5.1.2 Power-Up

There are five potential sources of power in this design:

• The primary power is through the Ethernet RJ45 (J8). The user must ensure that the switch or hub used is PoE PSE equipment.
• The design can be powered by using the external adapter input connector (11) through a 12-V DC power supply.
• The design can be powered from a 5-V DC power supply by removing the jumper on J4, placing jumper on J2 (POE3v3 and VCC3v3) and applying 5-V input to Pin-2 of J4.

NOTE

GND from the external power supply must be connected to TP11.

• The design can be powered from a 3.3-V DC power supply by removing the header (J9) and applying 3.3-V input to Pin-1 of J9.

NOTE

GND from the external power supply must be connected to TP5. In this configuration, the 5 V is not available on the BoosterPack headers.

• Placing shunt jumper J2 and J4 on XDS5V and XDS3V3, respectively, to power through USB port J14
