Managed Switch Cisco Catalyst IE3400 L2 8x Gigabit Ethernet 3x USB

The Cisco Catalyst IE3400 is a managed Layer 2 rugged switch with 8 Gigabit Ethernet ports and 3 USB 2.0 ports. Designed for industrial and space-constrained deployments, it supports redundancy protocols, time-sensitive networking, and advanced security features to maintain high availability for mission-critical applications. The compact die-cast chassis and reduced footprint make it suitable for harsh environments and cabinet installations where space and power are limited.

Advantages

The platform offers modular port options including copper, fiber, and Power over Ethernet variants and can scale to support up to 26 Gigabit Ethernet ports depending on module configuration. Running Cisco IOS XE, the IE3400 provides open, standards-based APIs and multilayer security to enable automation and faster deployment of network services. The switch supports Intent Based Networking features, improving manageability and operational consistency at the IoT edge.

Suitable for

• Industrial Ethernet edge deployments
• Mission-critical networks requiring high availability and redundancy
• Space- and power-constrained cabinet installations
• IoT infrastructure upgrades to Gigabit Ethernet

How to use

Install the switch in a suitable industrial cabinet or rack space, ensuring proper grounding and adherence to the device's input voltage range (9.6–60 V DC). Configure network parameters through the IOS XE interface using the CLI, RESTCONF/NetConf APIs, or management tools that support Cisco standards. Populate required modules for copper, fiber, or PoE according to connectivity needs, and apply redundancy and time-sensitive networking settings for mission-critical traffic.

Recommendations

For reliable operation in harsh environments, mount the IE3400 in ventilated, properly grounded enclosures and verify power redundancy where necessary. Use IOS XE automation features to standardize configurations and monitor performance; test redundancy and time-sensitive networking settings during commissioning to confirm high-availability behavior.
