3.5 Environmental Specification

Ambient temperature

» Operating: 0 to +60 °C
» Non-operating: -30 to +85 °C

Humidity

» Operating: 10% to 90% (non condensing)
» Non operating: 5% to 95% (non condensing)

3.6 MTBF

The following MTBF (Mean Time Between Failures) values were calculated using a combination of manufacturer‟s test
data, if the data was available, and a Bellcore calculation for the remaining parts. The Bellcore calculation used is

“Method 1 Case 1”. In that particular method the components are assumed to be operating at a 50 % stress level in a
40° C ambient environment and the system is assumed to have not been burned in. Manufacturer‟s data has been
used wherever possible. The manufacturer‟s data, when used, is specified at 50° C, so in that sense the following

results are slightly conservative. The MTBF values shown below are for a 40° C in an office or telecommunications
environment. Higher temperatures and other environmental stresses (extreme altitude, vibration, salt water
exposure, etc.) lower MTBF values.

5.1 Power supply

5.1.1 ATX connector

The miniBaseboard's power supply follows the ATX specification and in default configuration the baseboard should be
supplied by connecting an ATX PSU with 20pin ATX and 4pin ATX_12V supply cable in correct orientation. The 4pin
ATX_12V connector mainly supplies power to the module over 0R resistor R669. The module is supplied with 5V
standby voltage over 0R resistor R670.

The SD-Card standard is a standard for removable memory storages designed and licensed by the SD Card Association
(http://sdcard.org). The card form factor, electrical interface and protocol are all part of the SD Card specification.
COM Express™ Type 2 pin-out based modules may provide a SDIO interface shared with GPIO signals. Therefore on COM
Express™ miniBaseboard Type 2 a SD-Card connector is available. Please check the documentation of your module if
SDIO is supported.

Note: A SD-Card is detected if Card Detect is at low level. The write protection is active (read only) if SD_WP is at

high level.

5.8 Ethernet

The 10/100/1000 Base-T RJ45 single port Ethernet jack with integrated LEDs and magnetics on ETXexpress®
miniBaseboard is compatible to modules with Gigabit or with 10/100 Fast Ethernet Controller. By default the
configuration jumpers J20-J24 are closed for modules with Gigabit Ethernet. Open all Jumpers when using a module
with 10/100 Fast Ethernet controller.

The COM Express™ miniBaseboard Type 2 provides a RJ45/Dual USB Combo with a single RJ45 in combination with 2
USB ports (USB 4/6). Ethernet Connector J73 with integrated magnetics and LEDs is configured to support modules
with Gigabit Ethernet controller only. Modules with 10/100 MBit Ethernet controller are not supported.

interfaces like RS232 and parallel ports additionally to temperature, FAN and voltage monitoring features.

Modules with onboard Super-I/O may conflict with the standard LPC-I/O address 2Eh. Therefore it's possible on
ETXexpress® miniBaseboard to change the LPC address to 4Eh by closing jumper J25.

On COM Express™ miniBaseboard Type 2 the configuration jumpers J75 and J79 allow disabling the KBC or holding the
Super-I/O in reset to simulate a legacy free backplane.

VAROITUS: Paristo voi rãjãhtãã, jos se on virheellisesti asennettu. Vaihda paristo ainoastaanlaltevalmistajan

suosittelmaan tyyppiln. Havita kaytetty paristo valmistajan ohjeiden mukaisesti.

Spanish:

Precaución: 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.

Note: The battery of this product is not considered to be accessible by the end user. Therefore the safety

instructions are only given in English, German, French, Danish, Finish and Spanish language.

If the battery of this product however is accessible by the end user, it is in the responsibility of the

Kontron customer to give the corresponding safety instructions in the required language(s).

COM Express™ miniBaseboard Type 2 / Single Supply Mode

56

7 Single Supply Mode

The miniBaseboard is able to be supplied by just one voltage. This voltage has to be in the range of 8.5V to 18V
connected to the 4pin ATX_12V power connector J59.

To use this feature it is as well necessary to have a module supporting the wide range input as some small changes of
the assembly (see below). Are these constraints fulfilled, the onboard regulators begin to do the supply instead of the
ATX power supply. But some restrictions have to be cared about in this single supply mode.

» The onboard power regulators for 3.3V and 5V are limited to 6A each. After supplying the onboard devices,

there are 4.8A at 3.3V and 5.9A at 5V remaining. Therefore the total current of the used external devices (PCI,
PCIexpress, USB, LVDS panel, IDE/CF, RS232/LPT) must not exceed these limits in single supply mode.

» Additionally no PCI Card can be used, which needs -12V supply.
» If a wide range power supply is used, the PCI and PCIexpress slots are not supplied with 12V. A LVDS Display

has to be supplied separately or with 5V.

Limitations on ETXexpress® miniBaseboard in single supply operation:

» The FAN1 output voltage on J49 is similar to the input voltage in the range of 8.5V to 12V. For input voltages

from 12V to 18V the Fan output is limited to 12V. To fix FAN1 voltage output to 5V place R51 optionally.

» FAN2 (J50) is not supported except FAN2 voltage output is fixed to 5V by placing R52.

Limitations on COM Express® miniBaseboard Type 2 in single supply operation:

» Fan (J50) is not supported. Remove FB138 and place at FB137 to enable the Fan output (voltage similar to

the input voltage) or place at FB136 for 5V Fan output

Power save mode:

If optional power save mode is enabled (see assembly instructions) the system will shut down after a short time
(about 8 seconds) in S5 completely. This means that nearly no power is used from the power supply, because no
device will be supplied. But in this case it is only possible to wake up the system by pressing the power button for at
least one second.

Note: If power save mode is enabled the baseboard does not start automatically after connecting VCC. Press Power

Button SW2 to turn on your system.

7.1 Assembly Instructions ETXexpress® miniBaseboard

Follow the assembly instruction below to enable Single Supply operation:

For correct CPLD supply:

» Remove R710 (10kOhm; bottom)
» Mount R705 (100kOhm; bottom)
» Mount R61 (210kOhm; bottom)

To switch CPLD in single supply mode:

» Remove R712 (0R; bottom)
» Mount R711 (1kOhm, bottom)

To enable 5V Standby:

» Mount R46 (0R; top)
» Mount R60 (210kOhm; bottom)

To ensure that there is no short with the onboard generated voltages:

» Remove J58 (top), to ensure, that there is no short with the onboard generated voltages possible.

Optional:

» Remove R490 (0R, top) and mount on R491 (top) to enable the power save mode
» FAN1 output is 8.5V -12V. Place R51 (0R; bottom) to fix FAN1 output voltage to 5V
» FAN2 is not supported. Remove R53 (0R; bottom) and place it on R52 (bottom) to enable FAN2 with +5V

output voltage.

7.2 Assembly Instructions COM Express™ miniBaseboard Type 2

Follow the assembly instruction below to enable Single Supply operation:

To switch CPLD in single supply mode:

» Remove R712 (0R; bottom)
» Mount R711 (1kOhm, bottom)

To enable 5V Standby:

» Mount R46 (0R; bottom)
» Mount R60 (422kOhm; bottom)

To ensure that there is no short with the onboard generated voltages:

» Remove J58 (top), to ensure, that there is no short with the onboard generated voltages possible.

Optional:

» Remove R490 (0Ohm; top) and mount on R491 (top) to enable the power save mode
» Fan is not supported. Remove FB138 (Ferrit Chip Bead, 600 Ohm, 1A, 100MHz; bottom) and place it on

FB137(bottom) to enable Fan output voltage according to baseboard's input voltage or place it on FB136 to
fix Fan output voltage to +5V.

10 Security Advice

To protect the external power lines to peripheral devices the customer has to take care about:

- The wires to the external device have the right diameter to withstand the max. available current

- The housing of the external device fulfils the fire protection requirements of IEC/EN 60950.
