↓ Power off the system or partition. Repeat step 7 on page 318 for
another one of the I/O processor cards that you removed.
If you have reconnected all of the IOPs and the SRC or failure that
sent you to this procedure does not occur, the problem is intermittent.
This ends the procedure.
9. The I/O processor card that you just installed is the failing FRU.
10. Power off the system or partition.
11. Exchange the I/O processor card you last installed. Be sure to install the new
I/O processor card in the same position.
12. Power on the system or partition.
Does the SRC or failure that sent you to this procedure occur?
No Yes
↓ Remove the IOP that you just installed and replace the original IOP in
it’s original position. Perform “BUS PIP IOP-03” on page 311.
This ends the procedure.
13. Power off the system or partition.
14. Reinstall, in their original positions, the remaining IOP and IOA cards that
you removed.
Does the SRC or failure that sent you to this procedure occur?
No Yes
↓ Call your next level of support.
This ends the procedure.
15. Does a different SRC occur?
Yes No
↓ Perform “BUS PIP VERIFY - RA” on page 323.
This ends the procedure.
16. Follow the service procedures for the new SRC. Start with “Starting Point for
All Problems” on page 4.
This ends the procedure.
17. The problem is the multi-adapter bridge. Power off the system or partition.
18. Determine which FRU contains the multi-adapter bridge which controls the
IOP in the DSA by performing the following:
a. Locate the card position table for the frame type that you recorded. Refer
to the “Card Position Tables” on page 282 to locate the card position table
for the frame type that you recorded.
b. Using the multi-adapter bridge number that you recorded, search for the
multi-adapter bridge function number ″F″ in the card position table to
determine the card position of the multi-adapter bridge’s FRU.
19. Is the multi-adapter bridge’s FRU a FRU that you have already exchanged?
No Yes
↓ Call you next level of support.
This ends the procedure.
20. Remove the IOP that you exchanged. You will be reinstalling the original IOP
later in this procedure.
