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
-
2X: Two independent dedicated 10G SFP+ fiber uplink slots (pure 10G fiber-only design, no shared combo RJ45 media)
-
E: Extended wide-temperature hardened chassis with reinforced PCB thermal layout and enhanced industrial EMC/EMI filtering, validated for reliable continuous operation inside unventilated sealed cabinets; preloaded with permanent Cisco IOS XE Network Essentials base license
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 surge & noise suppression. Fanless zero-moving-part design eliminates mechanical fan failure points and drastically reduces long-term maintenance overhead for remote unmanned underground mining, offshore platforms, coastal roadside traffic enclosures and power substation sealed control panels.
Integrated ultra-high-capacity 1080W full-load UPOE power budget delivers native 60W power to high-consumption industrial endpoints: 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. Two standalone 10G SFP+ fiber uplinks support high-speed multi-fiber trunking, redundant REP/MRP ring topologies and multi-path high-bandwidth backbone connections to multiple central control room core switches without copper uplink tradeoffs. Modular expansion slots support IEM-3300 series add-on modules to scale total port count up to 26 ports for future capacity growth Cisco.
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, 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 edge application hosting and Cyber Vision industrial threat monitoring for full OT cybersecurity visibility and asset inventory management.
Equipped with industrial high-performance 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 industrial 4K 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.
