(1) This device must not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired operation.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void
the user’s authority to operate this equipment.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users must
follow the specific operating instructions for satisfying RF exposure compliance.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
IEEE802.11b or 802.11g operation of this product in the U.S.A. is firmware-limited to channels 1 through 11.

Chapter 1
Introducing the AT-2973SX, AT-2973T, and AT-2973T/4 Adapters
This chapter provides an introduction to the Allied Telesis AT-2973SX,
AT-2973T, and AT-2973T/4 NetExtreme II Family Adapters and discusses
the following topics:
“Functional Descriptions” on page 16
“Features” on page 22

Chapter 1: Introducing the AT-2973SX, AT-2973T, and AT-2973T/4 Adapters
Functional Descriptions
The AT-2973SX, AT-2973T, and AT-2973T/4 Broadcom NetXtreme II
adapters are a new class of Gigabit Ethernet (GbE) converged network
interface controller (C-NIC) that can simultaneously perform accelerated
data networking and storage networking on a standard Ethernet network.
The C-NIC offers acceleration for all popular protocols used in the data
center, such as:
TCP Offload Engine (TOE) for accelerating TCP
Internet Small Computer Systems Interface (iSCSI) offload for
accelerating network storage access featuring centralized boot
functionality (iSCSI boot)
Enterprise networks that use multiple protocols and multiple network
fabrics benefit from the C-NICs ability to combine data communications,
storage, and clustering over a single Ethernet fabric by boosting server
CPU processing performance and memory utilization while alleviating I/O
bottlenecks.
The AT-2973SX adapter is set to a speed of 1000 Mbps in full duplex
mode automatically. You cannot change the speed or duplex mode of this
adapter.
The AT-2973T and AT-2973T/4 adapters include a 10/100/1000-Mbps
Ethernet MAC with both half-duplex and full-duplex capability and a 10/
100/1000-Mbps PHY. The transceiver is fully compatible with the IEEE
802.3 standard for auto-negotiation of speed.
As part of the company’s green range, all of three adapters are
engineered to reduce power consumption. They incorporate centralized
power management features that automatically place idle circuitry into a
lower power mode to save energy.
The following sections provide functional descriptions of the AT-2973SX,
AT-2973T, and AT-2973T/4 adapters:

AT-2973SX
Adapter
The AT-2973SX adapter connects a PCI-E compliant server or workstation
to a Gigabit Ethernet network using fiber optic cabling and a connector that
meets 62.5/125 µm or 50/125 µm multimode specifications. This adapter
operates at speeds of 1000 Mbps in full-duplex mode.
The AT-2973SX adapter is show in Figure 1.

AT-2973SX Adapter Physical Description
The faceplate on the AT-2973SX adapter provides two fiber optic
connectors for attaching the adapter to a compatible link partner. See
Figure 2 for an illustration of the adapter’s faceplate.
The AT-2973SX adapter has two fiber ports and two LEDs per port, as
shown in Figure 2 and described in Table 1 on page 18. The state of the

The TCP/IP protocol suite is used to provide transport services for a wide
range of applications for the Internet, LAN, and for file transfer. The TCP
protocol is specifically designed to insure that data packets are delivered
error free and in the correct sequence from an application running a one
computer to the receiving application. The TCP protocol suite historically
has run on the host CPU, but with higher data rates, this consumes a very
high percentage of its resources while leaving little resources for the
applications. With the use of the Broadcom NetXtreme II adapter and the
TCP Offload Engine feature, the TCP/IP processing can be moved to
hardware, freeing the CPU for application processing and other higher
priority tasks
.
The TCP/IP protocol suite is used to provide transport services for a wide
range of applications for the Internet, LAN, and for file transfer. Without the
TCP Offload Engine, the TCP/IP protocol suite runs on the host CPU,
consuming a very high percentage of its resources and leaving little
resources for the applications. With the use of the Broadcom NetXtreme II

adapter, the TCP/IP processing can be moved to hardware, freeing the
CPU for more important tasks such as application processing.
The Broadcom NetXtreme II adapter's TOE functionality allows
simultaneous operation of up to 1024 fully offloaded TCP connections for
1-Gbps network adapters. The TOE support on the adapter significantly
reduces the host CPU utilization while preserving the implementation of
the operating system stack.
Internet Small
Computer
Systems Interface
(iSCSI)
Power
Management
The IETF has standardized the Internet Small Computer Systems
Interface (iSCSI). SCSI is a popular protocol that enables systems to
communicate with storage devices, using block-level transfer (that is,
address data stored on a storage device that is not a whole file). In
addition, iSCSI maps the SCSI request and response application
protocols and its standardized command set over TCP/IP networks.
As iSCSI utilizes TCP as its sole transport protocol, it greatly benefits from
hardware acceleration of the TCP processing (that is, use of a TOE).
However, iSCSI as a Layer 5 protocol has additional mechanisms beyond
the TCP layer. iSCSI processing can also be offloaded, thereby reducing
CPU utilization even further.
The Broadcom NetXtreme II adapter targets best-system performance,
maintains system flexibility to changes, and supports current and future
OS convergence and integration. Therefore, the adapter's iSCSI offload
architecture is unique as evident by the split between hardware and host
processing.
When the system is down and waiting for a wake-up signal, the adapter
speed connection may be at 10 Mbps or 100 Mbps. However, it can return
to 1000 Mbps when the system is up and running if it is connected to a
1000 Mbps capable switch. For this reason, connect systems that use the
Wake on LAN (WOL) feature to a switch capable of both 1000 and 10/100
Mbps speeds.
Wake on LAN
(WOL) Feature
24
The WOL feature sets the speed at which the network adapter connects to
the network while the adapter is in Wake on LAN (WOL) mode which is
enabled automatically. The default speed for WOL mode is 100 Mb. An
adapter can negotiate speeds between 10 Mb and 100 Mb. You cannot
configure this feature because it is enabled automatically.
The WOL feature is supported on the AT-2973T and AT-2973T/4
adapters. It is not supported on the AT-2973SX adapter. For more
information, see “Limitations” on page 66.

For specific systems, see your system documentation for
information about support of the WOL feature.

The adapter driver intelligently adjusts host interrupt frequency based on
traffic conditions to increase overall application throughput. When traffic is
light, the adapter driver interrupts the host for each received packet,
minimizing latency. When traffic is heavy, the adapter issues one host
interrupt for multiple, back-to-back incoming packets, preserving host CPU
cycles.
The core control for Broadcom NetXtreme II adapters resides in a tightly
integrated, high-performance ASIC. The ASIC includes a RISC processor.
This functionality provides the flexibility to add new features to the card
and adapts it to future network requirements through software downloads.
This functionality also enables the adapter drivers to exploit the built-in
host offload functions on the adapter as host operating systems are
enhanced to take advantage of these functions.
The Broadcom NetXtreme II adapter has software support for the following
operating systems:
Microsoft Windows Server 2003 (32-bit and 64-bit extended)
Microsoft Windows Server 2008 (32-bit and 64-bit extended)
Microsoft Windows Server 2008 R2 (32-bit and 64-bit extended)
Microsoft Windows Vista (32-bit and 64-bit extended)
Microsoft Windows 7 (32-bit and 64-bit extended)

Reviewing the Contents of Your Shipment
The following items are included with your adapter:
Antistatic bag (used for protecting the adapter when stored or
shipped). Keep the adapter in its packaging until ready for installation.
Low-profile bracket (The low-profile bracket is not included with the
AT-2973T/4 adapter.)
Standard bracket
Inform your network supplier of any missing or damaged items. If you
need to return the adapter, you must pack it in the original (or equivalent)
packing material or the warranty will be voided. See “Returning Products”
on page 14.
