Network switch module Cisco IEM-3400-8T Gigabit Ethernet 1000 Mbit/s

The Cisco IEM-3400-8T is a compact network switch module from the Catalyst IE3400 Rugged Series that delivers Gigabit Ethernet connectivity at 1000 Mbit/s. Designed for industrial and space-constrained environments, this module supports intent-based networking features in a small form factor and typical power consumption of 18 W.

Advantages

The module offers full Gigabit Ethernet performance in a rugged, compact design and is expandable within the Catalyst IE3400 family to support larger port counts. Its low power consumption and standardized dimensions (152 mm width, 66 mm depth, 135 mm height) make it suitable for installations where space and power are limited. The product integrates with Cisco industrial networking features to provide a future-proof solution for Ethernet-based applications.

Suitable for

• Industrial Ethernet installations
• Compact or space-limited network racks and enclosures
• Edge networking and modular switch systems
• Applications requiring Gigabit (1000 Mbit/s) connectivity
