With the Antminer S19, This implies the control board will only boot with firmware which has a valid digital signature from Bitmain.
Following the fix and substitution chip checks, it is crucial to execute a complete chip Examine ahead of continuing on the functional check. The practical check need to make sure the double-sided warmth sinks are soldered the right way and the cooling enthusiast is functioning at full speed.
Be aware: this text is made up of Recurrent comparisons amongst the T21 towards the S21. They had been released simultaneously, so it only is sensible.
Step one from the repair service method will involve a visible inspection of the hash board to get fixed. The technician should look for any obvious signs of injury, for instance deformation or burns to the PCB.
Disconnect the Aged Control Board Carefully disconnect the 3x eighteen-pin sign cables, PSU electricity extension cable, voltage regulating cable, and 4x supporter cables within the old control board.
Just like the S21 stock firmware, the T21 inventory firmware and GUI permits improved mistake dealing with, which subsequently can make miner management much more successful.
3. After the decompression is completed, a folder Using the same name since the compressed package deal will surface, along with the decompressed folder are going to be ready for use.
There are 20 10R0 chip resistors on The full board, distributed among the voltage domains about the back of the hashboard. The principle operate would be to conduct the voltage area of The entire board in a very restricted method to realize the voltage balance amongst the voltage domains.
The PIC chip dsPIC33EP16 is situated within the higher still left facet from the reverse side from the hashboard, and there's a batchminer overall of one PIC chip on The complete board.
2. Insert the card reader to the OTG cable, and insert the OTG cable (or directly insert the OTG U disk) in to the Micro USB port to the front from the miner.
Keep away from Static Discharge: When managing the control board, use anti-static wrist straps and Focus on anti-static mats to avoid static electric power from damaging the board.
Once the defective chip has long been Positioned, the technician must re-solder the chip. The technician need to add flux throughout the chip, ideally no-thoroughly clean flux, and warmth the solder joints on the chip pins to a dissolved standing.
Aluminum heatsinks are mounted with spring screws which evens tension on all chips, bringing about much better heat dissipation.
Original Check Operate: Once configured, Permit your miner operate for a short period to make sure it is actually operating accurately. Monitor the miner's standing through the interface to look for any problems or warnings.
