Home Assisstant Yellow POE not powering up, defect?

Hardware

Hello,

i got my home assistant yellow POE today, i assembled it as per instructions on the homeassistant.io page. After plugging the yellow into to my Aruba 2930F POE+ switch, nothing happens. I switched cables and ports to be sure, but nothing happens. I found a post about the CM4 maybe not correctly plugged in, so i removed the CM4 and plug it in again, i hear a light click on both connector sides, from visuals the connection looks good.

I did a visual inspection of the connector on the yellow and CM4 with a camera zoom, both look fine. The CM4 is a new device.

On my switch i notice a power draw around 0.7 watts on the port where the yellow is connected. No reaction on the yellow, not blinking or anything.

Is there a known issue with yellow and POE?

Have you resolved this? I am having the exact same problem. I even open mine back up to remove the CM4 and put it back in too.

It just took me 8 months to get a new CM4 in the hope the RPI was defect. Today i plugged in a new CM4 and again… nothing :frowning:

Same issue, i see around 0.7 - 0.8 watts power drawn from my switch without anything happening on my Yellow. I plugged in a 12V 3.8A power source to the barrel connector, nothing.
