Correct way to shutdown/reboot ClusterBox

Hello

I wonder what is the correct method to shutdown and restart the ClusterBox if it is required?
I am currently using:

sudo halt
sudo reboot

via ClusterBox console.

Sometimes after sudo halt the fan stays running and the power button does not respond to the reboot request. I kindly ask if this method is correct?
I also ask if sudo reboot provides for sending the shutdown to the Blade3 accordingly?

Thanks

clusterbox is positioned as a small server that starts immediately after receiving power, so it supports the reboot command (if mixtile users need to use sudo), and can be powered off if it needs to be shut down
