Key Features

  • "High-Performance Chip and Operation Modes",Equipped with the original Intel I226-V chip, this network card offers outstanding performance. It supports both full-duplex and half-du 工 operation and can run at speeds of 10M/100M/1000M/2.5Gbps, providing flexible and efficient network connectivity options.
  • "Resource Optimization and Stable Operation",The card incorporates offload acceleration processing, which helps relieve the CPU from resource occupation. Moreover, with a larger heat sink, it effectively addresses heat dissipation issues in poor thermal environments, ensuring the long-term stable operation of the adapter card.
  • "Adaptive Port Speeds and Versatile Support",Its ports support adaptive rates for full-duplex and half-duplex modes, ranging from 10M to 2.5Gbps. It is applicable to various network communications with 2.5G access and offers support for functions like (PXE) VL aggregation, Hi-Spider Router (assuming it refers to a router software), flow control, software routers, and industrial switches.
  • "Compatibility and Connector Design",The PCI-E X1 gold-plated contacts of the network card are compatible with multiple types of slots. The gold plating prevents surface oxidation, enhancing contact performance and electrical conductivity, which in turn guarantees its performance and extends its service life.
  • "PCI-E Bus and Cabling Types",It operates on the PCI-E bus, conforming to PCIe 3.1 (5 GT/s) x1 and being compatible with x4, x8, and x16 interfaces. In terms of cabling, it is suitable for CAT5e, CAT6, and CAT6A cables, providing flexibility for network infrastructure setup.
