3. Are all of the adapters in the system missing or failed?
If Then
Yes: Perform the following actions, one at a time until the problem is resolved:
1. Ensure that the PCIe risers are fully seated in the system.
2. Replace system processor CPU 1.
3. Replace the system backplane.
Note:
v If your system is an 8001-12C or 8005-12N, go to "8001-12C or 8005-12N locations" on
v If your system is an 8001-22C or 8005-22N, go to "8001-22C or 8005-22N locations" on
No: Go to "Collecting diagnostic data" on page 71. Then, go to "Contacting IBM service and
support" on page 71.
