Tips for Troubleshooting
the Fast-Wide SCSI-2 Controller
Following are tips that may be helpful in troubleshooting problems reported in
POST Error Messages or Diagnostic Error Codes.
Check for improper or premature termination.
Improperly terminated devices can prevent the drive controller from
recognizing any of the connected devices. Premature termination means
that a device other than the last device in the chain terminates,
effectively cutting off the remaining devices from the chain.
Check for two SCSI devices with the same ID.
Typically, configuring a device for ID 0 does not require setting any
jumpers or switches. If the chain has more than one device as ID 0, it
can cause conflicts. You must verify the jumper or switch settings on all
your devices to ensure you do not have two SCSI devices with the same
ID.
Check for improper cabling.
Verify the cabling is within the requirements mentioned previously and
corresponds with any documentation provided with your SCSI devices.
Some devices might not be fully compatible with the SCSI specification
and can cause intermittent problems. Try to isolate the problem by
removing one device at a time from your configuration and noticing if
the problems repeat.
