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 +3.3 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.
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 3.3 V.
