Model Suffix Breakdown
-
18U: Eighteen 10/100/1000BASE-T Gigabit RJ45 downlink ports, fully IEEE 802.3bt Type 4 4PPoE capable, delivering up to 60W power output per single port for high-consumption industrial field endpoints
-
4X: Four independent dedicated 10G SFP+ fiber uplink slots (pure 10G fiber-only design, no shared combo RJ45 media, supporting multi-directional 10G trunking for mass AI machine vision streams, 4K surveillance video and ultra-low-jitter industrial control traffic)
-
E: Extended wide-temperature hardened chassis with reinforced PCB thermal layout, enhanced substation-grade EMC/EMI surge suppression and anti-corrosion coating, certified for stable 24/7 continuous operation inside fully sealed zero-airflow industrial enclosures with extreme hot/cold swings, heavy dust, salt fog, moisture and corrosive gas electrical interference
This industrial high-power UPOE 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 filtering. Fanless zero-moving-part architecture eliminates mechanical fan failure points and drastically cuts long-term field maintenance overhead for remote unmanned underground mining, offshore oil & gas platforms, coastal roadside traffic control cabinets and power substation sealed control panels.
Four standalone 10G SFP+ fiber uplinks support high-speed multi-fiber link aggregation trunking, redundant REP/MRP/HSR/PRP/DLR sub-50ms zero-failover industrial ring topologies and multi-path high-bandwidth backbone connections to multiple central control room core switches, eliminating fiber uplink bandwidth bottlenecks for high-throughput machine vision and mass surveillance workloads. Modular expansion slots support IEM-3500 series add-on modules to scale total port count up to 26 ports for future network capacity expansion.
Integrated 1080W full-load UPOE power budget delivers native 60W power to high-consumption industrial endpoints: AI 4K PTZ IP cameras, industrial Wi-Fi 6/6E APs, multi-touch HMI panels, high-speed machine vision scanners and safety IoT monitoring sensors, eliminating separate external power injectors and simplifying field wiring layout.
Preloaded universal Cisco IOS XE Network Essentials firmware with native license-free IEEE 1588v2 PTP transparent/boundary clock precision timing, it natively supports mission-critical industrial automation standards: REP Resilient Ethernet Protocol, MRP Media Redundancy Protocol, HSR/PRP lossless parallel redundancy, EtherNet/IP, PROFINET, Modbus TCP and GOOSE for power grid IED synchronizationCisco. Built-in Layer 2 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 real-time asset inventory management.
Equipped with industrial multi-core high-speed switching chipset, 4GB DRAM and front-access removable SD flash storage (sold separately as optional accessory), it provides 56 Gbps non-blocking switching capacity and 41.66 Mpps wire-speed forwarding rate for 64-byte frames. Integrated IEEE 802.1Qbu / 802.3br TSN frame preemption minimizes latency and jitter for time-sensitive 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.
