Antminer S17/ S17 Pro / S17 / T17/ T17 / T17e miner retrofit heatsink no more repeated replacement BM1397AG Why do Antminer S17 series miners need to change the heat sink (what is the pain point)? S17 series miners drop the heat sink leading to a short circuit, burning the board and scrapping it, causing losses. Changing the chip does not solve the root of the problem, chip shortage, high maintenance costsUsed miners are far below market price, and often damaged in transit. Our advantages in similar products. 1, 1-year time N times to improve, a long time to verify2, first-class heat dissipation and insulation (performance resistance to fight not afraid than)3, We had improved 30,000 + machines4, We have a stable supply chain that can support a large number of orders in a short period of time Why us? We have made several improvements to the product within 6 months. After completion, we have modified 30,000+ S17 (series of mining machines) in China in the past 2 months We have a stable supply chain for this product that can support a large number of orders in a short period of time.

Audiovisual over Internet Protocol (AV over IP) is an Internet Protocol-based audio and video transmission technology that transmits audio and video data over standard networks! AV over IP products has seen triple-digit growth in the past three years and will grow at a compound annual growth rate of 60% in the next five years. AV over IP is a game between image quality, bandwidth, and latency in specific applications. The AV industry has found the next best way to transmit audio and video signals, with IP providing a standardized architecture. But today, the way it is transmitted on the architecture no longer meets the needs of various customers, and we need to determine what image quality, bandwidth, and latency to allow based on the application. And because of this, in the face of various audio and video transmission protocols and trends, we need to distinguish precisely what is appropriate for the project’s needs! ST 2110 SMPTE —Rolls-Royce in the broadcaster level – SMPTEST 2110 is a standard defined by the Society of Motion Picture and Television Engineers – SMPTEST 2110-10/20/30: Effective audio and video without compression – SMPTEST 2110-21: Traffic shaping and transmission timing – SMPTEST 2110-31: Real-time transmission of AES3 signals based on RTP – SMPTEST 2110-40: Auxiliary Packet Imaging as Real-Time Transport Protocol Packets – SMPTE is aligned with global associations and supported by AIMS, AES, EBU, VSF, IABM, and MNA – Based on 10Gbps network transmission, uncompressed, high bandwidth, low latency – High build-out cost SDVOE —Standardized

Replace the control board for your ASIC miner is very simple, just follow below steps and you will also be a repair engineer. ( Put on gloves on your hands will be safer.) 1. Remove the ASIC Fans from the miner , took off the fan cable from the control board. 2. Remove the cable between control board and hash board. 3. Take out the hashboard and clean the board, make sure the heat sink stick well on the hash board. 4. Take out the broken control board and replace the new board, make sure the led light and plan ports fits well with the miner shell. 5. Connect all the cables well and assemble the fans well. If All done well and connect the power to test the miner. The below video shows one of the professional Computer engineer’s operations for your reference.

Antminer Power supply Common Troubleshooting Fan don’t work, no 12V output Reason:The power supply on the AC side  is abnormal Ways to deal with 1.Check the AC side if the connector connect tightly 2.Check whether the grid has power and the voltage is normal Fan work normally, no 12V Output Reason: 1.low grid voltage ,2.power protection Ways to deal with 1.Use a multimeter to confirm that the current voltage is above 250V, so as to ensure that the power supply can be turned on 100% 2.Check if the power supply has output or overload. This situation will cause the power supply to enter the lock-up protection state. It can be restored after removing the fault and restarting the power supply. After the power supply stops outputting for a few seconds, it resumes normal working, and continues to work for a few minutes and then stops outputting, trouble happens repeatedly Reason: The power supply has entered the over-temperature protection Ways to deal with 1.Check if the fan work normally2.Check whether the cooling air channel of the power supply is blocked3.Check whether the power supply has been used for a long time and there is too much dust accumulated inside4.Check the voltage used by the power supply or the surrounding temperature exceeds the value of the power supply power setting curve Miner output normally, but fan didn’t work Reson: Fan broken Ways to deal with 1.Check if the fan is blocked by other things2.fan is broken A normally working power supply suddenly

During the process of shipping for those heavy ASIC Miners, there will be some damage to miners, like problems with Fans/PSU/Hash boards/Control boards because international logistics would not take good care of the heavy items. Meanwhile, the miner will stop working after working for a long time. For Hash boards and Control boards, we could support free repairs if you don’t mind affording the Round-trip shipping. For Used miners, we strongly suggest that it’d purchase extra spare parts like Fans/PSU as preparation for exchanges because they usually get damaged during the long trip shipping easily. We offer full series of ASIC Miner’s parts, like Antminers Parts, Whatsminer Parts, Avalon Parts, Innosilicon Parts, and Goldshell KD Box parts. Among those parts, we have basic chips, hash board, fans, power supply, power cord cable, capacitor, control board. Regarding to the repair tools, We have Antminer test fixture, Tin tool sets, hash board code editor, universal chip fixture , Portable desoldering gun, Headband Magnifier,oscilloscope, Electronic magnifier, ANLIXIN-862D desoldering station,205H high-frequency soldering station, DDR5 DDR5X DDR6 combination Tin Tools, etc. We also offer programs like L3+ Tester Production File, universal Antminer test fixture TF card programs, and Antminer hash board PIC file. If you have mining farm, we can offer you Combined shelf, Negative pressure fan, Power socket module, Mobile miner box, ASIC miner external water cooling radiator fan, Miner water cooling water pump.

Doing business is something that requires mental and physical strength.The continuation of the company relies on the accumulation of the past,the accumulation of time consumed is not infinite. Some companies are flow thinking, some are product thinking. We temporarily belong to the latter, the former latter is not superior or inferior, past thinking confined to the latter, did not think about the former, the two do not conflict, future growth comes from the new organization of the former, as well as the continued maintenance of the latter. The mission and values of the company are extremely important when the company enters the mid-term. The mission needs to be deeply understood and believed in by the founder, it is the compass of the company, the key guiding factor of the second, third…n curve, and is a great challenge for the founder. Both of these are very difficult and very important, and are long-term projects.
