Description
Key Features & Benefits
- High Port Density with PoE+: Features 48 x autosensing 10/100/1000BASE-T RJ-45 ports, including 4 dual-personality RJ-45/SFP ports, all supporting IEEE 802.3at Power over Ethernet Plus (PoE+). It offers a substantial 370W PoE budget (expandable to 740W with an optional external power supply) to power numerous network devices.
- Scalable Architecture: Provides two expansion module slots that can each support two-port 10GbE expansion modules, delivering high scalability and investment protection for growing network bandwidth needs.
- Intelligent Resilient Fabric (IRF) Technology: Allows multiple switches to be virtualized and managed as a single logical device, which increases network resilience, performance, and availability while simplifying operational complexity.
- Advanced Layer 3 Services: Supports static IPv4 and IPv6 routing, diversified services, and robust QoS (Quality of Service) policies to prioritize critical data, voice, and video traffic.
- Comprehensive Security and Management: Includes comprehensive security control policies such as 802.1X authentication, MAC-based authentication, and dynamic ARP protection. It is manageable via CLI, secure web GUI (HTTPS), or SNMP.
