Quick Start
Steps to Power-down the CRB
There are three options for powering-down the CRB:
1. Use OS-controlled shutdown through the menu (or equivalent).
2. Press the power-button on the motherboard at SW1 to begin power-down.
3. If the system is hung, it is possible to asynchronously shut the system down by
pressing the power-button continuously for 4 seconds.
Caution: Intel does not recommend powering down the board by removing power to the DC
power supply or disconnecting the DC input from the board.
