FR-6S3204 is Smart Industrial Ethernet Switch independently developed by Fiberroad for industrial networking applications. We define it as the LITE model, wholly designed for small businesses, extremely cost-effective. This product adopts industry-leading technical standards and can provide stable and reliable Ethernet transmission with high quality. 

It offers and realizes Ethernet data exchange, convergence and long distance optical transmission with efficient bandwidth and reliable fiber optic network solutions for users. The industrial switch complies with various characteristics such as no fan, low power consumption, high reliability and stability, and easy to maintain.

Industrial Ethernet Switch adopt mature technology and open network standards, adapt to low temperature and high temperature, strong anti-electromagnetic interference, anti-salt fog, anti-vibration and anti-shake, equipped with redundant dual power supply (AC/DC), which can offer redundant mechanisms for critical applications that need always-on connections. It can also operate either at standard operating temperature range -20 to 70􀀁. Industrial switches support standard 19” rack mounts with IP40 protection and are perfect choices for harsh environments.

Main features:

  • 4x10/100/1000Base-TX RJ45 ports, 2x100/1000Base-FX Fast SFP ports
  • DIP Switch supports RSTP/VLAN/SPEED.
  • Support 9K bytes giant frame, compatible with various extension protocol
  • Support IEEE802.3az energy-efficient Ethernet technology
  • Electric 4KV surge protection, easy to use in an outdoor environment
  • Complete status indicator, working state at a glance
  • Power input polarity protection design
  • Aluminum case, no fan design
  • Installation method: DIN Rail /Wall mounting
  • Easy-to-use WebGUI management



  • RSTP switches to the ON position, which indicates RSTP is in disabled status.
  • VLAN switches to the ON position, which indicates VLAN is in enabled status. All LAN ports are only able to communicate with the SFP uplinks when this option is enabled.
  • To take effect the DIP Switch function while the ethernet switch is in operation, there is need to reboot the Ethernet switch after tuning the DIP switch.



To avoid damage to the equipment and personal injury caused by improper use, please observe the following precautions:

  • Keep the power off during installation, wear an anti-static wrist, and ensure that the anti-static wrist is in good contact with the skin to avoid potential safety hazards.
  • The switch can work normally under the correct power supply. Please confirm that the power supply voltage matches the Voltage indicated by the switch.
  • Before powering on the switch, please make sure that the power circuit is not overloaded, so as not to affect the normal operation of the switch and even cause unnecessary damage.
  • To avoid the risk of electric shock, do not open the case while the switch is working, even if it is not charged, do not open it yourself.
  • Before cleaning the switch, pull out the power plug of the switch. Do not wipe with a wet cloth. Do not use liquid to clean it.
  • The equipment installed in the rack is generally from bottom to top to avoid overload installation.
  • Avoid placing other heavy objects on the surface of the switch to avoid accidents.
