Check the SCSI IDs
The Adaptec SCSI Card 29160 and each device you connect to it
must have a unique SCSI ID number ranging from 0 to 15. No
two devices can have the same number.
The Adaptec SCSI Card 29160 is preset to SCSI ID 7 and should
not be changed. If your computer will boot from a SCSI hard
disk, make sure the SCSI ID of that hard disk is set to 0. (Most
SCSI hard disks are preset to SCSI ID 0 at the factory.) The SCSI
IDs for internal devices are usually set with jumpers; SCSI IDs for
external devices are usually set with a switch on the back of the
device.
Terminate the Ends
To ensure reliable communication on the SCSI bus, the device at
the end of each cable, or the end of the cable itself, must have a
terminator installed (or enabled). Terminators must be removed,
or termination must be disabled, on devices between the ends of
each cable.
You can connect up to 15 SCSI devices to the Adaptec SCSI Card
29160. Before connecting devices, be sure to review Setting Up
SCSI Devices on page 4.
Connecting Internal Ultra160 and Ultra2 Devices
Connect internal Ultra 160 and Ultra2 SCSI devices to the inter-
nal LVD/SE connector on the Adaptec SCSI Card 29160. To do
this, use a 68-pin internal LVD cable like the one shown in Step 1
below. Follow these steps to connect the devices:

EVICES
We recommend that you keep your Ultra160 and
Ultra2 SCSI devices separate from your Ultra SCSI devices.
This allows the newer Ultra160 and Ultra2 SCSI devices to
transfer data at their maximum speed. (See Bus Segments on
the Adaptec SCSI Card 29160 on page 2.)
