BRDGSET

The problem might 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. This symbolic FRU only appears in the serviceable event user interface when the Licensed Internal Code could not determine which PCI bridge set has the problem.

1. Are you working from a serviceable event user interface of an operating system, service processor, or the HMC that is giving you a card position or list of card positions for this FRU?
   • Yes: Go to step 5. Note: 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.
   • No: Complete the following steps:
     1. Determine the location of the cards in the group using the DSA. Record the DSA (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 card(s).
2. Did isolation procedure MABIP53 identify a single card location?
   • Yes: This is the location of the failing item. Go to step 5.
   • No: Complete the following (see the table below):
     1. Remove all of the adapter and/or 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. Then continue with the next step.
3. Did the problem reappear?
   • Yes: The last card that you replaced before the problem reappeared is the failing item. This ends the procedure.
   • No: Continue with the next step.
4. Did isolation procedure MABIP53 identify a FRU with embedded adapters?
   • Yes: The problem is in the FRU with the embedded adapter. Continue with the next step and replace that FRU using the following table.
   • 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 following table to locate and replace the failing item(s).
