The backplane might be failing.
The failing component is the system backplane or I/O backplane.
Note: After you have replaced a system backplane or I/O backplane, make sure to set the enclosure
serial number before powering up, otherwise the machine will not perform an IPL. For more
information, see Setting the system enclosure type.
Complete the following steps:
- Is the system reference code (SRC) 11002634, and is the system an 8248-L4T, 8408-E8D, 8412-EAD, 9109-RMD, 9117-MMB,
9117-MMC, 9117-MMD, 9179-MHB, 9179-MHC, or 9179-MHD?
- No: Continue with the next step.
- Yes: Replace the system processor assembly at location Un-P3. If the server is a multiple-drawer server, use the last byte of word 2 of the SRC to identify the drawer in which the failing item is located. This ends the procedure.
- Is the server a multiple-drawer server, and is the SRC B1xxxxxx?
- No: Continue with the next step.
- Yes: Use the last byte in word 3 of the primary SRC to determine which
backplane to replace:
- If the last byte is a 10, replace the primary unit I/O backplane.
- If the last byte is a 20, replace the secondary unit 1 I/O backplane.
Note: If you don't have access to word 3 of the primary SRC, you can also determine which backplane to replace by using either of the following methods:- If you have access to the Advanced System Management Interface (ASMI), log on and display the
details of the service processor error log. Using the Platform Event Log id (shown in the first
table of each detail of the log), look at the first byte.
- If the first byte is a 50, replace the primary unit I/O backplane.
- If the first byte is a 51, replace the secondary unit 1 I/O backplane.
- If you have access to a management console, log in as PE user.
Display the event details for the corresponding service processor system. Look at the field Platform
log ID, which contains a decimal value that you need to convert to a hexadecimal value.
- If the first byte is a 50, replace the primary unit I/O backplane.
- If the first byte is a 51, replace the secondary unit 1 I/O backplane.
Continue with the next step.
- 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 |
| 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, 8205-E6D, 8231-E2B, 8231-E1C, 8231-E1D, 8231-E2C, 8231-E2D, 8268-E1D | See System parts. | System backplane Note: If the SRC reported is
11002611, go to PWR1918 to
complete the service action.

If you need additional information for failing part numbers, location codes, or removal and replacement procedures, see Part locations and location codes. Select your machine type and model number to find additional location codes, part numbers, or replacement procedures for your system.
This ends the procedure.
