2 Fibre Channel is a key technology for storage

Fibre Channel is a serial communications technology designed to transfer large amounts of data among
a variety of hardware systems over long distances. It is a key technology for applications that require
shared, high bandwidth access to storage.

Fibre Channel provides a logical, point-to-point,
serial channel for the transfer of data between a
buffer at a source device and a buffer at a
destination device. It moves buffer contents from
one port to another, without regard to the format
or meaning of the data so different upper level

protocols are able to run over Fibre Channel
hardware.

The Fibre Channel architecture is structured as a
hierarchical set of protocol layers. Defined within
these layers are rules for signal interfaces, serial
encoding and decoding, error control, frame
format and communications protocols.

3 Installing and updating drivers

Before installing your Celerity adapter, you must configure your system to recognize and use it by
installing drivers for your operating system.

Configure your system to recognize and use your
Celerity adapter by

another adapter in the system, disconnect
the FC cables from the adapter and
remove the adapter from the system, or
move the Celerity FC adapter to the PCI
slot that the previous adapter occupied.

b. Attach the appropriate FC cables to the

Celerity FC adapter.

4 Close the computer chassis

5 Turn on the power and restart Windows.

6 During the boot process, Windows detects your

Celerity FC adapter and the Found New
Hardware Wizard is displayed.

Follow the directions in the Found New
Hardware Wizard, selecting the default
settings for each adapter channel.

7 Insert the Celerity FC Installation disk when

asked to do so.

4 Hardware installation

You need a basic understanding of Fibre Channel before installing the Celerity FC host adapter. Please
refer to

Fibre Channel is a key technology for storage

on page 9 for a list of related websites.

CAUTIONCAUTION

Back up your system data before changing
or installing any hardware.

System requirements

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

To install and use the Celerity Fibre Channel host
adapter you need

• A computer with an available PCI, PCI-X or PCI
Express expansion slot

• The complete Celerity FC host adapter package

Fibre Channel address

Celerity FC adapters are configured with a unique
address designated by the Institute of Electrical
and Electronic Engineers. The WorldWide Port
Name (WWN) and Node Name are the two
components of the address assigned to Fibre
Channel products. This address, stored in flash
memory, allows the system to recognize the
Celerity host adapter as a unique part of your
configuration. The address is clearly marked on
the back of the board for easy identification.
Please keep a reference copy of the number in a
safe place or write in the space provided on this
page.

Celerity FC host adapter WWNs are assigned for
each channel. The WWN listed on your host
adapter is assigned to the first channel (0).
Sequential WWNs apply for additional channels.

WWN 0 all adapters

Installation

CAUTIONCAUTION

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

1 Install the latest drivers. Refer to Installing and

updating drivers on page 11.

2 Power down the computer and unplug the

computer from all power sources.

3 Open the case.

4

Install the Celerity FC host adapter in any open

PCI, PCI-X or PCI Express expansion slot. If
you have questions about how to install an
expansion card in your system, consult your
computer’s documentation.

Drawings of Celerity brackets begin on page 16
and drawings of boards begin on page 18.

Note

The Celerity FC-41XS, and FC-42XS host
adapters only fit in 3.3V slots.

The Celerity FC-42ES, FC-41ES and FC-41EL
fit into x4, x8, or x16 mechanical PCI Express
slots.

If you have trouble seating your adapter in a 32­bit PCI bus computer, check to make sure the
connector can accommodate 64-bit host
adapters.

5 Connect Fibre Channel devices by inserting a

Fibre Channel cable from the devices to the
connectors on the Celerity FC host adapter until
you hear a click.

6 Close the case on the computer and power it

5 Updating hardware flash

Your Celerity FC host adapter was flashed before shipment, but the flash memory may need to be
updated as new versions become available or if the factory-installed version becomes corrupt. Visit the
ATTO website,

www.attotech.com

, to download the latest drivers and flash bundle.

Hardware flash memory may need to be updated
as new versions become available or if the
factory-installed version becomes corrupt.

Updating flash in all operating systems

1 Download the most recent version of the

Configuration Tool from the ATTO website.

Refer to the ATTO Utilities Installation and
Operation Manual for additional information on
downloading and using the Configuration Tool.

2 Download the proper flash bundle (adapter

specific) from the ATTO website.

3 Extract these files to your desktop.

4 Install the Configuration Tool on your system.

5 Launch the Configuration Tool.

6 In the Device window, select the adapter that

needs to be updated.

7 In the Flash window, click on the Browse

button to find the flash bundle that you
previously downloaded to your desktop.

8 Click Update to update your flash ROM.

9 Reboot your system for the changes to take

effect.

Updating flash on a PC

You may update hardware flash on a PC using
BIOS utilities.

Note

BIOS utilities do not work on Itanium
systems. Use the ATTO Configuration Tool
to update flash on Itanium systems.

1 Download the latest driver software from the

ATTO Technology website.

2 The download is a self-extracting executable

that expands the driver software package. Run
the self-extracting executable and select a

package.

The expanded software package contains a
Miniport driver and may contain a StorPort
driver. The Celerity FC Windows Miniport driver
is in the base directory of the expanded
software package. The Celerity FC Windows
StorPort driver is in the StorPort subdirectory.

3 Navigate to the folder with the desired Celerity

FC driver.

4Run makedisk.bat and follow the instructions

for creating the floppy disk.

Note

The flash update must be loaded from a
floppy because CD-ROM drivers are not
loaded at this point in the system boot
process.

5 Reboot the PC.

6 During the reboot, an ATTO Technology

banner displays that the host adapter was
detected.

7 Enter Control-F when prompted to begin the

set-up utility within a few seconds after the

v ATTO Technology Inc. Celerity FC Host Adapters Installation and Operation Manual

Appendix E Safety, warranty, contacts

All ATTO host adapter products have been tested to meet applicable safety standards when operated in
proper electrical and thermal environments.

Safety

Please review the specifications for your specific host adapter before installing and operating it in any
computer system to ensure compatibility.

Installation

Before installing an ATTO host adapter product into your computer system, unplug the computer from
its electrical power source and allow adequate time for electrical discharge and the internal components
to cool down before removing the computer system cover. This will decrease the risk of personal injury
from electrical shock or touching the hot surface of an electrical component.

Once an ATTO host adapter is installed in a computer system, the computer cover must be reinstalled
properly before turning the computer system back on.

Operation

ATTO host adapters require adequate cooling to function properly. If you have any questions as to the
airflow provided by your computer system, please refer to your computer system manual or contact your
computer system manufacturer.

To facilitate proper air circulation, ATTO host adapters should never be operated in a computer system
without the cover installed or with an inoperable fan as this may cause safety or thermal problems which
could damage the ATTO host adapter and void the warranty.
