The H3C S5120V3-LI Series is a next-generation Layer 3 Gigabit managed switch family engineered for enterprise campus networks, SMBs, education, hospitality, government, and industrial applications. Designed to provide high performance, reliability, and scalability, the series offers models with Gigabit Ethernet access ports, Gigabit SFP uplinks, 10G SFP+ uplinks, and PoE+ options to meet diverse deployment requirements. Built on H3C’s intelligent switching platform, the S5120V3-LI Series supports comprehensive Layer 2 and Layer 3 networking features, including static routing, RIP, OSPF, IPv4/IPv6 dual stack, VLANs, QinQ, Link Aggregation, QoS, ACLs, DHCP Snooping, 802.1X authentication, and advanced multicast capabilities. These features ensure secure, efficient, and uninterrupted network communication for modern business environments. The series incorporates IRF2 (Intelligent Resilient Framework) technology, allowing up to nine switches to operate as a single logical device for simplified management, enhanced redundancy, and seamless scalability. Selected compact models feature a fanless design for silent operation, while PoE+ variants provide up to 370W PoE budget to power IP phones, wireless access points, IP cameras, and other PoE-enabled devices. Green technologies such as Energy Efficient Ethernet (EEE) and automatic power-saving further reduce operating costs. Supporting Web GUI, CLI, SNMP, SSH, Telnet, and H3C iMC management, the S5120V3-LI Series delivers enterprise-class performance, robust security, and simplified administration, making it an ideal Gigabit access solution for growing networks.
