Features:Dual Lan 10G Network Card: Adopting Intel X540 Controller, it provides up to Dual Lan 10 Gbps of extreme speed to ensure the stability of Internet access and local data transmission, effectively preventing packet loss and making the server more stable.Network Interfaces: Two independent Ethernet interfaces for 10GBASE-T, 1000BASE-T, 100BASE-TX applicationgs (IEEE 802.3an, 802.3,802.3u, and 802.3ab), supports 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 Compatible for PCIe ports, not for PCI slots.Adaptability and heat dissipation: Comes with standard brackets and slim brackets for different applications such as desktops, workstations, servers, and mini-tower computers. Excellent heat dissipation performance can quickly reduce the temperature and keep the stability of network transmission.Specifications:Lan Transmission Rate: 10000M EthernetApplicable Network Type: 10-Gigabit EthernetPackage: YesModel Number: 10G Double Port Ethernet CardApplication: DesktopInterface Type: PCI ExpressAdapter Socket: PCI-EKind: ExternalTransmission Rate: 10-Gigabit EthernetType: WirelessFeature 1: 10Gbps Port Ethernet Network CardFeature 2: PCIE-X8 X16Feature 3: PCIE-X8 Network Extend AdapterFeature 4: Dual Copper RJ45 10Gbps Port Ethernet Network CardSystems:Server 2003 / Server 2008 / Vista / Win 7 / Win 8 / Win 10 32-64bitWindows Server 2003 / 2008 / 2008 R2 / 2012 / 2012 R2 /2016 R2FreeBSD, Linux Stable Kernel, VMware ESX/ESXiPackage includes:X540-T2 Network Card x 1Low profile bracket x 1
