About the Cisco Industrial Catalyst IE3400 Rugged Switch IE-3400H-16T-E

The Cisco Industrial Catalyst IE3400 Rugged Series (IE-3400H-16T-E) delivers 36 Gbps switching capacity and 26.78 Mpps forwarding rate—enabling line-rate performance across industrial and mission-critical network environments. Built for extreme conditions, this fanless hardened switch operates reliably from -40°C to +70°C and supports dual DC input ranging from 12–48 VDC nominal, making it ideal for factory floors, utility substations, and remote infrastructure where traditional cooling and AC power are unavailable.

Network engineers and IT procurement teams benefit from Cisco's industrial-grade architecture: 16 copper 10/100/1000BASE-T ports (RJ-45) plus 4 shared 1G SFP uplink ports, all housed in a DIN-rail or rack-mountable form factor. The switch runs Cisco IOS XE with Layer 2/Layer 3 capabilities, supports up to 256 VLANs (802.1Q), and includes advanced redundancy protocols—MRP, PRP, HSR, RSTP, MSTP—alongside security features such as 802.1X, Cisco TrustSec, IP Source Guard, and Dynamic ARP Inspection. With typical power consumption of approximately 42W and an MTBF of approximately 400,000 hours, the IE-3400H-16T-E combines low energy draw with exceptional reliability. Application hosting via Cisco IOx enables Linux container and edge application deployment directly on the switch.

Industrial Deployment Scenarios

Substation automation and utility SCADA networks requiring extended temperature tolerance and ruggedized connectivity
Manufacturing and discrete production environments where DIN-rail mounting and fanless operation eliminate maintenance burdens
Remote oil and gas installations benefiting from dual DC power inputs and compact hardened design
Water treatment and critical infrastructure sites needing redundancy protocols (PRP, HSR, MRP) for zero-downtime operation
Edge computing deployments using Cisco IOx for on-device analytics and application hosting at the network edge
