Product Safety

Read the user manual carefully before using the product. Keep the user manual for later

reference.

Conditions for Use, Field of Application

The product is designed to function correctly in the market, application area and

environmental conditions specified in the applicable standards which are listed in the

Technical Data.

Use cases in environments exceeding the specifications in the applicable standards and

the Technical Data have to be agreed upon between MEN and the customer.

Electrostatic Discharge (ESD)

Qualified Personnel

The product/system described in this documentation may be operated only by

personnel qualified for the specific task in accordance with the relevant documentation,

in particular its warning notices and safety instructions. Qualified personnel are those

who, based on their training and experience, are capable of identifying risks and

avoiding potential hazards when working with these products/systems.

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, 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.

20NL33-00 E1 2019-02-13 Page 7

Product Compliance

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.

If the product delivered was certified by MEN and is modified by the customer, e.g., by

installing an additional hardware component, the certification achieved by MEN

becomes invalid and has to be repeated for the new product configuration.

RoHS

MEN is committed to develop and produce environmentally compatible products

according to the Restriction of Hazardous Substances (RoHS) Directive 2011/65/EU

(formerly 2002/95/EC) of the European Union.

Since July 1, 2006 all MEN standard products comply with RoHS legislation.

REACH

MEN is a manufacturer of electronic products and thus a so-called "downstream user" in

terms of REACH. The products MEN supplies are solely non-chemical goods. Moreover

and under normal and reasonably foreseeable circumstances of application, the goods

supplied shall not release any substance.

Beyond that, according to REACH – Art.33, MEN will inform the customer immediately

should a substance contained in an MEN product (with a content of > 0.1%) be classified

alarming by the European Chemicals Agency (ECHA).

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.

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

20NL33-00 E1 2019-02-13 Page 10

1 Product Overview

1.1 Product Description

"NL" Family Principle

MEN's "NL" Ethernet switch family principle is based on a wide range of configuration

options (e.g., amount of Ethernet ports, fiber connections or Power over Ethernet) to

easily adapt the switch to application requirements.

Flexible Concept in a Small Housing

The NL33 is a 24+2-port fully managed layer 2/3 Ethernet switch, providing a wide range

of configuration options with 24 M12 Gigabit Ethernet ports. M12 connectors can be

configured to be A-, D- or X-coded and combinations are also possible. The X-coded

connectors are designed as push-pull and screwed variants (Harting concept). The NL33

offers two optional Ethernet fiber ports with 1000BASE-SX as standard variant. The

mechanical concept is an extremely compact, high-quality aluminum housing providing

high port density and ultra-high ruggedness. It is designed for wall-mounting, but

mounting in a 19" rack is also an option.

Performance, Security and Diagnostic Features

The 29 Gbit/s, TCAM based, store-and-forward switching matrix of the NL33 allows high-

performance layer 2 switching over all connected interfaces. For easy remote

management and access, layer 3 protocols, e.g., IPv4/IPv6 and DHCP, are integrated. The

switch provides extended security features like SNMPv3, SSH and HTTPS. Traffic isolation

(VLAN) and switching redundancy protocols (e.g., STP, RSTP, MSTP) provide safe running

of the network using redundant data paths in the event of a fault. The ITU-T G.8031/

G.8032 ring and linear protection switching feature set makes NL33 able to create

network ring scenarios with recovery time under 50 ms. Monitoring and diagnosis

functions, e.g., sFlow or SNMPv1, v2c, v3 are provided.

Wide-Range Power Supply

The EN 50155 compliant supply voltage range of 24 V DC to 110 V DC provides maximum

flexibility for using the switch.

Maintenance Free and Extremely Rugged

The NL33 is designed for fanless operation at temperatures ranging from -40 °C to

+70 °C (10 min @ +85 °C). The cooling fins serve as a heat sink for the internal

electronics. It is maintenance-free and developed specifically for rough environmental

conditions in rolling stock applications. Long-term availability until 2026 from product

start minimizes lifecycle management by making the system available at least for this

period of time.
