I was asked today if my switches were passive / active.
I searched quite a lot and only found 1 definition which was
"Active PoE has active components inside and it is able to transfer power up to 100 metres. Passive PoE uses free wires in the Ethernet cable and sends the equipments power along them to the far end. Passive PoEs range is about 30 to 40 metres / 100-130 ft that covers the needs of up to 90% of users according to our statisitics"
so I'm guessing these are not common phrases.
I have dell powerconnect 3448p with dell eps 470
going off the description above I would say we are using passive POE however can anyone else expand a bit on the differences?
