The Adaptec SCSI Card 29160LP 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 Ultra160 and Ultra2 SCSI devices to the two 68-
pin Low Voltage Differential/Single-Ended (LVD/SE) connectors.
This installation guide explains how to:
•Install the Adaptec SCSI Card 29160LP
•Set up SCSI devices
•Connect SCSI devices
•Install Adaptec SCSI Card driver software
INTRODUCTION
If you connect singled-ended devices along with
Ultra160 or Ultra2 SCSI devices, the data transfer speed of
the Ultra160 or Ultra2 SCSI devices drops to the slower sin-
gle-ended transfer rate. Although the Adaptec SCSI Card
29160LP 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.

CHANGING THE BRACKET
The Adaptec SCSI Card 29160LP chips have a bracket designed to
fit in low-profile rack-mount server.
If you plan to use this card in a standard-height system, you will
need to change the bracket.
See the Adaptec SCSI Card 29160LP Technical Reference for more
information.
Discharge any static electricity build-up before handling the SCSI
card by touching a grounded metal object (such as 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.
CHANGING THE BRACKET
INSTALLING THE ADAPTEC SCSI CARD 29160LP
STEP 1
Turn OFF power to the computer and disconnect
the power cord.
WARNING
STEP 2
29160LPRevA.fm Page 2 Tuesday, May 2, 2000 4:04 PM
3
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.
Select an expansion slot that is compliant with PCI Rev. 2.1 or
higher, and that supports 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, place it on its side to make it easier to
install the Adaptec SCSI Card 29160LP.
STEP 3
Be careful when inserting the Adaptec SCSI Card
29160LP into a PCI slot. Some 32-bit slots do not accommo-
date 64-bit cards, and the card or slot may break if you use
force.

Insert the Adaptec SCSI Card 29160LP 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.
You may need to do several things to your SCSI devices before
you connect them to the Adaptec SCSI Card 29160LP:
•Check the SCSI IDs.
•Set the termination.
•Connect the power cables.
Since setup can vary from device to device, always refer to the
documentation supplied with the device for specific instructions.
Below are some guidelines for setting SCSI IDs and termination
on your devices. Refer to the Adaptec SCSI Card 29160LP User’s
Reference for more information on these topics.
Check the SCSI IDs
The Adaptec SCSI Card 29160LP 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.
STEP 4
SETTING UPSCSI DEVICES
29160LPRevA.fm Page 4 Tuesday, May 2, 2000 4:04 PM
5
If you want to configure your computer to 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 of the SCSI Bus
To ensure reliable communication on the SCSI bus, the device at
the end of the cable, or the end of the cable itself, must have
proper termination installed (or enabled). Terminators must be
removed, or termination must be disabled, on devices between
the ends of each cable.
Terminate LVD (Ultra160 and Ultra2) SCSI Devices
LVD SCSI devices are automatically unterminated. If you have
internal LVD SCSI devices, a special 68-pin internal LVD cable is
required to connect the devices. Internal LVD cables usually have
an LVD or Auto switching terminator built into the end of the
cable. With this type of cable, it is not necessary to terminate
individual internal LVD SCSI devices. If your cable does not have
a terminator built in, you must add a terminator to the end of the
cable.
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.
The Adaptec SCSI Card 29160LP is preset to SCSI ID 7
and should not be changed.

You can connect up to 15 SCSI devices to the Adaptec SCSI Card
29160LP. Before connecting devices, be sure to review Setting Up
SCSI Devices on page 4.
Connecting Internal SCSI Devices
Connect internal SCSI devices to the internal LVD/SE 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 the devices:
Locate a 68-pin internal LVD SCSI cable, which has flat,
laminated wires, as shown below.

CONNECTING SCSI DEVICES
If you connect single-ended SCSI devices along with
Ultra160 or Ultra2 SCSI devices, the data transfer speed
drops to the slower single-ended rate.

Plug the nonterminated end of the cable to the internal LVD/SE
connector.
Plug the internal devices to the other cable connectors, starting
with the connector at the terminated end of the cable.
STEP 2
STEP 3
Internal Ultra2 and Ultra160 SCSI devices come from
the factory with termination disabled and cannot be changed.
Proper SCSI bus termination is provided by the terminator at
the end of the LVD SCSI cable.

Connect a power cable from your computer’s internal power
supply to each internal SCSI device.
Connecting External SCSI Devices
Connect external SCSI devices to the 68-pin external VHDCI
LVD/SE SCSI connector. Each external device requires a 68-pin
external LVD SCSI cable.
Follow these steps to connect external SCSI devices:
Connect one end of the external LVD SCSI cable to the external
LVD/SE connector on the Adaptec SCSI Card 29160LP.
STEP 4
We r ecom m en d th a t you c o n ne ct only Ultra160 and
Ultra2 SCSI devices to the external SCSI connector. If you
also attach slower Ultra SCSI devices, the data transfer speed
of the Ultra160 and Ultra2 SCSI devices drops to the speed of
the slower devices.

Connect the other end of the external SCSI cable to a SCSI
connector on the back of an external SCSI device.
If you are installing only one external device, terminate the
device and skip to Step 4.
Connect other external devices by cabling each device to the
previous one, as shown below. Terminate only the device at the
end of the chain.
Connect power cables to all external devices and to the computer.
