When the unit is removed from the system the fast shut down signal quickly turns OFF main outputs and discharges output capacitors. This signal is the shortest gold finger pin on the signal connector to allow for last make, first break configuration. PSOK (S6) Combined indicator of AC input and main 12 V DC output. This is a three level signal to indicate different stages as follows: AC not OK and DC not OK Signal status shall be LOW (< 0.6 V) AC OK and DC not OK Signal status shall be LOW (< 0.6 V) AC OK and DC OK Signal status shall be HIGH (> 3.0 V) AC not OK and DC OK Signal status shall be Middle Level (Between 2 V and 2.5 V) DC OK threshold is defined as when the 12 V output is greater than 11.5 V. DC not OK threshold is defined as when the 12 V output is less than 11.4 V & greater than 11.3 V. I-Mon (S7) Provides both the load sharing function (as a feedback for output regulation droop function) and 12 V output current information. PS INTERRUPT (S4) The signal behavior in response to certain operating condition changes in the power supply as defined in the Firmware Specification section. This signal shall be pulled up to maximum 5 V logic level external to the PS. PS ON (S8) Required to remotely turn on/off the power supply. PSON is an active low signal that turns on the main 12 V DC output. When this signal is not pulled low by the system, or left open, the 12 V output is turned off. This signal is pulled to a standby voltage by a pull-up resistor internal to the power supply. Refer to On/Off Timing for timing dia- gram in TRN. When in off or standby condition, the main 12 V DC output will be less than 50 mV with respect to output return.
