BSH (microprocessor board): After power up, or after a reset, the
green and yellow LEDs will both be lit while self diagnostics are in
progress (which will take about 10 seconds). If all diagnostics pass, the
yellow LED will extinguish and the green LED will remain lit. If a
failure is detected during diagnostics, the green LED will extinguish and
the yellow LED will remain lit.
If a failure occurs during normal operation, the green LED will
extinguish and the yellow LED will light.
