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

1 Plan your SCSI device connections (see
Chapter 3.1).
2 Shut 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.
3 Open the computer case.
4 tall the ATTO ExpressPCI host adapter in
Ins
any open PCI expansion slot. If you have
questions about how to install an expansion
card in your system, consult your
computer's documentation.
NOTE 64/32-bit Mode: The jumpers J1 and J2, when
installed vertically, ensure ATTO ExpressPCI 64-bit cards
work correctly in 32-bit mode in all 32-bit PCI slots. These
jumpers do not force the ExpressPCI card to operate in
32-bit mode. If placed in a 64-bit mode, the ExpressPCI
5 ATTO Technology ExpressPCI Ultra3 SCSI Host Adapters Installation and Operation Manual
card will still function in a 64-bit slot. However, removing
jumpers may cause the ExpressPCI card to function
incorrectly in some 32-bit PCI slots.

jumpers J1 and J2 with an ExpressPCI 64-bit card.

5 Replace the computer cover.
6 Connect SCSI devices by inserting a SCSI
cable to the connector on the ATTO
ExpressPCI host adapter. Refer to
Exhibit 3.1-2 when selecting cables.
7 Power up your computer.
8 Set SCSI device termination. (see
Chapter 3.1)
9 Set 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.
10 ATTO 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.
11 If necessary, install drivers for your
operating system from the ATTO
ExpressPCI Utilities CD. Refer to
Chapter 3.2 for more information.
