Bus SRN to FRU Reference TableThis table is used to locate defective FRUs within the system board PCI and ISA buses.The table indicates which devices should be tested for each SRN. For this procedure, ifpossible, diagnostics are run on the system board bus devices with all adaptersremoved from the failing bus. If a failure is detected on this system with all adaptersremoved from the failing bus, the system board is the isolated FRU. If a failure is notdetected, the adapters are added back one at a time, to their original slot location, andthe configuration is tested until a failure is detected. The failure is then isolated to thefailing FRU.If a failure has not been detected and all the FRUs have been tested, call technicalservice support for assistance.Table 5.
