3.Connect the other end of the cable to a terminated Ultra/Fast Narrow SCSI device. Pin-1 must match on all connections.

4.If you have other Ultra/Fast Narrow SCSI devices, attach them to the connectors between the two ends of the cable. Be sure these other devices are unterminated.

5.Connect a power cable from your computer’s internal power supply to each internal SCSI device.

2.6.4 Connecting External SCSI Devices

You can connect external Ultra160 and Ultra2 SCSI devices to the 68-pin external LVD/SE SCSI connector. The external devices will require a 68-pin VHDCI external LVD SCSI cable.

NOTE: We recommend that you connect only Ultra160 and Ultra2 SCSI devices to the external SCSI connectors in order to achieve the maximum data transfer rate.
