Led-Act
(Led-lnk/act)
O
4Leds mode: LED display for Activity status. This pin will be driven on with
10 Hz blinking frequency when either effective receiving or transmitting is
detected.
(3Led mode): LED display for link and activity status. This pin will be
driven on continually when a good Link test is detected. This pin will be
driven on with 10 Hz blinking frequency when either effective receiving or
transmitting is detected.
103
Led-10Lnk
(Led-fd/col)
O
4Leds mode: LED display for 10M b/s speed. This pin will be driven on
continually when the 10M b/s network operating speed is detected.
(3Leds mode): LED display for Full Duplex or Collision status. This pin will be
driven on continually when a full duplex configuration is detected. This pin
