IPMI 2.0 comes standard on our newest line of Intel Xeon E3 and E5 servers. Among IPMI's many useful features is the ability to mount an ISO from a Windows share as a Virtual CD-ROM. Before following the steps in this guide, be sure you have the ISO for your new OS of choice available over a Windows share. 1) Login to your IPMI portal using the information you were given upon your server's turnup. 2) Navigate to Virtual Media -> CD-ROM Image 3) Enter the information for accessing the ISO on your Windows share. Share host: Enter the IP address or properly resolving hostname of the server where your ISO resides Path to image: Enter the path to your ISO. This path is of the form: \sharename\path\to\image The beginning of the value is the name of your Windows share and then the path to the ISO within that share. User (optional): if your Windows share requires a username and password for access, enter the username here. Password (optional): if your Windows share requires a username and password for access, enter the password here. 4) Once you've entered the necessary values, click You should see the following message if your settings were entered correctly: 5) After saving your configuration, you now need to mount the Virtual CD-ROM.

If you do not see "There is a disk mounted" under the CDROM and ISO Status section, please repeat step 3) and ensure your Windows share is accessible. 6) With your CD-ROM image mounted, we can now reboot the machine and boot from the image. Go back to the "System Information" page: 7) On the "System Information" page, select click on the IPMI remote console preview section to open up the Java application for accessing your server's console. 8) Once the Java application is loaded, select Macro -> Macro -> Ctrl Alt Del.
