Bus SRN to FRU Reference Table
This table is used to locate defective FRUs within the system board PCI and ISA
buses, and indicates which devices should be tested for each SRN. For this
procedure, if possible, diagnostics are run on the riser card 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 riser card 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.
