BACKPLN
A backplane or a connection to the backplane might be failing.
Note: Before replacing any parts, verify the connections
to the backplane.
Complete the following steps:
- Were you sent here by a power reference code (1xxxxxxx)?
- No: Continue with the next step.
- Yes: Go to SYSBKPL. This ends the procedure.
- Determine the location of the device by performing the following
steps:
- Use the location information in the error log if it is available. If no location information for the device is available, use the location information for the I/O adapter instead.
- If no location information is available for either the device or the I/O adapter, find the address of the device or I/O adapter (see the System reference code format description). Use the address to find the location. See Part locations and location codes.
- Use the location code to determine in which unit the device, cable,
and the connected backplane are located. Any backplane connecting
the device or I/O adapter might be the cause of the problem. Use the
following table to determine the part number for the field replaceable
unit (FRU).
