The Cisco SD2005 5-Port Gigabit Switch part of the Cisco Small Business Series, provides nonblocking, wire-speed switching for your 10-, 100-, and 1000-megabit network clients. Use this switch to replace your current workgroup hub or Fast Ethernet switch, to upgrade your high-requirement workstations to full Gigabit speeds as necessary, while continuing to service other clients at their current speeds. Or build your network from the ground up, with appropriate link speeds for each user's requirements. Either way, it's perfect for graphics, multimedia, and other applications that have to move large files across the network quickly.
With the Cisco SD2005, you can upgrade your existing 10/100 Ethernet network to Gigabit speed without any additional equipment. All ports have automatic medium dependent interface (MDI) and MDI crossover (MDI-X) detection, so you don't have to worry about the cable type. Each port also independently and automatically negotiates for best speed and whether to run in half- or full-duplex mode. Address Learning and Aging is supported, as well as 802.3x flow control with head-of-line blocking prevention to optimize your network performance. Fast store-and-forward switching prevents damaged packets from being passed on to the network.
