Introduction to the AT-29xxSX Series Gigabit Ethernet Network Adapters
16
Functional Description
The AT-29xx Series Gigabit Ethernet network adapters target the
increased congestion experienced at the backbone and server in today’s
networks and it provides 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. This adapter
operates at 1000 Mbps full-duplex mode only.
The AT-29xxSX Series of Gigabit Ethernet adapters includes the following
models:
ˆ AT-2916SX
ˆ AT-2931SX
ˆ AT-2972SX
ˆ AT-2972SX/2
The AT-2916SX adapter is a 33/66Mhz 32-bit interface (PCI) card and is
available in two versions:
ˆ AT-2916SX/SC adapter
ˆ AT-2916SX/LC adapter
The AT-2931SX adapter is a 33/66/133Mhz 32/64-bit interface (PCI-X)
card and is available in two versions:
ˆ AT-2931SX/SC adapter
ˆ AT-2931SX/LC adapter
The AT-2972SX, AT-2972SX/2, and AT-2972T/2 adapters are PCI
Express 4-channel devices. The AT-2972SX has one port, and the
AT-2972SX/2 has two ports. All ports have LC connectors. The
AT-2972T/2 has two gigabit copper ports.
The adapter versions differ only in their PCI connector type. The SC
version adapters have an SC connector, and the LC version adapters
have an LC connector. The LEDs and software drivers are identical for all
adapter models and versions.
