Descriptions
Active low indicates 100M link is good. Blinking indicates 100M activity.
Active low indicates 10M link is good. Blinking indicates 10M activity.
LED_LN[2] is active low, indicating 100M utilization. Utilization indicator is not per
port basis, but rather per segment basis. The LED_D[0:7] indicates percentage of
utilization.
