Add two Ethernet ports to a server or workstation through one PCI Express slot, with support for five network speeds: 10G/5G/2.5G/1G/100 Mbps. This dual-port network card offers versatile & cost-efficient network connectivity, by increasing the available network bandwidth without having to replace your existing cabling infrastructure. The 5-speed network card lets you add two 10G/NBASE-T RJ45 ports to your server or desktop computer & access your network at multiple speeds: 10G, 5G, 2.5G, 1G, & 100 Mbps. Compatible with a broad range of operating systems, this versatile dual-port NIC is ideal for many business applications that require upgrades to servers or workstations. Fully compliant with 10GBASE-T & NBASE-T specifications, the network card is a cost-effective way to enhance your server or computer capabilities by adding two powerful 10-Gigabit Ethernet ports. (10G network speeds require Cat 6a cable. All other speeds require Cat 5e cable.) The network card supports advanced NBASE-T technology, compatible with the latest multi-gigabit Ethernet switches & routers, such as new Cisco campus switches (including Catalyst 4500E, 3850 & 3560-CX). The card enables you to connect to NBASE-T based equipment at network speeds of 2.5 Gbps or 5 Gbps, over your existing Cat 5e infrastructure, without having to upgrade to more expensive Cat 6a. NBASE-T technology accelerates the speed of twisted pair Cat 5e copper cabling over a distance of up to 100 meters. The Ethernet network card also supports 10 Gbps network speeds if using Cat 6a cabling, & 1 Gbps network speeds if using Cat 5e (or better) cabling. The Ethernet ports are based on the Intel X550 chipset, designed to deliver the power, performance, & enhanced capabilities you need for reliable network connections to your server or computer. The network card also supports advanced features including 9K jumbo frames & 802.1q VLAN tagging. With a dual-profile design, the PCI Express network card installs e
