Cisco Small Business SF250-48 switch – 48 ports – Managed – rack-mountable
In today’s hyperconnected world, reliable access to network resources is critical to all businesses. However, you also need to invest wisely to stay competitive, knowing how to separate the essential from the extraneous and get the most value for your dollar. For investment in network infrastructure, building a solid foundation for your business is essential, but it doesn’t mean you need the most advanced feature set on the market.
With Cisco 250 Series Smart Switches, you can achieve business-class network performance and security without paying for advanced network management features that you will not use. When you need a reliable solution to share online resources and connect computers, phones, and wireless access points, but low cost is a top priority, Cisco 250 Series Smart Switches provide the ideal solution.
The Cisco 250 Series is the next generation of affordable smart switches that combine powerful network performance and reliability with the essential network management features you need for a solid business network. These expandable Fast Ethernet or Gigabit Ethernet switches provide basic management, security, and quality-of-service (QoS) features beyond those of an unmanaged or consumer-grade switch, at a lower cost than managed switches. And with an easy-to-use web user interface, Auto Smartports, and flexible Power over Ethernet (PoE) Plus capability, you can deploy and configure a complete business network in minutes.
