PoE ports don't output power.(reServer Industrial J3011)

I got a “reServer Industrial J3011” and connect a network camera via PoE port,
The pc doesn’t output power.
I think Poe is available only to be connected.
I don’t know what to do.
Is there a way to get Poe available?

Hi Hideaki,

Just in case you didn’t see this …

Usage
Before connecting PoE cameras, you need to enable the PoE function for the 4 Ethernet ports. Enable it as follows:

sudo -i
cd /sys/class/gpio
echo 315 > export
cd gpio315
echo “out” > direction
echo 1 > value
