2.7 LED Indications

The WAFER-7850 is equipped 4 LEDs to indicate the system status.
There are two LEDs on the D6. The upper green one indicates the IDE
status.
While the IDE is transferring data, this LED is in flicker. The lower
yellow LED indicates the power on/off. After the power on, the yellow
LED will light on.

On the RJ45 connector, while the network is in linking, the yellow LED
turns on. During data transmitting or receiving, the green LED will flicker.
The flicker rate depends on the activity load.
