.1 Status LED Output & Remote On/ Off Control
For an application which places the system inside a cabinet, it’s useful to have an
external system status LED indicators. The system provides a 2x6, 2.0mm pitch pin
header to output system status such as power, HDD, watchdog timer, and control
system on/ off remotely.
The status LED output has a built-in series-resistor and provides 10mA current to
directly drive the external LED indicators. System on/ off control is also provided so
you can use an external non-latched switch to turn on/ off the system exactly the
same as the power button on the front panel. The following table describes the pin
definition of the status LED output.
