The SMC8508T is a 8-port 10/100/1000 Gigabit switch that provides non-blocking, wire-speed switching for your 10, 100, and 1000 megabit network clients. With the SMC8508T, you can connect your existing 10/100 Ethernet network to a Gigabit server backbone without any additional equipment. You can replace your current workgroup hub or switch with the SMC8508T and instantly upgrade your high-requirement workstations to full Gigabit speeds, while continuing to service other clients at their current speeds. Or you can build your network from the ground up, with appropriate link speeds for each user's requirements. Either way, the SMC8508T, and its jumbo frame support, is perfect for graphics, multimedia, and other applications that require you to move large files across the network quickly. All ports have automatic MDI/MDI-X crossover detection, so you don't have to worry about cable types. Each port independently and automatically negotiates for best speed and whether to run in half- or full-duplex mode. Limited Life Time Warranty. 24/7 Technical Support 1-800-SMC-4YOU.
