In the process of manufacturing and using the miner, if the user encounters chain loss, low hashrate, multiple hardware errors, etc., please refer to this manual for test and maintenance.
Note: This manual cannot cover all possible abnormal problems. If you encounter a problem that cannot be solved using this manual, please consult our relevant personnel, and they will update this manual when necessary.
Ⅰ. Overview
1. The circuit layout of the hash board and the distribution of test points
Take 3*31 model as an example. For other models, please refer to relevant design documents.
(1) The three adjacent chips in the figure are a voltage domain [(1,2,3), (4,5,6). (91,92,93)]. There are a total of 31 voltage domains on this hash board, and the voltages of the three chips in each voltage domain are the same, and the average voltage of each voltage domain is about 0.45V at startup (T series machines)
(2) The red arrow in the figure shows the transmission direction of CLK and communication signals;
(3) There are 1 to 7 test points between each two chips (each model is different, please refer to the design file for details); test points 1 to 7 are CLK, RST, EN, SCK, CS, DI and DO signals respectively. Specifically as shown below:
(4) Test points and connections between adjacent chips:
2. Description of the test software
After SMT, before sticking heat sink
It is used to quickly check soldering problems. It does not do a long time function test, but only tests whether the transmission of all chips is normal.
After pasting the heat sink on the non-chip side
It is used to check various faults of the single board in the high power state as early as possible. Due to the lack of a heat sink, the operating frequency of the chip is lower than that of normal use.
Binning after pasting
After all heat sinks are pasted
The test is carried out under 4 kinds of working voltages, and the boards are graded according to the measured hash rate. Boards of the same grade are loaded into a machine.
Locating problems with a single hash board
The program will send communication commands indefinitely for maintenance personnel to use multimeters and oscilloscopes to check the necessary circuits.
The machine is aged before leaving the factory
Use the official factory firmware, if there is an exception, an error code will be displayed on the mass production management interface.
3. Error code list of test software before and after pasting
If no problem is detected, "√" will be printed at the end of the log, otherwise it will be printed "×"。 When a problem is detected, the software will report the error type with the highest priority. The order of error priority is: E0>E9>E6>E4>E7>E5>
E3 > E1 > E2 > E8. The chip can be repaired or replaced according to the report.

2. Establish a test environment
Take out the control board of the miner to be tested, place the control board and the serial port board as shown in the figure, insert the TF card, and insert the jumper cap into the J2 interface. Connect the serial port board and the computer with a data cable.
III. Maintenance process
1. The basic process of repairing the aging of the whole miner
(1) Reproduce the bad aging problem and record the error code. If you need our company's research and development analysis, you also need to save the aging log.
(2) Check whether the power output corresponding to the defective board is normal.
(3) If it is a multi-channel control power supply, exchange the power channel of the bad board and the normal board (note that the order of the data line interface is adjusted at the same time), and then observe whether the bad phenomenon follows the hash board or the power supply. If it follows the power supply, replace the power supply again. do aging.
(4) Disconnect the power supply and network cable. Check whether the appearance of the machine is damaged. Check whether the power and data cables are loose or disconnected.
(5) Use the original machine power supply and the faulty hash board to do a sticky test in the bucket, and record the error code and log. If there is no abnormality after 5 consecutive tests, our R&D personnel will be notified for analysis.
(6) Use the original machine power supply and the faulty hash board, and do a post-stick test outside the barrel to see if the phenomenon still exists and make a record. If the chip surface is a heat sink fixed by screws, remove the heat sink on the chip surface, and then do a pre-stick test to see if the phenomenon still exists, and make a record.
(7) Continue to analyze in accordance with the faulty board repair process.
2. The basic process of repairing the single board
Before maintenance, please confirm that the power supply, control board, and various cables are connected properly.
(1) Use the pre-glue test software to test and get the error code Ex:x. Different next steps may be taken for different types of errors.
(2) Check the appearance of the board, and observe whether there are missing components, errors, or abnormal appearance. Check whether there are solder balls, foreign objects, etc. near the error chip.
(3) Run the maintenance procedure and check the input voltage with a multimeter. Check crystal oscillator supply. Check tail IO boost circuit. Check the LDO output of each stage.
(4) Use an oscilloscope to check the chip input and output signals CLK, SCK, DO, DI, CS, RSTN, START.
(5) If the output signal of the ASIC chip is found to be abnormal, do not easily replace the chip. According to the instructions in the following chapters, first try methods such as adding soldering, re-soldering, and swapping with other chips on this board.
(6) If the method of chip exchange is adopted, it can be observed whether the problem follows the chip.
(7) If the above method is invalid, then replace the chip. It is necessary to record in detail the specified information such as the cause of the problem of the removed chip in the maintenance report. Regularly send the maintenance report to our company for analysis.
3. Locate the broken chain with a maintenance-specific program
Copy the provided repair.bin to the TF card and plug it into the serial board. Connect power and data cables (no fan required), power on. According to the error message of the software before or after gluing, detect the test points of the relevant chip and its adjacent chips.
Description of function keys and indicators in the service software.
(1) After power on, the lights on the control board are on (red and green lights next to the reset button). If the power-on link is broken, the software will keep sending cmd04. After pressing the function key next to the USB card slot, the software will stop sending cmd04, and the program will continue to run, and the green light will be off at this time;
(2) If the power-on link is connected, the software will continue to send cmd04. Similarly, after pressing the function key, it will stop sending cmd04, and then the green light will go out;
(3) After the frequency configuration fails, the software will send cmd04 at the point of failure, press the function key, stop sending cmd04, the program continues to run, and the red light is off at this time;
(4) After the frequency configuration is successful, if the link breaks during the continuous reading process, the software will send cmd04 at the link break. After pressing the function key, the transmission will stop, and the red light will be off at the same time, and the program will continue to execute.
IV. Analysis of typical problems
1. E0: 1
This kind of problem is that the communication chain is completely broken, and most of them are caused by abnormal peripheral circuits. Known causes are:
(1) The power supply has no output or the output is abnormal.
(2) The solder connection between the communication interface and the plug-in pin is shorted.
(3) The data cable is not plugged in properly or the contact is poor or damaged, resulting in a short circuit.
(4) The components between the communication interface and the first chip have problems such as false soldering, short circuit, burning, displacement, and missing parts.
(5) The IO of the first chip was damaged by static electricity.
(6) The crystal oscillator is abnormal.
(7) Some components are missing.
If you encounter such problems, you need to follow the "5 Checklist" for a complete inspection.
2. E0: N
The problem is that part of the communication link is broken, and it is broken at the Nth chip. Known causes are:
(1) The signal between the Nth and N-1th ASIC chips is abnormal, the pins of the two chips are falsely soldered, floating high, short-circuited, and IO is damaged.
(2) False soldering, short circuit, burning, displacement, missing parts and other problems occur in the peripheral components of the Nth chip.
Repair steps:
(1) Check the peripheral circuit, if there is no abnormality, go to the next step.
(2) Check the ground resistance of the IO of the Nth ASIC chip and the front and rear ASIC chips. If there is no abnormality, proceed to the next step. If there is any abnormality, remove the chip and compare it with the ground resistance of the IO of the new chip. If there is no obvious difference, go to the next step, otherwise replace the chip.
(3) Re-solder the Nth and N-1th chips, if there is still an abnormality, go to the next step.
(4) In other cases, it is necessary to use a maintenance-specific program to assist in positioning. Check the chip when software executes to "Start to send cmd04 endlessly". At this time, you need to use a multimeter to measure the voltage of the abnormal chip (the measurement method is as shown in the figure below). And use an oscilloscope to measure the signals of the Nth chip and the N-1th chip. As shown in Figure 14, if the DO/CS/SCK output by the N-1 chip is abnormal (it can be compared with the normal waveform of the chip before the N-1th chip, if the waveform is inconsistent, it is abnormal), then replace the N- 1 chip. If the output of the Nth chip is abnormal, replace the Nth chip. If the output of the Nth chip is normal, but the input DI is abnormal, then replace the N+1th chip.
3. E6: N
The voltage of the Nth chip is abnormal.
(1) Use a multimeter to confirm whether the voltage of the chip is abnormal. If the voltage of the chip is too low, detect the SCK signal of the test points of the three chips of this level, and compare the chip with the SCK frequency jitter with other chips of different levels with higher voltage division. Swap. If the SCK signals are normal, replace chip N with other chips of different levels with higher voltage division.
(2) If the problem is with the chip, replace the chip.
4. E7: 0
When E7:0 appears, you need to use maintenance software to locate the problem location, the location method is the same as E0, and test when the program runs to "CRITICAL PLL CONFIGURE ERROR on Board 0 . Begin to Check SPI . "
5. E7: N
Indicates that the chip N does not respond, and you need to replace the chip. The checking method is the same as E0:N.
6. E1: N
The Nth chip lacks a core. If this problem occurs in a large area, submit it to our company for research and development analysis. If only a few hash boards have such problems, replace chip N.
7. E2
The total number of cores on the board is insufficient. At this time, it is necessary to check whether the total voltage of the circuit board is abnormal (refer to the method in E0 error), and if there is no abnormality, it needs to be returned to the factory for repair.
8. E3: N
The softbist error rate of the Nth chip is high. The method is the same as E1:N.
9. E4: N
The pll of the Nth chip is not locked. Check the output CLK of the N-1th chip. If there is no abnormality, resolder the N-1th and Nth chips. If it still can't be solved, replace the Nth chip.
10. E5: N
The temperature of the Nth chip exceeds the standard, replace the chip. If the problem occurs over a large area, you need to check the heat sink. If the problem still cannot be solved, it needs to be returned to the factory.
11. E8
The temperature of the Nth chip exceeds the standard, replace the chip. If the problem occurs over a large area, you need to check the heat sink. If the problem still cannot be solved, it needs to be returned to the factory.
The softbist error rate of the whole board is high, you need to check whether the board voltage and the clock of each chip are abnormal. If abnormal, replace the abnormal chip
If there is no abnormality, it needs to be returned to the factory.。
Ⅴ. Checklist

ПОЛЕЗНОЕ ПРО АВАЛОНЫ
Бренд Innosilicon – один из самых старых на рынке оборудования для добычи криптовалют. Компания была основана ещё в 2006 году. Однако изначально она разрабатывала и производила проводники для других брендов.
Только в первой половине 2010-х годов Innosilicon начала выпускать оборудование для добычи криптовалют. Изначально это были хэш-чипы и отдельные платы. Собственные майнеры появились у бренда позже – во второй половине 2010-х годов. Но при этом компания не специализировалась исключительно на ASIC’ах, продолжая выпускать и другие технологические решения. Например, в 2019 году она принимала участие в разработке стандарта HDMI 2.1 IP, который сегодня используется, например, в PlayStation 5.
Такой многонаправленный подход открывает Innosilicon доступ к наиболее современным технологическим решениям от других производителей – и компания использует это при разработке ASIC-майнеров.
Именно поэтому Innosilicon не ограничивается выпуском майнеров на SHA-256, криптографическом протоколе Bitcoin. Хотя в настоящее время бренд – единственный в Китае, который оснащает свои ASIC’и 5-нанометровыми чипами Samsung и TSMC. Эта архитектура обеспечивает высокую производительность при сохранении адекватного энергопотребления и – главное – низкого тепловыделения.
За годы существования Innosilicon создавала продукты для таких технологических гигантов, как Microsoft, Google, AMD, Microchip, Synaptics и других компаний.
В настоящее время ассортимент ASIC-майнеров бренда Innosilicon включает несколько моделей, ориентированных на использование с различными криптовалютными алгоритмами шифрования:
- SHA-256 (Bitcoin, Bitcoin Cash, Litecoin Cash, Peercoin, Myriad и другие);
- Ethash (Ethereum, Callisto Network, Metaverse ETP и другие);
- Scrypt (Dogecoin, Litecoin, Reddcoin, Infintecoin и другие);
- Cuckatoo 31 и Cuckatoo 31 (MimbleWimbleCoin, Grin и более экзотические).
Таким ассортиментом не может похвастаться ни один другой производитель. Особенно если учесть наличие майнеров на Ethash. Обычно криптовалюта Ethereum и дочерние «монеты» «добываются» с использованием видеокарт и построенных на их основе ферм. Innosilicon создала майнеры для «эфира».
Тем не менее, в актуальную линейку майнеров Innosilicon 2022 года (по состоянию на весну 2022 года) входит четыре модели: две на Ethash и две на SHA-256. Рассмотрим их подробнее.
Ethereum-майнер, ориентированных на начинающих пользователей – при сохранении достаточно низкой цены он характеризуется оптимальной производительностью. Расчётная окупаемость – около 1 года в зависимости от курса криптовалюты и цены на электричество.
Технические характеристики майнера Innosilicon A10 Pro включают:
- Хэшрейт – 750 мегахэш в секунду;
- Энергопотребление – 1300 Ватт;
- Размеры и вес – 34,3×28,1×13,4 см, около 10 килограммов.
Хэшрейт может показаться достаточно низким для людей, привыкших работать с Bitcoin-майнерами. Однако стоит учесть, что это – ASIC для добычи Ethereum, он использует иной алгоритм. Поэтому стандартная методика подсчёта хэшрейта для него не слишком хорошо подходит.
Innosilicon A10 Pro был представлен ещё в мае 2020 года, однако сохраняет актуальность и по настоящее время.
Более современный Ethereum-майнер, который относится к восьмому поколению ASIC’ов компании. Был представлен в ноябре 2021 года, поэтому является, по сути, наиболее современной моделью (по состоянию на весну 2022 года). Расчётная окупаемость – около 9 месяцев в зависимости от тарифов на электропитание и курса криптовалюты.
- Хэшрейт – 1.5 терахэш в секунду;
- Энергопотребление – 2200 Ватт;
- Размеры и вес – 46,3×28×20,3 см, около 16,5 кг.
Innosilicon A11 – один из немногочисленных ASIC-майнеров компании, который оснащается встроенным блоком питания. Поэтому именно его чаще остальных выбирают криптовалютные энтузиасты. Для добычи криптовалюты достаточно подключить майнер к сети, настроить пул и кошелёк – и можно ждать ETH.
Существует и более производительная версия – Innosilicon A11 Pro. Она получила хэшрейт в 2 терахэш в секунду. Однако из-за дефицита полупроводников в настоящее время она снята с продажи, купить Innosilicon A11 Pro можно только у реселлеров или на вторичном рынке.
Топовый Bitcoin-майнер бренда. Был представлен в 2019 году, однако сохранил актуальность и по настоящее время, поскольку сохраняет высокую окупаемость. Она составляет в среднем 9–10 месяцев в зависимости от цены на криптовалюту и электричество.
Технические характеристики Innosilicon T3+ Pro 67T:
- Хэшрейт – 67 терахэш в секунду;
- Энергопотребление – 3300 Ватт;
- Размеры и вес – 33,8×29,3×20,7 см, около 13,5 кг.
Компания не раскрывает, какие именно чипы используются в этом ASIC-майнере. Тем не менее, реверс-инжениринг позволяет предположить, что устройство оснащается 12-нанометровыми микропроцессорами.
Флагман предыдущего поколения Bitcoin-майнеров бренда Innosilicon. В настоящее время эту модель обычно выбирают начинающие криптовалютные энтузиасты – она недорогая и позволяет «экспериментировать» с размещением устройства.
При ценах на криптовалюту, установившихся по состоянию на март 2022 года, окупаемость Innosilicon T2TH составляет около 8–9 месяцев (в зависимости от цены на электричество). Однако доходность тоже не слишком высока и составляет порядка нескольких долларов в сутки.
Технические характеристики Innosilicon T2TH:
- Хэшрейт – 29 терахэш в секунду;
- Энергопотребление – 2200 Ватт;
- Размеры и вес – 30,3×20,3×27,8 см, около 8 кг.
Майнер также поставляется со встроенным блоком питания, что упрощает его установку и настройку.
Большинство ASIC-майнеров Innosilicon оснащаются встроенными блоками питания. Однако некоторые модели поставляются без PSU. Кроме того, блоки питания – это всегда одни из самых уязвимых элементов конструкции майнерами, так как они значительно нагреваются при работе и чувствительны к запылённому воздуху или нестабильной влажности.
К счастью для криптовалютных энтузиастов, Innosilicon оснащает свои майнеры универсальными блоками питания. Поэтому в случае перегорания или другого повреждения подобрать новый PSU не составит труда.
Например, для работы с майнером Innosilicon A10 Pro подойдёт любой блок питания с мощностью не менее 1300 Вт и тринадцатью 6-пиновыми коннекторами.
Хэш-платы Innosilicon
Главный минус бренда Innosilicon – компания не выводит в открытую продажу комплектующие для «асиков». Включая принципиально важные. Поэтому купить хэш-плату Innosilicon практически невозможно – все представленные в иностранных интернет-магазинах комплектующие не новые, а снятые с «доноров» или восстановленные.
Тем не менее, хэш-платы Innosilicon поставляются в сервисные центры. Поэтому отремонтировать ASIC-майнер в случае пробоя или другого повреждения «внутренностей» всё-таки можно.
