Preparing for installation

Logging in to the server

You can log in to the server through KVM or the HDM remote console.

Preparing an OS image

Before installing an OS, obtain an OS image from the official website of the OS, and then connect the
boot media that contain the OS image to the server.
•
For KVM login, you can use an optical disk drive, bootable USB disk, or PXE server as the boot
media. Using a PXE server as the boot media is applicable to batch OS installation.
•
For HDM login, you can use an optical disk drive, bootable USB disk, PXE server, or virtual
media (virtual disk, CD/DVD, or drive/USB) as the boot media.
Prepare an OS image as shown in the following table.
