ZEUS MINING has organized and updated the latest manual of the Innosilicon A11 series miner maintenance guide, which can help the maintenance personnel to quickly troubleshoot and repair the fault of the A11 series miner hash board.
1. From left to right, the hash board is Hashboard 1---Hashboard 4;
2. There is no SPI cable, the A11 series control board and the hash board are connected through the adapter board.
There are currently 6 types of models:
A11 Samsung particle, there are 8G and 16G;
A11M Magnesium Particles, 16G;
A11MX Magnesium Particles, 8G;
A8P is equivalent to A11
A8PM is equivalent to A11M
A8PMX is equivalent to A11MX
Due to the different DDR particles (brand, particle capacity), each model cannot be assembled at will!
It is not recommended to mix hash boards / hash modules until you understand the machine properties. The premise of assembling the hash boards / hash modules is that the SN code information pasted on the barrel of the whole miner is consistent.
There are two types of SN code information:
RA51: such as RA51A21A2400441
RB51: such as RB51XN21C090704
The mutual assemble principle of the RB51 SN code:
1. They can be directly assemble with each other;
The mutual assemble principle of the RA51 SN code:
1. The sixth digit of SN code must be the same;
2. Both are AG or both are BG;
3. For A11M miners, those produced in 21 and 22 cannot be mixed (Look the 7th and 8th of SN code).
1. Before powering on, you need to use the buzzer gear of the UT890D+ multimeter to detect whether there is a short circuit fault at the power supply end of the hash board;
2. If there is a short circuit in the hash board, you need to disconnect the hash board and the power supply, measure the hash board separately, and find the short-circuited hash board;
3. First observe whether the appearance of the short-circuit hash board is defective, and then remove each hash board module one by one until the short-circuit hash board module is found;
4. If there is no short circuit, you can power on the whole miner, plug in the internet cable, scan the miner operation status and error information (refer to the picture below for the error code), and locate the faulty hash board;
5. Shut down the miner, take out the faulty hash board, visually inspect and locate the faulty hash board module, or test the faulty hash board by using the repair platform / using the barrel + test control board (refer to the figure below) (the method is similar to the repair of T3 + hash board), according to the error message from the repair platform, remove the faulty hash module and prepare for maintenance.

Ⅰ. Introduction of A11 series miner models
A11 series miner models, in terms of assembly, have two obvious differences with other models, please refer to the following figure:1. From left to right, the hash board is Hashboard 1---Hashboard 4;
2. There is no SPI cable, the A11 series control board and the hash board are connected through the adapter board.
There are currently 6 types of models:
A11 Samsung particle, there are 8G and 16G;
A11M Magnesium Particles, 16G;
A11MX Magnesium Particles, 8G;
A8P is equivalent to A11
A8PM is equivalent to A11M
A8PMX is equivalent to A11MX
Due to the different DDR particles (brand, particle capacity), each model cannot be assembled at will!

3. For A11M miners, those produced in 21 and 22 cannot be mixed (Look the 7th and 8th of SN code).
Ⅱ. Construction of repair platform
The repair platform used to repair the A11 hash board needs to use the A11 control board whose repair program has been burned into the control board (the repair program is divided into Samsung RA51 and magnesium RB51, and each repair post is equipped with 2 repair-specific control boards) , and the power board for single-module testing, or the power board of the A11 itself, use the power supply of the A11 itself or a 12V constant voltage power supply. The repair platform is built as follows:
Ⅲ. Troubleshooting of faulty miners
Taking the maintenance of the faulty miner as an example, the repair steps are as follows:1. Before powering on, you need to use the buzzer gear of the UT890D+ multimeter to detect whether there is a short circuit fault at the power supply end of the hash board;
2. If there is a short circuit in the hash board, you need to disconnect the hash board and the power supply, measure the hash board separately, and find the short-circuited hash board;
3. First observe whether the appearance of the short-circuit hash board is defective, and then remove each hash board module one by one until the short-circuit hash board module is found;
