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

[Hideaki]

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

/sys/class/gpio

/sys/class/gpio is no longer working in Jetpack 6.0. You need to do this instead:

gpioset 2 15=1

Check my reply. I believe you have a networking/IP misunderstanding.

Hi Alan and Alberto.

I set the gpio parameters as the reply, it worked.
Thank you for your advises.
