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 EES 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 EES adheres to the EMC standards as listed in section 5.1 of this document. EES20 and EES25 5 Release 1.7 04/2020 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. 6 EES20 and EES25 Release 1.7 04/2020 About this Guide This document provides technical specifications for the Embedded Ethernet Switch (EES) development board. It also illustrates hardware integration guidelines for a Hirschmann Embedded Ethernet Switch (EES) 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 EES development 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. References On the EES Development Kit CD you can find additional documents for the development board. It is recommended to use these documents when developing your application. ► EES development board schematics in .PDF format ► EES development board schematics in ORCAD format ► EES development board Gerber files ► EES development board PCB layout files ► VHDL code of EES development board CPLD Legend The symbols used in this manual have the following meanings: ► Listing □ Work step ■ Subheading EES20 and EES25 7 Release 1.7 04/2020 Revision History Version Date Page Description 1.0 04/2012 New Create Preliminary 1.1 08/2012 26 Added - Alternative SPI implementation and assembly option 1.2 01/2013 20, 21, 22 Updated the applications and and 24 assembly notes for Tx- and Fx- Modes Added and updated - Switching 31, 32, 33 parameter Added - Electrical Specification: 34 Reduction of power Consumption Changed - Electrical Specification: 35 Fx- Mode: Input sensitivity to VI DIFF min. = 500mV 1.3 03/2013 22, 26 Application and assembly information changed 1.4 03/2013 28 Added - Host device connection over an Ethernet Interface Added - Capacitive and Magnetic 29,30 Coupling 1.5 06/2013 16 Added - Heat Spreader 20 - Note: Redundancy protocols 41 - MTBF Value 1.6 11/2016 22 Schematic for DSx-Transceiver modified 1.7 04/2020 21 removed confusing „(VCC3.3)“ in Table 3-1 22 removed a confusing recommendation 8 EES20 and EES25 Release 1.7 04/2020 1 Development Board Interfaces 1.1 Overview Figure 1-1: Components of the PCB Assembly The hardware development board offers: (1) DC Jack for 24 VDC external power supply (2) 6 * Magnetics + RJ45 connector for 10/100Base-TX.
