five. Inside the exam of repairing and changing the chip, the chip must be examined very first, and then the function check shall be performed immediately after passing. The purpose test must make sure that the little warmth sink is welded certified. When setting up the massive heat sink, the surface area with the chip must be evenly coated with thermal gel and the cooling lover shall be at entire velocity.
Repair approach: Test the appearance, evaluate the chip capacitor or resistance in entrance, generally It can be a result of bad chip soldering or maybe a chip capacitor, resistor harmful or abnormal resistance; VI. Control Board Difficulty Resulting in the Following Troubles one. The complete miner does not work one) Look at if the voltages at numerous voltage output points are usual. U8 can be disconnected to start with if three.3V is brief-circuited. If it remains to be small-circuited, the CPU might be unplugged for measurement. For other voltage abnormalities, commonly replace the corresponding converter IC. two) If your voltage is typical, make sure you Check out the welding status of the DDR/CPU. 3) Try to update the flash system with SD card; When the miner of which the Management board has actually been reflashed has to start out Typically, the following two steps are essential: a) Following the card Restoration is handed, the eco-friendly LED indicator will be generally on, and the power shall be restarted; b) Wait for 30s soon after powering on once more (the time class of turning on OTP).
The voltage of every voltage domain is about 0.32V. If there is 16V electrical power provide, commonly it has domain voltage. The priority is supplied to evaluate the output of the facility source terminal of the hashboard and Look at whether or not the MOS is short-circuited (measure the resistance between pins 1, four and eight). If 16V has electrical power source but no area voltage, proceed to examine.
log-domain voltage print command The specific operations are as follows: Open up putty , enter the IP of your miner in issue and click on OPEN Figure 6-7 2. Enter the person identify, password and check command to check the NONCE response standing along with the position of voltage area. If your NONCE and area voltage are irregular, person can carry out measurement and maintenance determined by the printed irregular chip.
Sign up for the worldwide community of miners who believe in minerstat to elevate their mining video game. Are you presently all set to unlock your mining likely?
three: After the conversion file is published, structure the SD card, decompress the test file, and duplicate it for the SD card. Then insert Buy Now the exam fixture card slot, electrical power on right until the fixture monitor displays, indicating that all your data files are mounted efficiently. Now it is possible to exam the hash board.
Maintenance technique: In the PT2 check, look at the serial port print log. It is frequently due to an error inside the sign-up tackle of a certain chip. Just exchange the BM5 chip as demonstrated in Figure five-19 (asic starts off from 0).
② Detect whether or not the circuits of U1 and U2 are irregular, like resistor in poor soldering, and many others.;
PS: In case the hashboard isn't powered or powered off according to the check sequence, creating R8, R9, U1, and U2 to burn up out, the chip will report 0;
a-four) Look at Should the pins of the very first chip are soldered effectively (it was observed all through repair which the pins are tinned observing within the side, however the pins will not be stained with tin in the least if the chip is eradicated)
9. The check fixtures at the maintenance close all utilize the Test_Mode manner and utilize the scan code method for testing.
If there isn't any issue with the connection, you can accomplish the PT2 take a look at on the single board to examine whether the take a look at can pass. If it could be handed, more than likely the Command board is faulty. If the take a look at fails, use the PT2 servicing approach to repair.
d-1) The first scenario: the check time is basically similar to the good board (typically the value of X will likely not improve each time you check) (test time refers to the time from when the beginning examination button is pressed to some time when the result of ASICNG: (X) is exhibited over the LCD).
a. Ensure the admirer connector has actually been plugged into the socket and there is no damage within the supporter cable. (Underneath pictures are poor socket and negative cable examples)
