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.
