b) If 1 chip are available in move a), it implies that the very first chip as well as the past circuit are ordinary. Use an identical strategy to examine the next chips. One example is, if the 1V2 exam place and RO examination level involving the 38th and 39th chips are small-circuited, if the log can locate the 38th chip, then there's no challenge with the initial 38 chips. If 0 chips remain observed, first Examine whether or not the 1V2 is normal.
This spare section is specifically designed for easy maintenance and repair in the S19 Professional hash board, ensuring seamless functions and higher-functionality mining.
seven. When powering over the hashboard, user have to to start with link the unfavorable copper wire of the ability provide, then the constructive copper wire of the ability source, and finally plug within the signal cable. When taking away, the buy of installation has to be reversed. First take away the signal cable, then clear away the favourable copper wire of the power source, And eventually clear away the destructive copper wire of the facility source.
a) Liquid crystal display display ASICNG: if (0), 1st measure the whole voltage of your measuring area and the Raise circuit 20V is ordinary, and then utilize the small circuit probe to shorter-circuit the RO exam place plus the 1V8 examination stage between the main and the 2nd chip, after which you can function the program to locate the chip. Examine the serial port log, if 0 chip is still observed at this time, it will be amongst the following scenarios: a-one) Make use of a multimeter to measure if the voltages in the 1V8 and 0V8 take a look at points are one.8V or 0.8V. Otherwise, it implies the one.8V or 0.8V LDO circuit of this area is irregular, or The 2 ASIC chips of this area is not really soldered very well; most problems of the phenomenon are due to shorter circuits of 0.8V, 1.8V patch filter capacitors (measure the resistance of your patch filter capacitors relevant to the front and back of the PCBA). a-two) Check whether or not the circuits of U2, U3 and U4 are irregular, including resistance welding, and many others. a-3) Evaluate the resistance of R232 or R233 which has a multimeter to check whether it is inside of one ohms along with the looking at will likely not soar randomly. Otherwise, remember to substitute these two resistors. a-4) Look at In the event the pins of the initial chip are soldered perfectly (it was found throughout repair which the pins are tinned observing through the aspect, however the pins are certainly not stained with tin in the least if the chip is eliminated). b) If just one chip can be found in action a), it implies that the 1st chip and also the former circuit are excellent. Use an analogous strategy to examine the next chips. Such as, quick-circuit the 1V8 examination point plus the RO exam point amongst the 38th and 39th chips. If your log can find 38 chips, the primary 38 chips haven't any issue; if you continue to locate 0 chips, check the 1V8 first; if It truly is normal, it means that there's a trouble Using the chips immediately after 38. Carry on to analyze with dichotomy till the problematic chip is located. Assuming that there is a difficulty With all the Nth chip, if the 1V8 and RO amongst the N-1th and Nth chips are brief-circuited, N-1 chips are available, but when the 1V8 and RO between the Nth and N+1th chips are short circuited, your entire chip can not be uncovered.
Utilize the hashboard tester of the V2.2010 Command board. The beneficial and detrimental poles with the tester should be put in with discharge resistors. It is recommended to employ a cement resistor of 25 ohms and greater than 100W.
In the event that numerous chips in a similar domain have a reduced reaction level, the 1 With all the reduced nonce in that area must be replaced.
Kernel Log: it keeps records of ANTMINER's Procedure levels, which serves as a means to troubleshoot some typical issues. The method to enter the miner log: enter the miner IP tackle in the deal with bar of Google or Firefox browser >> enter the consumer name/password (default root/root) >> the miner log
Repair system: Utilizing the dichotomy approach, small-circuit the 1V8 test stage plus the RO exam stage involving the 38th and 39th chips With all the limited circuit probe. In the event the log can find 38 chips, there is not any issue with the very first 38 chips; if quick-circuiting the 47th chip, although the log experiences 46th, it signifies that the 47th chip can not be detected, and there is no challenge with the Visible inspection. Typically, the 47th chip shall be replaced;
Microsoft and DuckDuckGo have partnered to offer a look for Resolution that delivers applicable ads for you although preserving your privacy. When you click on a Microsoft-presented advert, you will be redirected to the advertiser’s landing site through Microsoft Promoting’s System.
If one chip is identified, Go Here check the subsequent chips making use of an identical system and quick-circuiting the 1V8 examination position plus the RO test level among the 38th and 39th chips to Find the problematic chip.
In the event the miner is in the fault point out, you ought to Test the current log. Should the miner is in a normal state, it is suggested to question the historic log.
Repair method: Utilizing the dichotomy approach, limited-circuit the 1V8 examination level and also the RO exam place involving the 38th and 39th chips from the quick-circuit probe. If the log can discover 38 chips, there's no problem with the very first 38 chips; if short-circuiting 47 chips, though the log studies forty six, it implies the 47th chip can not be detected, and there is no issue Using the Visible inspection. Commonly, the 47th chip shall get replaced;
Should the serial port stops long-length operating after the limited-circuit, it means the initial chip is OK. In line with this process, discover the chip that also fails after a long-distance operating after a chip brief circuit. Typically, it's attributable to a destroyed chip, and you may substitute it;
The voltage of every voltage area is about 0.36V. When there is 14V ability supply, typically it's got area voltage. The precedence is specified to evaluate the output of the facility supply terminal from the hashboard and whether the MOS is brief-circuited (evaluate the resistance involving pins one, 4 and 8). If 14V has electrical power provide but no domain voltage, keep on to check.
