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.

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

1 Product Overview

1.1 Product Description

Maintenance Free and Extremely Rugged

The NM30 family is a range of 8-port fanless and maintenance-free managed Ethernet

switches, developed specifically for rough environmental conditions in rolling stock and

automotive applications.

High Speed, High Efficiency and Extensive Protocols

The NM30 range of managed switches provide the additional ability to configure,

manage and monitor the LAN which allows more control over how data travels through

the network and who has access. The use of the identical firmware as provided for the

G101 Ethernet Switch, simplifies complex administration and reduces efforts for

administrator training.

Versatile Application Possibilities

The NM30 range provide eight channels at the front panel, accessible through M12

connectors and cover different application requirements, and either 100 Mb or 1Gb

Ethernet interfaces.

Compliant to Railway and Automotive Standards

The voltage supply for the NM30 Managed Ethernet Switch is designed for maximum

flexibility and supports wide range input supply voltages from 14.4 to 154 VDC, and

meets all EN50155 class S2 requirements for voltages ranging 24 to 110 VDC.

Conduction Cooled

The NM30 is designed for fanless operation at temperatures ranging from -40 to +70°C.

The NM30 features IP40 protection when surface-mounted and cooling fins which serve

as a heatsink for the internal electronics, and in this way provides conduction cooling.

Familiar Family Concept

As a member of MEN's family of extremely rugged industrial box PCs, the NM30

provides the same flexibility and scalability, as well as a look and feel which is common

to the family.
