Base System
2.1.1 Status LEDs
There are three LEDs (green, yellow and red) located on the eDAQ
lite
front panel that
are important indicators of eDAQ lite status.
Initial State
When powering on, all three LEDs turn on indicating that the main processor is starting
the boot up process. However, the eDAQ
lite
displays different LED states than this on
abnormal conditions as defined by the following table.
NOTE
If all three LEDs stay on for more than about 10 seconds, the boot has failed at a very
early stage or the boot was interrupted in the serial loader (which should not happen
accidentally).
Possible States
After all three LEDs are on, the main processor boot up begins. The LED states that
can exist after the boot up starts are defined as follows.
