To access some components and perform certain service
procedures, you must perform the following procedures
first.
WARNING: To reduce the risk of personal injury,
electric shock, or damage to the equipment,
remove the power cord to remove power from
the server. The power switch button does not
completely shut off system power. Portions of the
power supply and some internal circuitry remain
active until AC power is removed.
1. Unpower the LEC-2055 and remove the power cord.
2. Turn the device upside down.
3. Unscrew the 4 rubber feet from the bottom cover.

Wireless Module Installation
1. Align the wireless module’s cutout with the Mini-PCIe
slot notch.
2. Insert the wireless module into the connector
diagonally.
3. Push the other end of the wireless module to be
tightened with the latch.
3G SIM Card Installation
1. In order to insert the SIM card, you will have to take
off the front panel first. To take off the front panel,
unscrew the 4 screws on the front panel.
2. Align the cut corner of the SIM card pointing toward
SIM card reader. Also place the ICs facing down.
3. Insert the SIM card into the tray horizontally. You
should feel a click when the SIM card is locked securely
in the SIM card reader.
Note: To remove the SIM card, push the card
inward toward the connector to unlock it.

Hardware Setup
Installing the Hard Disk
Connecting Power
The system can accommodate one Serial-ATA disk. Follow
these steps to install a hard disk into the system:
Connect the LEC-2055 to a 12~36 VDC power source.
The DC power-in connector comes with a 2-pin terminal
block for its Phoenix contact. This power socket can only
accept the power supply with the right pin contact so be
cautious when inserting power to the system.
1. Place hard disk on the hard disk tray of the top cover
and align the holes of the hard disk with the mounting
holes on the tray.
2. Fix the hard disk on the hard disk tray by using 4
mounting screws
DC IN
+ -
3. Plug the Serial-ATA cable to the hard disk.
4. Connect the Serial-ATA power and data disk cables to
the Serial-ATA power and disk connectors on the main
board respectively.

Wall Mounting
The product does not ship with wall mounting kit. You
could purchase the wall mounting kit from Lanner as an
accessory. To mount your product on the wall, follow the
instructions below:
1. First make a hole for the anchor in the surface on the
wall. Use the following diagram as a guideline for
placing the anchors.
2. Then press the anchor into the hole until it is flush with
the surface. You may need a hammer to tap the wall
anchor.
3. Use a screwdriver to screw the threaded screw into the
plastic anchor.
4. Attach the wall mounting bracket to the back of the
device, securing it in place with four of the flat-head
screws provided.
5. Hang the device on the wall.

Programming Watchdog
Timer
A watchdog timer is a piece of hardware that can be
used to automatically detect system anomalies and reset
the processor in case there are any problems. Generally
speaking, a watchdog timer is based on a counter that
counts down from an initial value to zero. The software
selects the counter’s initial value and periodically restarts
it. Should the counter reach zero before the software
restarts it, the software is presumed to be malfunctioning
and the processor’s reset signal is asserted. Thus, the
processor will be restarted as if a human operator had
cycled the power.
For sample watchdog code, see watchdog folder under
LEC-2055 Utility on the Driver and Manual CD

file:
#include <stdio.h>
#include <string.h>
#include <dos.h>
#include <stdlib.h>

Executing through the DOS Command Line:
{
Execute the 83627WD.exe xxx (xxx=1-255 sec) under
DOS (83627WD.exe and CWSDPMI.EXE should be placed
in the same directory), then enter the values from 0~255.
The system will reboot automatically according to the
time-out you set. For sample code, look into the DOS/WD
folder.
clrscr();
Compile and Executing in Linux:
if( argc < 1 || argc != 2 )
To run the Watchdog sample code, you will need
to compile first by running make with the Makefile
contained in the source code. After compilation, you will
have the following binary files:
int i, time;
{
help();
printf(“\t\t argc = %d\n”, argc);
1. wdrs_drv.ko (Kernel mode driver module)
2. wdrs_test (the executable Watchdog program)
Note: You have to run “mknod /dev/wdrs_drv c 244 0” to
create the device file as driver installation. For source code,
look into the linux/watchdog_reset folder. Make sure you
copy all files within the folder to the destination.
The following shows the sample code 83627uhg_wdto
