How to tell if the switch is broken

- Jul 31, 2019-

In the age of information network, no matter in company, family or public place, it is surrounded by network information all the time. It must be familiar with the terminology of special equipment used in the process of network transmission, such as cat, router, network line and switch.


A switch is a device that transmits information to the required router separately to complete a connection of signals. There are usually many ports on the switch, which can connect several local area networks. As an electronic product, the switch always has some big and small problems because of improper operation or long-term use. What switch problems do we often encounter in our life?


A common phenomenon is that after switching on the switch, the switch does not work and the light is not on. At this time, we need to look at the power supply. After ensuring that the power supply line or the outlet power supply is all right, the switch still has the above situation, which may be caused by the power supply line of the switch is not open or the voltage is unstable. At this time, we need to replace the power supply of the switch. Another kind of situation is often encountered, in the process of Internet access, suddenly the computer shows that the server can not be accessed, whether it is re-plugged in the network or restart the computer, there is no way to continue Internet access, after a period of time, the switch's indicator lights start to flicker, this situation occurs, generally is handed in. There is a problem with the main board of the switch. It may be that the components in the circuit board of the switch are damaged. The best way is to inspect the place where the switch is repaired. If the switch is damaged, it needs to be repaired in the factory.


Another case is that when a switch connects to several computers, only one of them can't connect to the Internet properly. At this time, we should check the corresponding ports of the computer connection to see if it is blocked by dust or dirty things or not plugged in properly. We just need to clean the switch in time and insert it again. However, it can not be ruled out that one of the ports is damaged due to improper operation in the process of operation. Therefore, correct operation is conducive to extending the service life of the switch.


Sometimes the circuit board of the switch will be damped in the humid environment, or the normal operation of the switch will be affected by too high temperature. Sometimes because of ignorance, the switch is connected to the computer configuration inconsistent. Although the switch works normally, the computer still can not access the Internet properly. Therefore, when installing the switch for the first time, it should strictly follow the operation instructions.
