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-2136 and remove the power cord.1.
Unscrew the 4 rubber feet from the bottom of the LEC-2.
2136 System.
Open the cover upwards.3.
Note:
The motherboards can support up to 4 GB 1.
memory capacity in maximum.
Hard Disk Installation
The system can accommodate one Serial-ATA disk. Follow
these steps to install a hard disk into the LEC-2136:
Align the hard disk with the mounting holes on the 1.
chassis cover.
Secure the hard disk with 4 mounting screws on the 2.
cover from the outside.
Connect the Serial-ATA cable to the hard disk.3.
Plug the Serial-ATA cable to the Serial-ATA drive and 4.
power connectors on the main board.
Put the hard disk tray with the installed hard disk back 5.
to the system and secure it with the mounting screws.

System Memory Installation
The motherboard supports DDR3 memory. It comes with
one Double Data Rate type three (DDR3) Small Outline
Dual Inline Memory Modules (SO-DIMM) sockets.
Align the SO-DIMM connector key with the SO-DIMM 1.
socket key.
Install the SO-DIMM.2.

CompactFlash Card Installation
LEC-2136 provides one CompactFlash slot. To install the
CF card, follow these 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.
3G SIM Card Installation
Open the SIM tray and flip it diagonally.1.
Align the angled corner of the SIM card with the key 2.
of the SIM card socket. Make sure the ICs is in contact
with the reader.

Note:
To remove the Mini-PCIe module from the 1.
system, release the latch first by slightly bending
it inward.
To remove the SIM card, unlock the tray first by 2.
sliding it outward.
Insert the 3. SIM card into the tray diagonally. Close and
lock the tray.
3G Wireless Module Installation
Align the wireless module’s key with the Mini-PCIe slot 1.
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.

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.

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
system (or one pair of network ports in bypassed state;
However, only one function can be activated at a time.)
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 wd_bp folder under Driver
and Utility on the Driver and Manual CD
Set the access mode with these two parameters 2.
by editing the Makefile.linux directly: DIRECT_IO_
ACCESS= [0|1] (enter either 1 or 0) and LANNER_
DRIVER= [0|1] (enter either 1 or 0). 1 is for direct access
and no driver is needed. You will only need to execute
the program directly. However, when it equaled to 0,
driver installation is needed. Refer to the following
Install section for more details.
Type make to build source code:3.
make Makefile (Note: omit the file extensions)
After compiled, the executable program (bpwd_tst) and
the driver (bpwd_drv.ko) will be in the bin subdirectory.
Install on the Linux and FreeBSD
The installation procedures depend on the access mode
that you have set by using the above mentioned method.
If you have set DIRECT_IO_ACCESS=1, driver installation is
not necessary. Proceed to the next section on executing
If you have set DIRECT_IO_ACCESS=0, Lanner bypass
driver needs to be installed. Install the driver and create
a node in the /dev directory as shown in the following
example:
Executing the commands through the Command Line:
1. wd_tst --swtsr (Set Watchdog Timeout State to Reset)
2. wd_tst --swt xxx (Set Watchdog Timer 1-255 seconds)
3. wd_tst[*] --start (Start Watchdog Timer)
4. wd_tst --stop (Stop Watchdog Timer)
The following procedures are required for running the
watchdog program on DOS, Linux and FreeBSD.
Note:
For DOS environment, use DJGPP as compiler 1.
and the makefile: Makefile.dos.
For Linux, support kernel versions are 2.4.x and 2.
2.6.x. Use the makefile:Makefile.linux.

Build
To build program source code on Linux platform, use the
following steps as a guideline:
For Linux:
Insert module and create node in /dev as below
example:
#insmod wd_drv.[k]o
#mknod /dev/wd_drv c 241 0
For FreeBSD:
Insert module as below example:
#kldload -v ./wd_drv.ko
Execute
# wd_tst --swtsb (Set Watchdog Timeout State to Bypass
function)
# wd_tst --swtsr (Set Watchdog Timeout State to Reset
function)
# wd_tst --swt xxx (Set Watchdog Timer 1-255 seconds)
# wd_tst[*] --start (Start Watchdog Timer)
# wd_tst --stop (Stop Watchdog Timer)
Copy the proper makefile from the Driver and Manual 1.

Appendix A
DIRECT_IO_ACCESS=1, use the command: “./
wd_tst --swt xxx” to start the watchdog timer
instead .
Watchdog timer can support two functions, 2.
- system rest or LAN bypass. However, only
one function can be activated at a time. You
should modify the code or switch it to the
desired state/function accordingly.
For more details, refer to the README file 3.
