It ships factory preloaded with permanent Network Advantage Cisco IOS XE license, unlocking full dynamic IPv4/IPv6 routing protocols, IEEE 802.1Qbu TSN time-sensitive networking, enterprise-grade industrial zero-trust security, IOx edge virtualization, Cisco Cyber Vision OT threat analytics, SD-Access fabric edge and TrustSec SGT micro-segmentation with no extra license upgrades required. It differs fundamentally from the conformal-coated extended-temperature IE-9300-24T4C-E sealed cabinet variant.

Model Suffix Breakdown

24T: Twenty-four dedicated 10/100/1000BASE-T Gigabit RJ45 copper downlink ports with auto MDI-X, for connecting PLCs, HMIs, industrial sensors, unpowered IP cameras and local field equipment
4C: Four independent dual-media combo uplink ports; each port supports either a 100/1000 SFP fiber transceiver or auto-MDI-X Gigabit RJ45 copper (only one media type active per port) to deliver flexible backbone trunking options
No P marking: Non-PoE hardware architecture without integrated inline power supply
A: Standard industrial temperature variant with uncoated PCB, limited to ventilated, low-humidity, non-corrosive indoor environments; not approved for long-term sealed cabinet, offshore, mining or coastal corrosive deployments
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. 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 Advantage 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, static & dynamic full IPv4/IPv6 routing enable cross-subnet remote site segmentation, while multi-layer ACL filtering, port security, MACsec 256-bit link encryption 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-A delivers 56 Gbps non-blocking switching capacity and 41.66 Mpps wire-speed forwarding rate for 64-byte frames. Optimized low-jitter packet buffering with IEEE 802.1Qbu TSN frame preemption minimizes latency for 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 only in ventilated industrial control rooms and climate-controlled indoor cabinet deployments.
