3 Installing the ExpressPCI SCSI Host Adapter

You will need a basic understanding of SCSI before installing the ATTO ExpressPCI host adapter. Please refer to Chapter 2 for a list of SCSI-related web sites. For more detailed explanations of cabling, connectors and termination, see Chapter 3.1.

WARNING Remember to back up your system data before changing or installing hardware.

WARNING ATTO ExpressPCI host adapters contain components that are sensitive to electrostatic discharge (ESD). ESD can cause damage to the ExpressPCI host adapter. Please follow standard methods to avoid ESD.

System requirements

The ATTO Express PCI host adapter package contains the host adapter, the ATTO ExpressPCI Utilities CD and a warranty and registration card. If any of these items are missing, contact your ATTO authorized sales representative.

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

❖A computer with an available PCI slot.

❖SCSI devices

❖Cable(s) and terminator(s).

Installation

1Plan your SCSI device connections (see Chapter 3.1).

2Shut down the system and all peripherals before installing the adapter. After turning off the computer, leave the power cable plugged into a grounded outlet to discharge static electricity.

3Open the computer case.

4Install the ATTO ExpressPCI host adapter in any open PCI expansion slot. If you have

questions about how to install an expansion card in your system, consult your computer’s documentation.

5Replace the computer cover.

6Connect SCSI devices by inserting a SCSI cable to the connector on the ATTO ExpressPCI host adapter. Refer to Exhibit 3.1-2when selecting cables.

7Power up your computer.

8Set SCSI device termination. (see Chapter 3.1)

9Set SCSI IDs. Adapter default is 7.

Each device on the SCSI bus requires a unique SCSI ID. If installing a single device, make sure you do not assign it the same SCSI ID as your ATTO ExpressPCI SCSI adapter. Do not change the adapter ID if possible. For more information and ease in changing the ID, consult the ExpressPCI Utilities Installation and Operation Manual.

10ATTO ExpressPCI host adapters come preconfigured to operate properly in a variety of common system setups. However, some systems or setups may benefit by tuning the adapter for optimal performance. Use the ATTO ExpressPCI Utilities to change host adapter settings. Refer to Chapter 3.2 for more information.

11If necessary, install drivers for your operating system from the ATTO ExpressPCI Utilities CD. Refer to Chapter 3.2 for more information.
