Product Overview
The Cisco

SD2008 8-Port 10/100/1000 Gigabit Switch (Figure 1) provides nonblocking, wire-
speed switching for your 10-, 100-, and 1000 megabit (Mb) network clients. Use this switch to
replace your current workgroup hub or switch, and you can 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 SD2008, you can connect your existing 10/100 Ethernet network to a Gigabit server
backbone without any additional equipment. All ports have automatic medium dependent interface
(MDI) and MDI crossover (MDI-X) cable detection, so you don’t have to worry about the cable type.
Each port independently and automatically negotiates for best speed and determines whether to
run in half- or full-duplex mode. Address Learning and Aging are supported, as well as 802.3x flow
control with head-of-line blocking prevention to keep your high-speed clients from bogging down in
lower-speed traffic. Fast store-and-forward switching prevents damaged packets from being
passed on to the network.
