IP can't be detected, the quantity of lovers is irregular, and also the chain is abnormal. If there is an abnormality during the check, follow the monitoring interface and exam LOG prompts for servicing.
a) Once the flashing is effective, the eco-friendly LED indicator light-weight is usually on, and afterwards the facility is turned off and restarted;
② Visually inspect whether or not you will discover noticeable signs of burnt sections, areas effect offset or missing elements, etc.
Measure whether the domain voltage is usual. Typically, the area voltage will likely be abnormal during the problematic area. Then measure the RI signal to check out In case the RI signal is broken. In case the RI signal is lacking, fundamentally, the chip is short-circuited or damaged following remaining tinned.
a) Liquid crystal display display ASICNG: if (0), first measure the full voltage with the measuring area as well as the boost circuit 20V is ordinary, and after that utilize the limited circuit probe to limited-circuit the RO take a look at issue as well as the 1V8 check level in between the first and the second chip, after which run This system to find the chip.
Disclaimer: Remember to Be aware this information demonstrates only minerstat supported features and might vary in the functions that the actual mining components delivers. Success from mining calculator are estimation dependant on The present issues, block reward, and exchange amount for particular coin.
Our replacement hashboards are not merely refurbished, They're upgraded to make sure much better functionality and dependability than the first. Just about every hashboard goes by way of a rigorous recovery procedure that makes them extra reliable than new types straight from your producer.
If the EEPROM NG is shown to the LCD screen of your hash board tester, check if the welding of U5 is regular.
In the event the ambient temperature is simply too substantial, it is a snap to set off the large-temperature protection mechanism of the miner. If the thing is the following info inside the log, it means that the running temperature in the miner is simply too substantial.
Other engines like google affiliate your advertisement-click habits which has a profile on you, which may be utilized later on to target adverts for you on that internet search engine or around the Internet.
All through testing, it is assumed the domain voltages of all domains in front of the irregular place are Just about all less than 0.3V, whilst the area voltages of the subsequent domains are Just about all better than 0.
3. After repairing, the hash board needs to be tested in excess of two occasions to get Okay prior to it could possibly go! four. Verify whether the applications and hash board testers can operate Ordinarily, determine the upkeep station to check software package parameters, exam fixture variations, and so on. 5. Within the check of repairing and replacing the chip, the chip should be examined initially, after which the purpose check shall be done following passing. The function check need to make sure the small warmth sink is welded qualified. When setting up the big heat sink, the surface area in the chip have to be evenly coated with thermal gel plus the cooling admirer shall be at full velocity. When using the chassis to dissipate warmth, 2 hash boards needs to be placed concurrently to sort an air duct. 6. When measuring the sign, use four enthusiasts as aid for heat dissipation, as well as the followers shall manage comprehensive pace. seven. When powering within the hash board, the person will have to very first join the detrimental copper wire Get It Here of the power provide, then the favourable copper wire of the power provide, And at last plug in the signal cable. When removing, the purchase of set up needs to be reversed. Very first, take away the sign cable, then take out the constructive copper wire of the facility source, And eventually eliminate the adverse copper wire of the facility offer. Should the person does not adhere to this purchase, it's very very easy to trigger damage to R8, R9, U1, U2 (not all chips can be found). In advance of screening the pattern, the repaired hash board has to be cooled down in advance of screening, or else, it may well induce PNG tests. 8. To replace a different chip, printing pins and soldering paste are needed to make certain the chip is pre-soldered and afterwards soldered to your PCBA for repair. III. hash board tester generating and issues needing notice The supporting fixture of your hash board tester should really satisfy the warmth dissipation from the hash board and facilitate the measurement of indicators. one. Make use of the 19 collection hash board tester SD card swiping program for The very first time to update the hash board tester Handle board FPGA, unzip it and replica it on the SD card, after which insert the cardboard into the hash board tester card slot; electricity on for around one minute and wait for the Command board indicator to double flash 3 periods, then the update is finished; (if It isn't up to date, it could trigger a particular chip to generally be undesirable over the check). Figure 3-1 2. Make the test SD card Based on the requirements, and right unzip the compressed deal of The one-sided warmth sink inspection chip to create the SD card; Determine three-2 3. The examination SD card will be built In line with the requirements, plus the double-sided heat sink 8-periods patter exam needs to make an SD card, as demonstrated while in the figure below;
4. For that take a look at of chip upkeep and replacement, it is necessary to detect the chip first, after which you can do a purposeful examination following passing. The useful check ought to make certain that the modest heat sink is soldered nicely and the massive warmth sink is set up in place (Just about every thermal conductive adhesive have to be used evenly ahead of setting up the massive warmth sink).
Make reference to the voltage value range explained with the sign craze. In case the measurement encounters a considerable deviation on the voltage value, it might be in contrast Along with the measured price of the adjacent group to determine.
