Cisco 500 Series switches provide the advanced feature set that growing businesses require, and that high-bandwidth applications and technologies demand.
Ethernet Connectivity
Choose from Fast Ethernet, Gigabit Ethernet and optional 10 Gigabit Ethernet connectivity.
Cisco 500 models offer one or five Gigabit Ethernet expansion slots, and the Cisco 500X models offer 10 Gigabit Ethernet expansion slots.
Power over Ethernet Plus provides up to 30 watts per port.
Advanced Features
Strong security features such as access control lists, guest virtual LANs, encrypted management data, and other advanced network defense features safeguard customer networks.
IPv6 support allows you to move up to the next generation of networking applications and operating systems without an extensive equipment upgrade.
Quality of service on all models prioritizes network traffic to keep critical network applications running at top performance.
Layer 3 static and dynamic IP routing provide advanced traffic management capabilities to segment networks.
Energy Efficiency and Design
Power-saving technology, including Energy Efficient Ethernet, reduces power consumption with the ability to enter sleep mode, turn off unused ports, and adjust power as needed.
More ports per Gigabit Ethernet switch includes 28- and 52-port Gigabit Ethernet switches.
Management and Investment Protection
Intuitive graphical interfaces, remote management capabilities, Textview command-line interface and automated deployment tools simplify setup and configuration.
Deploy an end-to-end voice network dynamically using a combination of Cisco Discovery Protocol, Link Layer Discovery Protocol-Media Endpoint Devices, Auto Smartports, and Voice Service Discovery Protocol.
All switches come with a limited lifetime warranty with next-business-day advance replacement, limited lifetime warranty on fans and power supplies, free software fixes for the term of the warranty, and one year of technical support to protect your investment.
