AT-2971SX/LC Gigabit Ethernet PCI Extended Server Interface Card

AT-2971SX/LC

PCI-x 64-bit fiber Gigabit interface card

High Performance

Ahigh performance interface card with a 32-bit
or 64-bit (33/66/1000/133 Mhz) bus,line speed
and jumbo frames support,Allied Telesis’
AT-2971SX/LC supports the calculation of TCP,
UDP and IP checksums through the hardware
platformwithout time loss bythe MAC
controller for both transmission and receiving
paths—a capability that leads to improvements
on overall system performance.Toreduce the
load on the CPU,Allied Telesis’AT-2971SX/LC
uses interrupt moderation to group the huge
amounts of interrupts caused by small packets
transferred at Gigabit speed,enabling the
handling of several data packets per interrupt.

High Reliability

The AT-2971SX/LC Gigabit Ethernet interface
card comes with a variety of reliability features
that maintain the longest-possible connection
through link aggregation,redundant switch
failover and PCI hot plug.The on-board sensors
and driver functions monitor the health of
interface cards and their ports, enabling
proactive network management.

Comprehensive Software Support

The AT-2971SX/LC interface cards feature a
set of software programs that assist you with
your network set-up and configuration.The
offline user diagnostic program provides system
administratorsand engineerswith a tool to
analyze Network Interface Cards and check
specific data.The network control program for
Windows 2K,Windows XP and Windows Vista
Server 2003 allows you to easily control and
configure all your AT-2971SX/LC interface
cards.
