Intelligent Platform Management Controller (IPMC) for ATCA Compute Nodes * — •Johannes Lang — II. Physikalisches Institut JLU Giessen for the HADES, BESIII and PANDA collaboration

Future experiments like PANDA will create a large amount of data which has to be processed online. For this purpose a high performance FPGA based Compute Node is being developed in Giessen. This device, compatible with the ATCA standard (Advanced Telecommunication Computing Architecture), will be used for the upgrade of the BESIII and HADES DAQ systems as well as for the data acquisition and trigger of the PANDA experiment.

ATCA specifications require a slow control manager (IPMC) for every ATCA compliant device. Our realization consists of a microcontroller based add on card procuring shelf communication via I2C. It manages power negotiation & airflow and monitors voltages, status & component temperatures. A connection to the front panel allows to display basic information and to directly execute tasks like reset, hot swap or initialization of certain boot modes. The implementation of the IPMC will be presented.
