adapter or the PCI-X slot. Isolate the problem by swapping an identical adapter into the slot and
retrying. If you determine that you have failing hardware, call your service representative.
Note: After isolating the problem, be sure to swap the adapters back to their original slots.

Verifying jumpers on PCI-X adapter options
