Possible vswitch Problems

As a very important part of network equipment, the stability of a switch is an important part of maintaining network stability. Therefore, when selecting a vswitch, we must carefully consider the stable performance of the vswitch. In fact, if the switch is unstable and fails, we will not call the following situations. Next we will use the tengda switch to perform a basic anatomy of these situations.

1. Power Supply Fault

If the POWER supply fails, the fan of The TENDA switch does not turn around and the POWER light does not turn on after the switch is enabled after the plug and POWER cord are eliminated. Basically, the vswitch has no response! In this case, we basically decided that there was a problem with the power supply. This problem is generally caused by the aging of the power supply line or lightning strikes. It may also be caused by unstable power supply voltage. If this problem occurs, you can change the power supply.

2. circuit board faults

Some computers in the LAN may not be able to access the server. It is not a NIC or wiring problem discovered through tests. These computers are always good or bad. After a long time, A group of related computers cannot access the Internet. At the same time, they also find that all the connection indicators of the vswitches connected to this group of computers are flashing irregularly.

Generally, the tengda switch is composed of the main circuit board and the power supply circuit board. The fault is caused by two problems. The main causes of the failure of the circuit board are: the components on the circuit board are damaged. These problems usually occur, and the best way is to repair the factory!
3. Port faults

The entire network operates normally, but some machines cannot communicate normally. This is a common problem in the use of vswitches. Because some ports are not plugged in or are dirty, it is easy to have local ports not connected to the network. Of course, there are some other improper use methods, which directly causes the saving of a port. Therefore, it is best for everyone to keep the place clean and sanitary when using the tengda switch. At the same time, we should try our best to standardize the operation so that the service life of the switch will be longer.
4. Backboard fault

The external power supply environment is normal, but each internal module of the switch cannot work normally. Each module of the vswitch is connected to the backboard. If the vswitch works in a humid environment, the circuit board is short-circuited by the tide, or the components are damaged by high temperature and lightning strikes, in these cases, the circuit board is faulty and cannot work properly.

5. Improper configuration

After connecting a workstation to several ports on the switch, you cannot Ping other computers in the LAN, but the "local connection" icon on the desktop still shows network connectivity. This is also a very common low-level problem. We basically follow the tengda switch specification for configuration, basically there is no problem.
6. virus attacks

Suspicious traffic can be detected, and a single host sends a connection request that exceeds the normal number. This abnormal large amount of traffic is often a sign of worms or network abuse, and finally causes the network to crash! Viruses are common and dangerous in the Internet. Its attack is the most complex network problem! Therefore, when using the tengda switch, you should pay attention to virus awareness and try to reject viruses as much as possible.

7. System Data Error

Full load, packet loss, and wrong packets may occur on switches, which may even cause all-round system faults and affect LAN communication. Due to various design reasons, there are some vulnerabilities. Under certain conditions, these vulnerabilities may cause system data errors. These are basically problems that occur in every manufacturer. Therefore, you should pay attention to the latest upgrade package on the official website of tengda and upgrade your software at any time.

The failure of the switch should be hard to list. The key is that we should do a good job in daily maintenance, keep various records, and keep the switch in a proper working environment. Combined with relevant experience, minimize faults. Tengda vswitch has always been striving for excellence. Therefore, our products are constantly improved and optimized. We firmly believe that we can speak stably.
