The LR-Link LREC9712HT is a dual-port network adapter designed to provide stable and efficient Gigabit Ethernet connectivity for servers and workstations. Built around the reliable Intel I350 controller, this card features two RJ-45 ports that support transfer rates of 10/100/1000 Mbps in full-duplex mode, ensuring a consistent flow of data for demanding network tasks. It connects via a PCI Express x4 interface, which remains compatible with x8 and x16 slots for flexible installation in various motherboard configurations. To reduce the load on your system's CPU, the adapter handles hardware TCP/UDP/IP checksum offloading and TCP segmentation. It also supports advanced networking capabilities such as port aggregation for increased bandwidth, seamless failover for redundancy, and DPDK and virtualization support for modern virtualized environments. Measuring 22.36 x 14.75 x 2.89 cm and weighing 222 g, the card is designed to operate within a temperature range of 0 °C to 55 °C. It incorporates the IEEE 802.3az Energy Efficient Ethernet standard to lower power consumption during periods of low data activity, while integrated LED indicators provide quick visual confirmation of the connection status.
