It is shared by the mining machine hosting network (58kuangji. com). As we all know, mining needs to connect to the network to occupy bandwidth for mining operations. Network problems range from small network fluctuations that affect mining revenue to large ones that cause the mining machine to enter the shutdown protection state, affecting its service life. Therefore, the operation and maintenance of the mine should be very careful in network maintenance. This article will discuss the problem of network disconnection encountered in the mine and how to maintain the network.

1、 How to maintain the mine network?

1. The mine operation and maintenance needs to be familiar with the connection method of the network segment and emergency network segment at each rack position. In case of any abnormality, it can be switched in time, and the cause can be investigated to ensure the independent power supply of the switch. This is also the guarantee of fast reconnection in case of network interruption.

2. Regularly check whether the backup broadband network is normal, separate the mining network from the living network, avoid unnecessary use of network speed, ensure the connection stability between the mining machine and the ore pool, and avoid the fluctuation of hash rate. If necessary, you need to limit the IP speed of the living area and deny access to unknown websites.

3. It is necessary to regularly check whether the network delay between the mining machine and the connected mining pool is stable. Once the delay is greater than 100 milliseconds, the internal and external networks must be checked. The internal LAN needs to check whether the network equipment is faulty, and the external network needs the broadband operator to check the equipment lines.

4. The temperature of the network device needs to be checked. In some cases, it is necessary to consider installing fans for heat dissipation, and avoid placing network equipment and network cables in the warm air outlet of the mining machine, because the CPU temperature of the network equipment is too high, which will affect the stability, or even lead to a crash.

Of course, the above four points can only play the role of "prevention", trying to nip the symptom of network disconnection in the cradle. Therefore, when the quarry is disconnected from the network, another set of operations is required.

2、 Common causes of disconnection

There are three common disconnection situations: rack disconnection, layered disconnection and equipment disconnection.

1. When the rack is disconnected from the network, the server flashes red, or the running light is always on, and it is in a panic state. The reasons can be roughly divided into the following:

1) Switch off, restore power supply and repair network;

2) The network port of the switch is damaged, and the network port of the main network cable on the switch needs to be replaced;

3) If the switch is faulty, check the switch layer by layer and replace the switch;

4) If none of the above conditions are true, it can be determined that the main network cable is faulty, and the network cable connector or the entire network cable can be replaced.

2. In case of layered disconnection, the fault is similar to rack disconnection. The server flashes red, or the running light is always on and is in a panic state.

Common fault causes are divided into three points:

1) Power off the corresponding switch, restore power supply and repair the network;

2) If the connecting cable between the two switches is faulty, replace the network cable;

3) If the switch fails, it needs to be replaced. This requires first checking for power failures and network conditions.

3. The factory is disconnected, the factory is disconnected, all equipment is abnormal, and the server crashes. Compared with the first two cases of network disconnection, the probability of plant network disconnection is lower, but the impact is the most serious, so special attention should be paid. In case of failure, it is necessary to check whether the polymerization switch is powered off and whether the photoelectric converter is powered off; At the same time, it is suggested that the photoelectric converter and the converging switch establish circuit and network dual route protection measures.

summary

The above contents respectively introduce the network maintenance of the mine and the common reasons for network disconnection. In addition to several breakages mentioned in the article, various unexpected breakages will be encountered in the actual operation and maintenance process. Therefore, the operation and maintenance team needs to adjust measures to local conditions, analyze and answer the actual situation, and strive to complete the network repair in the shortest time to ensure that the hash rate income is stable at a high level.
