Ethernet controller
problem FRU/actions
The computer stops
running when loading
device drivers. The PCI BIOS interrupt settings are incorrect.
Check the following:
v Determine if 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. Check the following:
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. Check the following:
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 like fluorescent
lights.
The Ethernet controller
stopped working when
another adapter was
added to the computer. Check the following:
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 if the interrupt (IRQ) setting assigned to the Ethernet adapter is also assigned
to another device in the system. 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. Check the following:
v Try a different connector on the hub.
v Reinstall the device drivers. See the operating-system documentation and the
ServerGuide
™
information.
v Reseat or replace the adapter.
Ethernet controller messages
The integrated Ethernet controller might display messages from certain device
drivers. The information in this section might be helpful. The latest information
available concerning these messages will be made available at the IBM Support
Web site at http://www.ibm.com/pc/support.
Note: Although the term
″
adapter
″
is used in these messages, the messages might
also apply to the integrated Ethernet controller on the system board.
