Bus Srn To Fru Reference Table - IBM RS/6000 44P 270 Service Manual

Bus SRN to FRU Reference Table

This table is used to locate defective FRUs within the I/O board's 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 technical
service support for assistance.
