Cisco SR2016 16-Port 10/100/1000 Gigabit Switch Cisco Small Business Unmanaged Switches Wire-Speed Switching and Cisco Reliability in a 16-Port Gigabit Switch Highlights ● Connect up to 16 network devices - PCs, printers, and servers - to share and transfer files and videos across your network ● High-speed conectivity to support bandwidth-intensive applications ● Works right out of the box with no software to configure ● Rack-mount installation Product Overview The Cisco(r) SR2016 16-Port 10/100/1000 Gigabit Switch (Figure 1) provides nonblocking, wirespeed 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 SR2016, 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. The rack-mount form factor integrates smoothly into your network infrastructure. Let the Cisco SR2016 16-Port 10/100/1000 Gigabit Switch kick your network into high gear.
