  • Page 29 3M 89110-0001 WARNING If you connect power incorrectly, the module will almost certainly be damaged or destroyed. Such damage is not covered by the RTD warranty! Please verify connections to the module before applying power. Power is normally supplied to the cpuModule through the top or bottom PCIe connectors (CN1 or CN2). If you are placing the cpuModule onto a stack that has a PCIe/104 power supply, you do not need to make additional connections to supply power.

  • Page 30: Selecting The Stack Order For The Cma34Cr

    Selecting the Stack Order for the CMA34CR 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.

    Connecting to the Stack The bus connectors of the cpuModule are simply plugged onto a PC/104 stack to connect to other devices. Follow the procedure below to ensure that stacking of the modules does not damage connectors or electronics. WARNING Do not force the module onto the stack! Wiggling the module or applying too much pressure may damage it.

    Thermal Management The cpuModule has several thermal features which can be used to monitor and control the board’s temperature when extreme operating conditions are prevalent. Thermal Monitor The Thermal Monitor is a feature on the CMA34CR that automatically throttles the CPU when the CPU exceeds its thermal limit.

  • Page 74: Power Management

    Power Management The CMA34CR 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 low power modes including ACPI configurations. Various wake options are also available to resume normal system power.

    RTD modules installed in IDAN frames are called building blocks. IDAN building blocks maintain the simple but rugged stacking concept of PC/PCI-104 and PCIe/104. Each RTD module is mounted in its own IDAN frame and all I/O connections are brought to the walls of each frame using standard PC connectors.
