Installation Guide CONNECTING SCSI DEVICES You can connect a total of 30 SCSI devices to the Adaptec SCSI Card 39160,with up to 15 devices on each SCSI channel. Before connecting devices, be sure to review Setting Up SCSI Devices on page 4. Connecting Internal Ultra160 and Ultra2 Devices A special 68-pin internal LVD cable is needed to connect internal Ultra160 or Ultra2 SCSI devices. If your cables are not marked, you can identify most LVD cables as having twisted pairs of the flat ribbon cable between the device connectors. Some cables are laminated so that they lay flat. Internal LVD cables usually have a terminator built into the end of the cable. The Adaptec SCSI Card 39160 has two separate Ultra160 SCSI channels, as shown in the figure on page 1. Each channel has an internal LVD/SE connector to which you can connect internal SCSI devices. Follow these steps to connect your internal Ultra160 and Ultra2 devices: NOTE We recommend that you keep your Ultra160 and Ultra2 SCSI devices on a separate SCSI channel from your Ultra SCSI devices. This allows the newer Ultra160 and Ultra2 SCSI devices to transfer data at their maximum speed. STEP 1 Locate a 68-pin internal LVD SCSI cable, which may have either twisted wires or flat wires, as shown here. Terminated end Non-terminated end 6
