Cisco Business 250 Series Smart Switches
The Cisco Business 250 Series is the next generation of affordable switches that combine powerful performance and reliability with a complete suite of the features you need for a solid business network. These switches provide flexible management options, comprehensive security capabilities and Layer 3 static routing features far beyond those of an unmanaged or consumer-grade switch, at a lower cost than for fully managed switches. When you need a reliable solution to share online resources and connect computers, phones, and wireless access points, Cisco Business 250 Series Switches provide the ideal solution at an affordable pricing point.
