1 | * QNAP Power Off |
2 | ||
3 | QNAP NAS devices have a microcontroller controlling the main power | |
4 | supply. This microcontroller is connected to UART1 of the Kirkwood and | |
372c1d6d | 5 | Orion5x SoCs. Sending the character 'A', at 19200 baud, tells the |
8cf46643 | 6 | microcontroller to turn the power off. |

8 | Synology NAS devices use a similar scheme, but a different baud rate, |
9 | 9600, and a different character, '1'. | |
