The Mark VIeS IONet Switch IS420ESWBH3A is a 24/28 VDC switch produced by General Electric, this model does not have any fiber ports, but has 16 copper ports. The IS420ESWBH3A switch requires a clamp if mounted on a din rail, and only screws if mounted on a panel.

An IS420ESWBH3AX Switch (Switch) is a network device used to connect devices in a computer network and transfer data between them. It plays a vital role in the network, mainly has the following functions:

1. Connect devices: The IS420ESWBH3AX switch provides a connection point for devices in the network, allowing multiple devices to communicate through it.

2. Data forwarding: The switch receives data from a device and forwards it to the correct port according to the MAC address of the target device, thus achieving data transmission between devices.

3. Improve network performance: Switches store and forward data to avoid conflicts and improve network performance and efficiency.

4. Network segmentation: The IS420ESWBH3AX switch can split the network into multiple virtual local area networks (vlans), limiting the broadcast domain and enhancing the security and manageability of the network.

5. Bandwidth management: The switch can provide QoS (quality of service) functions to prioritize different types of data traffic and ensure that critical applications get the required bandwidth.

In short, IS420ESWBH3AX switches are one of the basic components of building modern computer networks, which can effectively manage and optimize network traffic and improve network performance, reliability and security.
