Hi, I'm about to switch from an x50-poe that I mounted on the ceiling (unfortunately it gives me problems with sporadic disconnections and restarts after almost 2 years) to a be25.
I found a diagram for a 3D ceiling support, what do you think, can it work well? 
I read on the internet that x60 is better in terms of power and speed, any advice on the matter? 
the 2.5gb port can be useful for me in the future if I think of updating my switches because I currently have an ISP with 2.5gbs thanks
