Adaptec SCSI Card 19160 CONNECTING SCSI DEVICES You can connect up to 15 SCSI devices to the Adaptec SCSI Card 19160. Before connecting devices, be sure to review Setting Up SCSI Devices on page 5. For additional details on connecting devices, refer to the Adaptec SCSI Card 19160 User's Reference. Connecting Internal LVD (Ultra160 and Ultra2) SCSI Devices Connect internal LVD SCSI devices to the internal LVD/SE connector on the Adaptec SCSI Card 19160. To do this, use a 68-pin internal LVD cable like the one shown in Step 1 below. Follow these steps to connect the devices: NOTE We recommend that you keep your LVD SCSI devices separate from your SE (Ultra SCSI) devices. This allows LVD SCSI devices to transfer data at their maximum speed. (See Bus Segments on the Adaptec SCSI Card 19160 on page 2.) STEP 1 Locate a 68-pin internal LVD SCSI cable, which should have twisted wires as shown below to support LVD devices. Terminated End Nonterminated End 7
