Adaptec SCSI Card 29160 User’s Reference
Connecting SCSI Devices
Here are some examples of how you can connect internal and exter-
nal 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.
The following example shows Ultra160 and Ultra2 SCSI devices con-
nected to the 68-pin LVD/SE internal and external connectors.
