Power Button
Press this button (Fig. 10, pos. 4) to switch the system on or off.
Please note the BIOS setup settings (BIOS Setup / Chipset / South Bridge Configuration / Restore on AC
Power Loss, setup options:
Power On
/ Power Off). “Power On” is the default setting.
Please also note the description in chapter 10.2 “Protection against Overheating”.
Prerequisite:
The CB 752 has to be connected to an appropriate main power supply (DC or AC via AC/DC adapter).
Even when the system is turned off via the power button there is still a standby-voltage of 5 VSb on the
SBC.
Switching the system off using the power button does not disconnect the device from the mains. The unit
is only completely disconnected from the mains, when the power cord is disconnected either from the
mains or the unit. Therefore, the power cord and its connectors must always remain easily accessible.
