LED status
5.1 Start-up
The LED located at the front of the router indicates the status of the router. At start-up, the
LED will alternate between red (R) and green (G) every 500ms for about two seconds. After
the start-up sequence the LED will indicate the Alarm state of the router.
There are two LEDs located at the Ethernet bus. At start-up the boot loader is searching for
update commands on the serial port for about two seconds. During this sequence both
Ethernet LEDs will be blinking. After the start-up sequence the LEDs will indicate the
Ethernet state.
5.2 Alarm states
The LED can either be red (R), green (G), yellow (Y) or have no light (N).
The LED state is here described with twenty letters, each representing 100ms, which totals
to an alarm sequence of two seconds. The X indicates that the LED keeps the color it has
the moment the alarm sequence begins (green, yellow or no light).
