Initial commissioning
2.1 Overview
Once you have installed and networked the PCU 50.5, you must set up a Windows
administrator account before the PCU 50.5 can be accessed from a remote TCU. In
headless mode, therefore make the configuration in an answer file (unattend.xml) before
switching on the PCU 50.5 for the first time.
The diagram shows an example workflow for initial commissioning. Further information is
provided in the accompanying legend tables.
Note
Do not switch off the PCU 50.5 Windows 7 hardware!
Loss of data may result on Windows-based systems if the system is not shut down properly
before it is disconnected from the power source. For technical reasons, data are still being
written to the SSD shortly after shutdown
To avoid loss of data, use a SITOP UPS module.
See Configuring the SITOP UPS module for use with the PCU Base Software (Page 29).
