The failing component is the RIO/HSL I/O bridge on the IPL path.
Use the following table to determine the part number for the field replaceable unit (FRU):
| CCIN or FFC | Type and model | Part number | Description | Location code |
| 8204-E8A | 10N9369 | System backplane | Un-P1 | |
| 9406-MMA, 9117-MMA | 42R7352 | For each unit, starting with the primary unit and then the secondary units, replace the I/O backplane | Un-P1 |
This ends the procedure.
