AH1100x2 - PoE powering

Hello;

I’ve got a question to hardware people:
MT 1100AH x2 contains port eth13 as Poe.
I want to power on through this port, with 24V supply.
Q1: Can I power it on from 100MBps/ passive PoE supply?

Also, there is information: RJ45 Gigabit Ethernet 1000Base-T port with PoE (Ether13) = Jumper 5.
Q2: Should I disable or enable anything onboard before connecting passive PoE to port 13? How jumper is set default?

And info: The device does not support power over datalines.
Q3: It mean, that this port cannot be uses as GBit?
Or can be used as GBit, but with no power supplying?

I’ll be so kind for any useful information, before I will burn it :wink:
I have bad experiences with powering on through PoE on MT boards :confused:
