20G020-00 E5 – 2014-01-21
G20 - 3U CompactPCI® Serial Intel® Core™ i7 CPU Board
The G20 is a versatile 4HP/3U single-board computer supporting a multitude of
modern serial interfaces according to the CompactPCI® Serial standard. It is thus
perfectly suited for data-intensive applications which require high computing-
power. The CPU card is equipped with Intel®'s Core i7 processor running at up to
3.2 GHz maximum turbo frequency and offering multi-core architecture from
Intel® with full 64-bit support. The G20 supports the Intel® Active Management
technology which makes it possible to access the board via the network even when it
is in soft-off or standby state.
The memory configuration of the G20 includes a state-of-the-art fast DDR3 DRAM
which is soldered to the board to guarantee optimum shock and vibration resistance.
An mSATA disk connected via a SATA channel and a microSD™ card device which
is connected via a USB interface offer nearly unlimited space for user applications.
The board delivers an excellent graphics performance. Two DisplayPort® interfaces
are accessible at the board front. Using an external adapter two HDMI or two DVI
ports can also be realized. In addition the standard front I/O comprises two PCIe®-
driven Gigabit Ethernet and two USB 2.0 ports.
Serial interfaces at the rear I/O connectors are 8 USB, 6 SATA interfaces, one
DisplayPort® or HDMI (instead of one interface at the front panel), 5 PCI Express®
x1 links, and two PEG x8 links. Up to eight Gigabit Ethernet interfaces can be
realized using a rear I/O adapter board.
Thermal supervision of the processor and a watchdog for the operating system
complete the functionality of the G20.
The G20 operates in Windows® and Linux environments as well as under real-time
operating systems that support Intel®'s multi-core architecture. The InsydeH2O™
EFI BIOS was specially designed for embedded system applications.
The G20 is suited for a wide range of industrial applications, e.g. for monitoring,
vision and control systems as well as test and measurement. Main target markets
comprise industrial automation, multimedia, traffic and transportation, aerospace,
shipbuilding, medical engineering and robotics.
The G20 comes with a tailored passive heat sink within 4 HP height. The robust
design of the G20 makes the board especially suited for use in rugged environments
with regard to shock and vibration according to applicable DIN, EN or IEC industry
standards. The G20 is also ready for coating so that it can be used in humid and
dusty environments and has a guaranteed minimum standard availability of 7 years.

Product Safety
Lithium Battery
This board contains a lithium battery. There is a danger of explosion if the
battery is incorrectly replaced!
See Chapter 5 Maintenance on page 86.
Electrostatic Discharge (ESD)
Computer boards and components contain electrostatic sensitive devices.
Electrostatic discharge (ESD) can damage components. To protect the board and
other components against damage from static electricity, you should follow some
precautions whenever you work on your computer.
• Power down and unplug your computer system when working on the inside.
• Hold components by the edges and try not to touch the IC chips, leads, or cir-
cuitry.
• Use a grounded wrist strap before handling computer components.
• Place components on a grounded antistatic pad or on the bag that came with the
component whenever the components are separated from the system.
• Store the board only in its original ESD-protected packaging. Retain the original
packaging in case you need to return the board to MEN for repair.

RoHS
Since July 1, 2006 all MEN standard products comply with RoHS legislation.
Since January 2005 the SMD and manual soldering processes at MEN have already been completely lead-free.
Between June 2004 and June 30, 2006 MEN’s selected component suppliers have changed delivery to RoHS-
compliant parts. During this period any change and status was traceable through the MEN ERP system and the
boards gradually became RoHS-compliant.
WEEE Application
The WEEE directive does not apply to fixed industrial plants and tools. The compliance is the responsibility of the
company which puts the product on the market, as defined in the directive; components and sub-assemblies are
not subject to product compliance.
In other words: Since MEN does not deliver ready-made products to end users, the WEEE directive is not
applicable for MEN. Users are nevertheless recommended to properly recycle all electronic boards which have
passed their life cycle.
Nevertheless, MEN is registered as a manufacturer in Germany. The registration number can be provided on
request.
