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 PDUs in the LAN), and there is a script named "power" installed which controls a [http://www.powerswitchtail.com PowerSwitch Tail[EHL]] via GPIOcabinet #1. To control Be sure to shut down the supply of AC individual nodes before removing power , and remember to the Viridis chassis:# Log into the Raspberry Pi remove power from Iraq: <code>ssh raspi</code># Issue each of the appropriate "redundant power" command:#* Get supplies (via 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 onleft and right PDUs): <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.}}
