How to Choose The Right Industrial Ethernet Switch

What is Industrial Ethernet Switch

Industrial Ethernet Switch are Ethernet devices that feature Industrial-grade reliability, advanced network security, easy management, withstand Extreme Temperatures and Electromagnetic Interference.

They are specifically designed with Industrial chip, support IP30/IP40 protection, aluminum alloy shell, Din-rail or Rack mount installation, fanless, EMC level 4 protection, DC12-48V or AC/DC220V power supply, and can operate at wide temperature range from -40 to 75°C , widely used in Industrial automation, Data Center Network, Intelligent Transportation System, Electric Power Industry, and new energy.

In addition to this, Managed type Industrial switch can also provide some other advanced network managed functions, such as: Ring redundancy technology (failure recovery time<20ms), VLAN, multicast, Quality of Service, Speed control, port mirroring, fault alarm and firmware remote update, also support CLI, WEB, Telnet, SNMP management.

Difference between Managed and Unmanaged switches

Unmanaged switches are designed to plug-and-play, no configuration is required, usually used for smaller networks. on the other hand, managed switches provide advanced managed functions like VLAN, Quality of Service, Redundancy, SMMP, allow you to manage, configure, and monitor the settings of your LAN, often used in the core layer in a network.

Here are some difference between Managed Switches and Unmanaged Switches:

Managed Switches

Unmanaged Switches


VLANs,  redundancy, DHCP snooping, port mirroring, QoS, SNMP, etc.

Mostly  fixed configuration


Highly  configurable, control network traffic based on user-defined parameters

Plug and play with  limited configuration


Very  good. Security protocols for the data, management, and control planes.

Not very  good. Physical security only.

Plug and  play



Can support PoE










Data center, large  size enterprise networks

Small size business  network, home, etc.



Less  expensive

Difference between Industrial and Commercial switches

Commercial Switches are widely used in many fields, including residential and commercial buildings, healthcare, retail, and IT & telecommunication. Industrial switches are very different in terms of components, performance, anti-interference, applicable temperature, power supply selection, and installation methods.  

The main difference between Industrial Switches and Commercial Switches are as follows:

● Operating Voltage

Industrial switches support a wide operating voltage range, which can support DC12-48V or AC/DC220V. Commercial switches usually only support 220V.  

● Power Supply

Industrial network switches support redundant dual power supplies, one of which serves as a backup, while the commercial type is basically a single power supply.

● Installation method

Industrial switches adopt Din-Rail or Rack-mount installation, while Commercial type generally use Rack-mount or Desktop installation.

● Link failure recovery time

The Managed Industrial switches use MW-Ring network redundancy technology, and the failure recovery time less than 20ms, commercial switch takes 30s to 1min.

● Working temperature

Industrial Switch can withstand extremely operating temperature range from -40 to 75 °C, and commercial switch generally support 0-40°C.

● Others

Industrial-grade switches are designed with high quality components, much better than commercial grades in terms of heat dissipation, electromagnetic compatibility, dust resistance, and service life.

5 Types of Industrial Ethernet Switch

Understanding the Feature, Performace, Cost and Application of network switches will help you find the best solution for your project. Hereby, we would like to recommend 5 type of Industrial Ethernet Switches for your reference.

Unmanaged Switches

Unmanaged Switches are typically used for simply connectivity. they're designed to be plug and play, not necessarily need to be configured or watched, simple and easy to set up.

Managed Switches

Managed Switches are designed to deliver the most comprehensive features, the highest levels of security, the most precise network management, and the greatest reliability.

In addition to including the functions of Unmanaged Switches, Managed Network Switches can enhance the functionality of a certain network by providing features such as QoS (Quality of Service), Simple Network Management Protocol (SNMP) and so on, to be controlled by a professional administrator via console port.

RS232/RS485 Industrial Ethernet Switches

This type Switch not only support Ethernet port, fiber port, but also support serial port like RS-232,RS-485. The RS232/485 port can connect with the device that can't support Ethernet port, such as PLC, RTU, HMI, Industrial instrument, meters, Sensors.it can be widely used in Industrial control and Industrial automation.

RS232/RS485 serial port support FOUR working mode:


The Serial server monitoring the set port and waits for the data sent by TCP client to connect to the Serial device.


The serial server initiated a TCP connection to the set IP address. If the link fails, the serial server will try to reconnect, if the link is successful, Bidirectional data will be transmitted between Serial devices and PC via the Serial server.


The Serial server sends the data of the Serial device to the specified IP network device in the form of UDP packet.The serial port server monitors the port and forwards all receive data to the serial port device.

◆ Modbus TCP(RTU) MODE

Choose Modbus TCP(RTU) mode, configure related serial port parameter through WEB management.

Note: RS232/RS485 Industrial Ethernet Switch only support Modbus RTU to TCP protocol, doesn’t support Modbus TCP convert to Modbus RTU, it requires Modbus Gateway function. you can click on our related products to view more.

Industrial PoE Switches

An Industrial PoE switch (Power over Ethernet) is a network device that transmits electrical power through the same cable that carries data. When connecting network devices such as IP cameras, VoIP phones, and wireless access points, the switch will detect whether they are compatible with PoE and automatically enables PoE power transmission to these endpoints. This’s why PoE switches are also classified as Layer 2 Power Sourcing Equipment (PSE).

Each component of the Industrial PoE switch is designed and rigorously tested to handle extremely harsh environments subject to a wide range of operating temperature, vibration and shock, and protection from ESD (Electrostatic discharge), EMI (Electromagnetic Interference) and electrical surge.

PoE switches support IEEE802.3af(15.4W),802.3at PoE+(30W),802.3bt PoE++(95W), save installation and maintenance costs by reducing the need for external power supply, additional wires, power outlet.

Industrial PoE switches provide fixed ST, SC and FC connectors, or Small Form Pluggable (SFP) transceivers with LC connector. Fiber ports support multimode(850nm) or single-mode(1310/1550nm) and dual fiber or single-fiber with a maximum distance can reach 120km. SFP models also support CWDM o DWDM wavelengths.

UPCOM Company full range of PoE product lines include 1-port, 5-port,8-port,16-port,24-port Unmanaged or Managed Switches, it also provide PoE Injectors, PoE Splitters, Extenders designed for indoor and outdoor applications.
