some of UBNT products like Nano station M5 has two LAN port which you can enable PoE pass-through for it. It allows you to get power from the second lan and power on other devices. I used this feature for Some IP cameras and also NSM5. It was a nice experience.

Now I want to know, Is there any MT products exist which has this feature?
I think MT can add this feature to OmniTIKU-5HnD because of number of lan ports.
If this is not a good idea, Any reason to prove it?
