Ethernet A/B Switch


Ethernet A/B Switch is a device used to select between two Ethernet sources for a single output. It is commonly used in network environments where redundancy and failover are critical. This article will provide a detailed explanation of Ethernet A/B Switch, its features, and its applications.


1. Dual Ethernet Inputs: The Ethernet A/B Switch is designed with two Ethernet input ports, labeled A and B. These ports allow two different Ethernet sources to be connected to the switch simultaneously.

2. Single Ethernet Output: The switch has a single Ethernet output port labeled O. This port is used to connect the output of the switch to the desired network device.

3. Manual or Automatic Switching: The Ethernet A/B Switch can support both manual and automatic switching modes. In the manual mode, the user manually selects the desired Ethernet source using a physical switch on the device. In the automatic mode, the switch automatically selects the active Ethernet source based on predefined rules.

4. LED Indicators: The switch is equipped with LED indicators to provide visual feedback on the active Ethernet source and the selected mode of operation.

5. Easy Installation: The Ethernet A/B Switch is designed to be plug-and-play, making it easy to install and configure in any network environment. No additional software or drivers are required.


1. Redundant Network Connections: In environments where reliable network connectivity is crucial, the Ethernet A/B Switch can be used to provide redundant network connections. By connecting two different Ethernet sources to the switch, if one source fails, the switch can automatically switch to the backup source, ensuring uninterrupted network connectivity.

2. Failover Testing: The switch is also useful for testing failover scenarios. By simulating network failures on one of the Ethernet sources, the switch can be used to verify the effectiveness of failover mechanisms and ensure the network can recover seamlessly in case of a failure.

3. Load Balancing: In situations where network traffic needs to be distributed across multiple Ethernet sources, the switch can be used for load balancing. The switch can automatically distribute traffic between the two Ethernet sources, optimizing network performance and preventing overload on a single source.

4. Network Maintenance: During network maintenance or upgrades, the Ethernet A/B Switch can be used to temporarily divert network traffic from the primary source to a secondary source. This allows maintenance activities to be performed without affecting network availability.


The Ethernet A/B Switch is a versatile device that provides reliable network redundancy, failover testing, load balancing, and network maintenance capabilities. With its dual Ethernet inputs, easy installation, and manual or automatic switching options, it is an essential tool for ensuring uninterrupted network connectivity in critical network environments.
