Monitoring LEDs

The status of the WR-ZEN device can be quickly verified using the 3 visible LEDs
in the front-panel. The tables below detail the behavior of each LED depending
on the status of the WR-ZEN.
The blinking behavior of the front panel LEDs is represented by the "Visual"
column in the following tables using a sequence of three consecutive instants.

General Status

This LED is mainly used to inform the state of the system itself (Daemons loaded,
Fans, power-supply, Temperature, CPU load, Available space, etc.).
This led is also used to identify the various stages and modes of the booting pro-
cedure.
