An In-Depth Look at Cisco Industrial Ethernet 3400 Series Switches

In the vast world of networking, Cisco has long stood as a beacon of innovation and reliability. With their commitment to providing solutions tailored for various industries and environments, it's no surprise that their Industrial Ethernet Switches have gained significant attention in the market. Today, we'll be diving deep into the Cisco Industrial Ethernet 3400 Series.

Overview of the 3400 Series

The Cisco Industrial Ethernet 3400 Series is designed specifically for industrial environments. These switches are rugged ensuring that they can withstand the harshest of conditions, from extreme temperatures to high levels of dust and humidity. They're not just built tough; they're also built smart, with features that cater to the unique requirements of industrial networking. 

Let's explore the top three industrial ethernet switches.

IE-3400-8T2S-E: The Versatile Powerhouse

Starting with the IE-3400-8T2S-E, this model is a testament to Cisco's dedication to versatility and power. This switch belongs to the IE3000 series subset and offers 8 RJ-45 ports with PoE capabilities. What makes it stand out is its ability to support both 10/100 and 1000Base-T, ensuring that it can cater to a wide range of networking needs. The inclusion of 2 SFP ports further enhances its versatility.

But it's not just about the number of ports or their speeds. The switch is also Layer 3 managed, which means it's adept at routing as well as switching. This makes it an excellent choice for environments that require advanced networking functionalities. Plus, its rack-mountable design ensures that it can fit seamlessly into various setups.

IE-3400-8P2S-E++: Designed for Power and Efficiency

Next up is the IE-3400-8P2S-E++. Immediately noticeable is its focus on PoE (Power over Ethernet) with its 8 ports designed for 10/100Base-T. This makes it an ideal choice for devices that require both data and power over a single connection, such as IP cameras and access points. This efficient power distribution can greatly reduce the clutter of cables and the need for additional power sources. 

Additionally, the switch includes 2 SFP ports that support 1000Base-X, offering gigabit speeds for uplinking or connecting to high-bandwidth devices. Being a Layer 2 managed switch, the switch excels at bridging and switching functionalities, making it a go-to for many industrial setups. Its rail-mountable design further ensures that it can be securely fixed in place, a crucial feature for vibration-prone environments.

IE-3400-8T2S-A: The Reliable Workhorse

The IE-3400-8T2S-A might seem similar to the first model we discussed, but it brings its own set of strengths to the table. With 8 ports supporting 10/100Base-T and 2 SFP ports for 1000Base-X, it strikes a balance between speed and efficiency. Like the IE-3400-8P2S-E++, this switch is Layer 2 managed, focusing on delivering reliable switching capabilities. Its rail-mountable design is a testament to its ruggedness ensuring that it remains stable and operational even in challenging industrial environments.

Benefits of Cisco Industrial Ethernet 3400 Series Switches

Advanced Security Features: 

One of the standout features of the 3400 Series is its robust security suite. These switches come equipped with features like Dynamic Host Configuration Protocol (DHCP) snooping, IP Source Guard, and Dynamic ARP Inspection. These capabilities help prevent malicious users from intercepting traffic or launching attacks against the network, ensuring that your industrial operations remain secure and uninterrupted.

Easy Configuration and Management: 

With Cisco's Device Manager and Network Assistant, setting up and managing the 3400 Series becomes a breeze. These intuitive interfaces allow for easy drag-and-drop configurations and provide real-time monitoring, simplifying the management process and reducing the need for complex command-line setups.

Industrial Design and Certifications:

The 3400 Series is not just rugged in name. These switches have undergone rigorous testing and have received certifications like the International Electrotechnical Commission (IEC) 61850 and IEEE 1613 for utility substations. This assures users of their durability and reliability in the most challenging environments.

Environmental Sustainability: 

Cisco is committed to reducing its carbon footprint, and the 3400 Series is no exception. These switches are designed to be energy-efficient, reducing power consumption without compromising on performance. This not only leads to cost savings but also aligns with global sustainability goals.

Scalability for Future Growth: 

As industries grow, so do their networking needs. The 3400 Series is designed with scalability in mind, ensuring that as your operations expand, your networking infrastructure can adapt without the need for a complete overhaul.

Multicast Features: 

In industrial settings, multicast traffic, where data is sent to multiple destinations simultaneously, is common. The 3400 Series supports advanced multicast features ensuring efficient data transmission for applications like video surveillance or real-time data sharing.

Network Resilience: 

Downtime can be costly in industrial settings. With features like FlexLinks, the 3400 Series ensures rapid recovery from network hiccups, maintaining high availability and minimizing operational disruptions.

Seamless Integration with Other Cisco Products: 

If you're already invested in Cisco's ecosystem, integrating the 3400 Series is seamless. Whether it's routers, firewalls, or other networking devices, the 3400 Series works harmoniously within the Cisco environment, providing a unified and cohesive networking solution.


Cisco's Industrial Ethernet 3400 Series is a clear reflection of the company's commitment to delivering top-notch networking solutions for the industrial sector. Whether you're looking for advanced routing capabilities, efficient PoE distribution, or a reliable switching solution, the 3400 Series has got you covered. Incorporating these switches into your industrial setup not only ensures seamless connectivity but also brings the reliability and durability that Cisco is renowned for.
