H3C S5120V3-28S-PWR-LI 24xSFP Fiber PoE Access Switch
24×1G SFP + 4×1G Combo Uplink Fiber Access Switch with PoE-Powered Relay/Conversion Support
⚠️ Note: This model is optical-only and does NOT provide PoE output.
"PWR" here refers to enhanced internal power/processing-not PoE capability.
Overview
The H3C S5120V3-28S-PWR-LI is a full-fiber L2/L2+ access switch with 24 × SFP downlink ports and 4 × combo uplinks, offering enhanced power reserves for scenarios requiring full-port load, long fiber distances, and elevated environmental stability.
This model is optimized for fiber aggregation and FTTD deployments, providing the robustness needed in high-density optical networks such as hotels, dormitories, hospitals, smart buildings, and industrial campuses.
Highlights
1. 24-Port Full-Fiber Access
Reliable long-distance fiber connectivity up to kilometers.
2. Enhanced Internal PWR System
Higher internal wattage allows:
✔ Better thermal stability
✔ Prolonged full-bandwidth operation
✔ Improved fail tolerance
3. 4 × Combo Uplinks
Flexible selection of RJ45 or SFP uplinks.
4. Full L2/L2+ Feature Suite
-
VLAN
-
MSTP
-
IGMP Snooping
-
ACL-lite
-
DHCP Snooping
-
QoS scheduling
5. Best for Fiber-Only Environments
No copper/RJ45 endpoints required on the access layer.
