remove and replace procedures for the IOPs and IOAs, locate the card positions in the FRU locations
and failing items table for the frame type you recorded. FRU locations and failing items tables are in
Locations and addresses.
5. Power on the system or partition.
Does the SRC or failure that sent you to this procedure occur?
v No: Continue with the next step.
v Yes: The problem is the multi-adapter bridge. Continue with step 12 (See page 98).
6. Starting at the empty card position with the lowest multi-adapter bridge function number from the
form, reinstall, in their original positions, one of the IOPs and all the IOAs between it and the next
IOP.
7. Power on the system or partition. Does the SRC or failure that sent you to this procedure occur?
v Yes: The I/O processor card that you just installed is the failing FRU. Continue with the next step.
v No: Power off the system or partition. Repeat step 6 (See page 98) 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.
8. Power off the system or partition.
9. Exchange the I/O processor card you last installed. Be sure to install the new I/O processor card in
the same position.
10. Power on the system or partition.
Does the SRC or failure that sent you to this procedure occur?
v No: Power off the system or partition. Then, continue with the next step.
v Yes: Remove the IOP that you just installed and replace the original IOP in its original position.
Perform "Bus PIP IOP-03" on page 92.
This ends the procedure.
11. 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?
v Yes: Call your next level of support.
This ends the procedure.
v No: Does a different SRC occur?
– Yes: Follow the service procedures for the new SRC. Start with "Starting point for all problems"
on page 2.
This ends the procedure.
– No: Perform "Bus PIP verify - RA" on page 101.
This ends the procedure.
12. Power off the system or partition.
13. 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 positions"
on page 65 (located in the Bus PIP Overview topic) 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.
14. Is the multi-adapter bridge's FRU a FRU that you have already exchanged?
v No: Remove the IOP that you exchanged. You will be reinstalling the original IOP later in this
procedure. Then, continue with the next step.
