led控制
绿联NAS的LED灯通过主板上的I2C总线控制，需通过Linux系统调用i2c-tools和特定驱动模块（如i2c-i801.ko）实现底层操作。通过开源ugreen_leds_cli工具可方便操作led。
下载开源工具ugreen_leds_cli：https://github.com/miskcoo/ugreen_leds_controller/releases ugreen_leds_cli帮助文档：
Usage: ugreen_leds_cli [LED-NAME...] [-on] [-off] [-(blink|breath) T_ON T_OFF]
[-color R G B] [-brightness BRIGHTNESS] [-status]
LED_NAME: separated by white space, possible values are
{ power, netdev, disk[1-8], all }.
-on / -off: turn on / off corresponding LEDs.
-blink / -breath: set LED to the blink / breath mode. This
mode keeps the LED on for T_ON millseconds and then
keeps it off for T_OFF millseconds.
T_ON and T_OFF should belong to [0, 65535].
-color: set the color of corresponding LEDs.
R, G and B should belong to [0, 255].
-brightness: set the brightness of corresponding LEDs.
BRIGHTNESS should belong to [0, 255].
-status: display the status of corresponding LEDs.
示例：
# 关闭电源灯
sudo ./ugreen_leds_cli power -off
# disk1的led闪黄灯
sudo ./ugreen_leds_cli disk1 -color 255 255 0 -blink 400 600
