 === Use of the Multi-Color RGB LED
 
-FIXME: describe how it is used.
+The led near the USB port is used to indicate general device status.
 
+A blinking blue led indicates that the device is in bootloader mode.
+
+A slow breathing indicates that at least one of the two port is
+active, communicating over USB. The color of the led then indicates
+the E1 link status. If all links are without issues, it will be
+green, but if at least one of the enabled port has an issue,
+it will show up as red.
