Troubleshooting b. There might be a defective Ethernet connector or cable, or a problem with the hub. 3. Make sure that you are using the correct device drivers that come with your server. 4. Check for operating system-specific causes for the problem. 5. Test the Ethernet controller or adapter. How you test the Ethernet controller or adapter depends on which operating system you are using (see "Configuring the Ethernet Controller" on page 44). 10/100 Mbps Ethernet Controller Troubleshooting Chart You can use the following troubleshooting chart to find solutions to Ethernet controller problems that have definite symptoms. Controller Problems The Configuration/Setup Utility program reports the Ethernet controller interrupt Utility as 0 or 255. The Configuration/Setup Utility program reports No PCI Bus. The server stops running when loading device drivers. The diagnostics are completed successfully, but the connection fails. Action The PCI BIOS is not configuring the Ethernet controller or adapter correctly. The PCI BIOS interrupt settings are incorrect. Check for interrupt conflicts with ISA devices. If conflicts are found, reserve the ISA interrupts (see "ISA Legacy Resources" on page 40) so that the PCI BIOS will assign another non-conflicting PCI interrupt value. The Configuration/Setup Utility program has been run on another computer that does not have any PCI slots. Run the Configuration/Setup Utility program on your server so that the PCI BIOS will configure the Ethernet controller or adapter correctly. The PCI BIOS interrupt settings are incorrect. Check for interrupt conflicts with ISA devices. If conflicts are found, reserve the ISA interrupts (see "ISA Legacy Resources" on page 40) so that the PCI BIOS will assign another non-conflicting PCI interrupt value. 1. Make sure that the network cable is securely attached. 2. Make sure that you are using Category 5 cabling when operating the server at either 10 Mbps or 100 Mbps. 174 Netfinity 3500 User's Handbook
