FAQs

Q: What industrial automation protocols does the IE-3105-18T2C-E support?
A: The switch natively supports EtherNet/IP (CIP), PROFINET, and Modbus protocols, making it ideal for integration with PLCs, sensors, and industrial controllers in manufacturing and utilities environments.

Q: What is Layer 2 Network Address Translation (L2NAT) and when is it needed?
A: L2NAT allows the switch to integrate devices with duplicate or overlapping IP addresses into the same network, a common scenario when connecting third-party OEM machinery or legacy equipment in industrial environments without reconfiguring device IPs.

Q: Can this switch operate in extreme temperatures and harsh conditions?
A: Yes, the IE-3105-18T2C-E is designed for extended industrial environments with an operating temperature range of -40°C to +75°C. Its fanless, rugged metal housing is built to withstand dust, vibration, electrical noise, and other challenging conditions typical in utilities, transportation, and manufacturing.

Q: Does this model include Power over Ethernet (PoE)?
A: No, the IE-3105-18T2C-E does not support PoE. If you need PoE capability for powering IP cameras, wireless access points, or other devices, consider alternative models in the Catalyst IE3100 series with PoE+ support.

Q: What is included with the Network Essentials license?
A: The Network Essentials perpetual license includes advanced Layer 2 switching features such as VLANs, Spanning Tree Protocol variants (STP/RSTP/MSTP), IGMP snooping, QoS, ACLs, Layer 2 NAT, and support for industrial protocols. It is a full-featured license suitable for most industrial deployments.
