Description of the DP and its components

CDR – 18.12.2012

Internal Interfaces – Michel Dupieux 8

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)

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
