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

Cost Optimized Design by Focusing to Essential Requirements


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).



FeaturesMCMC with redundancy support including active Carrier Manager election and re-discovery of active system
Shelf manager implementation for local management of single MicroTCA chassis
GbE managed L2 Switch
ConnectionsSystem Interconnect:
• Gigabit Ethernet: 12x 1000BASE-BX (SerDes) on Fabric[A], 1x 1000BASE-BX (SerDes) on MCH update Channel
• I2C: 12x IPMB-L to AMC Modules, 2x IPMB-0 [A:B] redundant to Power Modules and Cooling Units, 1x IPMB-L inter-MCH, 1x I2C to carrier FRU

Front Interfaces
• Gigabit Ethernet: One 1000BASE-T on RJ-45 connector
• Ethernet: One 10BASE-TX on RJ-45 connector
• Serial Port: One terminal port with RS-232 signaling on an RJ-45 connector
• Reset: One reset switch
• LEDs:
   • 12 Link LEDs (green) for each port on the Fabric[A], 1 Link LED (green) for the MCH update Channel,
   • 1 LED (green) for control purchase, 4 bicolor (red / green) LEDs to indicate system states,
   • 3 AMC management LEDs (Hot Swap, Out-of-Service, Health)
