Model Suffix Breakdown

• 26S: 22 dedicated 100/1000 Mbps SFP fiber downlink slots for long-distance single/multimode fiber connections to remote IEDs, distributed vision stations and field sensors
• 2C: Two dual-media combo ports (shared 100/1000 SFP fiber + auto-MDI-X 10/100/1000BASE-T RJ45 copper), only one media type active per port for flexible short-reach copper local connections to HMIs, PLCs and cabinet-side sensors
• Hidden uplink ports: 4 independent 1G SFP uplink slots for fiber backbone trunking
• No P marking: Non-PoE hardware architecture with no integrated inline power supply
• E: Extended harsh-environment variant with full PCB anti-corrosion conformal coating, expanded sealed-cabinet temperature tolerance, reinforced surge and EMC noise suppression, certified for continuous long-term operation inside sealed zero-airflow enclosures, offshore platforms, underground mines and coastal corrosive locations
• IE-9300 Base Platform: No hardware stacking capability, dual hot-swappable redundant AC/DC field-replaceable power modules

This compact 1RU all-metal IP30 fanless passive convection chassis eliminates rotating fan assemblies to remove single-point mechanical failure risks and drastically cut long-term field maintenance expenses. Dual field-replaceable redundant AC/DC power modules provide seamless automatic power failover to sustain uninterrupted industrial OT operation. Full conformal coating protects circuit boards against dust, moisture, salt fog and mixed corrosive gas, a core advantage for fully sealed cabinet installations lacking forced cooling airflow. Four Gigabit SFP uplinks support high-volume LACP link aggregation and multi-ring topologies including REP, MRP and DLR with sub-50ms ultra-fast failover convergence, suitable for long-distance machine vision streaming, distributed multi-camera surveillance and wide-area power grid IED interconnection. A swappable industrial SD flash card and front-panel USB-A host port enable zero-touch device replacement, bulk configuration backup and mass zero-touch deployment across geographically dispersed industrial sites.

Preloaded Network Essentials IOS XE firmware integrates native IEEE 1588v2 PTP transparent/boundary clock for microsecond-level OT synchronization, plus full native compatibility with core OT communication protocols: EtherNet/IP, PROFINET, Modbus TCP and GOOSE for power grid substation IED coordination. Layer 2 NAT and static IPv4 routing enable cross-subnet remote site segmentation, while multi-layer ACL filtering, port security and encrypted management channels strengthen the industrial edge against unauthorized network intrusions.

Powered by industrial-grade high-performance switching ASIC, 4GB DRAM and 8GB onboard flash storage, the IE-9300-26S2C-E delivers 56 Gbps non-blocking switching capacity and 41.66 Mpps wire-speed forwarding rate for 64-byte frames. Optimized low-jitter packet buffering prioritizes time-sensitive motion control signals, multi-stream industrial surveillance footage and high-volume IIoT sensor telemetry data. Passive heat sink architecture enables silent, 24/7 maintenance-free continuous operation in both fully sealed zero-airflow cabinets and ventilated industrial control rooms.
