introduction

In April, the S17 Pro mining machine equipped with Bitmain's second-generation 7nm chip was launched. The S17 Pro supports the SHA256 algorithm, supports mining of encrypted digital currencies such as BTC and BCH, and supports three working states: low power mode, standard mode and cool frequency mode.

The power board is integrated with the mining machine, and the dual fans are arranged side by side for air intake. The air inlet is as follows:

Because dual power supply requires a one-to-two power cord (power cord specification is 3*1.5 square or more)

Air outlet: Dual fan exhaust

Mining machine evaluation

(Note: Since the mining machine has dual power supplies, a two-way power cord is required to ensure normal operation of the machine )

Mining pool and mining machine settings:

A: Find the mining machine IP: After power is supplied, the mining machine starts to start. After the green light of the mining machine starts to flash, find the mining machine IP, open the software, click "Start", press the IP button on the mining machine, and the mining machine IP will be fed back on the computer.

B: After finding the IP of the mining machine, enter the obtained IP address on the web page, enter the username and password, enter the mining machine background, set the IP, and then click "Save&Apply" to save.
