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

. /etc/motd

d. /etc/password k. /etc/protocols

e. /etc/ramfs.img l. /etc/rc

f. /etc/resolv.conf m. /etc/services

. /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.
