2.8. Supplying power

If the baseboard is not inserted into a PCI enclosure, you must connect the supplied 12VDC brick power supply to power socket J28 or an external bench power supply to the screw-terminal connector J27. See Figure 2.11.

Figure 2.11. Power connectors

Power connectors


If you are using the supplied brick power supply connected to J28, the Standby/power push button toggles the power on and off.

If you are using an external power supply connected to J27, or you are powering the board from the PCI backplane, the Standby/power switch is not used and power is controlled by shutting down the external power source.


You can use only one power source for the system. Use only one of the PCI connector, J27, or J28.

Do not, for example, use the PCI connector and J27 at the same time.
