Powerful, With Gold-Plated Interface Shielding, Which Can Effectively Prevent Interference And Make Data Transmission Smoother. Each Network Card Has An Address, And Ip Can Be Set Independently. It Supports Multi-Card Aggregation Routers, Ros And Network Card Startup. Stable Performance, Using The 82574L Powerful Core, Suitable For Most Common Servers, Powerful Functions Provide Ethernet Ports, Improve Broadband, Enhance Scalability, And Reliability. Immersion Gold Technology, The Gold Finger Adopts Immersion Gold Technology, The Data Is Not Distorted, And The Transmission Is More Stable. The Thickened Electro-Gold Is Harder Than Ordinary Electro-Gold And Has More Stable Wear Resistance, And The Data Is Less Prone To Packet Loss And Distortion. Easy To Install And Use.
