Power on

Power on is designed to use an external power-on switch. The external switch turns on one board; this board then turns on slave boards.

The physical on-off switch is shorted in on-position.

Power off

Raspberry Pi initiates turn off, which orders Teensy (boards) to turn off after the Raspberry shutdown. A request power off button will tell the Raspberry that it is time to shut down.
