INTRODUCTION
With the Adaptec SCSI Card 29160N PCI-Ultra 160 SCSI controller,
you can connect up to 15 SCSI devices, such as hard disk drives, scan-
ners, CD-ROM drives,and tape drives, to any IBM-compatible comput-
er with PCI expansion slots. The following figure shows the SCSIcon-
nectors on the Adaptec SCSI Card 29160N.
The Adaptec SCSI Card 29160N is designed for computer
system original equipment manufacturers (OEMs). Use this
product with the original computer system designed by the OEM;
each OEM tailors their product specifications for their specific
design needs. Adaptec assumes no responsibility for incompatibility
or consequential damages if you use the Adaptec SCSI Card 29160N
in another computer system. All product support and services are
provided by the OEM.

Bus Segments on the
Adaptec SCSI Card 29160N
The Adaptec SCSI Card 29160N featuresAdaptec SpeedFlex™technol-
ogy. SpeedFlex technology ensures that you get the most performance
from your Ultra160 SCSI devices by electronically isolating the
Ultra160 SCSI segment from the Ultra SCSI segment on the SCSI bus.
With the SpeedFlex advantage,the Adaptec SCSI Card 29160N can
support Ultra160 SCSI devices at speeds up to 160 MBytes/sec while
simultaneously supporting Ultra (legacy) devices at speeds up to 40
MBytes/sec.
If you attach anyWide Ultra or Ultra SCSI devices to the
Ultra160-LVD connector, the data transfer rate for all devices can
run at various speeds. However, if you attach only Ultra160 and
LVD SCSI devices to the Ultra160-LVD connector, all devices will
operate at their maximum possible data transfer rate. That is,
Ultra2 devices will operate at a maximum of 80 MBytes/sec and
Ultra160 devices at a maximum of 160 MBytes/sec.

Discharge any static electricity build-up before handling your 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 PCI expansion slot and remove the expansion slot
cover. (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.
Computers may have vertical or horizontal expansion slots. Refer to
your computer manual to locate the PCI slots. If your computer is a
tower model, lay it on its side to allow for easier installation of the
Adaptec SCSI Card 29160N.
INSTALLING THE ADAPTEC SCSI CARD 29160N
Turn OFF power to the computer and disconnect the
power cord.

Insert the Adaptec SCSI Card 29160N into the PCI expansion slot;
press down firmly until it clicks into place, then replace the slot cover
screw.
If you refer to the device’s documentation for installation
instructions, be sure to return to this document to continue with
installation of the software driver.
NOTE
There are several things you need to do to your SCSI devices before
you connect them to the Adaptec SCSI Card 29160N:
• Set the SCSI IDs
• Set the termination
• Connect the power cables.
Since setup can vary from device to device, always refer to the device’s
documentation for specific instructions.
Below are some guidelines for setting SCSI IDs and termination on
your devices. Refer to the Adaptec SCSI Card 29160N User’s Reference
for additional information on SCSI IDs and termination.

Check the SCSI IDs
The Adaptec SCSI Card 29160N 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 29160N is preset to ID 7 and should not be
changed. If you boot from a SCSI hard disk, make sure the hard disk
SCSI ID is set to 0 or 1.Most SCSI hard disks come from the factory
preset to ID 0.The IDs for internal devices are usually set with jumpers;
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 a total of 15 SCSI devices to the Adaptec SCSI Card
29160N. Before connecting devices, be sure to also review Setting Up
SCSI Devices on page 4.
We recommend that you keep your Ultra160-LVD devices
separate from your Ultra devices. Connecting an Ultra
device to the Ultra 160-LVD SCSI connector forces the Ultra160-
LVD SCSI segment and any attached devices to drop down to Ultra
SCSI performance levels. (See Bus Segments on the Adaptec SCSI
Card 29160N on page 2.)
NOTE
Locate the 68-pin internal LVD SCSI cable, as shown below:
CONNECTING SCSI DEVICES
STEP 1
Internal Ultra 160-LVD SCSI Connector
(68-pin)
Connect internal LVD and Ultra 160-LVD devices using the internal
Ultra160-LVD connector. To do this, use a 68-pin internal LVD cable,
similar to the one shown in Step 1 below. Follow these steps to connect
your internal LVD and Ultra160 devices:
Terminator Connect to Ultra160-LVD and
Ultra2 Devices Connect to the Adaptec
SCSI Card 29160N

Plug the non-terminated end of the cable to the Ultra160-LVD
connector on theAdaptec SCSI Card 29160N.
Internal LVD SCSI or Ultra160 SCSI devices come from
the factory with termination disabled and cannot be changed.
Proper termination is provided by the terminator at the end of the
LVD SCSI cable.

SCSI or Ultra Narrow SCSI devices have standard 50-pin connectors.
To connect these internal devices, you will need a 50-pin internal Ultra
SCSI cable,similar to the one shown in Step 1 below.Follow these
steps to connect your standard internal Fast SCSI or Ultra Narrow
devices:
Locate the 50-pin internal Ultra SCSI cable.

INSTALLING DRIVER SOFTWARE
To use the Adaptec SCSI Card 29160N,driver software
must be installed for your operating system. Installation of
the driver software varies depending on how and where you pur-
chased the Adaptec SCSI Card 29160N.
Pre-loaded Adaptec Drivers
If the Adaptec SCSI Card 29160N was included as part of a computer
system you purchased, the system already has the appropriate Adaptec
driver pre-installed by the computer manufacturer. No further action
is necessary to install the driver.
