TIPI Features

Role of the Raspberry PI

The Raspberry PI is a linux system, that should be up and running before your TI is
powered on. Linux systems are not something you should just pull theh power on. There
is no power switch on a Raspberry PI. You shouuld consider leaving the Raspberry PI
always on. If you do need to turn it off, there is a shutdown feature in the web admin
interface provided by TIPI. After issuing a shutdown, wait for the PI's sd-card activity
light to stay off for 10 seconds, then pull the power.
