1Introduction
This manual describes the KTA75/Flex family of boards made by KONTRON
Technology A/S. These board will also be denoted KTA75 within this
Users Guide.
The KTA75 is designed to support the listed APU variants (uPGA 722pin
processors) and AMD A75 Fusion Controller Hub (FCH) A75 on a Flex form
factor. See the chapter System Specifications for more specific
details.

The 4 versions have the same type of active CPU cooler (the cooler is
by default not premounted, but can be ordered with this obtion).
Use of this Users Guide implies a basic knowledge of PC-AT hard- and
software. This manual is focused on describing the KTA75 board’s
special features and is not intended to be a standard PC-AT textbook.
New users are recommended to study the Installation Procedure stated
in the following chapter before switching-on the power.
All configuration and setup of the CPU board is either done
automatically or manually by the user via the BIOS setup menus. Only
exceptions are the Clear CMOS jumper and the Always On jumper.

Warning: Turn off PSU (Power Supply Unit) befor configuring
the board and do not hot plug power supply, otherwise
components (RAM, LAN cards etc.) might get damaged.
!
!
Warning: 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. Do not use
washers with teeth as they can damage the PCB and may cause
2Installation Procedure
2.1 Installing the Board
To get the board running, follow these steps. If the board shipped
from KONTRON has already components like RAM mounted, then relevant
steps below can be skipped.
1. Turn off the PSU (Power Supply Unit)
2. Insert the DDR3 UDIMM 240 Pin module(s)
Be careful to push it in the slot(s) before locking the tabs.
3. Connecting Interfaces and PSU
Insert all external cables for hard disk, keyboard etc. A
display/monitor must be connected in order to be able to change
BIOS settings. Connect a standard ATX/BTX PSU to the board by the
inserting power cables into 24-pin ATX and the 4-pin ATX+12V PWR
plugs connectors.
4. Power Button
Turn on mains power to the PSU. If board doesn’t boot, then
PWRBTN_IN must be toggled; this is done by shorting pins 16
(PWRBTN_IN) and pin 18 (GND) on the FRONTPNL connector (see
Connector description), by use of a “normally open” switch etc.
5. 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.
6. Mounting the board to chassis
It is recommended using screws with integrated washer and having
diameter of approx. 7mm.
Note: To clear all BIOS settings, including Password protection,
activate Clear CMOS Jumper for ~10 sec (without power connected).

2.2 Requirements IEC60950
Users of KTA75 should take care when designing chassis interface
connectors in order to fulfil the IEC60950 standard.
Lithium battery precautions
CAUTION!
Danger of explosion if battery is
incorrectly re- placed. Replace only
with same or equivalent type
recommended by manufacturer. Dispose
of used batteries according to the
manufacturer’s instruc- tions.
VORSICHT!
Explosionsgefahr bei unsachgemäßem
Austausch der Batterie. Ersatz nur
durch den selben oder einen vom
Hersteller empfohlenen gleichwertigen
Typ. Entsorgung gebrauchter Batterien
nach Anga- ben des Herstellers.
ATTENTION!
Risque d'explosion avec l'échange
inadéquat de la batterie. Remplacement
seulement par le même ou un type
équivalent recommandé par le
producteur. L'évacuation des batteries
usagées conformément à des indications
du fabricant.
PRECAUCION!
Peligro de explosión si la batería se
sustituye incorrectamente. Sustituya
solamente por el mismo o tipo
equivalente recomendado por el
fabricante. Disponga las baterías
usadas según las instrucciones del
fabricante.
ADVARSEL!
Lithiumbatteri –Eksplosionsfare ved
fejlagtig håndtering. Udskiftning må
kun ske med batteri af samme fabrikat
og type. Levér det brugte batteri
tilbage til leverandøren.
ADVARSEL!
Eksplosjonsfare ved feilaktig skifte av
batteri. Benytt samme batteritype eller
en tilsvarende type anbefalt av
apparatfabrikanten. Brukte batterier
kasseres i henhold til fabrikantens
instruksjoner.
VARNING!
Explosionsfara vid felaktigt
batteribyte. Använd samma batterityp
eller en ekvivalent typ som
rekommenderas av apparattillverkaren.
Kassera använt batteri enligt
fabrikantens instruktion.
VAROITUS!
Paristo voi räjähtää, jos se on
virheellisesti asennettu. Vaihda
paristo ainoastaan lalteval- mistajan
suosittelemaan tyyppiln. Hävitä
käytetty paristo valmistajan ohjeiden
mukaisesti.
When an interface or connector has a VCC (or other power) pin which is
directly connected to a power plane like the VCC plane:
To protect the external power lines of the peripheral devices the
customer has to take care about:
•That the wires have suitable rating to withstand the maximum
available power.
•That the enclosure of the peripheral device fulfils the fire
protecting requirements of IEC60950.
