DS760SL Series Data Sheet
PSKILL
The +12 Vdc output only from the power supply shall be disabled if
the PSKILL input is high and V Standby will continue to be
provided, outputs may be enabled if this signal is low. The power
supply includes a pull up to disable all outputs if this signal is open.
PSKILL whall not be connectd during a hot insertion before all of
the other pins are connected.
STATUS INDICATIONS
See table below for Summary of Status signals, Ports and
Indicators. The condition column assumes 2 or more power
supplies present and ON and 5.0 Vsb shared for management
interface. On the “Fan Blocked” condition, the assumption is that
all outputs are within spec and not over temperature. This would
be considered a “warning” condition. On the “Standby” condition,
the system differentiates this state by knowing PS_ONL in
negated (requesting Standby).
AC INPUT PRESENT INDICATOR (ACOK^#)
The ACOK^# signal is used to indicate presence of AC input to the
power supply. This signal shall be connected to 5.0 Vsb through a
resistor on the host system side. A logic “High” level on this signal
shall indicate AC input to the power supply is present. A Logic
“Low” on this signal shall indicate a loss of AC input to the power
supply.
