Gigabit Ethernet Interfaces
The Ethernet wire cabling interface is implemented using five 8-pin, female, RJ45 connectors.
Connectors J4A - J4D are implemented as channels 1 - 4, and connector J5 is implemented
as channel 5. As the Gigabit Ethernet controller is able to automatically detect the cabling con-
figuration and Ethernet standard in use, the pinout of the individual connectors is a function of
the implementation.
The following figure illustrates the pinout and LED positioning of the J4 and J5 connectors.

The Ethernet connectors are realized as RJ45 connectors. The interfaces provide automatic
detection and switching between 10Base-T, 100Base-TX and 1000Base-T data transmission.
Auto-wire switching for crossed cables is also supported.
