    LED2            On                      Normal operation

    LED3         Blinking                Data is being received

    LED3            On           Data is not being received/Twisted pair
                                         network connection good

    LED3            Off          Twisted pair network connection broken

    LED4         Blinking               Data is being transmitted

    LED4            Off               Data is not being transmitted

  Note: The function of LED3 is dependent on the cable type selected.

  LED3 will indicate twisted pair network connection only when the cable
  type is twisted pair.
