Features: Dual LAN 10G Network Card: Equipped with an Intel X540 controller, it provides dual LAN 10 Gbps for extremely high speeds, ensuring stable internet access and local data transfer, effectively preventing packet loss and making the server more stable. Network Interface: Two independent Ethernet interfaces for 10GBASE-T, 1000BASE-T, 100BASE-TX applications (IEEE 802.3an, 802.3, 802.3u, and 802.3ab), supporting Windows/Windows Server/Linux/Vmware/ESX. PCIe to 10Gbe RJ45: This 10G BASE-T PCIe network adapter converts PCIe slots (X8/16) into 10G RJ-45 Ethernet ports. Note: Only for PCIe slots, not for PCI slots. Adaptability and Heat Dissipation: Comes with standard and slim brackets for various applications like desktops, workstations, servers, and mini-tower computers. Excellent heat dissipation performance quickly reduces temperature and maintains network transmission stability.
