交换机  EDS-408A-MM-SC  可以将网络扩展到更多的设备上

二层网管型交换机

Moxa 二层网管型交换机具备工业级可靠度、网络冗余功能，安全特性符合 IEC 62443 标准。我们强化产品设计，以满足特定行业需求，符合多种行业认证，例如轨道应用的 EN 50155 标准相关的部分要求、电力自动化系统的 IEC 61850-3 标准、智能运输系统的 NEMA TS2等。

交换机（Switch）是一种网络设备，用于在计算机网络中连接多个设备并在它们之间传输数据。它是一种多端口设备，可以将多个设备连接到同一个网络中，并实现它们之间的通信。

EDS-408A-MM-SC 交换机的主要功能是根据网络中设备的 MAC 地址（媒体访问控制地址）进行数据转发。当交换机接收到一个数据帧时，它会检查数据帧的目标 MAC 地址，并将其转发到相应的端口上。这样，只有目标设备能够接收和处理该数据帧，从而提高了网络的效率和安全性。

EDS-408A-MM-SC 交换机还可以提供网络的扩展和冗余。通过添加更多的交换机和端口，可以将网络扩展到更多的设备上。同时，如果一个交换机或端口出现故障，其他交换机可以接管其工作，从而保证网络的可靠性。

EDS-408A-MM-SC交换机通常用于企业、学校、政府机构等大型网络中，以提供高速、可靠的网络连接。它可以根据不同的需求选择不同的类型，如以太网交换机、光纤交换机、无线交换机等。

总之，交换机是一种用于在计算机网络中连接多个设备并在它们之间传输数据的重要设备，它为网络的扩展和可靠性提供了保障。

Layer 2 NMS switch

Moxa Layer 2 managed switches offer industrial-grade reliability, network redundancy and IEC 62443 compliant security features. We strengthen our product design to meet specific industry needs and meet a variety of industry certifications, such as EN 50155 for rail applications, IEC 61850-3 for power automation systems, NEMA TS2 for intelligent transportation systems, and more.

A Switch is a network device used to connect multiple devices in a computer network and transfer data between them. It is a multi-port device that can connect multiple devices to the same network and achieve communication between them.

The main function of the EDS-408A-MM-SC switch is to forward data based on the MAC address (media access control address) of the device in the network. When the switch receives a data frame, it checks the target MAC address of the data frame and forwards it to the appropriate port. In this way, only the target device can receive and process the data frame, thus improving the efficiency and security of the network.

The EDS-408A-MM-SC switch can also provide network expansion and redundancy. By adding more switches and ports, you can extend the network to more devices. At the same time, if one switch or port fails, other switches can take over its work, thus ensuring network reliability.

EDS-408A-MM-SC switches are commonly used in large networks such as businesses, schools, and government agencies to provide high-speed, reliable network connectivity. It can choose different types according to different needs, such as Ethernet switch, Fibre Channel switch, wireless switch and so on.

In short, a switch is an important device used to connect multiple devices in a computer network and transfer data between them, which provides a guarantee for the expansion and reliability of the network.
