Hi, I initially purchased a Esp32-Poe and with this device when I connected to the Ethernet cable (apart from the power on led) two led lights came on. Being impressed with the device I have now upgraded to the "ISO" version and when connecting this to the Ethernet cable the power on leds come on but no additional leds to indicate that I am connected to the internet.
Therefore, can you please provide me with some guidance in how I can check if I am connected to the network/ internet. Thanks
The ESP32-POE-ISO still has LINK and ACK LEDs but boards come empty, you need to first download code that initializes the Ethernet. Try with one of the Ethernet demos, like this one for Arduino IDE:

Hi, I tried to running the Guithub code that initializes the Ethernet, and it didn't work and the serial monitor and debug note is as follows:
