Ethernet cable providing power to MS130-8P switch

I just discovered that the MS130-8P switch I purchased was being powered by another Ethernet cable via POE. The external power adapter was not plugged in. 

 

I want to know which other Meraki switches support this feature and what its intended purpose is. I already understand that the best practice is the use the power adapter, but I want to know more about this feature and why it was built this way and what use cases there are for it, as well as what limitations there are.

 

I already opened a case with Meraki support and it was useless. The first few back and forth comments from support was demeaning and kept repeating that no Meraki switches can be powered by a POE cable, which was of course false since I was starring at such a switch.

Kind of a big deal

I have seen some smaller switches from other vendors where an end port can consume PoE to power the rest of the switch, but never a Meraki switch.  It would be useful as a repeater when you don't have local power, but yours may be a one off... 🤔

It's a bug and not intended behavior nor a supported feature.
