Yet another sticker with a number on it, possibly interesting to Fujitsu-Siemens in handling the software license refund process. The sticker on the bottom tells me I need to have a computer with Windows XP or Vista to use this product. That is of course untrue, you only need Windows if you run Windows on the server. As I don't have Windows and do not intend to install it I need to run another operating system on this server as well. That is why I removed the pre-installed software from the machine and requested a refund for the license fees.
