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.
