The ring network switch works at the data link layer, with a high-bandwidth back bus and internal switching matrix. After the control circuit receives the data packet, the processing port looks up the address reference table in the memory to determine which po...

Switches are classified into managed switches and unmanaged switches according to whether they can be managed or not. Managed switches can be managed through the following methods: management through RS-232 serial port (or parallel port), management through we...

The serial port server provides the serial port to network function, so that the serial port device can immediately have the TCP/IP network interface function, connect to the network for data communication, greatly expand the communication distance of the seri...

The protection level of industrial switches is often referred to as the IP protection index. IP refers to "ingress protection, access protection", and the protection level is drafted by the IEC (International Electrotechnical Association). So, when we are purc...

As we all know, one of the major advantages of PoE power supply is energy saving, but where does energy saving manifest itself? The PoE switch will automatically adjust the power according to the power supply device. For example, when the temperature of an inf...

1. Insufficient power, the receiving end can't move: 802.3af standard (PoE) output power is less than 15.4W, which is sufficient for general IPC, but for high-power front-end equipment such as dome cameras, the output power cannot reach To request. 2. Risk is ...

Nowadays, with the development of society, many companies have higher and higher requirements on the network, more and more complex systems, many old lines need to be upgraded and upgraded, and the requirements on industrial switches are getting higher and hig...

The specific introduction of the fiber media converter  indicator: The fiber media converter  has a total of 6 lights, two columns of vertical lights, the three lights near the patch cord are the indicator lights for the fiber, and the 3 lights near the ne...

A network switch is a device that expands the network and can provide more connection ports in the sub-network to connect more computers. It has the characteristics of high performance-price ratio, high flexibility, relatively simple, and easy to implement. So...

Industrial  Ethernet switches are placed on the back of the router to expand the router interface to solve the problem of insufficient interfaces. When Ethernet is designed, due to its use of Carrier Sense Multiplexing Collision Detection (CSMA/CD mechanism),...
