PCIe x4 Quad-port Gigabit PoE+ Ethernet Network Adapter (Intel I211 Chip Based)



Key Features

  • Developed on the basis of intel chip designed and produced with Intel I211;
  • A PCI Express v2.1 x4 quad-port copper gigabit ethernet network adapter;
  • It has the advantages of low cost and convenient deployment in data center deployment;
  • It is of great significance for breaking the monopoly of certain enterprises and ensuring information security.


LRES2048PT-POE is a Quad-port copper gigabit ethernet PCI Express v2.1 x4 PoE+ ethernet frame capture card independently developed by Shenzhen Lianrui Electronics Co., Ltd. based on the Intel I211AT main control chip solution. It is also compatible with PCIe x8, x16 aisle. This server adapter card is mainly designed to be used in industrial field visual inspection servers and equipment, visual field clients, fast mobile Ethernet data transmission equipment, etc. It is also suitable for ordinary servers.

The adapter has integrated hardware acceleration and is capable of performing TCP/UDP/IP checksum offload and TCP segmentation tasks. Host processing technology can offload accelerators, freeing up CPU resources to free up more CPU resources to process other applications.

LR-LINK has made a unique design for this adapter:
1. The PoE+ output power consumption is up to 30W/per power, and an external 4-Pin power supply supply interface is provided.
2. Adapt to the power consumption output required by external devices: Class 0, Class 1, Class 2, Class 3, Class 4;
3. The adapter card adopts a wider RJ45 spacing design;
4. The interface designed for industrial-grade cable access effectively solves the problem of compact network ports in industrial places, and is compatible with ordinary cable access;
5. The larger heat sink can effectively solve the heat dissipation problem of the adapter in the case of poor heat dissipation environment, and effectively ensure the long-term stable operation of the adapter card;
6. The thickened immersion gold RJ5 connector is carefully selected to ensure more solid and reliable connectivity;
7. The design of four 8-Pin RJ45s can better save the precious PCIe slot resources.
