2-26 Installing the LSI21040
2.4 Troubleshooting
Check these hardware items if problems arise:
•
Cabling – Use an unshielded 68 conductor Ultra SCSI TPE ribbon
cable and a 50-pin ribbon cable for internal connections. Ensure the
pin-1 orientation is correct for internal cables. Use a 68-pin high
density SCSI cable for external connections.
•
SCSI Devices – Set each SCSI device and the host adapter to a
separate SCSI ID 0 through 15. You must not have any duplication
of SCSI IDs on a SCSI bus. The default SCSI ID for the host adapter
is SCSI ID 7.
•
Termination – Automatic termination is enabled when the LSI21040
is connected to the end of the bus. For internal and/or external bus
connections, terminate the last internal and/or external device on the
SCSI bus.
