Terminator power

You usually will not need to change this option and can normally leave the drive configured as it was shipped from the factory. For information about how to change the terminator power option on your drive, refer to the appropriate drive-specific section.

I/O circuits and data path widths

“W,” “WC,” “LW,” and “LC” models have a “wide” (16-bit) SCSI data bus rather than the standard (non-wide) 8-bit SCSI data bus; however, you can use these wide drives on a standard (non- wide) 8-bit data bus using a terminated 68-pin to 50-pin SCSI cable (not applicable to “WC” or “LC” drives which are not to be connected into the system via cable).
