AT-2560FX 100 PCI Troubleshooting

If the AT-2560FX 100 PCI can’t connect to the network

❑ Make sure the cables are installed properly

The network cables must be securely attached at all connec-

tions. The transmit connector on one end must be connected

to the receive on the other and vice versa. If the cables are

attached properly but the problem persists, try swapping

out the cables.

❑ Check the LEDs on the adapter

The AT-2560FX 100 PCI has three diagnostic LEDs above

the cable connectors. These lights help indicate if there’s a

problem with the connector, cable, or hub.

The TX light is ON when the adapter sends data. The RX

light is ON when the adapter receives data; it flashes when

the cable is connected properly. The FD light is ON when

the adapter is operating in full-duplex mode.

❑ Make sure you’re using the correct drivers

You must use drivers designed for this adapter.

❑ Test the adapter

Test the adapter as described in this guide. Remember, how

you test the adapter depends on which operating system

you’re running.
