ADAPTEC SCSI CARD 29320LP

ASC-29320LP IG.fm Page 14 Wednesday, August 14, 2002 4:45 PM

The Adaptec SCSI Card 29320LP enables you to connect up to 15

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 29320LP is a single channel SCSI card

with a maximum throughput of 320 MB/sec. You can connect

Ultra320/160 and Ultra2 SCSI devices to the internal 68-pin Low

Voltage Differential/Single-Ended (LVD/SE) connector and the

external very high-density cable interconnect (VHDCI) connector.

Although the Adaptec SCSI Card 29320LP 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 mode.

This installation guide explains how to:

•Install the Adaptec SCSI Card 29320LP

•Set up SCSI devices

•Connect SCSI devices

INTRODUCTION

If you connect single-ended Wide Ultra/Ultra SCSI

devices to the same SCSI channel as Ultra320/160 and Ultra2

SCSI devices, the data transfer rate for the Ultra320/160 and

Ultra2 SCSI devices will drop to Ultra SCSI performance

levels.

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/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 29320LP supports 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 29320LP.

Insert the Adaptec SCSI Card 29320LP 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.

Be careful when inserting the Adaptec SCSI Card

29320LP in a PCI slot. Some 32-bit slots will not accommodate

it, and the card may break if you force it into the slot.

WARNING

STEP 4

ASC-29320LP IG.fm Page 3 Wednesday, August 14, 2002 4:45 PM

There are several things you may need to do to your SCSI devices

before you connect them to the Adaptec SCSI Card 29320LP:

•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.

Folowing are some guidelines for setting SCSI IDs and

termination on your devices.

Check the SCSI IDs

The Adaptec SCSI Card 29320LP and each device you connect to

it must have a unique SCSI ID number ranging from 0 to 15. No

two devices on the SCSI channel can have the same SCSI ID.

The Adaptec SCSI Card 29320LP 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. (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.

SETTING UPSCSI DEVICES

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.

NOTE

ASC-29320LP IG.fm Page 4 Wednesday, August 14, 2002 4:45 PM

You can connect a total of 15 SCSI devices to the Adaptec SCSI

Card 29320LP. Before connecting devices, be sure to review

Setting Up SCSI Devices on page 4.

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 ofthe 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 29320LP has one internal LVD/SE

connector to which you can connect internal SCSI devices.

Follow these steps to connect your internal Ultra320/160 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

Adaptec recommends that you keep your Ultra320/160

and Ultra2 SCSI devices separate from your Ultra SCSI

devices. If you connect a legacy SCSI hard disk drive to the

Adaptec SCSI Card 29320LP LVD/SE connectors, the

Ultra320/Ultra160 and Ultra2 SCSI hard disk drives will slow

to Ultra SCSI performance levels.

NOTE

STEP 1

Terminated end Nonterminated end

ASC-29320LP IG.fm Page 5 Wednesday, August 14, 2002 4:45 PM

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

LVD/SE connector.

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.

STEP 2

STEP 3

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.

NOTE

ASC-29320LP IG.fm Page 6 Wednesday, August 14, 2002 4:45 PM

Connect a power cable from your computer’s internal power

supply to each internal SCSI device.

Connecting External SCSI Devices

You can connect external Ultra320/160 and Ultra2 SCSI devices

to the 68-pin external LVD/VHDCI connector. Each external

device will require a 68-pin VHDCI external LVD SCSI cable.

Follow these steps to connect your external SCSI devices:

Connect one end of an external SCSI cable to the external

Ultra320/160 connector on the Adaptec SCSI Card 29320LP.

Connect the other end of the cable to a SCSI connector on the

back of an external device. If you are installing only one external

device, terminate the device and skip to Step 4.

ASC-29320LP IG.fm Page 7 Wednesday, August 14, 2002 4:45 PM

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.

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

computer.

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 anLVD 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.

allowable length?

•Is the SCSI bus properly terminated?

If you are still unable to resolve a problem, contact the system

manufacturer for help.

Preloaded Adaptec Drivers

If the Adaptec SCSI Card 29320LP was included as part of a

computer system you purchased, the system already has the

appropriate Adaptec 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 29320LP. To determine if the card is

supported by the operating system you are using, read the

operating system manual or contact the operating system vendor

for information.

TROUBLESHOOTING

ADAPTEC SCSI CARD DRIVER SOFTWARE

To use the Adaptec SCSI Card 29320LP, 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 29320LP.
