Cisco ESS-3300-CON-E ESS3300 Main Board 2 10G + 8 GE | Industrial Switch — ESS-3300-CON-E

Sustain industrial network uptime where fans, dust, and heat are liabilities. Cisco’s ESS3300 main board is built for conduction-cooled operation, making it a strong fit for sealed cabinets and other environments where passive thermal design matters. With 2 10G ports for uplinks and 8 Gigabit Ethernet ports for downstream connectivity, it gives infrastructure teams the bandwidth headroom needed for control traffic, aggregation, and edge device access. This model is aimed at deployments that value predictable operation over commodity switching. The fixed-port design reduces complexity, while the industrial form factor supports installations that must stay online in demanding conditions. For teams standardizing on Cisco industrial networking, it offers a practical balance of port mix, thermal resilience, and deployment simplicity. Choose this board when the network must keep moving through temperature stress, enclosure constraints, or locations where active cooling is not desirable. It is a purpose-built component for industrial switching architectures that need reliable connectivity at the edge. Ideal For Factory automation networks with sealed control cabinets Industrial edge aggregation for sensors and controllers Utility and infrastructure sites with limited airflow Vibration-sensitive installations requiring passive cooling Why This Product 1 Conduction-cooled design instead of fan-based cooling 2 2 10G uplinks for faster aggregation than basic Gigabit-only models 3 8 GE ports for mixed edge connectivity 4 Fixed-system architecture for simpler industrial deployment
