Of course, when upgrading the system, errors may occur.

In fact, switches are sometimes referred to as multiport bridges.Д«, TFTP, etc. The switch maintenance switch has multiple ports, each of which has a bridge function to connect to a LAN or a high-performance server or workstation.

S, Linux, because of the design reasons at the time, there are some loopholes, when the conditions are right, it will lead to the switch full load, packet loss, wrong package and so on.

Inside the switch is a refreshable read-only memory that holds the software system necessary for the switch. The switch system is a combination of hardware and software. The construction of anti-electromagnetic interference and anti-static environment provides a good environment for the normal operation of network equipment.) Software failure of the network switch 1.System error Therefore, when building the equipment room, we must first do lightning protection grounding, power supply, indoor temperature, and indoor humidity. (We have learned from the above that the hardware problems of the switch are often caused by poor computer room environment, which can easily lead to various hardware failures. The wrong line connection leads to the network loop.

The two fibers in the cable are connected in an interlaced manner. When the cable is connected, the crossover cable should be used but the direct connection is used. The cable is arranged in the wrong order or not standard. In fact, this type of fault is theoretically not a fault of the switch itself, but in actual use, cable faults often cause the switch system or port to fail to work properly, so this type of fault is also classified as a switch hardware failure.ДЇor example, the connector is not tightly connected. The only way is to replace the backplane. Even if it is an electrical maintenance engineer, there is no way to do it.

In the case of the normal power supply of the external power supply, if the internal modules of the switch are not working properly, it may be that the backplane is broken. If the environment is wet, the board is short-circuited by moisture, or the components are damaged due to high temperature, lightning strikes, etc., the board will not work properly.ДЇor example, if the heat dissipation performance is not good or the ambient temperature is too high, the temperature inside the machine rises, and the components are burned out.

There are a lot of professional companies doing lightning protection projects, and you can consider them when implementing network cabling.Д®ach module of the switch is plugged into the backplane. Set professional lightning protection measures in the equipment room to avoid damage to the switch caused by lightning. Some UPSs provide voltage regulation functions, while others do not. If conditions permit, you can add UPHOTOSHOP to ensure the normal power supply of the switch. The independent power supply is usually introduced to provide independent power supply, and a voltage regulator is added to avoid instantaneous high voltage or low voltage. For such faults, the external power supply should be done first. Such problems are easy to find, easy to solve, and most preventable. If the POWER indicator on the panel is green, it means normal if the indicator is off, the switch is not working properly. Other common telephone voice switches, fiber switches, and so on.Дamage to other components in the machine due to the power supply also occurs frequently. The most common switch is an Ethernet switch. It provides an exclusive electrical signal path for any two network nodes that access the switch. The switch maintenance switch means вЂњswitchвЂќ is a network device used for electrical signal forwarding. The external power supply is unstable, or the power supply line is damaged or the power supply is damaged due to aging or lightning strikes. Here we collect 5 common hardware issue of network switch: power failure, port failure, module failure, backplane failure, and cable failure.
