3.7 System Monitor

The ADM-PCIE-9V3 has the ability to monitor temperature, voltage, and current of the system to check on the
operation of the board. The monitoring is implemented using an Atmel AVR microcontroller.
If the core FPGA temperature exceeds 100 degrees Celsius, the FPGA will be cleared to prevent damage to the
card.
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 front panel or via the IPMI interface available at the PCIe card
edge.
