Ethernet Onboard/Adapter Troubleshooting (100/10 PCI)

The following troubleshooting information is for problems that might occur when the Ethernet controller is installed in the server.

Network Connection Problems

If the adapter cannot connect to the network, check the following:

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 persists, try a different cable.
If you set the Ethernet adapter to operate at 100 Mbps, you must use Category 5 cabling.
If you directly connect two workstations (without a hub), use a crossover cable.
Note: To determine wether a hub has an X port, check the port label.
If the label contains an X , the hub has an X port.
Check the LEDs on the rear of the Ethernet adapter (or operator information panel - Netfinity Servers).
The Ethernet adapter has three diagnostic LEDs beside the cable connecter. These lights help indicate whether a problem exists with the connecter, cable, or hub.
- The LNK (Ethernet Link status) LED illuminates when the adapter receives a LNK pulse from the hub.
  If the LED is OFF, there might be a bad connector 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 (Ethernet Transmit/Receive Activity) 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 (Ethernet Speed) LED illuminates when a 100 Mbps connection is established.
Make sure that you are using the correct device drivers (supplied with the server).
Check for operating system-specific causes for the problem.
Make sure that the device drivers on the client and server are using the same protocol.
Test the adapter.
Select Test adapter from the Main Menu on the Ethernet adapter Configuration and Drivers diskette. How you test the adapter depends on which operating system is being used. (see 'Ethernet Adapter Configuration (100/10 PCI)').
