Connecting SCSI Devices Connecting SCSI Devices Here are some examples of how you can connect internal and external SCSI devices to the Adaptec SCSI Card 39160. To achieve maximum performance, attach the first device to the end connector of the cable (furthest from the SCSI card); attach other devices to the connectors that are closer to the SCSI card. The first example shows Ultra160 and Ultra2 SCSI devices connected to internal and external SCSI connectors of both SCSI channels. Note the built-in terminators at the end of the internal LVD SCSI cables. The last external SCSI device on each SCSI channel must be terminated with an LVD/SE terminator plug to ensure that all devices will operate at their maximum speed.

The following example shows Ultra160 and Ultra2 SCSI devices connected to the internal connectors of both SCSI channels. Built-in terminator T Built-in terminator T 25
