Logic Control
Remote ON/OFF (PSON#)
The PSON# signal is required to remotely turn on/off the power supply. PSON# is an active low signal that turns on the +12VDC power rail.
When this signal is not pulled low by the system, or left open, the +12VDC output turns off. The 3.30Vsb output remains on. This signal is
pulled to a stanby voltage by a pull-up resistor internal to the power supply. The power supply fan(s) shall operate at the lowest speed
Signal Type
PSON# = Low
PSON# = Open
Accepts an open collector/drain input from the system. Pulled-up to the
3.30Vsb located in the power supply

Table 1 PSON# Signal Characteristics
Power Good (PWOK#)
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 an 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 +12VDC output is in current limit or the 3.30VSB output is below the regulation limit.
Signal Type:
Open collector/drain output from power supply. Pull-up to 3.30Vsb external to
the power supply

Table 2 PWOK# Signal Characteristics
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 3.3 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 indiciate a loss of AC input to the power supply.
