During startup, the SBH automatically initiates a self test to verify correct operation. Immediately after you connect the supply power, the following LED lighting sequence occurs:
- The POWER LED starts on purple and then turns blue and stays on.
- The FAULT LED flashes for approximately 30 seconds, then turns off and the RUN LED turns solid when the SBH is fully functional.
- The Wi-Fi LEDs remain off until you connect the Wi-Fi dongle. When you connect the Wi-Fi dongle, the corresponding USB LED turns on and the Wi-Fi AP LED flickers, which indicates that the SBH is waiting for a device.
