28-port 10/100/1000, 4 x Gigabit Ethernet (2 combo Gigabit Ethernet + 2 1GE/5GE SFP), Stackable, Managed, 72 Gbit/s, 800 MHz ARM, 256MB, 32MB Flash, PoE
Cisco SG500-28P. Switch type: Managed, Switch layer: L3. Basic switching RJ-45 Ethernet ports quantity: 28. MAC address table: 16000 entries, Switching capacity: 72 Gbit/s. Networking standards: IEEE 802.1D, IEEE 802.1Q, IEEE 802.1s, IEEE 802.1w, IEEE 802.1x, IEEE 802.3, IEEE 802.3ab, IEEE.... Power connector: DC-in jack. Power over Ethernet (PoE)The Cisco 500 Series Stackable Managed Switches provide the ideal technology foundation for demanding business networks. They offer the perfect mix of advanced features needed to ensure the availability of critical applications. Now you can protect business information and provide a solid foundation for your current business applications, as well as those you are planning for the future-all in a package you can afford. Cisco 500 Series Stackable Managed Switches support: - High Reliability and Resiliency: Keep your network up and running with advanced redundancy and availability features that reduce downtime and improve network resiliency so your business never slows down. - Strong Security: Advanced security features protect your business data and keep unauthorized users off your network. - Power-Efficient: A variety of power-saving features across all models provide one of the industry's most extensive energy-efficient switching portfolios. - Simplified Network Setup and Operations: Intuitive browser-based tools, auto-configuration and discovery, and true stacking make theses switches easy to use and manage, and simplify day-to-day network operations. - Peace of Mind: All Cisco 500 Series Switches are protected for the life of the product by the Cisco Limited Lifetime Hardware Warranty, including next-business-day advance replacement (where available). 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 (PoE+) provides up to 30 watts per port. Advanced Features - Strong security features such as access control lists (ACLs), guest virtual LANs (VLANs), 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 (QoS) on all models prioritizes network traffic to keep critical network applications running at top performance. - Layer 3 static (500 models) and dynamic (500X models) 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 (instead of 20 or 44 ports with four shared ports, as in traditional devices). Management and Investment Protection - Intuitive graphical interfaces, remote management capabilities, Textview command-line interface, Cisco Configuration Assistant, and automated deployment tools simplify setup and configuration. - Deploy an end-to-end voice network dynamically using a combination of Cisco Discovery Protocol (CDP), Link Layer Discovery Protocol-Media Endpoint Devices (LLDP-MED), Auto Smartports, and Voice Service Discovery Protocol (VSDP). - All switches come with a limited lifetime warranty with next-business-day advance replacement (where available), 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.
