J1,J2 - Ethernet Port Connector

The Ethernet connectors on the MPC8349 (J1,J2) are both Twisted-Pair (1000-Base-T)
compatible connectors. They are implemented with a 90
internal magnetics and two LEDs (indicating communication speed), signals of which are
described in Table 5-19. "J1,J2 - Ethernet Port Interconnect Signals" below. These connections
are on the front panel. For location, see Table 1-1. Green LED indicates 1000Mbit Data rate,
Yellow LED is lit when 100Mbit Data rate mode. .
