  • Page 31: Selecting The Stack Order For The Cmx34Kb/Cma34Kb

    Selecting the Stack Order for the CMX34KB/CMA34KB There are several things to consider when selecting the order of boards in the stack. Before selecting the order, be sure to determine which bus connector on each board is the “Active” bus. Typically, if a peripheral module has both PCIe and PCI bus connectors, only the PCIe is active, and the PCI is pass-through.

  • Page 32: Stack Example

    The figure below shows an example of a complete system stack. Most systems will be a subset of this example. This example stack may be further expanded with PCIe-to-PCIe bridges or a PCIe to PCI bridge. Figure 4 System Stacking Example CMX34KB/CMA34KB User’s Manual BDM-610000089 Rev B...

    Upon entering the Critical Trip state, the operating system will issue a command to the processor, and the CMX34KB/CMA34KB will immediately transition to the S5 (Soft-Off) ACPI power state. To exit the Critical Trip state (and S5), the CPU temperature must be reduced to a point that the internal thermal sensors are below the Critical Trip Point.

  • Page 71: Power Management

    Power Management The CMX34KB/CMA34KB cpuModule supports various powering mechanisms which allow the cpuModule to monitor power consumption and temperature and achieve minimal power consumption states. These unique features include thermal monitoring and thermal throttling, as well as ACPI low power modes. Various wake options are also available to resume normal system power.

  • Page 90: Appendix C Idan Dimensions And Pinout

    IDAN frame and all I/O connections are brought to the walls of each frame using standard PC connectors. On the CMA34KB, no connections are made from module to module internal to the system other than through the PCIe/104 Type 2 bus, enabling quick interchangeability and system expansion without hours of rewiring and board redesign.

    2.5” SATA interface to the first SATA link on the CPU’s top PCIe/104 Type 2 connector (CN1). Also, inside the IDAN-CMA34KB unit is a CMOS battery which is connected to the battery input connection of the cpuModule’s Utility Port 2.0 connector. The frame of the IDAN-CMA34KB brings out the cpuModule’s multi-color LED as well as the cpuModule’s reset button.
