Commissioning a System

Delivery condition of the system

Scope of validity
This document is valid for all systems that are supplied with Linux as operating system on
the CF card, such as all NCUs of the type NCU 7x0, PCU 321 etc.
Structure and contents of the CF card
A Linux partition as well as a FAT partition are available on the CF card. The memory space
of the CF card is occupied mainly by the LINUX EXT3 partition containing the system
software and the user data. A 2MB large FAT partition still exists but only for internal
administration purposes.
When the system is in operation, the following directories (this is a selection and not a
complete list) are available in the EXT3 partition on the CF card:
Directory
/siemens
/addon
/oem
/user
/system
/user/system/etc
/user/common/tcu
/var/log/messages
Files in the directory under /user always have priority over files with the same name in the
directory /oem → /addon → /siemens.
NCU Operating System (IM7)
