Kontron has added to its MicroTCA products with an MCH (Management Controller Hub).

The AM4901 MCH provides system management and Ethernet switching for up to 12 AdvancedMC modules. It contains an unmanaged BCM5396 Ethernet switch, which will simplify designs.

Typical applications are likely to include image processing in the industrial and medical sectors, industrial control systems, information systems for trains and simple communication systems without need for managed switches.

It is a single PCB with only one MCH tongue. It provides one GbE uplink on the front. On the edge connector there are 12x GbE for AMCs plus 1x GbE for MCH interlink.

As well as standard LED indicators, there are status LEDs for 12 AdvancedMC modules on the front, as well as RJ45 connectors for one FE management interface and one serial interface to access the management controller (MCMC).
