SCSI Troubleshooting Checklist

The AVA-2820/2822/2825 host adapters have been tested for com-
patibility with popular SCSI devices. 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
you may encounter. If you need more help in getting the host
adapter running properly, see Adaptec Technical Support and Services
on page ii.
If a problem occurs during installation, check the following items
first:
All cables are properly connected. Check power, SCSI, floppy,
and standard IDE or EIDE interface cables. See Connecting SCSI
Devices on page 2-10, Connecting Floppy Drives (AV A-2822/2825
Only) on page 2-18, and Connecting Standard IDE or EIDE
Drives (AV A-2825 Only) on page 2-21.
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 device's
documentation.
The host adapter is firmly seated and secured in a VL-Bus slot.
The SCSI devices and host adapter are each set to a unique
SCSI ID (0-7). See Setting SCSI IDs on page 2-17.
Check SCSI bus termination—the ends of the SCSI bus must be
terminated. See Terminating the SCSI Bus on page 2-15.
If your problem is still not resolved, continue with the next section.
