Kontron AM4904 / AM4910 - High-End MicroTCA Carrier Hub (MCH)

With Enterprise Class Ethernet Switching Specifications


The Enterprise-Class AM4904 / AM4910 MCH provides the central management and data switching entity for all kind of MicroTCA platforms.

To fit to the different needs of various applications the AM4904/AM4910 comes in four versions, (1) as a pure Gigabit Ethernet switching MCH (AM4904-BASE), in combination with (2) sRIO (AM4904-SRIO), or (3) PCIe switching (AM4904-PCIE) and (4) the highest bandwidth offering 10 Gigabit Ethernet switching (AM4910).

The powerful 600MHz processor for MCMC functionality and switching management enables a highly efficient MCH implementation for up to 12 AMCs, 2 cooling units and 4 power units and for usage in applications requiring a redundant architecture. Furthermore the support of Rear I/O functionality according to MTCA.4 is implemented. A sophisticated clock implementation provides various Telco clocks and the PCI Express Fabric Clocking distribution.

Designed to support Enterprise-Class fully-managed Layer2 switching capabilities the AM4904/AM4910 provides Quality-of-Service functionality like Traffic Priorization, Access Control and Multi-Cast including full 4K VLAN, Link Aggregation - to name just a few. The Layer3 management capabilities can be offered on project request.
