The Adaptec SCSI Card 29160 Ultra160 SCSI controller enables
you to connect up to 15 SCSI devices—such as hard disk drives,
scanners, and CD-ROM drives—to any Intel-based computer
with 32-bit or 64-bit PCI expansion slots. You can connect newer
LVD SCSI devices (includes Ultra160 and Ultra2) to the two
68-pin Low Voltage Differential/Single-Ended (LVD/SE) connec­tors. You can also connect legacy SCSI devices to the 68-pin and
50-pin internal Single-Ended (SE) connectors.

Although the Adaptec SCSI Card 29160 is a 64-bit PCI card, it
also works in a 32-bit PCI slot. When installed in a 32-bit PCI
slot, the card automatically runs in the slower 32-bit mode.

Installation Guide

Bus Segments on the Adaptec SCSI Card 29160

The Adaptec SCSI Card 29160 features Adaptec SpeedFlex™
technology. SpeedFlex technology ensures that you get the best
performance from your LVD SCSI devices by electronically
isolating the primary LVD/SE segment from the secondary SE
segment on the SCSI bus. This allows the Adaptec SCSI Card
29160 to support LVD SCSI devices at speeds up to 160
MBytes/sec on the primary LVD/SE segment while at the same
time supporting Ultra (legacy) devices at speeds up to 40
MBytes/sec on the secondary SE segment. The following figure
shows the two SCSI segments.

OTE

If you attach Wide Ultra or Ultra SCSI devices to the
two connectors on the Primary LVD/SE segment, the data
transfer rate for all attached LVD SCSI devices will drop to
Ultra SCSI performance levels. However, if you attach

only

LVD SCSI devices to the two connectors on the Primary
LVD/SE segment, data will be transferred at the maximum
possible rate (80 MBytes/sec for Ultra2 devices and
160 MBytes/sec for Ultra160 devices).

There are several things you may need to do to your SCSI devices
before you connect them to the Adaptec SCSI Card 29160:

•

Check the SCSI IDs

•

Te r mi n a te th e E nd s

•

Mount the Devices

Since setup can vary from device to device, always refer to the
device’s documentation for specific instructions.

Below are some guidelines for checking SCSI IDs, setting termi­nation, and mounting devices in your computer. Refer to the

Adaptec SCSI Card 29160 User’s Reference

on these topics.

EVICES

for more information

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.

Terminating LVD SCSI Devices

LVD SCSI devices are automatically un-terminated. If you are
using internal LVD SCSI devices, a special 68-pin internal LVD
cable is required to connect the devices. Internal LVD cables

7

Installation Guide

usually have a terminator built into the end of cable. With this
type of cable, it is not necessary to terminate individual internal
Ultra160 and Ultra2 devices.

If you are using external LVD devices, be sure to use an LVD
terminator to terminate the last device in the chain. If you use a
single-ended, active terminator (sometimes called an Ultra SCSI
terminator) the SCSI devices will not operate at their maximum
speed and you will be limited to shorter total cable lengths.

Terminating Ultra SCSI and Fast/Wide SCSI Devices

On most internal Ultra SCSI and Fast/Wide SCSI devices, the ter­mination setting is controlled by setting a jumper or a switch, or
by physically removing or installing a resistor module(s). If you
are using an internal SCSI cable that has a built-in terminator,
you must disable termination on all internal devices connected to
the cable.

On most external Ultra SCSI and Fast/Wide SCSI devices, termi­nation is controlled by installing or removing a terminating plug.
For more information, refer to the documentation for each SCSI
device.

Mount the Devices

If you have internal SCSI devices, mount each device in an avail­able drive bay inside your computer, as shown below. Refer to
your computer and device documentation for instructions on
installing devices inside your computer.
