PCIe Quad Port Gigabit Network Card 4 x Intel I210AT, ASM1812 PCIe Switch, 10/100/1000Mbps, Supports Link Aggregation, VLAN, PXE, for Server & Soft Router

Maximize your network connectivity with this PCIe Quad Port Gigabit Network Card. Powered by four Intel I210AT Gigabit Ethernet controllers and an ASMedia ASM1812 PCIe switch, this high-density adapter adds four independent 10/100/1000Mbps RJ45 ports from a single PCIe slot, making it the ideal solution for servers, soft routers, virtualization hosts, and industrial systems requiring reliable, high-performance wired networking.

Intel I210AT Enterprise-Grade Controllers

Each of the four ports is powered by its own Intel I210AT Gigabit Ethernet controller, delivering:

1. Low latency for real-time applications
2. Hardware offloads including TCP/IP checksum offload and segmentation offload
3. Energy Efficient Ethernet (IEEE 802.3az) for reduced power consumption
4. IEEE 1588 Precision Time Protocol for time-sensitive synchronization
5. Proven reliability for 24/7 operation

ASM1812 PCIe Switch Architecture

The ASMedia ASM1812 PCIe switch ensures efficient lane distribution from the host PCIe interface to the four independent I210AT controllers, providing:

1. Stable, consistent throughput across all ports
2. Reliable signal integrity for high-speed data transmission
3. Seamless integration with desktop and server motherboards

Quad Gigabit Connectivity

Each of the four RJ45 ports supports:

1. 10/100/1000Mbps auto-negotiation
2. Full-duplex and half-duplex operation
3. IEEE 802.3x flow control for reliable data transmission
4. Jumbo frame support for improved throughput
