Adaptec 39106 manual Connecting Scsi Devices

Connecting SCSI Devices

Connecting SCSI Devices

Here are some examples of how you can connect internal and exter- nal SCSI devices to the Adaptec SCSI Card 39160. To achieve maxi- mum performance, attach the first device to the end connector of the cable (furthest from the SCSI card); attach other devices to the con- nectors that are closer to the SCSI card.

The first example shows Ultra160 and Ultra2 SCSI devices con- nected 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.

Caution: Do not connect SCSI devices to more than two of the three SCSI Channel A connectors at the same time.

The following example shows Ultra160 and Ultra2 SCSI devices con- nected to the internal connectors of both SCSI channels.
