LED Function Indicators
LED
Meaning
ACT/LNK
On
The adapter and switch are receiving power; the cable connection
between the switch and adapter is good.
ACT/LNK
Off
The adapter and switch are not receiving power or there is a driver
configuration problem.
If the LED is off:
• Make sure power is connected to the PC. If power is connected
and the LED is still off:
— Make sure the WOL cable is attached and power is applied to
the computer.
— Make sure the network cable is attached at both ends.
• Make sure you’ve loaded the network drivers.
• Check all connections at the adapter and the switch and make
sure both ends are connected.
• Try another port on the switch.
• Make sure the duplex mode setting on the adapter matches the
setting on the switch.
• Make sure you have the correct type of cable between the
adapter and the hub. 100BASE-TX requires two pairs. Some
hubs require a cross-over cable, while others require a straight-
through cable.
• Make sure you’ve loaded the correct network drivers.
ACT/LNK
Flashing
The adapter is sending or receiving network data. The frequency of
the flashes varies with the amount of network traffic.
If the ACT/LNK LED does not flash, the cause could be:
• The network may be idle. Try accessing a server.
• The adapter may not be transmitting or receiving data. Try
another adapter.
• Make sure you’re using two-pair cable for TX wiring.
