Industrial-Grade PoE+ Switch With 28 Ports , Wide Temp Range &
ERPS Ring , H3C LS-IE4320-28P-S
The H3C LS-IE4320-28P-S is a rugged industrial-grade PoE+ Ethernet
switch designed for harsh environments, offering high reliability,
advanced redundancy, and flexible connectivity. With 24× Fast
Ethernet ports, 4× Gigabit SFP slots, and 370W PoE+ budget, it
powers IP cameras, wireless APs, and industrial IoT devices while
ensuring stable data transmission in extreme conditions.
Key Features & Benefits
✔ Industrial Durability – Operates in -40°C to 75°C environments
with fanless, metal housing, EMI/anti-surge protection, and DIN
rail/wall mounting for easy deployment.
✔ High-Power PoE+ Support – 24× IEEE 802.3af/at PoE ports (30W max
per port, 370W total) for PD devices, reducing cabling complexity.
✔ Fast Network Redundancy – ERPS (Ethernet Ring Protection,
<50ms failover) and STP/RSTP/MSTP ensure uninterrupted
operations in critical applications.
✔ Gigabit Fiber Uplinks – 4× SFP slots for long-distance fiber or
copper uplinks (up to 120km with optics).
✔ Enhanced Security – ACL, port security, DHCP snooping, and
MAC/IP/port binding prevent unauthorized access.
