Ethernet controller
problem FRU/actions
The Ethernet controller
stopped working when
another adapter was
added to the server. Check the following:
v
Make sure that the cable is connected to the Ethernet controller.
v Make sure that your 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 your 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 latest information available concerning these messages will be made
available at the IBM Support Web site at http://www.ibm.com/pc/support.
