PCIe 3.1 x4 Network Controller — Quad I226 (SRKTU) Chips, PLX Bridge, 4× RJ45 2.5G (10/100/1000/2500 Mbps)

High-performance PCIe 3.1 x4 network adapter with four RJ45 ports, each supporting multi-rate Ethernet at 10/100/1000/2500 Mbps (up to 2.5Gbps). The card uses four I226 (SRKTU) chips linked via a PLX bridge to deliver stable, efficient data transfer for desktops and servers. Compliant with IEEE 802.3 for Ethernet to 2.5Gb/s, 802.3x and 802.3z flow control, and 802.3az energy-efficient Ethernet for broad compatibility and improved power use. Networking features include Wake-On-Lan, UDP and IPv4 checksum offloading, and support for jumbo frames up to 9.5KB. Time-sensitive and precision networking are supported through IEEE 1588 protocol and 802.1AS. The card ships with both high- and low-profile brackets for installation in different chassis types and supports automatic MDI/MDI-X crossover to eliminate the need for crossover cables. Compatible with PCIe x4, x8, and x16 slots, this quad-port solution is well suited to office PCs and servers requiring robust 1G and 2.5G connectivity. Supports operating systems from ME through 11 and a range of Linux distributions.
