A TI MSP432 satellite controller resides on the U55C card to control and monitor voltages, currents and temperatures. The host server board management controller (BMC) can interact with the satellite controller to monitor and control U55C cards through out-of-band communication. Xilinx supports the PLDM protocol over MCTP over SMBUS, complying with DMTF standards. Refer to the Alveo Card Out-of-Band Management Specification for Server BMC (XD038) for more information. When used with the Xilinx provided platform, you can easily monitor for any abnormal operating conditions and react accordingly. If you are not using the platform, Xilinx provides a Card Management Solution IP allowing you to quickly develop and interact with the satellite controller from the FPGA. See the Card Management Solution Subsystem Product Guide (PG348) for more information.
