SCSI Troubleshooting Checklist

The AHA-2740 Series has been extensively tested for compatibil-
ity with popular SCSI peripheral devices across various operating
systems. Most problems that might occur during 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 in Chapter 1, Introduction.
If a problem occurs during installation, check these items first:
1 Be sure all SCSI peripheral devices are connected to power.
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.
2 Be sure all cables are properly connected. Check both power
and SCSI interface cables. See Installation in Chapter 2.
3 Be sure the SCSI devices and host adapter on each SCSI bus
are each set to different SCSI IDs. See SCSI ID Setting in
Chapter 2.
4 Check SCSI bus termination. The ends of the bus must be
terminated. See Termination on the SCSI Bus in Chapter 2.
5 If you have installed more than one SCSI host adapter make
sure that each host adapter is set to a separate BIOS address,
or disable the BIOS on all but one of the host adapters. See
Configure the Host Adapter Parameters in Chapter 3.
If your problem is still not resolved, continue with the next
section.
