Adaptec SCSI Card 29160
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) connec-
tors. 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.
This installation guide explains how to
•Install the Adaptec SCSI Card 29160
•Set up SCSI devices
•Connect SCSI devices

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.
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).

Adaptec SCSI Card 29160
Discharge any static electricity build-up before handling the SCSI
card by touching a grounded metal object (like the exposed metal
parts on the back of your computer).
After you turn off your computer and unplug the power cord,
remove the cover from the computer.
Locate an unused 64-bit PCI expansion slot and remove the
expansion slot cover. If the computer does not have a 64-bit slot,
you can install the card in a 32-bit PCI slot. (The expansion slot
must be compliant with PCI Rev. 2.1 or higher and must support
Bus Mastering.) Save the slot cover screw for use in Step 4.

Installation Guide
Computers may have vertical or horizontal expansion slots. Refer
to your computer manual to locate the PCI slots. If your com-
puter is a tower model, lay it on its side to make it easier to install
the Adaptec SCSI Card 29160.
Insert the Adaptec SCSI Card 29160 into the PCI expansion slot;
press down firmly until the card clicks into place, then replace the
slot cover screw. When installed properly, the card should appear
level with the expansion slot, as shown below.
Be careful when inserting the Adaptec SCSI Card
29160 in a PCI slot. Some 32-bit slots will not accommodate
it, and the card may break if you force it into the slot.

Adaptec SCSI Card 29160
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 m i n a t e t h e E n d 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 termi-
nation, and mounting devices in your computer. Refer to the
Adaptec SCSI Card 29160 User’s Reference for more information
on these topics.
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

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 ter-
mination 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, termi-
nation 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 avail-
able drive bay inside your computer, as shown below. Refer to
your computer and device documentation for instructions on
installing devices inside your computer.

Adaptec SCSI Card 29160
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 7. For additional details on connecting
devices, refer to the Adaptec SCSI Card 29160 User’s Reference.
Connecting Internal LVD SCSI Devices
Connect internal LVD SCSI devices to the internal 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:
Locate a 68-pin internal LVD SCSI cable, which may have either
twisted wires as shown below or flat, laminated wires.
CONNECTING SCSI DEVICES
SCSI devices can be connected to all four SCSI
connectors on the Adaptec SCSI Card 29160 at the same time.
We recommend that you keep your LVD SCSI devices
separate from your SE (Ultra SCSI) devices. This allows LVD
SCSI devices to transfer data at their maximum speed. (See
Bus Segments on the Adaptec SCSI Card 29160 on page 4.)

Adaptec SCSI Card 29160
Connect power cables to all external devices and to the computer.
To use the Adaptec SCSI Card 29160, the card’s driver software
must be installed for your operating system (for example,
Windows®98, Windows NT®, Novell NetWare, etc.). The
Ultra160 Family Manager Set contains driver software for many
of the popular operating systems.
Refer to the Ultra160 Family Manager Set User’s Guide and
Adaptec SCSI Card 29160 User’s Reference for instructions on
either installing driver software when installing your operating
system, or installing driver software when the operating system is
already installed.
STEP 4
ADAPTEC SCSI CARD DRIVER SOFTWARE
Operating system versions released after November,
1999, may have embedded driver support for the Adaptec SCSI
Card 29160. To determine if the card is supported by the oper-
ating system you are using, read the operating system manual
or contact the operating system vendor for information.

Installation Guide
If you have any problems while installing the Adaptec SCSI Card
29160, check the following items first:
•Are all SCSI devices powered on?
•Are all SCSI cables and power cables properly connected?
•Does each device on the SCSI bus have a unique SCSI ID?
•Does the total SCSI cable length exceed the maximum allow-
able length? (See the Adaptec SCSI Card 29160 User’s
Reference for more information.)
•Is the SCSI bus properly terminated?
If you are still unable to resolve a problem, refer to the Adaptec
SCSI Card 29160 User’s Reference, or the Adaptec Web site at
http:\\www.adaptec.com for additional troubleshooting
information.
