Using USB Diskette Or USB DVD/CD Drives
The server module has USB ports on the front which allow 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 server module.
NOTE: Your server module supports only Dell-branded USB 2.0 drives. 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 and set the drive as first in the boot sequence. 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. You can also select the boot device by
pressing during system start-up and selecting a boot device for the current boot sequence.
Hard-Drive Indicator Patterns
Your system supports two 2.5 inch SSD, SAS or SATA hard drives.
NOTE: SSD/SAS/SATA hard drives cannot be mixed within a server module.
The hard-disk drives plug into the hard-drive backplane inside the server module. On server modules with a diskless
configuration, all hard drive slots must be filled with hard-drive blanks, and the hard-drive backplane must still be
installed to maintain proper airflow.
The hard-drive indicators display different patterns as drive events occur in the system.
