The LR-Link LREC9812BT is a dual-port network interface card designed to bring high-speed connectivity to servers and workstations. Built around the Intel X550 controller, it connects via a PCIe v3.0 x4 interface with a bandwidth of 8.0 GT/s, allowing you to achieve transfer rates up to 10 Gbps through its two RJ45 copper ports. This adapter is highly versatile in its networking capabilities, supporting 10GBASE-T, 5GbE, 2.5GbE, and 1000BASE-T speeds. You can run cables up to 100 meters using Cat6A, while Cat5e is supported for NBASE-T connections. To reduce the load on your system's CPU, the card handles TCP, UDP, and IP checksum offloading as well as TCP segmentation directly in hardware. For those managing virtualized environments, the integrated support for SR-IOV and VMDq helps optimize traffic distribution. The card also includes PXE boot capabilities for network-based startup and a simple LED indicator to monitor connection status. Measuring 137 x 69 x 1.6 mm, it fits easily into standard slots and operates reliably within a temperature range of 0 °C to 50 °C.
