3.3.3.2 Ethernet Connectors (J4A/J4B)
There are four 10/100/1000 Mb/s full duplex Ethernet interfaces using the MC8641D Triple
Speed Ethernet Controllers (TSECs). Two Gigabit Ethernet interfaces are routed to the two
front-panel RJ-45 connectors with integrated LEDs for speed and activity indication. The other
Gigabit Ethernet interfaces are routed to P2 for rear I/O. These connectors use standard pin
assignments and are as follows:
