3.7 System Monitor

The ADM-PCIE-8K5-FH monitors temperature, voltage, and current of the board to check on the operation of the
board. The monitoring is implemented using an Atmel AVR microcontroller. All readings and measurements are
available to the FPGA, enabling detailed power consumption reporting.
Control algorithms within the microcontroller automatically check line voltages and on board temperatures and
shares makes the information available to the FPGA over a dedicated serial interface built into the Alpha Data
reference design package (sold separately). The information can also be accessed directly from the
microcontroller over the USB interface on the upper USB port on the front panel or via the IPMI interface
available at the PCIe card edge.

3.7.1 Automatic Temperature Monitoring

Automatic over-temperature shutdown was added as a function external to the FPGA from sn409 and onwards.
The over-temperature shutdown function will clear the FPGA program if the die temperature exceeds 100
degrees Celsius.
