Adaptec SCSI Card 29160 User's Reference Connecting SCSI Devices Here are some examples of how you can connect internal and external SCSI devices to the Adaptec SCSI Card 29160. To achieve maximum performance, attach the first device to the end connector (furthest from the SCSI card); attach other devices to the connectors that are closer to the SCSI card. The first example shows SCSI devices connected to all four internal and external connectors. Note the built-in terminator on the end of the internal LVD SCSI cable. The last external SCSI device must be terminated with an LVD/SE terminator plug to ensure that all devices will operate at their maximum speed.
