The Gigabit PCI Express Network Card is a high-performance network adapter. It supports the PCI Express bus architecture, which provides faster throughput than the current 32- & 64-bit PCI bus architectures. & there is no need to switch to fiber optic cable — the INTELLINET NETWORK SOLUTIONS Gigabit PCI Express Network Card means that you can run Gigabit speeds over your existing copper wire network cable. Faster Throughput The PCI Express host interface supports throughput rates of up to 2 Gbps when running in full duplex mode, ideal for resource-intensive CAD/CAM, client-server database, multimedia, pre-press, advertising graphics, server & mission-critical applications. Auto-Negotiation The Gigabit PCI Express Network Card will automatically detect the network speed that the LAN switch port is set to & run at the same speed. The card supports 10 Base-T Ethernet, 100 Base-TX Fast Ethernet & 1000 Base-T Gigabit Ethernet. Full Duplex When running in full duplex mode, the Gigabit PCI Express Network Card provides the following throughput rates: 20 Mbps (10 Base-T Ethernet), 200 Mbps (100 Base-TX Fast Ethernet) & 2 Gbps (1000 Base-T Gigabit Ethernet). Built-In Diagnostics The Gigabit PCI Express Network Card comes standard with crossover detection & auto correction capabilities that make installation & maintenance a snap. Supports Gigabit speeds over existing network cable Does not require fiber optic cabling to run Gigabit speeds PCI Express 1.0a bus interface fits 1, 4, 8 & 16X PCI-E slots Single PCI Express lane (x 1) 2.5 Gbps interface Full duplex flow control (IEEE 802.3x) Supports jumbo frames up to 9 k B Full duplex speeds (20 Mbps, 200 Mbps, 2000 Mbps) Wake-On-LAN (WOL) support Supports the most popular operating systems: Windows XP, Vista & Windows 7
