Warning: Turn off PSU (Power Supply Unit) completely (no mains power connected to the
PSU) or leave the Power Connectors unconnected while configuring the board. Otherwise
components (RAM, LAN cards etc.) might get damaged.
Do not use PSU’s without 3.3V monitoring watchdog, which is standard feature in ATX PSU’s.
Running the board without 3.3V connected will damage the board after a few minutes.

Warning: When mounting the board to chassis etc. please notice that the board contains
components on both sides of the PCB which can easily be damaged if board is handled
without reasonable care. A damaged component can result in malfunction or no function at all.
1 Installation procedure
1.1 Installing the board
To get the board running, follow these steps. In some cases the board shipped from KONTRON has already
components like DRAM, CPU and cooler mounted. In this case relevant steps below, can be skipped.
1. Turn off the PSU (Power Supply Unit)
2. Insert the DDR3 DIMM 240pin DRAM module(s)
Be careful to push it in the slot(s) before locking the tabs. For a list of approved DDR3 DIMM modules
contact your Distributor or FAE. DDR3-800/1066 DIMM 240pin (PC3-6400/PC3-8500) are supported.
3. Install the processor
The CPU is keyed and will only mount in the CPU socket in one way. Use the handle to open/ close the
CPU socket. Penryn and Meron CPU’s via mPGA479 or mPGA478 ZIF Socket are supported, refer to
supported processor overview for details.
4. Cooler Installation
Use heat paste or adhesive pads between CPU and cooler and connect the Fan electrically to the
FAN_CPU connector.
5. Connecting Interfaces
Insert all external cables for hard disk, keyboard etc. A CRT monitor must be connected in order to
change CMOS settings.
6. Connect and turn on PSU
Connect PSU to the board by the ATX/BTXPWR and the 4-pin ATX+12V connectors. Alternatively use only
the 4-pin ATX+12V connector if single voltage operation (+12V +/-5%) is requested. Notice that single
voltage operation has limited power support for add-on cards etc. Turn on power.
7. Power Button
The PWRBTN_IN must be toggled to start the Power supply; this is done by shorting pins 16
(PWRBTN_IN) and pin 18 (GND) on the FRONTPNL connector (see Connector description). A “normally
open” switch can be connected via the FRONTPNL connector.
8. BIOS Setup
Enter the BIOS setup by pressing the <Del> key during boot up.
Enter Exit Menu and Load Optimal Defaults.
Refer to the “BIOS Configuration / Setup“ section of this manual for details on BIOS setup.
9. Mounting the board to chassis
When fixing the Motherboard on a chassis it is recommended using screws with integrated washer and
having diameter of ~7mm.
Note: Do not use washers with teeth, as they can damage the PCB and may cause short circuits.
Installation procedure
Note: To clear all CMOS settings, including Password protection, move the Clear CMOS jumper in the
Clear CMOS position (with or without power) for ~10 sec. This will Load Failsafe Defaults and make sure
Secure CMOS is disabled.
