Auxcbl; Auxioa; Backpln - IBM iSeries Series Hardware Problem Analysis And Isolation

The Windows NT Server Application Processor device driver may be causing the problem. Refer to the
Windows server on iSeries page, which is located in the Networking topic in Information Center, or contact
your next level of support for assistance.

AUXCBL

Replace the SCSI cable that connects the auxiliary cache I/O adapter to the storage I/O adapter.
1. Find the location of the auxiliary cache I/O adapter:
a. Determine the address of the auxiliary cache I/O adapter. See System reference code (SRC)
address formats.
b. Determine the location of the auxiliary cache I/O adapter. See Part locations and listings for the
model you are working on.
2. Replace the SCSI cable that connects the auxiliary cache I/O adapter to the storage I/O adapter. See
Type, model, and part number list for cable part number information. This ends the procedure.
Note: In order to replace the SCSI cable concurrently, you must use concurrent maintenance to power
off the auxiliary cache I/O adapter. Replace the cable and then use concurrent maintenance to power
on the auxiliary cache I/O adapter. Do NOT replace the cable when both adapters are powered on.

AUXIOA

Replace the auxiliary I/O adapter. Use the location information in the Service Action Log, if it is available. If
the location information is not available, determine the address of the auxiliary cache I/O adapter. See
System reference code (SRC) address formats. Use the address to find the location (see Part locations
and listings).

BACKPLN

For use by authorized service providers.
A backplane or a connection to the backplane may be failing.
Before replacing any parts, the connections to the backplane should be verified. The following steps
identify which backplane may be failing.
1. Were you sent here by a power SRC (1xxx xxxx)?
v No: Continue with the next step.
v Yes: Go to sybmolic FRU "SYSBKPL" on page 464.
2. Determine the location of the device by doing the following:
v Use the location information in the Service Action Log if it is available.
v If no location information for the device is available, use the location information for the I/O adapter
instead.
v 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 SRC address formats. Use the address to find the location. See
Locations and addresses.
3. Is the device or I/O adapter located in a migrated tower?
v No: Use Power and signal cables to locate the device, cable, and backplane. Any backplane
connecting the device or I/O Adapter may be the cause of the problem. For backplane part numbers
and remove and replace procedures, see Locations and addresses.
This ends the procedure.
v Yes: Go to symbolic FRU BACKPLN in the Migrated Expansion Tower Problem Analysis, Repair and
Parts manual on the V5R1 Supplemental Manuals web site
This ends the procedure.
