Mammomat Fusion - Service

Hello everyone, one of my costumers recently bought one Mammomat Fusion System. It's not yet installed but I'd like to prepare myself before it arrives. I know it will be nowhere near as plug and play because it's a used equipment. Also, there will be DICOM nodes to update, networking and probably detector calibration. Can someone help me get through this?
Any manuals, procedures, password and alike will be greatly appreciated.
Thanks in advance.
