Model Suffix Breakdown
-
18T: Eighteen 10/100/1000BASE-T Gigabit RJ45 copper downlink ports, non-PoE unpowered interfaces
-
2X: Two independent dedicated 10G SFP+ fiber uplink slots (pure 10G fiber-only design, no shared combo RJ45 media, supporting 10G high-bandwidth trunking for mass video and heavy industrial control traffic)
-
E: Extended wide-temperature hardened chassis with reinforced PCB thermal layout and enhanced substation-grade EMC/EMI surge filtering, validated for stable long-term continuous operation inside fully sealed zero-airflow industrial enclosures with extreme hot/cold swings, heavy dust, salt fog and corrosive gas interference
This industrial non-PoE switch adopts heavy-duty IP30 die-cast metal fanless passive convection cooling chassis, dual redundant isolated wide-range 9.6–60 VDC DC power inputs, and reinforced substation-class electrical noise suppression. Fanless zero-moving-part design eliminates mechanical fan failure points and drastically cuts long-term maintenance overhead for remote unmanned underground mining, offshore oil & gas platforms, coastal roadside traffic enclosures and power substation sealed control panels.
Two standalone 10G SFP+ fiber uplinks support high-speed multi-fiber trunking, redundant REP/MRP/HSR/PRP zero-failover ring topologies and multi-path high-bandwidth backbone connections to multiple central control room core switches without copper uplink tradeoffs. Modular expansion slot supports IEM-3400 series add-on modules to scale total port count up to 26 ports for future capacity growth.
Preloaded universal Cisco IOS XE Network Essentials firmware with native license-free IEEE 1588v2 PTP precision timing, it natively supports mission-critical industrial automation standards: REP Resilient Ethernet Protocol, MRP Media Redundancy Protocol, HSR/PRP parallel redundancy, EtherNet/IP, PROFINET, Modbus TCP and GOOSE for power grid IEDs. Built-in L2 NAT and static Lite Layer 3 IPv4 routing enable cross-subnet remote site IP translation and inter-VLAN forwarding without extra license upgrades. It also supports Cisco IOx local edge application hosting and Cyber Vision industrial threat monitoring for full OT cybersecurity visibility and asset inventory management.
Equipped with industrial multi-core high-speed chipset, 4GB DRAM and front-access removable SD flash storage (sold separately as optional accessory), it provides 28 Gbps non-blocking switching capacity and 20.88 Mpps wire-speed forwarding rate for 64-byte frames. Low-latency optimized packet buffering ensures consistent transmission of real-time PLC motion control signals, mass multi-stream 4K industrial surveillance video and high-volume distributed IIoT sensor data. Passive heat sink fanless design delivers silent, maintenance-free 24/7 continuous operation in fully sealed unventilated industrial enclosures with zero airflow.
