This installation guide tells you how to install either the Adaptec®
PowerDomain®29160 or 29160N SCSI PCI card in the Power
Macintosh®and how to connect internal and external SCSI
devices to it.
The 29160/29160N card is fully compatible with Mac OS 8.6
through 9.X; it will support Mac OS X when available.
You can connect up to 15 SCSI devices to the Adaptec
PowerDomain 29160 and 29160N cards. Both cards are capable
of a maximum data throughput rate of 160 MB/sec. for newer
LVD (Low Voltage Differential) SCSI devices that can operate at
that speed.
The cards also support older SE (Single-Ended) SCSI devices that
run at slower speeds. The term SE SCSI devices includes SCSI-1,
SCSI-2, Fast, and Ultra SCSI devices. Adaptec's SpeedFlex™ tech-
nology makes it possible to connect both older and newer SCSI
devices to your Adaptec PowerDomain 29160 or 29160N card
and to operate all devices at their maximum possible throughput.
This is explained in detail in the sections on connecting various
kinds of SCSI devices.
INTRODUCTION
In this Installation Guide, the term “LVD SCSI devices”
means both Ultra2 SCSI and Ultra160-LVD SCSI devices.

Adaptec PowerDomain 29160/29160N
You can connect as many as 15 SCSI devices—such as hard disk
drives, scanners, and CD-ROM drives—to each Adaptec Power-
Domain 29160/29160N installed in your Power Macintosh.
However, before connecting the devices, you may need to do the
following:
•Change SCSI IDs if two or more devices share the same
SCSI ID
•Enable or disable termination
Following are some guidelines for setting SCSI IDs and termina-
tion on SCSI devices. Because setup can vary from device to
device, always refer to the device documentation for specific
instructions.
Understanding SCSI
SCSI (pronounced “scuzzy”) is an acronym for Small Computer
System Interface. SCSI is an industry standard computer inter-
face for connecting SCSI devices, such as hard disk drives,
CD-ROM drives, and scanners, to a common SCSI bus.
A SCSI bus is an electrical pathway consisting of a SCSI card, such
as the Adaptec PowerDomain 29160 and 29160N, installed in a
computer and one or more SCSI devices connected to the card by
SCSI cables.
For the SCSI bus to function properly, SCSI IDs must be assigned
to the SCSI devices and the SCSI PCI card, and the SCSI bus
must be properly terminated.
SETTING UP SCSI DEVICES
If you are not familiar with SCSI concepts or terminol-
ogy, or if you would like a quick review of SCSI technology,
read this section. If you know what SCSI is all about, skip to
the next section, Connecting SCSI Devices on page 12.

Installation Guide
Setting SCSI IDs
A SCSI ID uniquely identifies each SCSI device on the SCSI bus
and determines priority when two or more devices are trying to
use the SCSI bus at the same time.
Each device attached to the Adaptec PowerDomain 29160 or
29160N, as well as the SCSI PCI card itself, must be assigned a
unique SCSI ID from 0 to 15. The Adaptec PowerDomain 29160
and 29160N IDs are preset to SCSI ID 7—the highest priority on
the SCSI bus—and should not be changed. Most SCSI hard disk
drives come from the factory preset to SCSI ID 0 or 6.
The SCSI IDs for internal devices are usually set with jumpers
(small removable plugs whose location determines some aspect
of a device’s configuration); external devices are usually set with a
switch on the back of the device. See the illustrations below for
examples of three methods for setting the SCSI ID.

Adaptec PowerDomain 29160/29160N
Terminating the SCSI Bus
To ensure reliable communication on the SCSI bus, terminators
must be installed (or enabled) on the devices at the physical ends
of the SCSI bus. The terminators on all devices between the phys-
ical ends of the SCSI bus must be removed (or disabled).
Following are general guidelines for terminating a SCSI bus:
•Termination is usually controlled by installing or removing a
SCSI terminator. On some SCSI devices, termination is con-
trolled by setting a switch on the back of the device.
•Some SCSI devices come from the factory with termination
enabled, but most LVD SCSI devices come with termination
disabled.
There are various methods for terminating hard disks and other
SCSI devices. If you are not sure how to set termination for your
particular device, refer to the device documentation.
The illustration below shows three possible areas where a SCSI
bus is terminated:

Block terminator connected
to a SCSI device

Bus Segments on the Adaptec SCSI Card
The Adaptec PowerDomain 29160/29160N SCSI PCI cards fea-
ture Adaptec’s SpeedFlex technology. SpeedFlex technology
allows newer, faster LVD SCSI devices and slower SE SCSI devices
to run simultaneously on different segments of the SCSI bus.
(See Achieving Maximum Performance with SpeedFlex on page 26
for more information.)
You can connect a total of 15 SCSI devices to either the Adaptec
PowerDomain 29160 or 29160N.
Connecting Internal 68-Pin LVD SCSI Devices
Use a 68-pin LVD cable to connect internal LVD SCSI devices to
the 68-pin internal LVD/SE connector on the Adaptec
PowerDomain 29160 or 29160N. The cable should look similar
to the ones shown in Step 1 following.
CONNECTING SCSI DEVICES
SCSI devices can be connected to all four SCSI connec-
tors on the Adaptec PowerDomain 29160, or all three
connectors on the PowerDomain 29160N, at the same time.
We recommend that you connect only LVD SCSI
devices to the 68-pin LVD/SE connectors. If you try to con-
nect SE SCSI devices and LVD SCSI devices to the same SCSI
bus segment, all devices will run at the slower Ultra SCSI
speed. (See Achieving Maximum Performance with SpeedFlex
on page 26 for more information about bus segments.)

Adaptec PowerDomain 29160/29160N
Locate the 68-pin internal LVD SCSI cable, which should look
similar to one of the cables shown below. Cables can have twisted
wires (first example) or flat, laminated wires (second example).
STEP 1
Internal cable connec-
tors are keyed or shaped so
you can attach them only
one way.
To attach a trapezoidal-
shaped cable connector such
as the 68-pin connector,
align the cable connector
with the SCSI card connec-
tor or SCSI device
connector, and press the
cable connector firmly into
the SCSI card or SCSI device
connector.

Plug the remaining connector(s) into the internal LVD SCSI
devices.
After you have connected all your inter-
nal LVD SCSI devices to the Adaptec
PowerDomain 29160 or 29160N, plug a
power cord bundle from the computer
into each device.
If you want to install internal Fast/Ultra-SE SCSI devices, go to
the next section, Connecting Internal 50-Pin Fast/Ultra-SE SCSI
Devices on page 17.
If you want to install internal Ultra/Wide SCSI devices on the
29160, go to the section Connecting Internal 68-Pin SE SCSI
Devices (29160 only) on page 20.
STEP 3
The illustration shows the 29160 card. The procedure is
the same for the 29160N.
Internal LVD 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.

Installation Guide
When you have installed all your internal devices, close the cover
or replace the cover on the computer case. (Refer to the instruc-
tions in Setting Up Your Power Macintosh.)
If you will not be installing external devices, connect all power
cables to the computer and any previously attached external
devices, and plug the cables into an electrical outlet. Turn ON all
external devices first—before you turn ON the computer.
If you intend to install external devices, go to the section titled
Connecting External 68-pin LVD/SE SCSI Devices (29160 only) on
page 22 or the section titled Connecting External 50-pin
Fast/Ultra-SE SCSI Devices (29160N only) on page 25.
If the computer or the devices do not work properly, turn to Trou-
bleshooting on page 28.

Devices
Use a 50-pin internal Ultra SCSI cable to connect Fast/Ultra-SE
SCSI devices that have standard 50-pin connectors to the 50-pin
internal Fast/Ultra-SE connector on the Adaptec PowerDomain
29160 or 29160N.
Locate a 50-pin internal Ultra SCSI cable. It should look similar
to the cable in the following illustration.
STEP 1
Internal cable connec-
tors are keyed or shaped so
you can attach them only
one way.
To attach a keyed cable con-
nector, align the cable

the SCSI PCI card connector
or SCSI device connector,
and press the cable connec-
tor firmly into the SCSI PCI
card or SCSI device
connector.
