Check each cable connection on every device.

Loose or broken cables are often the cause of
errors or problems.

Check that your SCSI devices are plugged
into an AC outlet and are turned on before you add
power to your computer.

Verity that all devices and busses are properly
terminated. See Chapter 3.1 for more
information.

Verify that all devices attached to the ATTO
ExpressPCI SCSI adapter have unique SCSI IDs.
ATTO ExpressPCI SCSI adapters have a default
SCSI ID of 7.

If the same device shows up at several
different SCSI IDs, either its SCSI ID is set the
same as the ATTO ExpressPCI SCSI ID, or the
cable is defective.

If a device doesn’t appear and cables and
termination are set properly, try lengthening the
SCSI Reset Delay using the ExpressPCI Utilities
found on the CD that came with your host adapter.

PC users should make sure that SCSI adapter
firmware and Windows drivers are at the same
revision level. Unless indicated otherwise, the
latest drivers and firmware can be downloaded
