AC to the Viridis chassis is controlled by a Raspberry Pi on the LAN controlled by Iraq. The Pi can be used to test connectivity (i.e., check to see what is reachable from PDU in the LAN), and there is a script named "power" installed which controls a [http://www.powerswitchtail.com PowerSwitch Tail[EHL]] via GPIO. To control the supply of AC power to the Viridis chassis:# Log into the Raspberry Pi from Iraq: <code>ssh raspi</code># Issue the appropriate "power" command:#* Get the AC power status: <code>power status</code>#* Turn the AC power on: <code>power on</code>#* Turn the AC power off: <code>power off</code>#* Power-cycle the AC (turn off, pause, turn on): <code>power reset</code> {{Admon/caution|Possible Filesystem Damage!|As with any system, it's important to shut down each node before powering the chassis off.}}
