Ethernet Pinout Diagram

Yellow LED:

  • Active when operating speed is 100Mbps
  • Inactive when operating speed is 10Mbps or when not connected

Green LED:

  • Active when valid link is detected
  • Blinks when activity is detected
  • Inactive when not connected


 IMPORTANT: The auto-MDIX feature is always activated. This feature automatically detects the required cable connection type (straight or crossed), and configures the connection appropriately, removing the need for crossover cables. In order for auto-MDIX to work correctly, auto-negotiation (auto speed and auto duplex) must be enabled on both sides of the link. Note that auto negotiation is always active.
