PWOK# (Power Good)
PWOK# is a power good signal and will be pulled LOW by the power supply to indicate that both the
outputs are above the regulation limits of the power supply. When any output voltage falls below
regulation limits or when AC power has been removed for a time sufficiently long so that power supply
operation is no longer guaranteed, PWOK will be de-asserted to a HIGH state. The start of the PWOK#
delay time shall be inhibited as long as the 48 V output is in current limit or the 5 Vsb output is below
the regulation limit.

Power Supply Present Indicator (PRESENT#)
The PRESENT# signal is primarily used to provide a mechanism by which the host system can sense the
number of power supplies physically present (operational or not). This pin is connected to ground in the
power supply.
AC INPUT Present Indicator (ACOK#)
The AC OK# signal is used to indicate presence of AC input to the power supply. This signal shall be
connected to 5 Vsb through a resistor on the host system side. A logic “Low” level on this signal shall
indicate AC input to the power supply is present. A Logic “High” on this signal shall indicate a loss of AC
input to the power supply.
