The Cisco IEM-3300-6T2S is a high-performance expansion module designed to enhance the flexibility and port capacity of the rugged Catalyst IE3300 Rugged Series switches. With six Gigabit Ethernet (GE) copper RJ-45 ports plus two 1 Gigabit SFP fiber uplink ports, this module enables seamless expansion of industrial networks with both copper and fiber connectivity in one compact unit.

Built to thrive in demanding industrial and extended enterprise environments, the IEM-3300-6T2S supports a wide operating temperature range (down to −40 °C) and rugged mounting options such as DIN-rail or wall-mount, making it ideal for manufacturing, transportation, smart-grid, and oil & gas applications.

The module integrates with the Cisco Catalyst IE3300 platform, which runs the IOS XE operating system, ensuring enterprise-grade features such as modular design, secure boot, image signing, advanced flow visibility, and industrial-grade reliability.

With this expansion module, system integrators and network engineers can tailor port counts to evolving connectivity needs without replacing the base switch, thereby optimizing cost and deployment flexibility.

In short: if you’re looking to scale a rugged industrial Ethernet switch setup — one that needs a mix of copper and fiber ports in a compact, hardened form-factor — the IEM-3300-6T2S is a smart addition to your Cisco Catalyst IE3300 environment.
