Dual SFP Gigabit Server Adapter

This PCI Express x4 network card adds two 1 Gbps SFP ports to a server or workstation. It is built around the Intel I350 controller for reliable wired connectivity in multi-core environments. The bracket fits both low-profile and full-height chassis.

Suited for virtualised hosts needing extra fibre

It suits administrators expanding a virtualised host with additional Gigabit fibre uplinks. It is not for machines that only have PCI Express x1 slots available. It is not for deployments that require 10 Gbps or faster port speeds.

PCI Express 2.1 x4 electrical interface

The card runs on a PCI Express 2.1 x4 link at 5.0 GT/s and is compatible with x4, x8 and x16 slots. This single interface detail decides whether the adapter will negotiate full bandwidth in the target system.

Questions about this item

Does my motherboard need a PCI Express x4 slot for this LREC9712HF-2SFP card?

The card uses a PCI Express v2.1 x4 interface and is compatible with x4, x8 and x16 slots, including Low Profile and Full Height brackets.

Will the Intel I350 based adapter work with my older Windows Server 2008 R2 installation?

Yes, the driver stack supports Windows Server 2008 R2 alongside Windows 7, 8, 8.1 and Server 2012 R2.

How can I verify both SFP ports are passing traffic after installation?

Check link LEDs on each port, confirm 1000 Mbps speed in the OS network panel, and run a ping or iperf test through each SFP transceiver.
