Simple question. On a 100 mbps POE switch, can it do full duplex? If 2 pairs are used for power, wouldn't that limit connected network devices to half-duplex?

Can a POE switch do full duplex GBE over copper? How?

Standard UTP ethernet cable has 4 pair. One transmit, one receive and two unused pair.

So yes, you can do POE and full duplex.

And you can do POE with gig-ethernet providing that you aren't using all four pair for the ethernet signal.

It appears my RCCD was mistaken. I cross referenced your comment with the following WIKIPEDIA article:http://en.wikipedia.org/wiki/Fast_Ethernet

Per that article, "Each network segment can have a maximum distance of 100 metres (330 ft). In its typical configuration, 100BASE-TX uses one pair of twisted wires in each direction, providing 100 Mbit/s of throughput in each direction (full-duplex). See IEEE 802.3 for more details."

Thanks for your reply!
