The switch-over procedure is started and subsequently verified.
When the switch-over procedure has been successfully completed, the following message is dis-
played on the screen:
● Confirm the message with OK. The data are now saved to the local data storage.
If the switch-over procedure could not be performed, a corresponding error message is displayed.
Switching from local to central data storage:
NOTE
Prerequisite for the switch-over operation is the existence of a central data storage.
If the latter does not exist yet, it will not be set up.
● Click on the Data storage menu option on the SERVICES menu on the desktop.
The "Data storage" window is opened..
● Click on the Central data access button.
● Click on the entry field and enter the pathname of the central data storage.
NOTE
Below the path of the central data storage the "Master data" and "Job data" directories must be
located (e.g. /nfs/zentral_dat/zentral_sdh/Master data; ..../zentral_sdh/Job data).
● Click on OK.
The dialog box containing a listing of the prerequisites to be fulfilled for the switch-over operation
is opened.
● If all conditions are met, click on the OK button.
The switch-over procedure is started and subsequently verified. If it is not possible to access the
central data storage, the following error message is displayed.

● Click on OK, eliminate the error and subsequently re-start the switch-over procedure, as described
above.
Once the switch-over procedure has been completed successfully, a corresponding message is
displayed on the screen.
● Acknowledge the message by choosing OK. The data are now saved to the central data storage.
Procedure in the event of a power failure with central data storage activated:
If a power failure has occurred, the system will inform you of this situation by displaying a warning
message on the screen together with instructions how to proceed further.
First check whether the power failure will presumably last for some time or whether power can be
restored quickly.
In the event of a short-time power failure, you can proceed as follows:
● Allow the current job to be completed.
● If the line computer is in the "control mode", finish the line computer session via the main menu by
selecting LC_End and subsequently re-start by selecting LC_Start.
(This is not required in the programming mode).
● When power has been restored, continue the assembly by means of the central data.
In the event of a power failure over an extended period of time, you can proceed as follows:
● Switch the data storage to local data access.
● If the line computer is in the "control mode", finish the line computer session via the main menu by
selecting LC_End and subsequently re-start by selecting LC_Start.
(This is not required in the programming mode).
● If necessary, copy the data from the central storage to the local line computer using a streamer
tape.
● Continue the assembly by means of the local data.

4.3 User Interface of the Data Manager
4.3.1 General Description
The window-oriented user interface which is capable of handling several data partners (see Fig. 4.3.1)
is used for manipulating the files and file structures within the line computer system.
The data partners must have been logged on in the Data Manager.
4.3.2 Starting the Data Manager
● Click on FILE -> Data Manager on the desktop menu bar.
The main window of the Data Manager with all data partners logged into the Data Manager is
opened (see Fig. 4.3.1).
NOTE
If the user selects menu option OPTIONS --> Save default values
(see page 4 - 13) in the main window, the main window and all open file windows (incl. paths, posi-
tions, display mode) are saved to a configuration file, ensuring that all thus stored windows will be
automatically opened the next time the line computer is started up again, provided the respective
data partners can be addressed.
