6.6 Ethernet LEDs (J9)
Each Ethernet port has 3 LED signals that may be used to drive indicator LEDS. These signals are available on
an I/O connector. The signals also drive on-board LEDs. LED1 is the link indicator; an LED is connected between
this signal and +3.3VDC. LED2 and LED3 are speed indicators. A bi-color LED may be connected directly across
these two signals. It will display one color for 100Mbps and the second color for 1000Mbps speeds. Alternatively,
a separate LED can be connected between each of these signals and +3.3VDC for a 3 LED display. No external
resistors are needed with these signals.
