The power-supply output voltages can be measured at the back (wire side) of
the connectors without disconnecting them. Figures 1-15 through 1-17 show
the wire side of the connectors.
1
Pin 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.
2
Pin 19 — Thermal fan-speed control (TFSC) is a power-supply input signal used to control
the power-supply fan speed.
3
Pin 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 1-4.
