How to install Window server 2003 x64on server HP RX7640

Dear Support Team,

Now I have one HP RX7640 server which was installed Suse Linux Enterprise for along time, and now I want to reinstall it with new OS "Microsoft Window Server 2003 Enterprise x64" for other purpose. I get some issue when trying to reinstall it

1. I connect to the server with ILO interface and try to change the order booting as DVD device and reboot it

The message is dislayed "Load of Optiarc DVD  failed: Not Found"
