5. IMMERSION COOLING
5.1 PREPARING THE MINER FOR THE DIVE
- Flash the miner with the BiXBiT firmware that matches your device.
- Flash the power supply of the miner with BiXBiT firmware for the corresponding model or prepare a suitable fan simulator (“trick”).
- Turn off and remove the main fans of the miner ①, ②
- Open the power supply cover and remove the fan ③
If it is impossible to flash the power supply at the previous stages, install the fan simulator in the appropriate slot ④.
- Clean the elements of the case and the board of the miner from dust and dirt.
- Immerse the miner in the immersion liquid.
5.2a UPDATING THE POWER SUPPLY UNIT FIRMWARE FOR M2X SERIES MINERS
The power supply of the miner is flashed solely for the purpose of immersion diving and disabling the check of the power supply fan.
Currently there is no option to roll back the power supply firmware for air cooling operation.
OPTION 1: AUTOMATIC PSU FIRMWARE UPDATE VIA MINER WEB INTERFACE
- Open miner web interface
- Go to the section Configuration > Miner Configuration
- Select tab PSU Firmware
- To automatically update the firmware of the power supply, press the button [Upgrade PSU Firmware] ①
In case of errors when updating the firmware of the power supply, instead of the standard fan of the unit, you must install a suitable fan simulator (“trick”).
OPTION 2: UPDATE THE PSU FIRMWARE USING THE UTILITY WHATSPOWERTOOL
- Follow the link https://bixbit.io/en/firmwares#Whatsminer_PSU
- In the section corresponding to the power supply unit of your miner, click Download
The file will start downloading with the extension Bin.
The process of flashing the PSU miner is completely similar to the process of flashing the miner itself, described in section 4.1, except that instead of the Bin-file of the miner firmware, you must use the Bin-file downloaded in the previous step for the power supply.
5.2b DISABLING POWER SUPPLY FAN CHECK FOR M3X, M5X SERIES MINERS
The disabling of the fan check of the miner's power supply is for immersion purposes only.
- Open miner web interface
- Go to the section Configuration > Miner Configuration
