Observer Matrix : Matrix CLI : Matrix CLI : system power on
   
system power on
The system power on command powers on the system and allows traffic to flow.
The web server and SSH/CLI server are always on, albeit in a low-level state if the appliance is OFF but has power to it. The only way to ensure all systems are off is to completely remove all power. By having the web server and SSH/CLI server in a low-power state allows you to remotely turn on the system when you do not have immediate physical access to the appliance. Another reason might be that the settings in system power power-loss are configured to have the system power off if power is lost and then restored. In this instance, the system would be OFF, but because it has power you can remotely turn the system on. This command has the same effect as pressing the Power button on the front of the system.
