This dual-port network card offers versatile and 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 and access your network at multiple speeds: 10G 5G 2.5G 1G and 100Mbps.Cost-effective multimode network connectivityCompatible 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 and 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 Cat6a cable. All other speeds require Cat5e cable.)Connect to NBASE-T equipmentThe network card supports advanced NBASE-T technology compatible with the latest multi-gigabit Ethernet switches and routers such as new Cisco campus switches (including Catalyst 4500E 3850 and 3560-CX). The card enables you to connect to NBASE-T based equipment at network speeds of 2.5Gbps or 5Gbps over your existing Cat5e infrastructure without having to upgrade to more expensive Cat6a.NBASE-T technology accelerates the speed of twisted pair Cat5e copper cabling over a distance of up to 100 meters. The Ethernet network card also supports 10Gbps network speeds if using Cat6a cabling and 1Gbps network speeds if using Cat5e (or better) cabling.The Ethernet ports are based on the Intel X550 chipset designed to deliver the power performance and enhanced capabilities you need for reliable network connections to your server or computer. The network card also supports advanced features including 9K jumbo frames and 802.1q VLAN tagging.Easy installationWith a dual-profile design the PCI Express network card installs easily into a wide range of computer/server chassis regardless of form factor. The card comes equipped with a standard-profile bracket for installation in a full-sized chassis and includes a low-profile/half-height bracket for installation in small form-factor computers.The ST10GPEXNDPI dual-port network card is backed by a StarTech.com 2-year warranty and free lifetime technical support.
