Reset Button
Press the
Reset
button on the front panel continuously for at least 5 seconds to load the
factory default
configuration
. After the factory default configuration has been loaded, the system will reboot
automatically. The
Ready
LED will blink on and off for the first 5 seconds, and then maintain a steady glow
once the system has rebooted.
We recommend that you only use this function if the software is not working properly, and you want to load
factory default settings. To reset an embedded Linux system, always use the software reboot command
/>reboot
to protect the integrity of data being transmitted or processed. The Reset button is not designed
to hard reboot the DA-660A Series.
ATTENTION
Pressing the Reset button will only load the configuration file. All files in the
/etc
directory will revert to
their factory defaults, and
all user data in the Flash ROM will be deleted.
