Component Description OM6040

The topology of the OM6040 backplane permits a wide range of module configurations. There
are, however, some restrictions as to the use of particular module combinations.
If, for example, CPU modules are installed in both slots 1 and 2 (or 3 and 4), there must be no
SATA functionality active on AMC ports 2 and 3. If both CPUs have SATA active on these ports,
neither of the CPUs will not properly boot.
If PCIe functionality is implemented, by default, slot 1 is configured as the root complex. This
can be changed by setting appropriate PCIe configuration parameters in the MCH.
2.3 MicroTCA Carrier Hub - MCH
The OM6040 is supplied with an appropriate MCH installed at the factory. There are three pos-
sible configrations which must be specified at the time the OM6040 is ordered.
There is a base MCH which supports only GbE Fabric, the second version supports GbE and
PCIe, and the third version provides GbE and SRIO.
