A diagnostic function detects a connection problem between a processor chip and a GX chip. If replacing the FRUs previously listed in the FRU list does not fix the problem, perform the following:
| System: | Action: |
|---|---|
| 8203-E4A, 9407-M15, and 9408-M25 | Replace the system backplane (Un-P1). Refer to System FRU locations for information on locating the system backplane. |
| 8204-E8A and 9409-M50 | Replace the system backplane (Un-P1). Refer to System FRU locations for information on locating the system backplane. |
| 8234-EMA, 9117-MMA, and 9406-MMA | Replace the mid-plane backplane (Un-P1). Refer to System FRU locations for information on locating the regulator distribution backplane. |
| 9125-F2A | Replace the mid-plane backplane (Un-P1). Refer to System FRU locations for information on locating the regulator distribution backplane. |
| 9119-FHA | Replace the processor book (Un-Pm, where m = 2-9) for the failing FRU. |
