CHAPTER 1: WELCOME

Congratulations on your purchase of ATTO ExpressPCI Ultra2 SCSI adapter. The

ATTO ExpressPCI SCSI adapter, featuring Advanced Data Streaming (ADS)

technology, represents a significant leap in performance technology for Macintosh®and

PC users. The ATTO ExpressPCI adapter offers you the flexibility of using it with either

your Macintosh or PC!

This chapter is an overview of the ATTO ExpressPCI Ultra2 SCSI host adapter and

installation process. To ensure your ATTO ExpressPCI Ultra2 SCSI adapter operates

at peak performance, read this manual before attempting installation. The short time

spent reading these instructions will help you install your ATTO ExpressPCI Ultra2

SCSI adapter correctly and with minimal effort.

Unpacking

The ATTO ExpressPCI Ultra2 package contains the following items:

•ATTO ExpressPCI Ultra2 SCSI Adapter

•ATTO ExpressPro-Tools CD

•Warranty and Registration Card

If any items are missing, please contact ATTO Technical Support.

What is ATTO ExpressPCI?

ATTO Technology is proud to present the ATTO ExpressPCI SCSI adapter featuring

Advanced Data Streaming (ADS) technology for your PCI based computer. In

addition to this new technology, ATTO ExpressPCI Ultra2 is compatible with

Macintosh and PC based computers. This explosive combination will allow you to

achieve the ultimate in power and performance. Compatible with all popular SCSI

devices, ATTO ExpressPCI will dramatically increase the performance of your disk-

intensive applications such as digital video, prepress, multimedia and real-time

environments.

The ATTO ExpressPCI family of Ultra2 SCSI adapters consists of two different

models:

•Single Channel Low Voltage Differential/Single-Ended - ExpressPCI UL2S

•Dual Channel Low Voltage Differential/Single-Ended - ExpressPCI UL2D

Page 2ATTO Technology, Inc.

ATTO ExpressPCI Ultra2 adapters unleash the power of Ultra2 SCSI by eliminating

SCSI management overhead and increasing SCSI transfer rates, while providing an

easy performance upgrade path for your existing SCSI-1, SCSI-2 and SCSI-3 drives.

Bus Master capabilities allow ATTO ExpressPCI SCSI host adapters to transfer data

directly between the computer’s RAM and the SCSI bus without using the CPU. This

frees all the CPU’s processing power for running demanding applications.

Plug and Play

The ATTO ExpressPCI Ultra2 SCSI adapter’s plug and play technology eliminates

configuration worries. No need to even set termination! Insert the ATTO ExpressPCI

Ultra2 SCSI adapter into your PCI based computer and you are ready to work!

However, should you need to alter the host adapter’s configuration, your ATTO

ExpressPCI Ultra2 SCSI adapter comes with the state-of-the-art ExpressPro-Tools

utilities to configure ATTO ExpressPCI Ultra2 SCSI adapters with ease.

SCSI Manager 4.3 Compatible

Macintosh eliminates connectivity hassles with the full support of the Asynchronous

I/O capabilities of SCSI Manager. This means you can attach any device to your

ATTO ExpressPCI Ultra2 SCSI adapter that has a SCSI Manager 4.3 compatible

driver. This support allows you to leverage your current equipment investment.

Installation Requirements

To successfully install and use your ATTO ExpressPCI Ultra2 SCSI adapter you need:

•A Mac®OS or PC compatible computer with an available PCI expansion

slot.

•Your complete ATTO ExpressPCI package.

•SCSI devices conforming to the SCSI-1, SCSI-2, SCSI-3 or Ultra2 standard.

About This Manual

This user’s manual combines why and how things are done, to make installing your

ATTO ExpressPCI Ultra2 SCSI adapter quick and easy.

This manual is written with the assumption the user has:

•A working knowledge of the Macintosh®and/or PC operating system(s).

•A working knowledge of SCSI driver/termination technology.

CHAPTER 2: GETTING A FAST START

If you have experience installing PCI SCSI adapters, the procedures in this chapter

are adequate to install an ATTO ExpressPCI Ultra2 SCSI adapter. However, if you

have no experience installing PCI SCSI adapters, first review Chapter 3, Cabling and

Termination. This chapter explains how to prepare hardware before installing the

ATTO ExpressPCI Ultra2 SCSI adapter. Once you have read Chapter 3, proceed to

Chapter 4, Hardware Installation. This chapter explains how to actually install the

ATTO ExpressPCI Ultra2 SCSI adapter.

ATTO ExpressPCI Quick Installation For Macintosh

1. Install your ATTO ExpressPCI Ultra2 SCSI adapter in a PCI expansion slot.

For questions concerning installation of an expansion card in your system,

consult your computer’s documentation. Most installations will use the ATTO

ExpressPCI SCSI adapter with no additional setup.

2. Physically install the SCSI devices using unique SCSI IDs and proper

termination.

3. Install the ExpressPro-Tools utilities software.

4. If necessary, use ExpressPro-Tools to create standard partitions for any new

drives.

ATTO ExpressPCI Quick Installation For PC

1. Decide which device interconnect cables and terminators you will use

(Internal/External/or both).

2. Set the termination for each of your SCSI devices.

FNote: Only the devices at each end of the SCSI bus are terminated.

Please remember, depending upon device configuration, the

ATTO ExpressPCI host adapter could be one of the devices at

the end of your SCSI bus.

WARNING

Backup your system data as a general precaution whenever changing or installing hardware.

ATTO ExpressPCI Ultra2 User’s Manual Page 5

3. Assign a unique SCSI ID # for each of your SCSI devices.

FNote: The ATTO ExpressPCI host adapter occupies SCSI ID # 7. Use

IDs 0-6 and 8-15 for your devices.

4. Install the ATTO ExpressPCI host adapter card in a PCI expansion slot. Most

installations require no additional setup.

5. Physically install the SCSI devices.

6. Connect device cabling.

7. If alternate settings are required/requested, configure the ATTO ExpressPCI

host adapter using the ATTO ExpressPCI Utilities (included on the

ExpressPro-Tools CD).

CHAPTER 3: CABLING AND TERMINATION

ATTO ExpressPCI Ultra2 SCSI host adapters are designed to operate with either low

voltage differential or single-ended devices. When connected to single-ended devices,

ATTO ExpressPCI Ultra2 negotiates to Ultra/WIDE transfer rates of 40 Mbytes/sec.

per channel. When connected to Ultra2/WIDE devices, ATTO ExpressPCI Ultra2

negotiates to Ultra2/WIDE transfer rates of 80 Mbytes/sec. per channel.

To determine your ATTO ExpressPCI Ultra2 SCSI host adapter model, check the

label located on the serial number end of the product box. The model you have will

be printed on the barcode label. After determining whether you are using a single

channel or dual channel model, the next step in the cabling and termination process is

to identify whether SCSI devices will be installed internally or externally. This

determines which cables are used and how to connect your SCSI device terminators.

Cabling for the ATTO ExpressPCI UL2S & UL2D SCSI

Adapters

The ATTO ExpressPCI UL2S has one industry standard 68-pin “P” (16-bit) VHDCI

(Very High Density Cabled Interconnect) cable connector for external device

connections and one 68-pin “P” (16-bit) cable connector for internal device

connections. The ATTO ExpressPCI UL2D has two industry standard 68-pin “P” (16-

bit) VHDCI cable connectors.

By definition, the Ultra2 SCSI specification limits the total bus cable length to 12

meters or approximately 38 feet (this is a combined figure of both internal and

external cable lengths). Try to keep cable lengths as short as possible to ensure higher

signal quality and performance.

If using a combination of Wide 16-bit devices and Narrow 8-bit devices on the same

connector, Wide devices must be connected first (closest to the connector), followed

by the Narrow devices. Please refer to the documentation for your SCSI devices to

determine if device is Wide or Narrow, and if it is an UltraSCSI or Ultra2 SCSI

device.

Cable Types

With all varieties of SCSI, be sure to use high quality SCSI-3 rated, well-insulated

SCSI cables to ensure error free communications. The following illustrations depict

the types of internal and external cable connectors you may come across.
