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).
