Description of the DP and its components CDR – Internal Interfaces – Michel Dupieux8 The DP functionality is obtained by connecting different specialized items, which form a complex system. The main subassembly items are:  Control Cluster Board (CCB)  Main processing unit (CPU)  Data Storage (DST)  Housekeeping system (HK)  Clock Board (CLKB)  GPS receiver (GPSR)  Data Processor Power Supplies (DP-LVPS1-2-3)  PDM Power Supply (PDM-LVPS)

Complete list of cables CDR – Internal Interfaces – Michel Dupieux12

Status on Internal & External Interfaces Internal Interfaces All the interfaces have been checked with the sub-system responsibles. A list of the key points verification is done below: - All interfaces were checked - All connectors pinout were checked - Each Pin on each connector was checked - Each Sub-system have its own cables and connectors lists. - All the cables on both side were checked - Connectors and cables have single reference - One responsible for each cable is done - Maximum Use of Female connector on Front panel - Use Female connectors on power side. External Interfaces On the external interfaces the same work has been done CDR – Internal Interfaces – Michel Dupieux13
