The SCSI I/O controller might be failing.
Use the following table to determine the part number for
the field replaceable unit (FRU).
| CCIN or FFC |

Generic SCSI I/O controllerNote: - If the failing FRU for this FFC is PCI(x), where x is the PCI
bus number, 0, 1, and so forth, see FFC 221.
- Use the location code to identify the failing FRU. If the failing
FRU is integrated on the system backplane, use FFC
221. If the failing FRU is not integrated on the system backplane,
replace the FRU identified by its description that is shown with the
location code for SCSI and SCSI-2 adapter. Choose the FFC for the
appropriate SCSI I/O controller.
- Check the SCSI controller fuse or PTC resistor before exchanging
the system board. See the SCSI-2 Single-Ended adapter PTC Failure
Isolation Procedure in the SCSI service hints.
- Check that the SCSI disable jumper is in the enabled position.
- Check the FRU part number of the installed external terminator.
The low density FRU part number is 51G7736. The high density FRU part
number is 51G7737.
