Kontron AM4901 - Cost optimized MCH (MicroTCA Carrier Hub) with Switch

Cost Optimized Design by Focusing to Essential Requirements

Introduction

The AM4901 represents a MicroTCA compliant MCH with a cost improved design. It supports the Kontron family of cost optimized MicroTCA platforms, as well as a range of other 3rd party platforms.

The two main functions of an MCH are system management (i.e. IPMI controlled power management, electronic keying, hot-swap of AMCs) and Ethernet switching. The AM4901 contains an unmanaged BCM5396 Ethernet switch, which allows to simplify the design and to improve costs (lower cost components, no switch controller, no software for switch controller).
