The Intel X540 series products are designed for existing networks. They operate alongside traditional Gigabit Ethernet (GbE) switches and Cat 6A cables. Installing the Intel X540 adapter into servers provides automatic negotiation between 1GbE and 10GbE,offering backward compatibility for smooth transitions and easy migration to 10GbE,meeting the needs of most customers. 10GBase-T switches can be added at any time,when time and budget allow,to experience the full benefits of 10GbE. The Intel Ethernet Converged Network Adapter X540 is a cost-effective way to deploy 10GbE in today's data centers. The Intel X540 supports low-cost Category 6 and 6A cables,which may already exist in data center wiring. One method Intel employs to lower costs and power consumption is integrating components into single-chip solutions,which they excel at. With the Intel X540 controller,MAC,and PHY are integrated into a single-chip solution,resulting in lower costs and power consumption,making 10GBase-T ready for extensive deployment. 10GBase-T is an option for every rack and tower server in the data center. The era of waiting for low-cost 10GbE copper cable solutions to deploy 10GbE widely across data center is over. The Intel X540 adapter offers highly cost-effective 10GbE network performance for bandwidth-intensive applications and economical RJ-45 connections with distances of up to 100 meters. •Dual-port 10GBase-T network adapter supporting 10G,1G,and 100Mbps network speeds •Capable of delivering up to 10Gbps over 100-meter Cat 6a cables,and 1Gbps/100Mbps over 100-meter Cat 5e/Cat 6 cables •Backward compatible with 1000Base-T and 100Base-TX networks •PCI Express Gen2 x8 host bus interface •Supports PXE network booting •Virtualization (Microsoft Hyper-V®) and iSCSI support •Jumbo frame support up to 15.5 kb •Quality of Service (QoS) support •Checksum offload (IP,TCP,UDP) and large send offload support •Compatible with both Microsoft and Linux platforms •Configurable standard profile brackets,including low-profile/half-height brackets •Compatible with both Microsoft and Linux platforms Specifications: •Bus Type: PCI Express 2.1 (8.0 GT/s) •Bus Width: x8 lane PCI Express,operates in x8 and x16 slots •Card Type: Standard/Low Profile •Chipset ID: Intel - X540-AT2 •Industry Standards: IEEE 802.3u 100BASE-TX,IEEE 802.3ab 1000BASE-T,IEEE 802.3an 10GBASET-T,IEEE 802.1Q VLANs,IEEE 802.3x Flow Control,IEEE 802.1p Priority Queuing,IEEE 802.3az EEE •Interface: 2 x RJ45 •Power Consumption: 10Gbps-12.5W •System and Cable Requirements: Computer with PCI Express support,with an available PCI Express x8 slot Gen 2.0 or higher (x16) •Operating System Compatibility: Windows® 7,8; Windows Server® 2008 R2,2012,2016,2019; Linux 2.6.x to 4.x •LED Indicators: 1 - Link Speed LED (Green: 10Gbps; Amber: 1Gbps; Off: 100Mbps) 1 - Link/Activity (Green) •Humidity: 20~80% RH •Operating Temperature: 5°C to 55°C (41°F to 131°F) •Storage Temperature: -25°C to 70°C (-13°F to 158°F) Package included: •1 x Network Card
