Connecting to the SCSI Bus

Connecting to the SCSI Bus

You are now ready to connect the adapter to the SCSI bus.

Table 2-3. Connector and Cable Requirements

Connectors	68-pin Euro style SCSI:
	Shielded - external or internal cabinet
	applications
	Non-shielded- internal cabinet
	applications only
Bus Cable	68-conductor, flat ribbon or discrete:
	Single-ended:
	Type - Twisted pair only
	Shielding - match with connector
	Max bus length - 6 meters
	Differential:
	Type - twisted pair only
	Shielding - match with connector
	Max bus length - 25 meters

Single-ended and differential SCSI devices are

! electronically incompatible and cannot be mixed on the

Caution same physical bus. Mixing single-ended and differential SCSI devices on the same bus can cause permanent damage to both the peripherals and the PCI adapter.

Cables of different impedance should not be mixed on

! the same physical bus.
