   LED1        Yellow      Blinking        Data is being transmitted

   LED1        Yellow         On         Data is not being transmitted

   LED2         Red        Blinking          Data is being received

   LED3        Green          On       Twisted pair network connection is
                                                      good

   LED3        Green         Off       Twisted pair network connection is

   LED4         Red           On         Twisted pair receive wires are
                                           reversed and corrected for

   LED4         Red          Off                Normal operation

  Note:If the link integrity test is disabled, LED3 will remain off.
