IE-9300 Platform Overview: Supports hardware stacking via combo SFP uplink interfaces; fitted with 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 significantly reduce long-term field maintenance costs. 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 key advantage for fully sealed cabinet installations lacking forced cooling airflow. Four dual-media combo 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 large-scale copper-based production line aggregation, 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-9300-24T4C-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.
