The hardware, firmware, microcode, or device driver of an adapter or card slot detected an error.

The failing component is the adapter in the location specified in the SRC.

1. Are you working from the serviceable event view and is there a card location listed with this FRU?
   • Yes: Use Table 1 to replace the adapter identified by this location code. This ends the procedure.
   • No: Determine the location of the adapter by working with the customer or your next level of support. If you cannot determine the location of the failing adapter by using SRC or resource information or the device tree, then determine the adapter type from the SRC, SRC description, failing resources, or error message you are working with. Make a list of all the adapter locations of that type assigned to the partition. Continue with the next step.

2. Have you identified a single FRU location?
   • Yes: Use Table 1 to replace the FRU you have identified. This ends the procedure.
   • No: Continue with the next step.

3. Using the location codes you have identified, determine which system unit and expansion units have PCI adapters of this type assigned to the partition you are working with. Starting with the expansion units first, remove all of the PCI adapters of this type from one of the units (use Table 1 to guide you to the correct locations information).
   Attention:
   • Remove the PCI adapters from the system unit only after you have tried all of the expansion units first.
   • Do not remove any FRUs with embedded adapters, only FRUs in PCI card slots.
   Continue with the next step.

4. Reinstall one of the adapters and power on the unit. Continue with the next step.

5. Does the problem reoccur?
   • Yes: The adapter you just reinstalled is the failing item and needs to be replaced (use Table 1 to guide you to the correct locations information). This ends the procedure.
   • No: Continue with the next step.

6. Have you reinstalled all of the adapters on the unit you're currently working with?
   • Yes: Continue with the next step.
   • No: Return to step 4 and reinstall the next adapter on this unit.

7. Are there any units (including the system unit) on which you have not yet removed and reinstalled the PCI adapters?
   • No: Continue with the next step.
   • Yes: Return to step 3 and work with another unit.

8. Go to "Card Positions" in the service guide for the unit on which you are working to determine if system unit or any of the expansion units has an embedded adapter of the type you are working with. Is there such an embedded adapter?
   • No: The problem might be intermittent. Contact your next level of support. This ends the procedure.
   • Yes: The FRU with the embedded adapter is the failing item and needs to be replaced. Use Table 1 to exchange the FRU at the location specified in the card position table. Repeat this step for each expansion unit with an embedded adapter assigned to the partition, and then for the system unit. This ends the procedure.
