Dual-port PCIe x1 Gigabit Ethernet adapter with Intel 82576 controller for fault-tolerant connectivity.
When legacy servers lack available PCIe lanes, deploying redundant gigabit connectivity becomes a critical challenge for maintaining uptime. The LREC9212PT dual-port network adapter solves this by utilizing a single PCIe x1 slot to deliver reliable copper Ethernet access.
Based on the Intel 82576 controller, this card provides 1Gbps per port bandwidth with integrated TCP/UDP/IP checksum offload, freeing CPU resources for application processing. Its support for port teaming enables automatic failover, ensuring uninterrupted communication during hardware faults without manual intervention.
Ideal for workstations and multi-network deployments, the LREC9212PT offers excellent cost-performance compared to higher-lane alternatives. This PCIe x1 adapter ensures enterprise-grade reliability and OS compatibility for space-constrained systems requiring dual gigabit connections.
Based on Intel 82576 chip providing proven performance and broad OS compatibility for enterprise environments.
Operates in PCIe x1 slots while remaining compatible with x4, x8, and x16 channels for flexible deployment.
Supports port teaming to combine multiple ports, ensuring uninterrupted communication via automatic failover.
Integrated TCP/UDP/IP checksum offload and TCP segmentation frees host CPU resources for other applications.
Compatible with Windows, Linux, FreeBSD, and VMware ESX/ESXi for diverse server and workstation environments.
