Logic Control
PS Inhibit When supply is inserted into the system the pin is
pulled LOW and power supply is ON after all other pins
are seated
PS_Status I2C 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.
AC_Pfail
I2C port P7. P7 is high except when the power supply
turns the main outputs, not +3.3VSB, 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.
Fan_Fault The PSU will provides an open collector Tach 1 output.
Tach_1
This signal is generated from the fan. The signal
should generate 2 pulses per revolution. The logic in
the system will be operating at 3.3V.
