     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.
