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
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.
