On that memory card is only stored a boot environent, which does a handshake with the installation DVD belonging to the Scaleo and is executed on a client PC. Check
this FAQ on the Fujitsu website for details.
It is recommended to copy the content of this DVD to the clients disk and to uninstall the Home Server Connector on that client.
If you don't have the DVD any more, you may have to contact the Fujitsu product support.
Best greetings from Germany
