The Ethernet Server Adapter compatible with Intel I210 is specifically designed for high-performance network devices such as servers, with features such as low power consumption, high performance, and stability. It is suitable for various operating systems and can be used in a wide range of applications. Data Rate Per Port: 1.25Gbps/1Gbps/100 Mbps/10Mbps. 1.25g RJ45-Port network card with VLAN tagging transmission rate can reach up to 1.25Gbps,and it also supports 10/100/1000Mbps speed and is backward compatible with these transmission rates. It can automatically adapt to different speed network environments, providing efficient, stable, and reliable network connectivity. Supported Operating Systems: Widows 7/8/10/11, Windows Server 2008 R2/2012 R2/2016/2019/2022, VMware ESX/Esxi 5/6/7, FreeBSD 7/8/9/10/11/12/13 ,Linux kernel 2.4.x, 2.6.x, 3.x, 4.x, and 5.x (including most distributions such as Ubuntu, CentOS, and Debian) , SUES 11/12/15, etc. Interface: PCI-E 2.1 x1/x4/x8/16 slot Port: 1 x RJ45 Cable Type: Cat5e/Cat6/Cat6A or higher cable is recommended Support: DCB,SR-IOV, RSS, TCP/IP, WoL, PXE and ISCSI,PCoE and VMDq Support IEEE 802.3az EEE, IEEE 1588 PTP,IEEE 802.1Q for increased efficiency and reduced power. The difference between RJ45 and SFP Port for I210 NIC The RJ45 interface is typically used in Ethernet LANs and Internet access scenarios. Its advantages include easy installation, configuration, and maintenance, as well as wide compatibility with most networking devices such as switches, routers, and computers. The SFP interface is suitable for long-distance transmission, high-speed data transfer or special network environments (such as fiber optic networks). The SFP interface can use various types of optical modules, supporting different types of fiber and transmission distances. Package Contents: 1 x 1.25GbE Ethernet Server with Full height Bracket 1 x Low-profile Bracket ## Features - Compatible with I210-AT, the networking adapter transfer rate can reach up to 1250Mbps, is a flexible adapter for your networking requirements. - Port: 1x Copper RJ45. Can be connected with Category-6A/Category-7 for meeting the demands of data center environments. - Interface Type: PCIe v2.1(2.5GT/s)x1 Lane,also compatible with x4, x8, x16 Slot.
