During startup, the network engine automatically initiates a self-test to verify proper operation of the unit. Immediately after connecting supply power, the following LED lighting sequence occurs:

  • The HEARTBEAT LED flashes blue/purple when the network engine starts.
  • The FAULT LED is solid red for approximately 30 seconds, then turns off.
  • The USB-1 and USB-2 LEDs flash green when a supported device is connected to the respective USB port. The LEDs turn solid red when an unsupported device is connected. The LEDs are off if no device is connected.
