1. There are two parallel trapezoidal sockets on each Bitmain Antminer S19 series power plug. It is advised to use two power cords with a combined current of at least 10A.
2. When turning on the machine, plug in the two power cords first and then turn on both power cords simultaneously through the socket switch; to turn off the machine, turn off the power through the switch, unplug the cord, and then replug it in.
3. If the two power cords cannot be turned on and off at the same time, when powering on the machine, first plug in AC1 on the outside and then AC2 on the inside; when powering off the machine, cut off the AC2 on the inside first, and then off AC1 on the outside.
