Description
H3C IE4320 Series — Industrial Ethernet Switches
The H3C IE4320 Series is a range of ruggedized industrial Ethernet switches engineered for harsh, mission-critical environments where standard commercial switches cannot operate reliably. Built to survive wide temperature extremes, vibration, dust and electrical noise, the IE4320 brings enterprise-grade Comware V7 switching intelligence to factory floors, substations, transportation networks and outdoor infrastructure.
Key specifications at a glance
Operating Temperature
−40 °C to +75 °C fanless operation — no moving parts to fail in extreme heat or cold.
Protection Rating
IP40 rated for dust and rugged ingress protection in industrial and outdoor cabinet deployments.
Software Platform
Runs H3C Comware V7 — the same enterprise OS used across the full H3C switching portfolio.
Form Factors
Available in compact DIN-rail mount and standard 19-inch rackmount formats to suit any enclosure.
PoE Support
Select models support PoE and PoE+ (UPWR) for powering cameras, access points and sensors.
Redundant Power
Rackmount models support dual redundant power configurations — AC+AC or DC+DC — for high availability.

Common series models
DIN-Rail models
Compact 6-port DIN-rail switch. Ideal for space-constrained industrial control panels where only a small number of ports are needed at each node.
12-port DIN-rail switch offering a balance of port density and compact form factor for mid-sized industrial panel deployments.
12-port DIN-rail switch with high-power PoE (UPWR) output — suitable for powering PTZ cameras, ruggedized access points and industrial sensors directly from the switch.
Rackmount models
28-port fibre-focused rackmount switch with SFP ports for long-distance fibre connections across large industrial sites or campus environments.
28-port rackmount with SFP and 10G SFP+ uplinks. Suited for aggregation at control room level with high-bandwidth uplink capacity.
28-port rackmount with high-power PoE and 10G SFP+ uplinks plus redundant power inputs — designed for demanding environments where both PoE delivery and power resilience are required.
52-port high-density rackmount switch with 10G SFP+ uplinks and support for redundant AC+AC or DC+DC power. The highest port count in the series, suited to industrial aggregation layers.
