Ok, tell me what I am doing wrong. I am trying to get my laptop working with 1 GPeR in line. My laptop does not support PoE, so as per the manual, I should remove the 2 out-side poe jumpers.
In case if the destination device does not support or requires PoE powering, the power passthrough can be
disabled manually by removing both jumpers on the PoE out side.
When the (2) OUT jumpers are removed, I cannot get anything to work. The GPeR never lights up. The switch reports poe “searching”.
When I put the jumpers back, I still get no lights on the GPeR. However, if I briefly connect a POE device on the GPeR OUT, like a LHG60G, I get lights on the GPeR, and I can then connect my laptop and it works! (very well too!). However, this won’t work if the switch reboots, so what am I doing wrong?
I have tested this with several different GPeR units, all do the same thing. I have tried this on an HP (3500yl) & Extreme (X460).
Here are 3 photos that show it will not power up on it’s own.
Photo 1: GPeR is connected to 802.3af switch with tester in adjacent port proving power is available. GPeR does not power up. No LED light.
Photo 2: GPeR is connected to 802.3af switch, tester is moved to the GPeR OUT and it now powers up.
Photo 3: Tester is removed, GPeR stays powered up. I can then connect my laptop and it works.
Removing the 2 OUT jumpers does not fix the problem, I can’t get it to power up at all then.
The 802.3af standart needs to negotiate some things with the receiver device. It works well, if you are connecting through the GPeR to some 802.3af compatible device. But if you are only powering the GPeR itself, with disabled PoE passthrough, it will not work, as the GPeR itself can only be powered by Passive PoE injector. We will clarify this limitation in the GPeR documentation
