About SCSI adapter card termination
To connect internally-mounted SCSI devices, the SCSI adapter card’s on-board
internal SCSI termination must be switched ON. With most cards, this is done
automatically. If your SCSI adapter card requires that you manually disable
internal termination, refer to the documentation that came with it.
