100/10 Ethernet Adapter Troubleshooting

•  Make sure the cable is installed correctly.

   The network cable must be securely attached at all connections. If the cable is attached but the problem persits, try a different cable.

   If you see the Ethernet adapter to operate at 100 Mbps you must use Category 5 cabling. Refer to  the Hardware Specifications and Cabling Information section in the help file for a list  of recommended cables and information on how to install cabling.

   If you directly connect two workstations (no hub), use a crossover cable. Refer to  the Hardware Specifications and Cabling Information section in the help file.

•  Check the LEDs on the rear of the Ethernet adapter.

   The Ethernet adapter has three diagnostic LEDs beside the cable connector. These lights help indicate whether a problem  exists with the connector, cable, or hub.

  •  The LNK LED illuminates when the adapter receives a LNK pulse from the hub. If the LED is OFF, there might  be a bad connection or cable, or a problem with the hub. The LNK LED is also OFF when you run the diagnostic tests in the  Setup program.
  •  The ACT LED illuminates when the adapter detects read or write activity on the network, even when there is no activity on the adapter.  If the ACT LED is not on, make sure that the hub and network are operating and that the correct drivers are loaded.
  •  The 100 LED illuminates when a 100 Mbps connection is established.

•  Make sure that you re using the correct drivers.
•  Check for operating system-specific causes for the problem.
•  Test the adapter.
