Dell PowerEdge M420 Hardware Owner's Manual - Page 30

Using USB Diskette or USB DVD/CD Drives Each blade has USB ports on the front of the blade which allows you to connect a USB diskette drive, USB flash drive, USB DVD/CD drive, keyboard, or mouse. The USB drives can be used to configure the blade. NOTE: These blades support only Dell-branded USB 2.0 drives. The drive must be horizontal and level to operate properly. Use the optional external drive storage tray to support the drive while in use. NOTE: If the drive must be designated as the boot drive, connect the USB drive, restart the system, then enter the System Setup Program and set the drive as first in the boot sequence (see "Using the System Setup Program and UEFI Boot Manager" on page 127). The USB device is displayed in the boot order setup screen only if it is attached to the system before you run the System Setup program. You can also select the boot device by pressing during system start-up and selecting a boot device for the current boot sequence.
