diagnostic LEDs and a card edge serial port connection. This serial port is used to set the initial
configuration of the card and can also be used for debugging.

3.3.1 LED Indicators
Most of the small LED indicators are currently reserved for factory use.
LD7 indicates the power status of the card. This LED should always be illuminated Green. If it is off,
this indicates a problem with the power supply of the card.
LD10 should always be off during normal operation. If this LED is Red, this indicates that the card is
not booting properly.
LD6 will illuminate Green where there is no Ethernet link. It should be off under normal operation.
