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® 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.
