The multi-adapter bridge hardware is having a problem with one or more PCI cards or adapters in the PCI bridge set, but the exact card or adapter cannot be identified. 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 LIC could not determine which PCI bridge set has the problem.
