Issue with OAK-FFC 1P PoE Connection

Abhishek-Nair

Hi,

Our company recently bought OAK-FFC 1P PoE Board along with OAK-FFC IMX582 Camera board. After connecting the mentioned camera with PoE board and using TP-Link TL-POE16OS PoE+Injector, we noticed the board powers up immediately, all the red lights provided on board, i.e 5V, PG and nRST Board are glowing along with two green LED's on the SoM Board, whereas lights provided on the Ethernet connector is not glowing at all. We have other OAK-1 PoE Camera's with us to test the setup and its working fine on the same Injector and using same cables, whereas this PoE board doesn't show any communication LED blinking on the ethernet Board.

We tried following things to troubleshoot:
1. Tried to ping on the following IP: 169.254.1.222 and we got response as

PING 169.254.1.1 (169.254.1.1) 56(84) bytes of data.

From 169.254.1.30 icmp_seq=1 Destination Host Unreachable

2. Disabled WiFi to make sure that network was not creating conflict, In parallel we tried to test the same setup with OAK-1 PoE camera and everything works.

3. Connected USB to test out the camera and SoM board and it was working fine, we are able to stream data using depthai_demo.py script.

4. We tried running depthai-experiments-master/gen2-poe-tcp-streaming/oak.py and it was showing

with dai.Device(pipeline) as device:

RuntimeError: No available devices

Also we tried script to initiate pipeline and address the device under 192.168.1.222 IP, we got following response:

with dai.Device(pipeline, device_info) as device:

RuntimeError: Failed to find device after booting, error message: X_LINK_DEVICE_NOT_FOUND

5. Tried to update bootloader and depthai:

After changing the boot switch to USB mode and connecting the USB cable, we utilized the device_manager script under depthai-python/utilities to upgrade the Bootloader, before and after update the upgraded version remains 0.0.27 and depthai modified to depthai-2.25.1.0

6. changed the LAN Cable to see if that was causing issue

After all these process, we can't see any communication LED blinking on the ethernet port on the PoE Board side. Kindly Suggest what to do.

Hi @Abhishek-Nair
Did you select NETWORK bootloader when updating the bootloader? Other than that, you have pretty much done everything you can do, looks like a faulty RJ45 connector:

Abhishek-Nair whereas this PoE board doesn't show any communication LED blinking on the ethernet Board.

Ill check tomorrow at the office.

Thanks,

Hi Jaka,

Thanks for the feedback, today i retired flashing the Factory Bootloader selecting Network as Option and it worked. I am able to ping to device.
