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

Termination The SCSI bus is a chain of SCSI devices. The devices at both ends of any SCSI chain must be terminated for the SCSI bus to function correctly. A SCSI device chain can be configured in three different ways: internal, external and an internal/external SCSI device chain.. Remember an ATTO ExpressPCI Ultra2 SCSI adapter is also a SCSI device and may require termination depending upon the configuration. Be sure to use the correct terminator.
CHAPTER 4: HARDWARE INSTALLATION This chapter walks through the process of installing an ATTO ExpressPCI SCSI host adapter and attaching your SCSI devices to it. Please note to get the best performance from your ATTO ExpressPCI host adapters, use Ultra2/WIDE SCSI devices with the ATTO ExpressPCI Ultra2 host adapters. Before Installing your ATTO ExpressPCI SCSI Adapter 1. Plan your SCSI device connections.
Hardware Installation The ATTO ExpressPCI SCSI adapter installs easily into your system. Review system documentation to select an appropriate slot to install your SCSI adapter. The combined power consumption of your expansion cards must not exceed the limits specified for your system. If you have more than one expansion card installed, check the information that came with your cards to make sure that their power consumption is within the limits specified in your system documentation.
CHAPTER 5: TROUBLESHOOTING Try the following suggestions to troubleshoot the ATTO ExpressPCI SCSI adapter. • Check all cable connections to each device. Verify that all cables are in proper working condition. • Compare the termination of your system to the description in the Termination section of Chapter 3. • Verify that all of the devices attached to the ATTO ExpressPCI SCSI adapter have unique SCSI IDs. Remember the ATTO ExpressPCI SCSI adapter has a SCSI ID of 7 by default.
APPENDIX A: RADIO & TELEVISION INTERFERENCE The equipment described in this manual generates and uses radio frequency energy. If the ATTO ExpressPCI SCSI adapter is not installed and used properly; that is, in strict accordance with the manufacturer’s instructions, it may cause interference with radio and television reception.
The booklet How to Identify and Resolve Radio/TV Interference Problems prepared by the Federal Communications Commission is a helpful guide. It is available from the US Government Printing Office, Washington, DC 20402, Stock No. 004-00000345-4. Declaration of Conformity This applies to the ATTO ExpressPCI Single-Ended and Differential versions.

APPENDIX C: SCSI DEVICE & CABLING LIMITATIONS Due to the electrical noise incurred with high-speed data transfer rates, SCSI has cabling and device limitations. Table C-1 explains the maximum number of devices you may use relative to your cable distance. For example, take the single-ended distance in an UltraSCSI environment (Cells 3 & 4 in the single-ended bus length column).
