Power Good Signal
The jumper JP4 controls the origin of the power good signal,
either from the power supply or from the board circuit. The factory
setting is from the board circuit. AT power supplies have a power
good signal output. However, other power supplies may not and the
alternative setting of JP4 allows for these types of power supplies to
be used with the NEATsx. Short 1-2 for power good signal from the
power supply; 2-3 (default) for on board power good signal. The fig­
ure below illustrates the appropriate settings.
