Oak-4D initial power through PoE module red light

Hey @Floris ,
Thanks for trying via adb devices.

Could you try plugging out all cables and then plugging in only the 30W USB-C PD powerbrick, followed by plugging the ETH cable directly into your non PoE switch (bypassing the PoE injector).

I would like to make sure that the PoE is bypassed completely in case there is any issue with the device or the injector.
Thanks for your patience,
Filip

Hey Filip,

I've tried this and the results are still the same. My 30W USB-C PD powerbrick is plugged in, and the ETH cable is plugged directly into the router and the list of ADB devices is still empty.

Floris

Hey Filip,

Is there anything else I can try to make this work? Or any possible next step you'd suggest?

Apologies for the late reply. We are looking into it. If no solution is found, we can RMA.

Thanks for your patience.

Hey @Floris
Could you send a video of your setup and any lights coming from the device after it's powered by the 30W USB-C PD supply?

Hey Filip,

I've attached 2 videos of the various setups that we've discussed before. I have a third for the setup of using the POE but am having some issues compressing this to a size I can upload. However I figured the below two videos should already be of use

One thing not visible on the video - after the light turns off after blinking red - if you wait about 20s, nothing happens? I'm guessing it's the cable that is causing issues - can you try a different one (C-C) that supports 30+ watts?

Thanks,
Jaka

Indeed after the light turns off, 20 seconds later nothing happens and I am unable to list the device through ADB devices. I run into the same issues when I use the PoE injector + ethernet cable. I will find a different USB-C cable to try, however this cable has no issues on any of my other devices. That being said, i realise how tech can be so I will update this thread with a video of a different usb-c cable + 20 seconds of extra footage to showcase whether anything happens

Hey Jaka,

This is a video with a different USB-C to USB-cable attempt. I've also shot the video longer to show nothing happens after 20 seconds of being plugged in and off camera I did an "ADB devices" check and found nothing on the network. Does this showcase anything further? I would really love to get the camera to startup properly and am not quite sure what else to try in that regard

Hey Jaka,

Would it be possible for someone to take a look at my above comment? I'm really hoping to get this functional in the near future.

Hi Floris
I think we will need to replace the device. It might be a deeper SW issue. Can you send a https://www.luxonis.com/rma request? We'll get you sorted ASAP.

Thanks,
