EM-1220 LX User’s Manual
Introduction
Additional Functions
Reset Button
Press the
Reset
button on the EM-1220-DK 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. 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 EM-1220-DK.
ATTENTION
Resetting to factory defaults will not format the user directory and will not erase all of the user’s
data. Loading factory defaults will only load the configuration file. The files in the EM-1220-LX
that will be replaced include:
a. /etc/boa.conf
h. /etc/group
b. /etc/hosts
i. /etc/inetd.conf
c. /etc/inittab
j. /etc/motd
d. /etc/password
k. /etc/protocols
e. /etc/ramfs.img
l. /etc/rc
f. /etc/resolv.conf
m. /etc/services
g
. /etc/version
n. /home/httpd/index.html
ATTENTION
This function only takes effect when the user directory is working correctly. If the user directory
has crashed, the kernel will automatically load the factory defaults.
Real-time Clock
The EM-1220-LX’s real time clock is powered by a lithium battery. We strongly recommend that
you do not replace the lithium battery without the help of Moxa’s support team. If the battery
needs to be changed, contact the Moxa RMA service team for RMA service.
ATTENTION
The battery may explode if replaced by an incorrect type. To avoid this potential danger, always
be sure to use the correct type of battery.
