This method applies to all Antminers.
To power off/shut down a miner:
Since the miner is directly connected to the power supply, there is no hard switch on the miner. You only need to pull the power plug (pulling the plug, not the power cable) to disconnect the power.
To restart/reboot a miner:
There are two ways to restart the miner. The first is to power off the miner and then turn it on. The second is to click "restart" on the interface of the miner, as shown in the figure below:
Miner Background> System> Restart
