C port P6. When the power supply is on and running normal P6 is low. When the power supply is off, either due
to -PS_ON, PS_KILL, or a fault, then P6 is high.
I
2
C port P7. P7 is high except when the power supply turns the main outputs, not +3.3 Vsb, off due to an AC failure
(AC missing or too low for power supply operation). If the supply is turned off due to -PS_ON, PS_KILL, or a fault,
then P7 remains high.
The PSU will provides an open collector Tach 1 output.
This signal is generated from the fan. The signal should generate 2 pulses per revolution. The logic in the system
will be operating at 3.3 V.
