H3C LS-5120V3-28F-LI-GL Ethernet Switch is a second-generation smart managed switch developed by H3C, designed for enterprise networks requiring high performance, high port density, and easy installation. It provides 24 × 100/1000BASE-X fiber ports, 2 × 10/100/1000BASE-T combo ports, 2 × 1G SFP ports, and 2 × 1G/10G SFP+ uplink ports, delivering flexible and high-speed connectivity options. The switch is suitable for enterprise and metro network environments, where it can function as an access or aggregation device to provide reliable Gigabit and 10GE uplinks. It supports Intelligent Resilient Framework (IRF) technology, allowing multiple switches to be virtualized into a single logical entity for improved scalability, high availability, and simplified management. This makes it ideal for modern enterprise, campus, and service provider networks requiring resilient and scalable fiber-based switching.

H3C LS-1850V2-28X-GL Layer 2 Switch is a high-performance Gigabit access switch designed for enterprise and SMB networks. It provides 24 × 1GE Ethernet ports and 4 × 1GE/10GE SFP+ uplink ports, delivering flexible and scalable connectivity for wired and fiber networks. The switch supports advanced Layer 2 features, including VLAN segmentation, security policies, and efficient traffic management for stable network operations. It is suitable for enterprise, campus, education, and surveillance deployments requiring reliable access switching with high-speed uplink capability. Its compact design ensures easy installation, maintenance, and efficient network expansion.

The LS-1850V2-28X-HPWR-GL is a Layer 2 Gigabit Ethernet switch designed for small and medium businesses (SMBs) with high port density and PoE+ functionality. It offers basic network management capabilities through a web interface for configuration, monitoring, and troubleshooting. The switch offers a significant number of Gigabit Ethernet ports, likely 28 x 10/100/1000 Mbps RJ45 ports, for connecting devices to the network. It includes PoE+ functionality, supporting the IEEE 802.3at standard, which delivers up to 30W of power per port, eliminating the need for separate power adapters. Other specifications include 4 additional SFP ports for connecting to fiber optic cabling for longer distances or core network switches. The switch is rack-mountable for space-saving installation in network racks and has a web interface for management. Benefits for SMBs include increased scalability, PoE+ support, and basic management features for configuration, monitoring, and troubleshooting.

H3C S5120V3-LI Ethernet switch product is independently developed by New H3C Technologies Co., Ltd. (H3C). It is a second-generation smart managed switch designed for network environments that require high performance, high port density, and easy installation.

H3C S5120V3-LI Ethernet switch provides 10/100/1000Base-T adaptive Ethernet ports or SFP/SFP+ optical ports. In enterprise networks, it can be used as an access device to provide Gigabit to desktops; in metropolitan area networks or networks of industrial users, it can provide Gigabit access to end users or tandem low-end switches downwards, and connect to high-capacity L3 switches through Gigabit fiber or link aggregation upwards.

H3C S5120V3-LI Ethernet switch series supports the innovative Intelligent Resilient Framework (IRF) technology, which allows users to connect up to nine S5120V3-LI switches to form a logically independent entity to build a highly reliable, easily scalable, and manageable new intelligent network.
