One possible solution is to apply power to the two spare pairs of the
ethernet run. In that case no magnetics are required. My problem is that I
have a 802.3af compliant switch. It applies power to the signal pairs.
Looks like the Linear LTC4257 (and a few other parts) is all I need to use
the power supplied by the 802.3af switch at the far end. Digi-Key has what
I need except for magnetics. I guess my original statement was slightly
wrong in that I am not inserting power but utilizing the available power.
Not sure what the opposite end of the power inserter would be, power
remover?
