Bus SRN to FRU Reference Table
This table is used to locate defective FRUs within the I/O board PCI and ISA buses.
The table indicates which devices should be tested for each SRN. For this
procedure, if possible, diagnostics are run on the I/O board bus devices with all
adapters removed from the failing bus. If a failure is detected on this system with all
adapters removed from the failing bus, the I/O board is the isolated FRU. If a failure
is not detected, the adapters are added back one at a time, to their original slot
location, and the configuration is tested until a failure is detected. The failure is then
isolated to the failing FRU.
If a failure has not been detected and all the FRUs have been tested call your
technical service support person for assistance.
