38. Keep on to use the binary strategy to examine right until the problematic chip is observed. Assuming that there is a challenge Along with the Nth chip, once the 1V2 and RX among the N-1th chip and also the Nth chip are quick-circuited, the N-one chip are available; Nonetheless, in the event the 1V2 and RX between the N and N+1 chips are limited-circuited, the full chip can't be found.
d-one) The primary circumstance: the examination time is essentially the same as The great board (commonly the value of X is not going to adjust every time you check) (take a look at time refers back to the time from when the beginning test button is pressed to the result of ASICNG: (X) shown around the Liquid crystal display). This situation is likely being because of the abnormal resistance welding on the entrance and rear CLK, CI, and BO from the Xth chip, so users shall target these 6 resistors. The tiny probability is because of X-one, X, X+1, that's, Amongst the 3 chips, the following pins irregular welding ailments of the chip manifest: Determine 5-16 d-2) The 2nd circumstance: the take a look at time is almost 2 times as long as The great board (in some cases the value of X will modify each time you take a look at, and sometimes X=0); right now, the log normally has the subsequent details (the red selection is just not thirteen, dependant upon which seat the hash board tester is connected to); through the exam, assume the area voltage of all of the fields in front of the irregular position is sort of fewer than 0.
If your miner whose Handle board is flashed ought to get started Usually, the following two techniques are demanded:
six. The repaired hash board should be tested by using a examination fixture, and it Order Now must move more than two periods to be judged as a superb products. For the first time, immediately after replacing the add-ons, look forward to the hash board to cool down, use the examination fixture to check, and when is passed, put it on 1 facet right before cooling down. The second time, look forward to the hash board to chill down wholly just before screening.
As for The difficulty that the control board simply cannot start off (not networked), the consumer needs to switch the U1 (major Manage IC FBGA of Regulate board). U1 can no longer be Utilized in 19 collection right after replacement
In the event the miner nevertheless loses hashrate, lessen the frequency and other situations keep on being unchanged. Let the miner mine to find out if it's going to reduce hashrate and if the hash board will hit X. If it even now hits X in dropping hashrate, then clear away the warmth sink in the hashboard for mining and await the hashrate to fall.
Kernel Log: it keeps information of ANTMINER's operation levels, which serves as a method to troubleshoot some popular concerns. The tactic to enter the miner log: enter the miner IP tackle within the address bar of Google or Firefox browser >> enter the consumer title/password (default root/root) >> the miner log
Most likely, the IP can not be identified as a result of irregular operation. Seek advice from the main place for troubleshooting.
Maintenance personnel have to have Digital understanding, no less than one year of servicing working experience, and proficiency in BGA/QFN/LGA packaging and welding engineering.
In line with this process, discover the chip that also has the long-phrase working failure immediately after a specific chip is brief-circuited. Normally, it is actually brought on by a certain chip detrimental, so just replace it;
During testing, it truly is assumed the area voltages of all domains in front of the abnormal area are Just about all fewer than 0.3V, while the domain voltages of the following domains are Virtually all increased than 0.
(1) When ASICNG=(0) is shown: to start with measure the whole voltage of your area and also the 19V boost circuit is standard, after which you can use a brief-circuit probe to brief the RX examination stage and 1V2 examination place between the No.
Check whether the conductive copper bar is in lousy contact, Examine whether or not the electrical power Command wire is unfastened or damaged, and change the power provide.
