PCIe X4 Dual Port Gigabit Ethernet NIC, 82576EB Chip 10/100/1000Mbps Dual RJ45 Server LAN Card with 8CM & 12CM Brackets

This PCIe X4 dual-port gigabit network card features industrial-grade 82576EB chip, delivering two separated 1G Ethernet channels to meet multi-network deployment demands of servers, storage NAS and workstations.

It supports link aggregation, fault tolerance and jumbo frames to lift total network throughput and prevent network disconnection risk during long-time data transmission. Built on PCIe X4 bus architecture, it ensures sufficient bandwidth to avoid bottlenecks under high concurrent data loads.

Two replaceable brackets (8CM low-profile & 12CM full-height) are included, matching standard ATX cases and slim small chassis for flexible installation. The card auto negotiates 10Mbps, 100Mbps and 1000Mbps network speeds to fit various switches and routers.

Optimized PCB layout reduces signal loss and electromagnetic interference, maintaining steady operation under 24/7 continuous working. Widely applicable to file servers, industrial control hosts and office multi-network devices as a high-performance wired expansion solution.
