Chapter 1: Overview
Functional Description
The AT-2900 Series Gigabit Ethernet Adapters target the increased
congestion experienced at the backbone and server in today’s networks.
These adapters provide a future upgrade path for high-end workstations
that require more bandwidth than Fast Ethernet can provide.
The adapter connects a PCI compliant server or workstation to a Gigabit
Ethernet network. The adapter incorporates a technology that transfers
data at a maximum rate of 2Gbps - 20 times the rate of Fast Ethernet
adapters. In addition, the adapters use fiber optic cabling and a connector
that meets 62.5/125um or 50/125um multimode specifications. These
adapters operate at 1000 Mbps full-duplex mode only.
The AT-2900SX Series of Gigabit Ethernet adapters includes the following
models:
AT-2916SX
AT-2931SX
AT-2972SX
The AT-2916 adapter is a 33/66Mhz 32-bit interface (PCI) card and is
available in three versions:
AT-2916SX/SC adapter
AT-2916SX/LC adapter
AT-2916LX10/LC adapter (suitable for long-haul fiber optic cables)
The AT-2931SX adapter is a 33/66/133Mhz 32/64-bit interface (PCI-X)
card and is available in two versions:
AT-2931SX/SC adapter
AT-2931SX/LC adapter
The AT-2972SX is a PCI Express 1-channel device.
The AT-2972LX10/LC adapter is suitable for long-haul fiber optic cables.
The AT-2972SX has one port. All ports have LC connectors.
The adapter versions differ only in their PCI connector type. The SC

Failover Teaming
Note
Note
AT-2900 Series Gigabit Ethernet Network Adapters Installation Guide
Failover Teaming provides redundant adapter operation in the event that a
network connection fails. When multiple Allied Telesis Gigabit Ethernet
adapters are installed in the same server, they can be paired into Teams.
Each team must have at least one adapter, but can support up to eight
adapters. The number of teams is limited by the number of adapters that
are installed.
If the primary adapter in a team is disconnected because of failure of the
adapter, cable, or switch port, the secondary team member becomes
active, redirecting both inbound and outbound traffic originally assigned to
the primary adapter. Sessions are maintained, causing no impact to the
user.
The AT-2900 Series adapters have advanced server features for teaming
and failover. For more information, see the Broadcom Advanced Control
Suite 3 User’s Guide which you can download from the Allied Telesis
website at www.alliedtelesis.com/support/software.
Allied Telesis recommends disabling STP when using the teaming
and fault tolerance features.
Failover Teaming is available with the Broadcom Advanced Control
Suite 3 (BACS 3) utility.

Caution
Figure 3. Inserting the Network Adapter Card
The connector dock in a 32-bit PCI slot is shorter than in a 64-bit PCI
slot. Although the AT-2931SX adapter is designed to fit in either slot
type, when installed in a 32-bit PCI slot, part of the adapter’s
connector edge remains undocked. This is part of normal operation.
When you install an AT-2931SX adapter in a 32-bit slot, the adapter
operates in 32-bit mode only.
Do not use excessive force when seating the card, because this may
damage the system or the adapter. If the card resists seating,
remove it from the system, realign it, and try again.
6. Secure the network adapter card to the chassis with a Phillips-head
