Introduction

The GEAPX4-PCIE8XG321 is Quad-Port 10GBASE-T/ 5GBASE-T/ 2.5GBASE-T/ 1000BASE-T/ 100BASE-TX/ 10BASE-Te Ethernet (POE+) to PCIe x8 Gen 3 Host Card.

The GEAPX4-PCIE8XG321 Ethernet controller combines a six-speed IEEE 802.3 compliant Media Access Controller (MAC) with a six-speed Ethernet transceiver, PCI Express bus controller, and embedded memory. With state-of-the-art DSP technology and mixed-mode signal technology, it offers high-speed transmission over CAT 6 or CAT 6a cables.

The GEAPX4-PCIE8XG321 Ethernet controller supports the PCI Express 3.0 bus interface for host communications with power management, and is compliant with the IEEE 802.3u specification for 10/100Mbps Ethernet and the IEEE 802.3ab specification for 1000Mbps Ethernet and the IEEE 802.3bz specification for 2.5/5Gbps Ethernet and the IEEE 802.3an specification for 10Gbps Ethernet.
The GEAPX4-PCIE8XG321 Ethernet controller is fully compliant with Microsoft NDIS5, NDIS6 (IPv4, IPv6, TCP, UDP) Checksum and Segmentation Task-offload (Large send and Giant send) features, and supports IEEE 802.1P Layer 2 priority encoding and IEEE 802.1Q Virtual bridged Local Area Network (VLAN) and IEEE 802.1ad Double VLAN. The above features contribute to lowering CPU utilization, especially benefiting performance when in operation on a network server.

This product is designed for high-speed 10G/PoE applications and is highly sensitive to environmental noise. To ensure optimal performance and minimize electromagnetic interference (EMI), we highly recommend using this product with shielded Category 6A (STP) or higher Ethernet cables.
