Chapter 3: Connecting the cpuModule 47
Ethernet (10/100/1000Base-T and -TX) Connector (CN20)
This connector provides a 10/100/1000Base-T Ethernet connection. Table 23 provides the pinout of the
Ethernet connector. For 1000Base-T, all four pairs are used for transmit and receive.
To use the onboard 10/100/1000 Ethernet controller, Ethernet must be enabled in the BIOS.
When enabled, the multi-color LED will blink to indicate an Ethernet connection. For more information,
section on page 71.
