Ethernet controller troubleshooting chart
You can use the following troubleshooting chart to find solutions to 10/100 Mbps
Ethernet controller problems that have definite symptoms.
Ethernet controller
problem
Suggested action
The server stops running
when loading device drivers. The PCI BIOS interrupt settings are incorrect.
Check the following:
• Determine if the interrupt (IRQ) setting assigned to the Ethernet controller is also
assigned to another device in the BIOS Setup Utility program.
Although interrupt sharing is allowed for PCI devices, some devices do not function
well when they share an interrupt with a dissimilar PCI device. Try changing the
IRQ assigned to the Ethernet controller or the other device.
• Make sure that you are using the most recent device driver available from the World
Wide Web.
• Run the network diagnostic program.
If the problem remains, call for service.
Data is incorrect or sporadic. Check the following:
• Make sure that you are using Category 5 cabling when operating the server at 100
Mbps.
• Make sure that the cables do not run close to noise-inducing sources like
fluorescent lights.
The Ethernet controller
stopped working when
another adapter was added
to the server. Check the following:
• Make sure that the cable is connected to the Ethernet controller.
• Make sure that your PCI system BIOS is current.
• Reseat the adapter.
• Determine if the interrupt (IRQ) setting assigned to the Ethernet adapter is also
assigned to another device in the BIOS Setup Utility program.
Although interrupt sharing is allowed for PCI devices, some devices do not function
well when they share an interrupt with a dissimilar PCI device. Try changing the
IRQ assigned to the Ethernet adapter or the other device.
If the problem remains, call for service.
The Ethernet controller
stopped working without
apparent cause. Check the following:
• Run diagnostics for the Ethernet controller.
• Try a different connector on the hub.
• Reinstall the device drivers. Refer to your operating-system documentation and to
the ServerGuide information.
If the problem remains, call for service.
