How to use Whatsminer Test Fixtures? (Take M20 series as an example)
Ⅰ. Burning the test file:
1. Prepare a 4G or 8G SD card, and then go to the Whatsminer official website to download the corresponding SD card swipe program.
2. After the download is complete, unzip PhoenixCardV4.1.2.zip.
3. Run the PhoenixCard app
4. Insert the SD card into the computer with a card reader, the PhoenixCard application will automatically recognize the SD card, then click "Firmware", select the image in the compressed package, select the mass production card for the type of card, and finally click "Burn card".
5. When the progress bar turns green, it means that the SD card burning is completed.
6. Take out the SD card and insert the test fixture control board, and use the 12V DC power supply to power on the tester control board. After power up, the control board automatically reassembles the system. During the process of burning the card, the red light flashes, and after a few minutes the green light turns on, and the burning of the card is completed.
Ⅱ. Adjust the voltage and current, and connect the test cables
1. Adjust the current of the adjustable power supply to 10A and the voltage to 13V. (To test different types of miners, you need to select the corresponding output voltage of the hash board)
2. Connect the 12V power cable to the test fixture and insert the network cable. Then connect the positive and negative poles of the adjustable power supply to the hash board, and finally connect the hash board and the test fixture with a data cable.
3. Power up the test fixture first, then power up the hash board. It should be noted that when the power is turned on, different hash boards need to be replaced for testing. The power-on and power-off sequences are as follows:
(1) Power on: connect the power cord first, and then connect the data cable
(2) Power off: first unplug the data cable, then unplug the power cord
Ⅲ. Whatsminer Test fixture setup
1. IP settings
After we get the Whatsminer test fixture, we need to use a network cable to connect it to the computer. The test fixture does not need to be connected to the Internet, but is directly connected to the computer to prevent IP conflicts.
Then open the computer's "Network Settings", select "Local Area Connection", and select "Internet Protocol Version 4 (ICP/IPv4)".
Because WhatsMiner's test jig has a fixed IP address, we need to manually enter the IP address: 192.168.2.245. As shown below:
After the setting is complete, click "OK".
2. Testing software settings
After completing the IP settings, we need to install and run the WhatsMiner fixture management software "MobaXterm".
First select the "Session" button to enter:
Then select "SSH":
Enter IP: 192.168.2.22 in the "Remote host" text box. Check the "Specify username", enter "root" in the "Specify username" text box; then click "OK".
Ⅳ. Enter the test interface
Add the IP address, click "OK", the software will automatically enter the test interface:
1. Enter root after "password:" (IP is subject to input, this is for reference only) Enter root (it is not displayed)
2. Enter root to confirm, then click Yes.
3. Enter the test interface
Test instructions and precautions:
In the Whatsminer test fixture, it is necessary to input the corresponding command to complete the test.
RST signal is set to low level 0V: echo 0 > /sys/class/gpio/gpio99/value, can repair the failure of reset failure
RST signal is set to high level 1.8V: echo 1 > /sys/class/gpio/gpio99/value, can repair the failure of reset failure
Restart the control panel: reboot
General test: test-readchipid (number of chips test)
Performance test: test-hashboard (chip and computing power test)
Note: When testing with the regular test command test-readchipid, the single board can be tested individually. When the performance test command test-hashboard is tested, the hash board must be installed with upper and lower radiators, and a fan should be used to dissipate the heat of the hash board.
