IEM-3300-8P - Cisco IE3300 8-Port GE PoE+ Expansion Module

Cisco Catalyst IE3300 Rugged Series 8-port Gigabit Ethernet PoE/PoE+ copper expansion module for industrial DIN-rail switch deployments.

The Cisco IEM-3300-8P= is an industrial-grade expansion module purpose-built for the Cisco Catalyst IE3300 Rugged Series (and compatible with IE3400) modular switches. It adds eight Gigabit Ethernet copper (RJ45) ports supporting PoE/PoE+ power delivery, expanding the base switch to a total of 18 system ports. Designed for fanless, convection-cooled operation in harsh environments, the module supports industrial automation, transportation, energy, mining, and smart city deployments where hardened networking equipment is required. It mounts on a DIN rail alongside the base switch and draws on the shared PoE power budget (up to 360W with all-GE base systems, or up to 480W with 10G base/IE3400 PoE base systems) to power connected devices such as IP cameras, wireless access points, and sensors.
