H3C S5120V3-28S-HPWR-LI 24xSFP + 4xSFP+ High-PoE Fiber Switch
24×1G SFP + 4×1G Combo Uplink High-Power L2/L2+ Full-Fiber Access Switch
Overview
The H3C S5120V3-28S-HPWR-LI is a high-power full-fiber access switch featuring 24 × 1G SFP downlink ports and 4 × 1G combo uplinks, delivering enhanced power and processing capacity for fiber-dense enterprise access scenarios.
As an HPWR model, it offers stronger internal PSU and higher system endurance, making it ideal for deployments requiring long-distance fiber wiring, better thermal reserve, and higher traffic stability-such as hospitals, hotels, campus dormitories, government buildings, and industrial office zones.
It supports the full L2/L2+ feature set in the LI series, including VLAN, MSTP, QoS, DHCP Snooping, ACL-lite, static routing-lite, and IGMP Snooping for multicast optimization.
Highlights
1. 24 × SFP Full-Fiber Access Ports
Perfect for EMI-sensitive, long-distance, or security-sensitive environments.
2. HPWR High-Power Architecture
Enhanced PSU ensures stability
✔ Under heavy traffic
✔ High temperature
✔ Full-port load conditions
3. 4 × Combo Uplinks for Versatile Backhaul
Supports copper or fiber depending on deployment.
4. L2/L2+ Enterprise Switching
Includes VLAN, MSTP, IGMP Snooping, ACL-lite, QoS, DHCP security.
5. Designed for Fiber-to-the-Room (FTTR/FTTD)
Ideal for hotels, dormitories, residential fiber coverage, and modern office buildings.
