Product Safety
Product Safety
Electrostatic Discharge (ESD)
Computer boards and components contain electrostatic sensitive devices.
Electrostatic discharge (ESD) can damage components. To protect the PCB
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 circuitry.
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.
Only store the product in its original ESD-protected packaging. Retain
the original packaging in case you need to return the product to MEN for
repair.

Conformity
MEN products are no ready-made products for end users. They are tested according to
the standards given in the Technical Data and thus enable you to achieve certification of
the product according to the standards applicable in your field of application.
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
Nevertheless, MEN is registered as a manufacturer in Germany. The registration number
can be provided on request.
Copyright © 2017 MEN Holding. All rights reserved.
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.

1 Product Overview
1.1 Product Description
High Performance for Virtualization Applications
The G25A is a high-performance multicore CPU platform based on Intel's Xeon D-1500
System-on-a-Chip (SoC). Paired with I/O cards, the G25A can be ideally used for
transferring data from and to storage media, the Internet via LTE, wireless, copper or
optical Ethernet. Its up to 16 processor cores and built in Intel® VT-d and VT-x support
make the board ideally suited for virtualization applications.
The G25A offers high data bandwidth on both the front and the rear I/O interfaces. Two
10 Gigabit Ethernet interfaces are available on RJ45 or M12 connectors at the front, for
example.
USB 3.0, SATA revision 3.x, PCI Express 3.0 and Gigabit Ethernet interfaces on front and
rear complement the I/O possibilities of the board.
Ruggedized Memory and Mass Storage
The memory configuration of the G25A includes a state-of-the-art fast DDR4 DRAM with
ECC which is soldered to the board to guarantee optimum shock and vibration
resistance. A microSD card device offers space for user applications or as a local boot
medium.
System Security and Board Management
For system security, a Trusted Platform Module is assembled on the board. A board
management controller provides thermal supervision of the processor and a watchdog
for the operating system.
Perfect for Embedded and Harsh Environments
The G25A operates in Windows and Linux environments as well as under real-time
operating systems that support Intel's multi-core architecture.
The G25A comes with a tailored heat sink within 4 HP height. All components are
soldered for protection against shock and vibration according to applicable DIN, EN or
IEC industry standards. The G25A 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.
G229 I/O Extension Board
The G229 offers one m.2 slot, three USB 3.0 interfaces, one RS232 interface, one RS422/
485 interface, one VGA via PCI Express Mini card and up to three flexible slots for two
additional RS232 or RS422/485 interfaces. It is combined with the G25A to form a space-
saving solution with a bigger heat sink.
