Pin Assignments for the DC Power Connectors The power-supply output voltages can be measured at the back (wire side) of the connectors without disconnecting them. Figures 1-6 through 1-8 show the wire side of the connectors. open +5 VDC (red) common (black) +5 VDC (red) common (black) +5 VDC (red) common (black) PSON# 1 (grey) TFSC2 (brown) +5 VDC (red) 11 12 13 14 15 16 17 18 19 20 P1 1 2 3 4 5 6 7 8 9 10 +5 VDC (red) common (black) common (black) +5 VDC (red) common (black) PWRGOOD 3 (orange) common (black) -12 VDC (blue) +12 VDC (yellow) +5 VFP (purple) 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 to indicate that all power-supply output voltages are within the ranges specified in Table 1-1.
