Oak-4D initial power through PoE module red light

Floris

Hi,

My hardware is shown in the screenshot. It's the Oak 4D-AF + PoE(+ injector) module. Plugging this module into the main power supply only and then the Oak 4D yields only a series of red flashing light. From the instructions this indicates a potential power incompatibility. Given the unit I'm using for power is the PoE + injector that is rated for the 30W, and I've tried multiple different outlets just in case; is there anything further I can test or is there an indication as to why the power incompatibility might be?

The injector is in fact passive so the red light is expected. You can safely ignore it.

Hi @Floris
Apologies for late reply. As long as your POE injector is 802.3at, you can safely ignore the red light. I will assume the injector you are using is not passive, so it is rather strange you are getting the low power warning. Let me check with the team.

Thanks,

Hey Jaka,

No worries on the response time, and apologies on that front from me too. Understood on the injector being passive. That's good to know. I am however still facing issues with the initial registration of the Oak 4 D unit. After the red ring flashes for a few times it stops and fades, after which no lights are burning. From what I've read should it not continue to a blue light despite the initial red light if there is enough power? Further, I've tried using oakctl to discover the camera. My setup at the moment has one of the ethernet cables from the PoE+ injectors to the camera and another ethernet cable from the injector to my desktop computer running windows. I have Oakctl installed and operational but when running $oakctl setup - or connect there's no ability to connect to the camera or discover it.

Would you have any advice on continued troubleshooting/setup?

I'm thinking it has to be power still.
Do you have a power brick with PD that can supply 30W? Try using that to power the device. LED should be blue after the bootup sequence is complete.

Thanks

Hey Jaka,

I do have a powerbrick with PD that can supply 30W. However the LED light does the same thing. Flashes red multiple times and then turns off. If it's of use I'd be happy to attach further pics or videos?
