IEM-3300-16T - Cisco Catalyst IE3300 16-Port GE Copper Module

Cisco Catalyst IE3300 Rugged Series expansion module adding 16 non-PoE Gigabit Ethernet copper ports for industrial network scaling.

The Cisco IEM-3300-16T is a rugged expansion module engineered for the Cisco Catalyst IE3300 Rugged Series of industrial switches. It adds sixteen non-PoE 10/100/1000 Gigabit Ethernet copper (RJ-45) ports, allowing network administrators to significantly increase port density on a compatible IE3300 or IE3400 base switch without replacing the existing switch infrastructure. Designed for DIN-rail mounting, the module is built to withstand harsh industrial conditions such as extreme temperatures, shock, vibration, and electromagnetic interference, making it suitable for factory automation, transportation, utilities, and other extended enterprise environments. Because it does not supply PoE, it is intended for data-only connections where connected devices are powered externally. The module integrates into the modular IE3300 chassis architecture to provide flexible, cost-effective network expansion.
