v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved.
v See Chapter 4, "Parts listing," on page 109 to determine which components are customer replaceable units (CRU) and

1. Make sure that the component firmware is at the
latest level. The installed firmware level is shown
in the diagnostic event log in the Firmware/VPD
section for this component. For more
information, see "Firmware updates" on page
213.
2. Run the test again.
3. Check the interrupt assignments in the PCI
Hardware section of the DSA event log. If the
Ethernet device is sharing interrupts, if possible,
use the Setup utility see "Using the Setup utility"
on page 214) to assign a unique interrupt to the
device.
4. Replace the component that is causing the error.
If the error is caused by an adapter, replace the
adapter. Check the PCI Information and Network
Settings information in the DSA event log to
determine the physical location of the failing
component.
5. If the failure remains, go to the IBM Web site for
more troubleshooting information at
