4.1.2 Reference Design Start-Up

Use the following steps to start the reference design:

  1. Connect a personal computer (PC) to micro USB connector J8 for terminal output, the D34 LED lights up
  2. Start terminal software with 115200 8N1 configuration
  3. Connect either a 24-V minimum, 500-mA power supply to J14, or connect a PoDL PSE to J7 or J6
  4. When powered from aux connector J4, the following LEDs light up: D15, D16, D9, D23, D17, D34, and D23
  5. When powered from PoDL the following LEDs light up: D14, D16, D9, D23, D17, D34, and D23
  6. More LEDs can light up, depending on the software that is running and on the Ethernet link state. For further details and the software-controllable LEDs, refer to the schematic.
