1Pin 11 — PSON# should measure between +4 and +5 VDC except when the power button on the front panel is pressed, taking PSON# to its active-low state.

2Pin 19 — Thermal fan-speed control (TFSC) is a power-supply input signal used to control power-supply fan speed in special applications.

3Pin 5 — PWRGOOD should measure between +4 and +5 VDC when the power supply is on and operating to indicate that all power-supply output voltages are within ranges specified in Table 1-1.
