Compliances and Certification
CE Certication
This product has passed the CE test for environmental
specifications. Test conditions for passing included
the equipment being operated within an industrial
enclosure. In order to protect the product from being
damaged by ESD (Electrostatic Discharge) and EMI
leakage, we strongly recommend the use of CE-
compliant industrial enclosure products.
FCC Class A Certication
This equipment has been tested and found to comply
with the limits for a Class A digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful
interference when the equipment is operated in a
commercial environment. This equipment generates,
uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction
manual, may cause harmful interference to radio
communications. Operation of this equipment in a
residential area is likely to cause harmful interference
in which case the user will be required to correct the
interference at his own expense.

EMC Notice
This equipment has been tested and found to comply
with the limits for a Class A digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when
the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in
accordance with the instruction manual, may cause
harmful interference to radio communications. Operation
of this equipment in a residential area is likely to cause
harmful interference in which case users will be required
to correct the interference at their own expense.
Safety Guidelines
Follow these guidelines to ensure general safety:
• Keep the chassis area clear and dust-free before,
during and after installation.
• Do not wear loose clothing or jewelry that could get
caught in the chassis. Fasten your tie or scarf and roll
up your sleeves.
• Wear safety glasses/goggles if you are working
under any conditions that might be hazardous to
your eyes.
• Do not perform any action that creates a potential
hazard to people or makes the equipment unsafe.
• Disconnect all power by turning off the power and
unplugging the power cord before installing or
removing a chassis or working near power supplies
• Do not work alone if potentially hazardous
conditions exist.
• Never assume that power is disconnected from a
circuit; always check the circuit.
LITHIUM BATTERY CAUTION:
Risk of explosion could occur if battery is replaced by an
incorrect type. Please dispose of used batteries according
to the recycling instructions of your country.
• Installation only by a trained electrician or only by an
electrically trained person who knows all the applied
or related installation and device specifications..
• Do not carry the handle of power supplies when
moving to other place.
• The machine can only be used in a fixed location
such as labs or computer facilities.
Operating Safety
• Electrical equipment generates heat. Ambient air
temperature may not be adequate to cool equipment to
acceptable operating temperatures without adequate
circulation. Be sure that the room in which you choose to
operate your system has adequate air circulation.
• Ensure that the chassis cover is secure. The chassis design
allows cooling air to circulate effectively. An open chassis
permits air leaks, which may interrupt and redirect the flow
of cooling air from internal components.
Electrostatic discharge (ESD) can damage equipment and
impair electrical circuitry. ESD damage occurs when electronic
components are improperly handled and can result in complete
or intermittent failures. Be sure to follow ESD-prevention
procedures when removing and replacing components to avoid
these problems.
• Wear an ESD-preventive wrist strap, ensuring that it makes
good skin contact. If no wrist strap is available, ground
yourself by touching the metal part of the chassis.
• Periodically check the resistance value of the antistatic
strap, which should be between 1 and 10 megohms
(Mohms).
Rack Mounting Installation Environment Precaution
1. Elevated Operating Ambient - If installed in a closed
or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than
room ambient. Therefore, consideration should be given
to installing the equipment in an environment compatible
with the maximum ambient temperature (Tma) specified
by the manufacturer.
2. Reduced Air Flow - Installation of the equipment in a rack
should be such that the amount of air flow required for
safe operation of the equipment is not compromised.
Mechanical Loading - Mounting of the equipment in the
rack should be such that a hazardous condition is not
created due to uneven mechanical loading.
3. Mechanical Loading - Mounting of the equipment in the
rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
4. Circuit Overloading - Consideration should be given to
the connection of the equipment to the supply circuit and
the effect that overloading of the circuits might have on
over-current protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be
used when addressing this concern.
5. Reliable Earthing - Reliable earthing of rack-mounted
equipment should be maintained. Particular attention
should be given to supply connections other than direct
connections to the branch circuit (e.g. use of power strips).”

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.
1. Unpower the LEC-7230 and remove the power cord.
2. Turn the device upside down.
3. Unscrew the 4 rubber feet from the bottom cover.
4. Open the cover.
Installing the System Memory
The motherboard supports DDR3L memory to meet the
higher bandwidth requirements of the latest operating
system and Internet applications. It comes with one Low-
Voltage Double Data Rate Three (DDR3L) Small Outline
Dual Inline Memory Module (SO-DIMM) socket.
1. Align the memory module’s key with the SO-DIMM
socket’s notch.
2. Install the SO-DIMM.
Note:
The system can support memory of DDR3L SO-
DIMM up to 4/8 GB depending on the CPU SKU.

Installing the Wireless Module
1. Align the wireless module’s key with the Mini-PCIe
slot notch.
2. Insert the wireless module into the connector
diagonally.
3. Fix the wireless module with the screws.
Installing the 3G SIM Card
1. Unlock the SIM card reader first by sliding it outward.
2. Flip the SIM card reader diagonally.
3. Put the SIM card into the reader. The angled corner of
the SIM ensures that the card fits only the correct way
in the reader. Make sure the ICs will be in contact with
the SIM card reader.
4. Close the tray. 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 outward to unlock it.
Installing the Disk Drive
The system can accommodate one Serial-ATA disk drive.
Follow these steps to install a hard disk into the system:
1. Align the mounting holes of the HDD/SSD and
that on the LEC-7230 systems as illustrated in the
following picture. Fix the hard disk on the system by
attaching the screws through the back cover from the
outside.
2. Plug the Serial-ATA cable to the disk.
3. Connect the Serial-ATA power and data disk cables to
the Serial-ATA power and disk connectors on the main
board respectively.

Installing CompactFlash Card
LEC-7230 provides one CompactFlash slot. Follow the
procedures below for installing a CompactFlash card.
1. Align CompactFlash card and the card slot with the
arrow pointing toward the connector.
2. Push the card to insert into the connector.
Notes about installing Windows 7 on CF Card
1. Press DEL to entry BIOS, the default setting of SATA
mode is “AHCI Mode”
2. Since we are installing Windows 7 operating system on
a CompactFlash card, which is ATA-based, please change
the “SATA Mode” from “AHCI Mode” to “IDE Mode”.
(BIOS -> Advanced -> IDE Conguration -> SATA Mode).
3. When the conguration is done, select “Save & Exit”
setup screen.
4. Press <Enter> on “Save Changes and Exit”. The pop-up
message will ask “Save conguration & exit” and choose
“Yes”. The system will reboot itself afterwards and the
setup is completed.
