SYS LED (P300)
The SYS LED is a Duo-LED with the colors yellow and green. It provides
information on the current system status of the netRAPID 90.
A solid green SYS LED indicates that the firmware of the netRAPID H90 is
operational (Pin #39 RUN#). A yellow SYS LED indicates that the boot
loader is waiting for software or firmware. If the SYS LED is not lit, this
indicates missing power supply or defective hardware.
At boot-up, the signal lines RDY# and RUN# are also used for activating
alternative boot mode or console mode, see the description of
