SCSI Troubleshooting Checklist
TheAMM -1570/1572 host adapters have been tested for compatibil-
ity with popular SCSI devices. Most problems that might occur dur-
ing installation can be traced to errors in preparing devices on the
SCSI bus.
The following suggestions should help you to solve any problems
that you may encounter. If you need additional help in getting the
host adapter running properly, information on contacting Adaptec
Technical Support is included on page ii.
If a problem occurs during installation, check these items first:
■Be sure all cables are properly connected. Check both po wer
and SCSI interface cables. See D etailed Installation on page 3-5.
Connect internal peripherals to your computer's power sup-
ply; plug external peripheral power cables into a grounded
line power outlet. Follow the instructions in the hardware
documentation.
■Be sure the host adapter is firmly seated and secured in the
expansion slot it is installed in.
■Check SCSI bus termination. The devices at the ends of the bus
must be terminated. See Termination on the SCSI Bus on page
2-3.
■Be sure the SCSI devices and host adapter are each set to a
unique SCSI ID (0-7). SeeSCSI IDs on the SCSI Bus on page 2-7.
■If you have installed more than one SCSI host adapter make
sure that only one host adapter BIOS is enabled at a time.
If your problem is still not resolved, continue with the next section.
