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.

Product Overview
20G304-00 E1 2017-02-01 Page 8
1 Product Overview
1.1 Product Description
Unmanaged Industrial Ethernet Switch
The G304 is an unmanaged 3U Ethernet switch implemented as a CompactPCI Serial
board. It occupies one peripheral slot, using a 4 HP front panel with 4 Gigabit Ethernet
ports on RJ45 connectors, and one direct Ethernet connection to the CPU card using PCI
Express on P1. Options include M12 front connectors, and a P6 connector to extend the
number of Ethernet channels available on the board to six.
Reliable Communication System Component
The G304 supports full-duplex and half-duplex operation with auto-negotiation, high-
speed nonblocking store-and-forward switching. Its built-in test mechanisms make the
G304 an even more reliable component in the communication system.
In addition, the switch can act as Power over Ethernet Plus (PoE+) Power Sourcing
Equipment (PSE), supplying other devices on all ports with up to 30 W (class 0, 1, 2, 3, 4)
per port for power according to IEEE 802.3 Section 2 - Type 1 and 2 (formerly known as
IEEE 802.3at). The maximum power available for one G304 is limited to 61.6 W, according
to CPCI-S.0 specification.
Compliant to Railway Standards
The board is specifically designed for rugged mobile communication systems. It is
therefore, for example, fully compliant with the EN 50155 railway standard, screened for
a -40°C to +85°C operation temperature and ready for coating.
