The failing component is the system processor backplane.
Use the following table to determine which FRU to replace.
Note: To simplify this information, secondary units on the 9406-MMA and the 9117-MMA servers are numbered 1 through 3 with secondary unit 1 being nearest to the primary unit and secondary unit 3 being furthest.
| FRU name (replace in order, one at a time) | Location |
| For each unit, starting with the primary unit and then the secondary units: | |
Primary unit, system processor backplane. |
Un-P2 |
Secondary unit 1, system processor backplane (node backplane) |
Un-P2 | Secondary unit 2, system processor backplane (node backplane) |
Un-P2 | Secondary unit 3, system processor backplane (node backplane) |
Un-P2 |
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 | |
