The Adaptec SCSI Card 39160 enables you to connect up to 30
SCSI devices—such as very large arrays of high-performance
HDDs, external storage subsystems, clustered configurations,
Ultra160 hard disk drives, scanners, and CD-ROM drives—to
any Intel-based computer with 64- or 32-bit PCI expansion slots.
The Adaptec SCSI Card 39160 has two independent SCSI chan-
nels, each with a maximum throughput of 160 MBytes/sec. SCSI
Channel A (marked “CH 1/A” on the card) has two internal con-
nectors and one external connector. SCSI Channel B (marked
“CH 2/B” on the card) has one internal and one external
connector.
You can connect Ultra160 and Ultra2 SCSI devices to the 68-pin
Low Voltage Differential/Single-Ended (LVD/SE) connectors on
both SCSI channels. Or you can operate the newer Ultra160 and
Ultra2 devices at their maximum speed on Channel B while at
the same time using legacy SCSI devices on Channel A.
Although the Adaptec SCSI Card 39160 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.

•Install the Adaptec SCSI Card 39160

Installation Guide
Support for Older SCSI Devices
We recommend that if you have single-ended Ultra SCSI and ear-
lier SCSI devices you connect them to Channel A of the Adaptec
SCSI Card 39160 and that you connect newer Ultra2 and
Ultra160 SCSI devices to Channel B. This allows the Adaptec
SCSI Card 39160 to support newer Ultra160 and Ultra2 SCSI
devices at speeds up to 160 MBytes/sec while at the same time
supporting Ultra (legacy) devices at speeds up to 40 MBytes/sec.
It also allows you to use longer cable lengths for the newer SCSI
devices. (For more information about the maximum cable
lengths see the Adaptec SCSI Card 39160 User’s Reference.)
The Adaptec SCSI Card 39160 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 39160 in another computer system. All
product support and services are provided by the OEM.
If you connect Wide Ultra/Ultra SCSI devices to the
same SCSI channel as Ultra160 and Ultra2 SCSI devices, the
data transfer rate for the Ultra160 and Ultra2 SCSI devices
will drop to Ultra SCSI performance levels. To achieve maxi-
mum data transfer rates for the newer SCSI devices, be sure to
connect them on their own SCSI channel.

Adaptec SCSI Card 39160
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 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.
INSTALLING THE ADAPTEC SCSI CARD 39160
STEP 1
Turn OFF power to the computer and disconnect
the power cord.

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 allow for easier
installation of the Adaptec SCSI Card 39160.
Insert the Adaptec SCSI Card 39160 in the 64-bit (or 32-bit) 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.
There are several things you may need to do to your SCSI devices
before you connect them to the Adaptec SCSI Card 39160:
•Check 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.
Be careful when inserting the Adaptec SCSI Card
39160 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 39160
Below are some guidelines for setting SCSI IDs and termination
on your devices. Refer to the Adaptec SCSI Card 39160 User’s Ref-
erence for more information on these topics.
Check the SCSI IDs
The Adaptec SCSI Card 39160 and each device you connect to it
must have a unique SCSI ID number ranging from 0 to 15 on
each channel. No two devices on the same SCSI channel can have
the same SCSI ID.
The Adaptec SCSI Card 39160 is preset to ID 7 for each channel
and should not be changed. If you boot from a SCSI hard disk,
make sure the hard disk SCSI ID 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.
When connecting Ultra160 or Ultra2 SCSI devices, the
SCSI bus must be terminated either on the end of the cable
(with a permanent terminator) or with a separate terminating
connector. Ultra SCSI and earlier single-ended devices can
terminate the bus directly from the device. If you use an Ultra
SCSI terminator on an LVD Ultra160 and Ultra2 SCSI bus
you will force the bus to Single-ended mode, limiting the
speed and cable distance. For this reason be sure that you
have the necessary Ultra160 or Ultra2 cable or terminator
before installing the Ultra160 SCSI devices.

Installation Guide
You can connect a total of 30 SCSI devices to the Adaptec SCSI
Card 39160,with up to 15 devices on each SCSI channel. Before
connecting devices, be sure to review Setting Up SCSI Devices on
page 4.
Connecting Internal Ultra160 and Ultra2 Devices
A special 68-pin internal LVD cable is needed to connect internal
Ultra160 or Ultra2 SCSI devices. If your cables are not marked,
you can identify most LVD cables as having twisted pairs of the
flat ribbon cable between the device connectors. Some cables are
laminated so that they lay flat. Internal LVD cables usually have a
terminator built into the end of the cable.
The Adaptec SCSI Card 39160 has two separate Ultra160 SCSI
channels, as shown in the figure on page 1. Each channel has an
internal LVD/SE connector to which you can connect internal
SCSI devices. Follow these steps to connect your internal
Ultra160 and Ultra2 devices:
Locate a 68-pin internal LVD SCSI cable, which may have either
twisted wires or flat wires, as shown here.
CONNECTING SCSI DEVICES
We recommend that you keep your Ultra160 and
Ultra2 SCSI devices on a separate SCSI channel from your
Ultra SCSI devices. This allows the newer Ultra160 and
Ultra2 SCSI devices to transfer data at their maximum speed.

Installation Guide
Connecting Wide SCSI Devices
You can connect Wide SCSI devices to the internal LVD/SE con-
nectors. If you do this, we recommend that you connect them to
the SCSI Channel A LVD/SE connector and that you connect all
Ultra160 and Ultra2 devices to the SCSI Channel B connector.
Follow these steps to connect Wide SCSI devices:
Locate a 68-pin internal Wide SCSI cable.
Plug one end of the cable to the Channel A internal 68-pin con-
nector on the Adaptec SCSI Card 39160.
.
Plug the other end of the cable to a terminated Ultra/Fast Wide
SCSI device.
If you have other Ultra/Fast Wide SCSI devices, attach them to
the connectors between the two ends of the cable. Be sure these
other devices are unterminated.
Connect a power cable from your computer’s internal power sup-
ply to each internal device.
