The Cisco Industrial Ethernet IE-4000-8T4G-E is a rugged, Layer 2 managed industrial Ethernet switch engineered for reliable operation in harsh, mission-critical environments such as factories, substations, transportation systems, and utilities. Designed to deliver secure and resilient network connectivity, this switch combines hardened hardware with advanced industrial networking features.
The switch provides 8 Fast Ethernet RJ-45 downlink ports for connecting industrial devices such as PLCs, HMIs, sensors, and controllers, along with 4 Gigabit SFP uplink ports for high-speed fiber connectivity to aggregation or core networks. With a switching capacity of 7.2 Gbps and a forwarding rate of 5.36 Mpps, the IE-4000-8T4G-E ensures dependable performance for real-time industrial traffic.
Built for extreme conditions, the Cisco IE-4000-8T4G-E operates across an extended temperature range of -40°C to +75°C and features a fanless, convection-cooled design for increased reliability and reduced maintenance. The switch is certified for demanding industrial standards, including IEC 61850-3, IEEE 1613, EN50121-4, NEMA TS-2, and Class I Division 2, making it suitable for power substations, rail systems, and hazardous locations.
Running Cisco IOS, the switch supports essential Layer 2 features such as VLANs, STP/RSTP/MSTP, QoS, broadcast storm control, and industrial network resiliency technologies including REP, FlexLinks, and EtherChannel. Integrated security features - such as IEEE 802.1X authentication, DHCP snooping, and dynamic ARP inspection - help protect industrial networks from unauthorized access and threats.
With dual redundant 18–60 VDC power inputs, an integrated alarm relay, and support for DIN-rail or wall mounting, the Cisco IE-4000-8T4G-E is an ideal solution for organizations requiring secure, high-availability industrial Ethernet switching with long service life and low total cost of ownership.
