INSTALLATION GUIDE

ADAPTEC SCSI CARD 29320A

Introduction

The Adaptec SCSI Card 29320A enables you to connect up to 15
Low Voltage Differential (LVD) and/or 15 Single-Ended (SE) SCSI
devices—such as very large arrays of high-performance hard disk
drives, external storage subsystems, Ultra320/160 hard disk drives,
scanners, and CD-ROM drives—to any Intel-based computer with
64- or 32-bit PCI/PCI-X expansion slots.

The Adaptec SCSI Card 29320A has one internal and one external
68-pin LVD connector and two int ernal SE SCSI connectors (one
68-pin and one 50-pin).

Although the Adaptec SCS I Card 29320A is a 64-bit PCI/PCI-X
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 mo d e.

This installation guide explains ho w to:

■ Install the Adaptec SCSI Card 29320A

■ Set up SCSI devices

■ Connect SCSI devices

1

Installing the Adaptec SCSI Card 29320A

1 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).

Warning: Turn OFF power to the computer and disconnect
the power cord.

2 After you turn off your computer and unplug the power cord,

remove the cover from the computer.

3 Locate an unused 64-bit PCI/PCI-X 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 Adaptec
SCSI Card 29320A su p ports both 5V and 3.3V 64-bit slots. (The
expansion slot must be compliant with PCI Rev. 2.1 or PCI-X
Rev. 1.0 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/PCI-X slots. If
your computer is a tower model, lay it on its side to allow for
easier installation of the Adaptec SCSI Card 29320A.

Warning: Be careful when inserting the Adaptec SC SI Card
29320A in a PCI slot. Some 32-bit slots will not
accommodate it, and the card may break if you force it into
the slot.

4 Insert the Adaptec SCSI Card 29320A in the 64-bit (or 32-bit)

PCI or PCI-X 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.

Setting Up SCSI Devices

There are several things you may need to do to your SCSI devices
before you connect them to the Adaptec SCSI Card 29320A:

■ Check the SCSI IDs

■ Set the term ination

■ Connect the power cables

Since setup can vary from device to device, always refer to the
device’s documentation for specific instructions.

3

Following are some guidelines for setting SCSI IDs and termination
on your devices.

Check the SCSI IDs

The Adaptec SCSI Card 29320A 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 29320A 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; S C SI IDs for external devices
are usually set with a switch on the back of the device.

Terminate the Ends

T o ensur e 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.

Note: When connecting Ultra320/160 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 Ultra320/160 and Ultra2 SCSI
bus, the SCSI devices will not operate properly. For this
reason be sure that you have the necessary Ultra320/160 or
Ultra2 cable and terminator before installing the Ultra320/160
SCSI devices.

Connecting SCSI Devices

You can connect a total of 15 LVD and/or 15 SE SCSI devices to the
Adaptec SCSI Card 29320A. Before connecting devices, be sure to
review Setting Up SCSI Devices on page 3.

Connecting Internal Ultra320/160 and Ultra2 Devices

A special 68-pin internal LVD cable is needed to connect internal
Ultra320/160 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. Interna l LVD cables usually have a
terminator built into the end of the cable.

The Adaptec SCSI Card 29320A has one internal 68-pin LVD
connector and two internal SE connectors to which you can connect
internal SCSI devices, as shown in the figure on page 1.

Note: Adaptec recommends that you keep your Ultra320/160
and Ultra2 SCSI device s separate from your Ultra SCSI
devices. This allows the Ultra320/160 and Ultra2 SCSI
devices to transfer data at their maximum speed.

Follow these steps to connect your internal Ultra320/160 and
Ultra2 devices:

1 Locate a 68-pin internal LVD SCSI cable, which may have either

twisted wires or flat wires, shown as follows.

2 Plug the nonterminated end of the cable(s) to the internal LVD

connector.

3 Plug the internal Ultra320/160 and Ultra2 SCSI devices to the

other cable connectors, starting with the connector at the
terminated end of the cable.

Note: Internal Ultra320/160 and Ultra2 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.

4 Connect a power cable from your computer’s internal power

supply to each internal SCSI device.

6

Connecting Wide SCSI Devices

Connect internal Wide SCSI devices to the 68-pin internal SE Wide
SCSI connector. To do this, use a 68-pin Wide SCSI cable like the
one shown in Step 1 below. Follow these steps to connect the
devices:

1 Locate a 68-pin internal Wide SCSI cable.

2 Plug one end of the cable to the Wide SCSI connector on the

Adaptec SCSI Card 29320A.

3 Plug the other end of the cable to a terminated Ultra/Fast Wide

SCSI device.

4 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.

5 Connect a power cable from your computer’s internal power

supply to each internal device.

Connecting Internal Ultra/Fast Narrow Devices

Connect internal Ultra/Fast Narrow SCSI devices that have
standard 50-pin connectors to the 50-pin internal SE Narrow SCSI
connector. To do this, use a 50-pin internal Ultra Narrow SCSI
cable. Follow these steps to connect the devices:

1 Locate a 50-pin internal Ultra Narrow SCSI cable.

7

2 Plug one end of the cable to the 50-pin internal SE Narrow SCSI

connector on the Adaptec SCSI Card 29320A.

3 Plug the other end of the cable to a terminated Ultra/Fast

Narrow SCSI device.

4 If you have other Ultra/Fast Narrow SCSI devices, attach them

to the connectors between the two ends of the cable. Be sure
these other devices are unterminated.

5 Connect a power cable from your computer’s internal power

supply to each internal device.

Connecting External SCSI Devices

You can connect external Ultra320/160 and Ultra2 SCSI devices to
the 68-pin external LVD SCSI connector. Each external device will
require a 68-pin LVD external LVD SCSI cable.

Note: We recommend that you do not combine older SCSI
devices with the newer Ultra320/160 and Ultra2 SCSI devices
on the same SCSI channel of the Adaptec SCSI Card 29320A.

Follow these steps to connect your external SCSI devices:

1 Connect one end of an external SCSI cable to one of the external

Ultra320/160 connectors on the Adaptec SCSI Card 29320A.

3 Connect the other external SCSI devices by linking each device

to the previous one, as shown below. Terminate only the device
at the end of the chain.

4 Connect power cables to all external device(s) and to the

computer.

More Information About Termination

The last SCSI device on the end of each SCSI bus cable must be
terminated, and termination must be disabled for all other devices
in the middle of the cables. Ultra320/160 and Ultra2 SCSI devices
are automatically unterminated, but Ultra SCSI and Fast/Wide
SCSI devices do have termination that you must check. For more
information, refer to the documentation for each SCSI device.

If you are using external Ultra2 or Ultra320/160 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 terminator) the SCSI devices will not operate properly.

Troubleshooting

If you have any problems while installing the Adaptec SCSI Card
29320A, check the following items first:

■ Are all SCSI devices powered on?

■ Are all SCSI cables and power cables properly connected?

■ Does each device on each SCSI bus have a unique SCSI ID?

■ Does the total SCSI cable length exceed the maximum allowable

length?

■ Is the SCSI bus properly terminated?

If you are still unable to resolve a problem, contact the system
manufacturer for help.

Adaptec SCSI Card Driver Software

Note: To use the Adaptec SCSI Card 29320A, driver software

must be installed for your operating system. Installation of
the driver software varies depending on how and where you
purchased the Adaptec SCSI Card 29320A.

10

Preloaded Adaptec Drivers

If the Adaptec SCSI Card 29320A was included as part of a
computer system you purchased, the system already has the
appropriate Ad aptec driver preinstalled by the computer
manufacturer. No further action is necessary to install the driver.

Embedded Adaptec Drivers

Some operating systems have embedded driver support for the
Adaptec SCSI Card 29320A. To determine if the card is supported
by the operating system you are using, read the operating system
manual or contact the operating syst em vendor for inform ation.
