How to troubleshoot the fault of the miner?

How to troubleshoot the fault of the miner?

If a miner fails, the problem may be in the network, pool, firmware, control board, hash board, etc., so to determine the exact cause of the problem, you can do the following:

·Check the data cable connection: 

Check whether all the data cables on the miner are plugged in tightly. Specifically, the three data wires connect to the hash board (and the fan's data wire). They may come loose during transport.

·Check the connection of the PSU:

Check that the power supply is connected correctly. Ensure all 6PIN data cables of the power supply are plugged into the miner tightly.
Some mining machines have their integrated power supply, such as Antminer S15, Antminer D5, etc. Please check whether the connecting copper bars on the miner are firmly inserted.

·Check network connection: 

Check your home network, mining pool, make sure all networks are working well.

·Check other devices on the network: 

Check if other devices in the background take your miner's IP address? Try unplugging all other devices in the network (e.g., if you have multiple other miners) to run only this miner.
Or change Internet Explorer ​when trying to log into the miner's configuration page.

·Replacing the network for the miner:

Try changing the miner's router or moving the miner to another place.
Switch to another pool.

·Check the miner:

Shake the miner lightly and see if you hear the radiator or parts falling.

·Check the PSU:

Is your PSU working fine? If you bought an Antminer 1600w PSU (APW3-12-1600-B2) for the miner, please ensure the voltage is stable. The working voltage of this power supply should be >= 205V (for Antminer APW3++ power supply, the working voltage is 110V-220V, that is, 200V-240V is 1600W, and 100V-140V is 1200W). If your voltage is unstable, the PSU may stop working (or only the fans work and no power output).

·Replace the data cable:

Generally, there are three data cables on the miner, which respectively connect the three hash boards to the control board. Replace these cables and see if that fixes the problem.

·Replace the control board:

Remove the control board from a working miner and use it on a non-working miner to see if everything works. On the top of the miner, there is a silver cover that is screwed on, and the control board is inside:
Antminer S5/S7: There is a black block on top of the green board; you should swap the whole part (green board + black block);
Antminer S9/T9/R4: There is only one green board, which is the control board;
the control board of-Antminer S9
the control board of-Antminer R4
Take out the screw on the silver cover, remove it, and check whether the control board is loose. If it is loose, it is recommended to replace it with a new control board for debugging.

·Determining Hash Board Failure:

Disconnect the data cable connecting the hash boards and run only one hash board at a time. This is to determine if each hash board works independently.

What is the Antminer BM1489 ASIC chip?

What is the Antminer BM1489 ASIC c hip? Antminer  BM1489 ASIC chip is an ASIC chip on the Bitmain Antminer L7 hash board for mining Litecoin and Dogecoin. In the integrated circuit industry, an ASIC is considered an integrated circuit designed for a specific purpose. The characteristic of ASIC is to design and manufacture special integrated circuits according to user requirements. The chips used for mining are called ASIC miner chips. Compared with general-purpose integrated circuits, ASICs have the advantages of smaller size, lower power consumption, improved reliability, improved performance, enhanced confidentiality, and reduced mass production costs. In terms of mining hash rate, ASICs are tens of thousands of times or higher than contemporary CPUs and GPUs, so ASIC chips on the market are also more popular than them.

How to use Antminer BM1387 tin tool to replace damaged chips?

How to use Antminer BM1387 tin tool to replace damaged chips? In the repair work of the h ash board, the most common problem is to replace the ASIC chip, which  is the most easily damaged part of the h ash board. In this article, I will use A ntminer as an example to show my friends how to use Antminer BM1387  tin tools to replace damaged chips?  Although there are many chip models, most of the pin positions and sizes are the same. ASIC chips are usually small in size and the pins are arranged closely, which brings great difficulty to maintenance and replacement. Because when replacing a new ASIC chip, it is necessary to accurately apply solder paste on each tiny pin, then heat it to melt, and finally fix it on the h ash board. For how to solve this problem, after various attempts, we finally chose a convenient and efficient way: making professional tin tools (ASIC tin tools). Its principle is to fix the chip on the base, then use a special steel mesh to align the pins of the chip, and

How long is the life of a miner?

How long is the life of a miner? Participating in mining is one of the important ways to enter the blockchain industry and enjoy industry dividends. Moreover, mining is more stable and more suitable for large institutions and significant funds to enter the market than buying currency. Mining is a highly specialized thing. Therefore, many new miners will face many problems before entering the market, such as: What are the ways to participate in mining? How to select miners scientifically? Is it more cost-effective to buy new miners or to buy used miners? Today, we will solve a problem many new miners may encounter before entering the market: How long can the purchased miners dig coins? In other words, how long is the life span of miners? 1. The physical life of the miner The life span of a miner can be divided into the "physical life" and "economic life". The physical life of a miner refers to the time from the time the miner is put into use in a brand new state unti

How to check and repair the hash board resistance?

How to check and repair the hash board resistance? After some fixed resistors are open or their resistance increases, their surface will have apparent changes such as cracks, pins disconnect, or blackened color. At this time, we can use an intuitive check to confirm whether they are good or bad.  If the appearance of the suspected resistor is normal, you need to test it with a multimeter to determine whether it is normal. Measuring resistance with a multimeter is divided into two methods: in-circuit detection and non-in-circuit detection. In-circuit detection is to directly measure the resistance of the suspected resistance on the circuit board to determine whether it is consistent with the nominal value. Non-in-circuit measurement is to measure the resistance after removing the resistance from the circuit board or suspending a pin. 1. Detect fixed-resistance (1) First, write down the nominal value. If it is a color ring resistor, first find out its resistance value according to the co
