OAK-D LR CAMERA STOPPED WORKING

Hi everyone,

I am writing this post to try and figure out why my Camera has stopped working. I was out of the lab for a month and had disconnected the usb from the camera and placed it away. It was working a month ago but upon reconnecting it now it does not seem to work.

The depthai_viewer does seem to run but cannot detect a device

the rgb_preview.py example throws the same error

Manage App Execution Aliases.

(base) PS C:\Users\Purdu\depthai-python\examples> python .\ColorCamera\rgb_preview.py

Traceback (most recent call last):

File "C:\Users\Purdu\depthai-python\examples\ColorCamera\rgb_preview.py", line 24, in <module>

with dai.Device(pipeline) as device:

     ^^^^^^^^^^^^^^^^^^^^

RuntimeError: No available devices

(base) PS C:\Users\Purdu\depthai-python\examples>

I am attaching some pictures and videos of the entire setup for some guidance on what could be done for the same.

entire-setup-usb-and-poe.mp4

4MB

first-connection-no-poe-yet.mp4

2MB

Some guidance on this would mean a lot

The device should work on USB only. Blue light should be present on the bottom and device should be detectable with under devices.
POE:
And I don't see any lights indicating the power is delivered to POE port. Why not use ETH only or USB only?

Thanks,

Hi, there is a yellow/green light for the POE under the desk when I plug it in (the power socket is under the desk).

I had connected the usb and the POE before break and it was working with that setup. Are you saying it would work just with the usb connection from the camera to the computer?

Also, I was curious on how to disconnect the ethernet from the camera. The second part of the top half does not pop off and the only way to connect the ethernet is via the pin facing towards the second part(thus not making it possible to grab it to remove)

Yes. Device should be found on USB only.

Not sure what you mean.

I see,

I was referencing this

The grey part will not come off from the other side and the ethernet pin is facing that side. As such I am struggling to disconnect the ethernet port.

Any suggestions for that would be appreciated as I'm sure other users might have experienced similar problems. I tried giving it to other teammates but they weren't able to get it out either.

Also, would I need to do a reinstall of any of the libraries or a clean boot if and when the POE is removed
