Just thought of something concerning PoE stuff that we briefly talked about earlier this morning.
I mentioned that ethernet uses only 2 pair of wires ( 4 wires )... that's true for 10base-t and 100base-t.... but 1000base-t ( gigabit ) actually uses the full 4 pairs of wires. This would then sound like that you couldn't use PoE on a Gb ethernet connection but they can co-exist also since they are using different frequencies for data and power... ie phantom power methods so they don't interfere with each other.
So it didn't really make a difference with what I said... just correcting or adding to what I mentioned about the number of pairs being used since you are using or planning to use Gb ethernet in your wiring and didn't want you to be concerned with using a PoE switch if you go that direction.
