Ethernet (10/100/1000Base-T and -TX) Connectors (CN20 and CN30)<br />
This connector provides a 10/100/1000Base-T Ethernet connection. Table 25 provides the pinout of the Ethernet<br />
connector. For 1000Base-T, all four pairs are used for transmit and receive.<br />
To use the onboard 10/100/1000 Ethernet controller, Ethernet must be enabled in the BIOS.<br />
When enabled, the multi-color LED will blink to indicate an Ethernet connection. For more information, refer to<br />
the Multi-Color LED section on page 70.<br />
