Connector Pin Assignments A-15
Power Supply Connectors
Table A-18 provides the pin assignments for the riser card power supply connector (J3J1).
The power supply connector differs from the standard NLX and ATX power supply
connectors. Pin 18 of the PowerMate NetPC power supply is used for thermal fan speed
control and not for -5V.
WARNING:
Do not use a standard NLX or
ATX power supply to operate the NetPC system,
as this will cause the fan circuit to fail.
The power supply supports remote power on/off. This means that the system board and
riser card can turn off the system power through software control. Pin 14 of the power
supply connector lets the system board recognize a power supply that supports this “soft-
off” feature.
