Adapting Circuit for LEDs, Beep Sound, Power Button

Recommended Posts

I try to develop an adapting circuit for LEDs, Beep Sound, Power Button and Fan fail sensing.

It ables to receive and send commands to COM1.

In case of over temperature or fan failure, it will send a shutdown command to shutdown the NAS.

If any HDD crash, it will receive a command and send out a long beep sound.

Any body had tried these functions with different method? (I mean using scripts or programs)

version 0.8

 

- Press power button 2S for normal shutdown

- Press power button over 10S for emergency shutdown (as power off MB)

- CPU fan below 922rpm or SYS fan below 692rpm, send fan fail command and shutdown command

 

recommend to disable Soft Power off option on BIOS (holding 4 seconds).
