1. INTRODUCTION 
The MiCOM - DS Agile Ethernet range is designed to deal with the needs of a wide range of 
electrical plant. Emphasis has been placed on compliance with standards, scalability, 
modularity and open architecture. 
These features mean that DS Agile products can be used in applications, from the most 
basic to the most demanding. They also ensure interoperability with existing components. 
Alstom provides a range of Ethernet products such as switches, which take into account the 
compulsory requirements of electrical substations, including power supply and immunity to 
environmental constraints. 
We also provide solutions to specific requirements such as network redundancy 
management. 
The products can be used independently, or can be integrated to form a DS Agile system, 
which is a Digital Control System (DCS). 
1.1  MiCOM - DS Agile Switches Product Range 
Driven by calls from all over the world for advanced substation applications for Automation 
control and monitoring, Alstom is committed to provide a comprehensive range of Ethernet-
based products that respond to our customers' needs. 
 Standard Ethernet products rarely meet the constraints of electrical plants: environmental, 
power supply, redundancy, etc. 
The new MiCOM - DS Agile Hxxx series has been specifically tailored to respond to all of 
these requirements, and is compatible with the DS Agile system. The MiCOM - DS 
Agile Hxxx range is designed to address different kinds of architectures and installations. 
 It is split into six major ranges.  These are: 
−  DS Agile Hx3x  Ethernet Switches designed for Teaming architecture with fast 
port-switch.  
−  MiCOM Hx4x  Ethernet Switches designed for Simple Ethernet Star architecture 
−  MiCOM Hx5x  Ethernet Switches designed for Redundant Optical Ring 
architecture with fast Self-Healing technology  
−  MiCOM Hx6x  Ethernet Switches designed for Dual Ethernet Star architecture 
with Dual Homing technology 
−  DS Agile Hx7x  Ethernet Switches designed for GOOSE filtering functionality  
−  DS Agile Hx8x  Ethernet Switches designed for Parallel Redundant architecture 
with PRP Protocol. 
1.2  Naming of MiCOM - DS Agile Ethernet Switches 
The Ethernet devices naming convention depends on its mechanical features and the 
number of copper or optical ports. 
−  MiCOM - DS Agile H1xx  PCI Board (the power supply is from the PCI BUS) 
−  MiCOM - DS Agile H3xx  DIN mounting case and Redundant power supply 
−  MiCOM - DS Agile H6xx  19’’ Rack with up to 4 switches and Redundant power 
    supply
