What Is Industrial Unmanaged Switch?
Updated at Dec 24th 20241 min read
An unmanaged industrial Ethernet switch is a critical component in industrial networking, facilitating the connection of various devices within a network. Unlike managed switches, which offer advanced features and configurations, unmanaged switches provide a straightforward, plug-and-play solution. This simplicity makes them ideal for applications where ease of use is paramount. This article delves into the definition of industrial unmanaged switches, their key components, and how they compare to managed switches.
What Is an Industrial Unmanaged Switch?
An industrial unmanaged switch is a networking device specifically designed to connect multiple Ethernet devices in challenging industrial environments. These switches operate without the need for configuration, allowing for quick and easy installation. They function by directing data packets between connected devices, ensuring seamless communication across the network.
Key Features of Industrial Unmanaged Switches
Plug-and-Play Functionality
One of the standout features of industrial unmanaged switches is their plug-and-play functionality. This means that these unmanaged ethernet switches can be easily installed and put into operation without the need for complex configuration or setup processes. Users simply connect the switch to the power source and link it to the network devices using standard Ethernet cables. This simplicity allows for rapid deployment in various environments, making them ideal for projects with tight timelines or where technical expertise may be limited. The ease of use also reduces the likelihood of misconfiguration, ensuring that the network can become operational almost immediately.
Durability
Industrial unmanaged switches are engineered for durability, making them suitable for deployment in harsh industrial environments. These unmanaged switches are built to withstand extreme conditions, including high and low temperatures, vibrations, and exposure to dust, moisture, and other environmental hazards. Many models feature ruggedized housings constructed from robust materials, often rated with an Ingress Protection (IP) code, such as IP41. FS offers IES2100 series unmanaged ethernet switches, which are equipped with an IP41 metal enclosure to withstand a high degree of vibration and dust while operating in industrial environments from -40° to 75°C.
This rating indicates that the Industrial unmanaged switch is dust-tight and can withstand immersion in water, ensuring reliable operation even in the most challenging conditions. The enhanced durability of these switches minimizes the risk of failure and extends their lifespan, making them a wise investment for industrial applications.
Cost-Effectiveness
Industrial unmanaged switches are typically more affordable than managed switches, primarily due to their simplified design and lack of advanced features. Their straightforward operation means that they do not require the additional costs associated with configuration and management, making them a budget-friendly option for many organizations. This cost-effectiveness is especially beneficial for companies that need to deploy multiple switches across a large industrial network. By choosing unmanaged switches, organizations can achieve significant savings while still ensuring reliable connectivity for their devices. Additionally, the reduced complexity means lower maintenance costs and fewer resources spent on training personnel, further enhancing their overall value.

Industrial Managed Switch vs. Industrial Unmanaged Switch
While both managed and unmanaged switches serve the essential function of connecting devices within a network, they differ significantly in their capabilities:
Feature | Industrial Managed Switch | Unmanaged Industrial Switches |
Configuration | Requires setup and management | Plug-and-play, no configuration needed |
Control | Offers features like VLANs, QoS, and SNMP | Basic data forwarding without management features |
Monitoring | Supports network monitoring and diagnostics | Limited or no monitoring capabilities |
Cost | Typically more expensive | More cost-effective |
Components of Industrial Unmanaged Switches
Industrial unmanaged switches are constructed with several essential components that ensure reliable operation in demanding conditions. Here’s an in-depth look at these key components:
Ethernet Ports
The Ethernet ports on industrial unmanaged switches come in various configurations, typically ranging from 5 to 16 ports. FS offers IES2100 series unmanaged ethernet switches, which are available with 8 or 5 10/100BASE-T RJ45 Ports to provide secure access for high-speed applications in the industrial space. This flexibility allows users to connect multiple devices, such as sensors, cameras, and controllers, facilitating seamless communication. These ports are designed to support standard Ethernet cables (e.g., Cat 5e or Cat 6), ensuring broad compatibility with various network devices.
Power Supply
Many industrial unmanaged switches feature a wide input voltage range, enabling them to function effectively in diverse environments. This adaptability is crucial in industrial settings where power sources can vary significantly. Additionally, many switches offer redundancy options, such as dual power inputs, to ensure continuous operation in the event of a power source failure. IES2100 series unmanaged ethernet switches equipped with dual redundant power inputs. This feature not only enhances reliability but also minimizes downtime, which is vital for maintaining operational efficiency.
Housing
The housing of industrial unmanaged switches is engineered to withstand harsh environmental conditions. These switches are often constructed with rugged enclosures rated with Ingress Protection (IP) codes, such as IP30 or IP67, which denote their resistance to dust and moisture. For instance, switches with an IP67 rating can endure complete immersion in water, making them suitable for extreme conditions. The materials used—whether metal or high-grade plastics—not only protect the internal components but also aid in effective heat dissipation, essential for optimal performance.
MAC Address Table
The MAC (Media Access Control) address table is a vital component of industrial unmanaged switches, facilitating the efficient forwarding of data packets. Each device connected to the switch is assigned a unique MAC address, which the switch utilizes to direct incoming data to the appropriate port. This process helps minimize network congestion and ensures that data packets reach their intended destination promptly. The size of the MAC address table may vary among switches, so it is important to choose a switch with a sufficiently large table to accommodate the number of devices in your network. An effectively managed MAC address table enhances overall network performance and security by reducing unnecessary broadcast traffic.
Conclusion
Understanding the components and functionality of industrial unmanaged switches is essential for selecting the right device for your networking needs. These switches offer a reliable, cost-effective solution for connecting devices in industrial settings, ensuring seamless communication and operational efficiency. By considering the features and specifications outlined in this article, users can make informed decisions to optimize their industrial networks.
