Intelligent Platform Management Controller (IPMC) for ATCA Compute Nodes * — •Johannes Lang¹, Ming Liu¹, Zhen'An Liu², Qiang Wang², Hao Xu², and Wolfgang Kühn¹ — ¹II. Physikalisches Institut, JLU Giessen — ²Institute for High Energy Physics, Beijing

The PANDA experiment with its high data rate presents a significant challenge for the trigger and data acquisition system. Therefore a main building block of the data processing concept, the Compute Node, has been designed and is currently being tested. It will also be used for the upgrade of the HADES trigger system and comprises 5 FPGAs and high bandwidth connections (RocketIO, Gigabit Ethernet) taking advantage of a new shelf standard originating from the telecommunication sector (the Advanced Telecommunication Computing Architecture (ATCA)). This standard requires each supported module to feature a dedicated control unit, the IPMC.

An implementation of such a controller, a micro-controller utilizing add-on card will be presented. It can be plugged into the Compute Node and communicates with a shelf manager via the I2C bus. Applications include negotiation of power levels, reading of sensor data for temperature, voltages and current. In addition, status and configuration of the FPGAs on the Compute Node can be checked and changed. First experience with a prototype board will be reported.
