Safety instructions
This documentation contains instructions which must be observed to ensure your own personal safety
and to avoid damage to devices and machinery.
■Certified usage
The device may only be employed for the purposes described in the catalog and technical
description, and only in conjunction with external devices and components recommended or
approved by the manufacturer. The product can only be operated correctly and safely if it is
transported, stored, installed and assembled properly and correctly. Furthermore, it must be operated
and serviced carefully.
■Qualification requirements for personnel
Qualified personnel as understood in this manual and the warning signs are persons who are familiar
with the setup, assembly, startup, and operation of this product and are appropriately qualified for
their job. This includes, for example, those persons who have been:
►trained or directed or authorized to switch on and off, to ground and to label power circuits and
devices or systems in accordance with current safety engineering standards;
►trained or directed in the care and use of appropriate safety equipment in accordance with the
current standards of safety engineering;
►trained in providing first aid.
■National and international safety regulations
□Make sure that the electrical installation meets local or nationally applicable safety regulations.
■Note on the CE marking
The EESX module is not intended for end users in accordance with item 2(1)b) of the EMC Directive
2004/108/EG. See also chapter 1.2 in “Guide for the EMC Directive 2004/108/EC (21st May 2007)”.
The manufacturer or distributor of the end device in which the EES was installed, is responsible for
adhering to the applicable EU directives, as well as the CE marking.
The EMC tests were performed in combination with the Evaluation Board.
■Maintenance
□When designing this device, Hirschmann was largely able to forego using wear parts. The parts
subject to wear are dimensioned to last longer than the lifetime of the product when it is operated
normally.
□Relays are subject to natural wear. This wear depends on the frequency of the switching
operations. Check the resistance of the closed relay contacts and the switching function
periodically according to the frequency of the switching operations.
□Hirschmann continually works on improving and developing their software. You should regularly
check whether there is a new version of the software that provides you with additional benefits.
You will find software information and downloads on the product pages of the Hirschmann
website.
■ESD guidelines
The media modules contain components highly sensitive to electrostatic fields. These components
can be easily destroyed or have their lives shortened by an electrical field or by a discharge caused
by touching the contacts. You can find more information about devices vulnerable to electrostatic
fields in IEC/TR 61340-5-2 (2007-08)
■Recycling note
After usage, this product must be disposed of properly as electronic waste, in accordance with the
current disposal regulations of your county, state and country.
■WARNING
Parts on EESX20/30 module or EESX-Evaluation-Board should not touched in operation!
Due to possible hot spots of electronical components –especially the case of integrated circuits.

About this Guide
This document provides technical specifications for the Embedded Ethernet Switch eXtended (EESX)
Evaluation-Board. It also illustrates hardware integration guidelines for a Hirschmann Embedded Ethernet
Switch eXtended (EESX) module. It describes the board level interfaces as well as the key operation
parameters. Additionally, it provides the necessary information for a developer to validate their application
design using the EESX-Evaluation-Board.
The information in this publication merely contain general descriptions or performance factors which,
when applied in an actual situation, do not always correspond with the described form and may be
amended by way of the further development of products. The desired performance factors shall only be
deemed binding if these are expressly agreed on conclusion of the contract. Please note that some
characteristics of the recommended accessory parts may differ from the appropriate product. This might
limit the possible operating conditions for the entire system.

1.2 Power supply
Connect the DC jack on the EESX-Evaluation-Board to a 24 VDC power supply. Connect pins (1, 4) of
the jack to +UE and the center pins (2, 3) of the jack to GND.
Figure 1-3: DC jack connection
The nominal voltage of the EESX-Evaluation-Board is 24V DC but also the EESX-Evaluation-Board can
be supplied with +18 V up to +30 V at UE1 and/ or UE2.
Supply the EESX-Evaluation-Board only inside this voltage range!
The Capacitance of C305 and C307 summed in the schematic should be at least 1000 uF at 24V power
supply to ensure faultless operation if voltage interruptions of 10 ms occur!

►Auto negotiation
►Auto polarity
►Auto crossing (if auto negotiation is activated)
►1000 Mbit/s full-duplex mode, only Ports 1 and 2 of EESX30
►100 Mbit/s half-duplex mode, 100 Mbit/s full-duplex mode
►10 Mbit/s half-duplex mode, 10 Mbit/s full-duplex mode

1.4 Fiber optic Ethernet Interface
The EESX-Evaluation-Board provides SFP cages for optical Fast Ethernet (100Base-FX) SFP
transceivers for every Ethernet port. Even EESX30 module supports additionally 1000BASE-FX for GE-at
Ports # 1 and 2.
An optical DSC (1*9) transceiver is available at FE-Port 1 and can be implemented at costumer’s design
for each FE-Port. (DSC transceiver at (Gigabit) GE-Ports are currently not supported by the software.)
Please contact the Hirschmann Service to order single DSC transceivers for your development. Find the
contact data of the service in the last chapter of this manual.
Figure 1-6: FE-Port 1 with DSC transceiver for 100Base-FX
1.5 Mode-switch Settings for Ethernet Ports
Each Fast Ethernet port (FE) can operate in either 10/100Base-TX (using RJ45 connectors) or 100Base-
FX mode (using the SFP port) selected by the two Mode-switches (see Figure 1-7). The Gigabit Ethernet
ports (GE) can operate in either 1000Base-TX or 100/1000Base-FX mode.
To change between TX and FX mode both switchover contacts of each port must be put to TX or FX
position.

Note: See chapter 3.4 for more information about setting the ports to TX or FX mode.
Note: Port mode changes are activated after resetting the device.

A serial data RS232 (V24_TxD/RxD) connection is available on the EESX-Evaluation-Board to provide
access to the EESX module. This enables you to set up a connection to the Command Line Interface
(CLI) and system monitor. For more information on the CLI functionality, refer to the Command Line
Interface (EES) Reference Manual.
The serial interface uses RS232 (V.24) without hardware handshake. A SubD9 connector is mounted on
the EESX-Evaluation-Board for this purpose.
RS232 socket pin description (SubD9 female):
►Pin 2 -> RxD (Data from the EESX-Evaluation-Board to the host)
►Pin 3 -> TxD (Data from host to Evaluation-Board)
