1.6 SCSI Cabling Limitations
Maximum total allowable cable length for a differential SCSI interface is 82 feet (25 meters). This distance
must be measured from the controller to the last device on the bus. Remember to add 12 inches for the
internal cable of each subsystem. Cables provided are 110 ohm twisted pair. If you are using a cable of
unknown composition, we suggest you replace it with the one provided by Tandem Computers. When
ordering, please reference one of the following part numbers:
517-010W* 517-025W* 517-050W* 517-075W*
*010, 025, 050 and 075 refer to cable length in feet
