BRDGST2

The multiadapter bridge hardware is having a problem with one or more PCI cards or adapters in the second PCI bridge set in the enclosure, but the exact card or adapter cannot be identified. The problem can be with a card, a card slot, or an embedded adapter. The PCI bridge set is indicated by the direct select address (DSA) in word 7 of the reference code.

1. Are you working from a serviceable event user interface of an operating system, service processor, or management console that is giving you a card position or list of card positions for this FRU?
   • Yes: The positions given are the locations of the failing components. When there is a list of locations in this FRU's location code, the card locations will be separated by commas. A range of card positions will show the starting card position, a colon, and the ending card position. Go to step 5.
   • No: Complete the following steps:
     1. Determine the location of the cards in the group using the DSA. Record the DSA, which is word 7 of the reference code, from the user interface you are using.
     2. Locate the cards specified in the DSA by performing isolation procedure MABIP53. Return here and continue with the next step after locating the cards.
2. Were you able to identify a single card position by performing MABIP53?
   • Yes: This is the location of the failing item. Go to step 5.
   • No: Continue with the next step.
3. Complete the following, referring to the remove and replace procedures for each FRU location you determined:
   1. Remove all of the adapter and IOP cards in the locations that are identified in the given range of card slots. Do not remove any FRUs with embedded adapters, only FRUs in PCI card slots.
   2. Replace each card one at a time.
      Note: For IBM® i adapters controlled by IOPs, replace the IOP before any of the adapters.
      Power on the unit after you replace each card until either the problem reappears or you have replaced each card.
   3. Did the problem reappear?
      • Yes: The last card that you replaced before the problem appeared again is the failing item. This ends the procedure.
      • No: Continue with the next step.
4. Did you identify a FRU with embedded adapters when performing isolation procedure MABIP53?
   • Yes: The problem is in the FRU with the embedded adapter. Continue with the next step and replace that FRU.
   • No: The problem might be intermittent. Contact your next level of support. This ends the procedure.
5. For each unit, starting with the primary unit and then the secondary units, use the links in the table below to locate and replace the failing items.

   CCIN or FFC	Type and model	Part number	Description	Location code
   	8248-L4T, 8408-E8D, 8412-EAD, 9109-RMD, 9117-MMB, 9117-MMC, 9117-MMD, 9179-MHB, 9179-MHC, 9179-MHD	See System parts.	I/O backplane, PCI bridge set 2	Un-P2, Un-P2-C1, Un-P2-C2, Un-P2-C3, Un-P2-C4
   	5796, 7314-G30	See System parts.	I/O backplane, PCI bridge set 2	Un-P1, Un-P1-C4, Un-P1-C5, Un-P1-C6

   If you need additional information for failing part numbers, location codes, or removal and replacement procedures, see Part locations and location codes. Select your machine type and model number to find additional location codes, part numbers, or replacement procedures for your system.

This ends the procedure.
