1.2 General Safety Precautions

• Service personnel must know the necessary electrical safety, wiring and connection practices for installing this equipment.
• Install this equipment only in compliance with local and national electrical codes.

1.3 References and Architecture Specifications

2 Introduction

COM Express® is a PICMG® standard that describes a COM (Computer-On-Module) and the supporting Carrier Board.
• The COM contains the processor, RAM, and I/O ICs.
• The Carrier Board provides power to the COM, additional I/O ICs, and all of the I/O connections.
Together the COM and Carrier Board make a bootable computer.
The electrical and mechanical interface between the COM and Carrier Board has several “Type” definitions. The user can select a COM and Carrier Board with an interface Type that matches their requirements.

2.1 Schroff Embedded COM System

The Schroff Embedded COM Systems combine Schroff COM Carrier boards and COM Express Type 6 modules in an Interscale case with convection cooling including a power board with 18 VDC - 26,4 VDC input voltage.
