The key to succeeding in today’s competitive business environment is investing resources wisely – knowing how to separate the essential from the extraneous and get the most value for your dollar. As the backbone of your business and productivity applications, the small business network clearly falls into the “essential” category. But that doesn’t mean you need the most advanced feature set on the market.
With Cisco® 200 Series Smart Switches, you can achieve business-class network security and performance without paying for advanced network management features that you will not need. When you need a reliable solution to share network resources and connect computers, printers, and servers, but low cost is a top priority, Cisco 200 Series Smart Switches provide the ideal solution.
Cisco 200 Series Smart Switches
The Cisco 200 Series is a series 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, Cisco Discovery Protocol, and Cisco Smartports, you can deploy and configure a rock-solid business network in minutes.
Business Applications
Whether you need basic high-speed connectivity for your computers and servers or a comprehensive voice, data, and wireless technology solution, Cisco 200 Series switches can meet your business needs. Possible deployment scenarios include:
- High-speed desktop connectivity. Cisco 200 Series switches can quickly and securely connect employees working in small offices with one another and with all of the servers, printers, and other devices they use. High performance and reliable connectivity help speed file transfers and data processing, improve network uptime, and keep your employees connected and productive.
- Highly secure wireless connectivity. Cisco 200 Series switches work with Cisco and third-party wireless solutions to extend the reach of your network. Employees can work productively from conference rooms and common areas, collaborate in any office, and access business applications from wherever they are. With their security features, Power over Ethernet (PoE), Auto Smartports, VLAN, and QoS, these switches are the perfect foundation to add business-grade wireless to a network.
- Unified communications. The Cisco 200 Series provides QoS features to enable you to prioritize delay-sensitive traffic in your network and let you converge all of your communications solutions – such as IP telephony and video surveillance – onto a single Ethernet network. Cisco offers a complete portfolio of IP telephony and other unified communications products designed for small businesses, and Cisco 200 Series switches have been rigorously tested to help ensure easy integration and full compatibility with these and other vendor products.
