Network configuration on the Arduino PMC is not working

I want to communicate between the Arduino Portenta Machine Control (PMC) and my PC using a LAN cable. However, the network configuration on the Arduino PMC is not working correctly. I only have the hardware and do not have an Arduino PLC license, so I am developing with Arduino IDE.

Here's my code:

byte mac[] = {
  0x90, 0x2E, 0x16, 0xF4, 0xED, 0xB4
};
IPAddress ip(192, 168, 0, 180);
Ethernet.begin(mac, ip);

Physical connection: Arduino PMC - Router - My PC

Additional Info:

  • When the LAN cable is connected, the green light on the Arduino LAN port does not turn on.
  • RS232 and Wi-Fi are working fine.

Is this a hardware issue with the LAN port?

please help me!

Sorry, there isn’t enough information here to assist you. Posting a correct, annotated schematic will go a long way in helping you get an accurate answer. Be sure to show all connections, power, ground, power sources, and note any leads longer than 10 inches (25 cm). Also, please post your complete code and specify what isn’t working.
