There you have 2 cable pairs that can be used to provide 5V/GND on 4 unused cables. All you then need is something like this

And then everyone can save the $2 for a passive PoE splitter: http://www.i4wifi.eu/EU-230V-powering-1/...itter.html
Simply route 2 traces from Ethernet jack to AXP803 and you're already done.
I don't like this method. If somebody unaware of this arrangement and plug in 48V, the whole board will be toast. Prefer to implement in "right" way.
I would better read the specs and think about how 'Resistive Power Directory' works. Thanks.
