2. Official Product Overview

The Cisco Catalyst IE-9300-26S2C-A is a high-density fanless hardened Layer 3 industrial Gigabit aggregation switch within the Cisco IE 9300 Rugged Industrial Switch Series, engineered for fiber-heavy large-scale OT edge aggregation deployments without inline PoE power delivery in well-ventilated, non-corrosive indoor industrial cabinet environmentsCisco. 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-9300-26S2C-E sealed cabinet variant.

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), supporting one active media type per port for flexible local copper 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 built-in inline power supply, designed exclusively for fiber-focused aggregation without powered copper endpoints
• 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 base platform: No hardware stacking support, 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 supplies deliver seamless automatic power failover to guarantee uninterrupted industrial OT operation. Four Gigabit SFP uplinks support LACP link aggregation and multi-ring topologies including REP, MRP and DLR with sub-50ms ultra-fast failover convergence, ideal for long-distance machine vision streaming, multi-stream 4K AI surveillance and large-scale power grid IED aggregation. Removable industrial SD flash card and front-panel USB 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 harden the industrial edge against unauthorized network intrusions.

Powered by industrial high-performance switching ASIC, 4GB DRAM and 8GB onboard flash storage, the IE-9300-26S2C-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 vision 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.
