Dual-port Gigabit NIC for servers and workstations

This PCI Express x1 card adds two independent RJ45 ports to a desktop, rack-mount server or slim appliance. It is aimed at administrators who need separate management and data links or link-aggregation without occupying a larger slot. The low-profile bracket fits 1U chassis while the included full-height bracket covers standard towers.

Intel 82571 controller with PCIe 1.0a x1 interface

The card uses the original Intel 82571 controller connected through a PCIe 1.0a lane running at 2.5 GT/s. This single specification determines compatibility: the host must provide a PCIe x1, x4, x8 or x16 slot that negotiates at 1.0a speed. No other controller or bus variant is present.

Passive cooling with minimal power draw

The board relies on passive heatsinks and the system’s airflow; no fan is fitted so acoustic output is zero. Power consumption stays within the PCIe x1 slot envelope, requiring no auxiliary connector. Operating temperature range follows the Intel 82571 specification for typical server and office environments.

Questions about this item

Will the Intel 82571 controller actually deliver 1000 megabits per second on each port when installed?

Each RJ45 port runs at 10/100/1000 megabits per second, and the Intel 82571 controller handles both simultaneously with QoS, TCP checksum offload and jumbo frame support.

Does the PCIe 1.0 x1 link limit the combined throughput of the two gigabit ports?

The card uses a PCI Express 1.0 x1 interface at 2.5 GT/s, which is the native connection for the Intel 82571 and supports iSCSI, PXE and VLAN functions.

Can this card fit in a slim server that only accepts low-profile brackets?

Yes, the package includes both a low-profile bracket and a full-height bracket for standard or slim chassis mounting.
