2.4. Supplying power

When using the PB1176JZF-S as a standalone development system, you must connect the supplied brick power supply to power socket J44 or an external bench power supply to the screw-terminal connector J46. See Figure 2.3.

Note

If you are using the supplied brick power supply connected to J44, the Standby/power pushbutton S8 toggles the power on and off.

If you are using an external power supply connected to J46, or you are powering the board from the PCI backplane, the Standby/power switch is not used. You control the power by shutting down the external power source.

Caution

You can use only one power source for the system. Use only the PCI connector, J46, or J44. Do not, for example, use the PCI connector and J46 at the same time.
