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: Call your next level of support.This ends the procedure.17. Reinstall, in their original positions, the remaining I/O adapter 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.18. The problem is the multi-adapter bridge. Power off the system or partition.19. Determine which FRU contains the multi-adapter bridge which controls the IOP in the DSA byperforming 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 frametype that you recorded.b. Using the multi-adapter bridge number that you recorded, search for the multi-adapter bridgefunction number ″F″ in the card position table to determine the card position of the multi-adapterbridge’s FRU.20. 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 thisprocedure. Then, continue with the next step.v Yes: Call your next level of support.This ends the procedure.21. Exchange the card multi-adapter bridge’s FRU at the card position that you determined for it. Todetermine the remove and replace procedure for the multi-adapter bridge’s FRU, locate the FRU’scard position in the FRU locations and failing items table for the frame type that you recorded. FRUlocations and failing items tables are in Locations and addresses.22. Install the original IOP in its original position.23. Install all of the other IOPs and IOAs in to their original positions. Do not install the IOAs that youwere instructed to remove in step 5 (See page 93).24. Power on the system or partition.Does the SRC or failure that sent you to this procedure occur?v No: Install all of the IOAs that you removed in step 5 (See page 93). Be sure to install them in theiroriginal positions. Then, continue with the next step.v Yes: Call your next level of support.This ends the procedure.25. Power on the system or partition.Does the SRC or failure that sent you to this procedure occur?v No: This ends the procedure.v Yes: Call your next level of support.This ends the procedure.Bus PIP MAB-02: For use by authorized service providers.94 iSeries: iSeries Server 270, 800, 810, 820, 825, 830, 840, 870, 890, SB2, and SB3 Hardware Problem Analysis and Isolation
