Chapter 4: Hardware Setup
Preparing the Hardware Installation
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 front panel Power On/Standby button
does not completely shut off system power.
Portions of the power supply and some internal
circuitry remain active until AC power is removed.
Unpower the LEC-2250 and remove the power cord.1.
Unscrew the 4 rubber feet from the bottom cover of 2.
the LEC-2250 System.
Open the cover.3.
Note:
The motherboards can support up to 4 GB 1.
memory capacity in maximum.
The CF has to be installed first (if it is needed) 2.
before you install the RAM due to space
contention.
You will need to take off the heat sink first to 3.
access the SO-DIMM slot.
Uninstalling the heat sink by unscrewing
the screws from the side of the chassis
Installing the SO-DIMM
Installing the System Memory
The motherboard supports DDR3 memory to meet the
higher bandwidth requirement of the latest operating
system and Internet applications. It comes with one
double data rate type three (DDR3) Small Outline Dual
Inline Memory Modules (SO-DIMM) socket.

Hardware Setup
Installing the Hard Disk
The system can accommodate one Serial-ATA disks. Follow
these steps to install a hard disk into the LEC-2250:
Unscrew the 4 rubber feet from the bottom cover of 1.
the LEC-2250 System.
Place hard disk on the top cover of the system and 2.
align the holes of the hard disk with the mounting
holes of the top cover.
Secure the hard disk with 4 mounting screws from the 3.
outside of cover.
Connect the Serial-ATA power and data cables to the 4.
hard disk’s connectors.
Plug the Serial-ATA cables (power and data) to the 5.
Serial-ATA Connectors on the main board.

Installing the CompactFlash Card
LEC-2250 provides one CompactFlash slot. Follow the
procedures bellow for installing a CompactFlash card.
Align CompactFlash card and the card slot with the 1.
arrow pointing toward the connector.
Push the card to insert into the connector.2.
Note:
The motherboards can support up to 4 GB 1.
memory capacity in maximum.
The CF has to be installed first (if it is needed) 2.
before you install the RAM due to space
contention.
Installing the 3G SIM Card
Unlock the SIM card reader by sliding it outward and 1.
flip it up diagonally.
Align the cut-corner of the SIM card with the SIM card 2.
reader. Make sure that the ICs will be in contact with
the bottom of the reader.
Insert the 3. SIM card into the reader diagonally. Close
and lock the reader. You should feel a click when the
2
SIM card is locked securely in the reader.
Installing the Wireless 3G Module
Align the wireless module’s cutout with the Mini-PCIe 1.
slot notch.
Insert the wireless module into the connector 2.
diagonally.
Fasten the wireless module to the board with the 3.
screws (Use the Mini-PCIe module screws contained
within the package).
Installing the Wi-Fi Module
Follow the same steps as the Wireless 3G Module
Installation.

Wall Mounting
The product ships with wall mounting kit. To mount your
product on the wall, follow the instructions below:
First make a hole for the anchor in the surface on the 1.
wall.
Then press the anchor into the hole until it is flush with 2.
the surface. You may need a hammer to tap the wall
anchor.
Use a screwdriver to screw the threaded screw into the 3.
plastic anchor.
Attach the wall mounting bracket to the back of the 4.
device, securing it in place with four of the flat-head
screws provided.
Hang the device on the wall.5.

Programming Watchdog Timer
Appendix A: 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 Watch dog and DIO folder
in the Driver and Manual CD
Click the Setup program.1.
The welcome screen appears. Click Next to proceed.2.
Driver Installation
Before you could access or control the operation of the
watchdog and Digital I/O functions, install the the L_IO
driver which is the library and driver needed for Lanner
General Purpose Input/Output interface or functions.
To install the L_IO driver:
Restart the computer, and then log on with 1.
Administrator privilege.
Insert the Drivers and User’s Manual CD to the USB-2.
optical drive.
Browse the contents of the support CD to locate the 3.
file LannerIO v101.rar under the \WD_DIO\ folder and
unzip the file.
Click the Setup program in the unzipped folder.4.
The installation process proceeds. Click Close when the 3.
process completes.

To verify the GPIO driver installation, do the following
steps:
Right-click on the My Computer icon, and then select 1.
Properties form the menu.
Click the Hardware tab, then click the Device Manager 2.
button.
Select 3. View from the menu and select show hidden

San for hardware changes button from the tool bar.
Sample Program
Via the Demo Program
Enter the number of seconds to start count down before
the system can be reset. Press start to start the counter
and stop to stop the counter.
Via the Command Line
Execute the executable file in the program folder, then
enter the values from 1~255. The system will reboot
automatically according to the time-out you set.
