Ethernet controller troubleshooting chart
Use the following troubleshooting chart to find solutions to 10/100/1000 Mbps
Ethernet controller problems that have definite symptoms.
Ethernet controller
problem
FRU/actions
The computer stopped
running when loading
device drivers.
The PCI BIOS interrupt settings are incorrect.
v
Determine whether the interrupt (IRQ) setting assigned to the Ethernet controller is also
assigned to another device in the Configuration/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. For example, for NetWare
Versions 3 and 4, it is recommended that disk controllers not share interrupts with LAN
controllers.
v Make sure that you are using the most recent device driver available from the World
Wide Web.
v Reseat or replace the adapter.
Ethernet link status LED
does not work.
v Make sure that the hub is turned on.
v
Check all connections at the Ethernet controller and the hub.
v Use another port on the hub.
v
If the hub does not support auto-negotiation, manually configure the Ethernet controller
to match the hub.
v
If you manually configured the duplex mode, make sure that you also manually configure
the speed.
v Reseat or replace the adapter.
Data is incorrect or
sporadic.
v Make sure that you are using Category 5 or higher cabling when operating the computer
at 100 Mbps or at 1000 Mbps.
v Make sure that the cables do not run close to noise-inducing sources such as
fluorescent lights.
The Ethernet controller
stopped working when
another adapter was
added to the computer.
v
Make sure that the cable is connected to the Ethernet controller.
v Make sure that the PCI system BIOS code is current.
v
Reseat the adapter.
v Determine whether the interrupt (IRQ) setting assigned to the Ethernet adapter is also
assigned to another device in the computer. Use the Configuration/Setup Utility program
to determine if this is the case.
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.
v Reseat or replace the adapter.
The Ethernet controller
stopped working without
apparent cause.
v Try a different connector on the hub.
v
Reinstall the device drivers. See the operating-system documentation.
v Reseat or replace the adapter.
