I have a hAP ax3 (pictured) - Exact model C53UiG+5HPaxD2HPaxD from RouterBoard in system
Notice where the power goes in, and where the white ethernet (ether1) is - this seems reversed to every other image of this router I can find - including the Mikrotik site.
It was bought new, the model/Serial all match, the router is also sure it's a hAP ax3
Has anyone else come across this mirror board version ?
The side with the MikroTik branding is the bottom of the device. You are the one who placed it upside down.
Damn lol - that makes sense!!
Thanks for pointing it out 
Still waiting for the config...
This exchange just made my Friday. Thank you both! 
Was the hammer in the photo, intended to fix the problem?
Glad it made you smile
It made me slap my head lol
I can only put it down to the fibre provider turning up at the end of the day to install and we were rushing to get the new router in before we had to leave.
No, it was my partners daughters house and they have been doing some diy there.
This reminds me of David Jones saying that "The electrons will fall out!"

It should also have a stand that clips in the recess around the Mikrotik logo.
The stand can also go on the end to give you a vertical mount so you have more real estate for other things.
