Introduction

Introduction

Thank you for choosing the LEC-2280. The LEC-2280 is
an upgrade platform of Lanner LEC-2280 and features
Intel Ivy Bridge i3, i5, and i7 processors. It has dual LAN
as well as HDMI and DVI-D connectors for high demand
of Internet and video playback applications. The LEC-2280
also features slim and compact chassis design to allow
heat to dissipate off directly from the top of the platform.

The LEC-2280 also offers a variety of different expansion
opportunities to further customize the platform. Two
different expansions are possible.

On model LEC-2280E, it comes with one PCIe.

On model LEC-2280P2, it comes with 2 PCI slots.

These expansions adds capabilities of video capture or
extended LAN connections.

The following highlight the functionalities of the LEC­2280 system:

Intel HD Graphics Engine •

Dual video output of VGA and HDMI or VGA and DVI-D •
with Intel integrated HD graphic engine

Dual 10/100/1000 Mbps LAN •

USB x 6 (2 by internal pin header) and COM x 2 •

1 SATA 6Gbps HDD bay support and 1 SATA-DOM •
connector

Totally 2 serial ports supporting Hardware Auto flow •
Control: DB9 x2 for RS232/422/485

Audio input and output through Mic-in and Line-out •
jack

Dual Mini-PCIe Socket (with on SIM card reader for 3G •
wireless Internet connection) can extend the capability
for Wi-Fi or Bluetooth

Aluminum extrusion enclosure which helps heat •
dissipation

Customization opportunity for expansion of extra LAN •

To erase the CMOS data:

Turn off the computer and unplug the power cord.

Move the jumper cap from pins 1-2(default) to pins 1.
2-3. Keep the cap on pins 2-3 for about 5-10 seconds,
then move the cap back to pins 1-2.

Plug the power cord and turn on the computer.2.

Enter BIOS setup to re-enter data.3.

Serial-ATA Connector (SATA1/SATA2): It is for connecting
a 2.5’’ hard disk to be served as your system’s storage. It
can support SATA 3.0 which features Data transfer rates
up to 6.0 Gb/s (600 MB/s). SATA 2 connector also supports
SATA-DOM (the power line of SATA-DOM can be disabled
with a jumper on, see SATA_PW2).

The controller contains two modes of operation—a
legacy mode using I/O space, and an AHCI mode using
memory space. Software that uses legacy mode will not
have AHCI capabilities.

The AHCI ( Advanced Host Controller Interface) is a
programming interface which defines transactions
between the SATA controller and software and enables
advanced performance and usability with SATA. Platforms
supporting AHCI may take advantage of performance
features such as no master/slave designation for SATA
devices—each device is treated as a master—and
hardware assisted native command queuing. AHCI also
provides usability enhancements such as Hot-Plug.

Use the BIOS menu to configure your hard disk
to be AHCI compatible.

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-2280 and remove the power cord.1.

Unscrew the 4 threaded screws from the top cover.2.

Open the cover.3.

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.

Note:

If the CPU thermal pad mounting breaks apart,

use your hands to reattach the falling parts and

stick them together.

Note:

The system can support memory of DDR3 SO­DIMM up to 16 GB in maximum with 2 SO-DIMM
sockets.

PCI/PCIe Riser Card Installation

The system can accommodate one PCIe expansion (or two
PCI expansion on model P2) module. In order the install
the PCIe expansion module, a low-profile riser card has
to be installed first. Follow these steps to install the riser
card:

Fix the riser card on the bracket with 3 screws.1.

Install the riser card to the system by connecting the 2.
connectors with the system’s PCIEIO1 connector.

Fix the riser card on the board.3.

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.

Programming System
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-2280 Utility in the Driver and Manual CD

Programming Watchdog Timer

Executing through the Command Line:

Execute the WD.EXE file under DOS (WD.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.
