1. Transfer, Relocation, and Disposal
1.1 Transfer to a Third Party
Observe the following precautions when you transfer (or sell) the server or software provided with the server to
a third party.
•Server
When transferring (or selling) the server to a third party, be sure to provide the server’s instruction manuals
(including electronic manuals) to the third party.
•Data on the hard disk drive
Be sure to erase the data stored in HDD to prevent the leakage of sensitive data (such as customer
information or company management information) to any third parties. It is the user’s responsibility to erase
the data.
Important
NEC assumes no liability for data leakage should the product be transferred
to a third party without erasing the data.
Data seems to be erased when you empty "Recycle Bin" of Windows or run the "format" command of the
operating system. However, the actual data remains on the hard disk drive. Data not erased completely
might be restored by special software and used for unexpected purposes.
•Bundled software
Observe the following precautions when transferring (selling) the bundled software to a third party.
– Transfer them with the server.
– All provided media and documents must be transferred and no backup copies must be retained.
– Transfer requirements listed in "Software License Agreement" that comes with each software application
must be satisfied.
– Software on client PC must be uninstalled before transferring.
