from the ceiling mount.
That's it - Have now fun unlocking your UniFi AC Pro. :-)
