3.1. Health Monitoring Features
The Intel® FPGA PAC incorporates sensors that allow the host server to read telemetry data from the board such as voltage, current, power, temperatures and network status information from various components on the board. This telemetry data is available via the PLDM interface or over PCIe using the fpgainfo tool available with the Intel Acceleration Stack. These sensors reside on the I2C busses that are connected to the Board Management Controller (BMC) and FPGA device.
Note: The FPGA VCC Core power has a dedicated AVSbus that is separate from any of the I2C busses.
Note: The QSFP Network ports reside behind the network port controller. See the controller datasheet (Texas Instruments FPC202RHUR) for more information.
Note: The FPGA design can read these sensors directly or through the Board Management Controller using standard PLDM commands and report their status to the host server.
