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 power switch button does not
completely shut off system power. Portions of the
power supply and some internal circuitry remain
active until power is removed.
Unpower the LEC-7920 and remove the power cord.1.
Turn the device upside down.2.
Unscrew the 4 rubber feet from the bottom cover.3.
Open the cover.4.

Note:
The system can support memory of DDR3 SODIMM up to 8 GB in maximum.
Installing the System Memory
The motherboard supports DDR3 memory to meet the
higher bandwidth requirements of the latest operating
system and Internet applications. It comes with two
Double Data Rate Three (DDR3) Small Outline Dual Inline
Memory Module (SO-DIMM) socket.
Align the memory module’s cutout with the SO-DIMM 1.
socket’s notch.
Install the SO-DIMM.2.
Installing the CPU
The system supports Intel CPU i5, i7 and Celeron P4500
processor which should be installed on the motherboard’s
micro-PGA 989 socket.
To install the CPU to the socket, follow these steps:
Align the CPU’s triangle with the socket’s triangle.1.
Embedded and Industrial Computing

Chapter 4
Hardware Setup
Place the CPU inside the socket and turn the knob all 2.
the way until it is horizontally opposite to its original
position to lock the CPU securely.
Wireless Module Installation
Align the wireless module’s cutout with the Mini-PCIe 1.
slot notch.
Insert the wireless module into the connector 2.
diagonally.
Push the other end of the wireless module to be 3.
tightened with the latch.
3G SIM Card Installation
Unlink the SIM card reader first by sliding it outward.1.
Flip the SIM card reader diagonally.2.
Align the cut corner of the SIM card with the cut corner 3.
of the SIM card reader. Make sure the ICs will be in
contact with the SIM card reader.
Insert the 4. SIM card into the reader and close the tray.
You should feel a click when the SIM card is locked
securely in the SIM card reader.
Note:
If the CPU thermal pad mounting breaks apart,
use your hands to reattach the falling parts and
stick them together.
Lock
Note: To remove the SIM card, push the card
outward to unlock it.

Hardware Setup
Installing the Hard Disk
The system can accommodate one Serial-ATA disk. Follow
these steps to install a hard disk into the system:
Take out the hard disk tray and fix the hard disk on 1.
the tray with 4 mounting screws as illustrated in the
following picture.
Plug the Serial-ATA cable to the hard disk.2.
Place the hard disk back to the system’s chassis and fix 3.
it with the mounting screws.
Connect the Serial-ATA power and data disk cables to 4.
the Serial-ATA power and disk connectors on the main
board respectively.

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. Use the following diagram as a guideline for
placing the anchors.
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.

Appendix A
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

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.
