Using USB Diskette or USB DVD/CD Drives
The blade 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 blade.
NOTE: Your blade 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 <F11> during system start-up and selecting a boot device for the current boot sequence.
Hard-Drive/SSD Indicator Patterns
The hard-drive/SSD indicators display different patterns as drive events occur in the system.

Using The System Setup And Boot Manager
System Setup enables you to manage your system hardware and specify BIOS-level options.
The following keystrokes provide access to system features during startup:
Keystroke Description
<F2> Enters the System Setup.
<F10> Enters System Services, which opens the Dell Lifecycle Controller 2 (LC2). The Dell LC2 supports systems
management features such as operating system deployment, hardware diagnostics, platform updates, and
platform configuration, using a graphical user interface. The exact LC2 feature set is determined by the
iDRAC license purchased. For more information, see the Dell LC2 documentation.
<F11> Enters the BIOS Boot Manager or the Unified Extensible Firmware Interface (UEFI) Boot Manager,
depending on the system's boot configuration.
<F12> Starts Preboot eXecution Environment (PXE) boot.
From the System Setup, you can:
• Change the NVRAM settings after you add or remove hardware
• View the system hardware configuration
• Enable or disable integrated devices
• Set performance and power management thresholds
• Manage system security
You can access the System Setup using the:
• Standard graphical browser, which is enabled by default
• Text browser, which is enabled using Console Redirection
To enable Console Redirection, in System Setup, select System BIOS → Serial Communication screen → Serial
Communication, select On with Console Redirection.
NOTE: By default, help text for the selected field is displayed in the graphical browser. To view the help text in the
text browser, press <F1>.
Choosing The System Boot Mode
System Setup enables you to specify the boot mode for installing your operating system:
• BIOS boot mode (the default) is the standard BIOS-level boot interface.
• UEFI boot mode is an enhanced 64-bit boot interface based on Unified Extensible Firmware Interface (UEFI)
specifications that overlays the system BIOS.
You must select the boot mode in the Boot Mode field of the Boot Settings screen of System Setup. Once you specify the
boot mode, the system boots in the specified boot mode and you then proceed to install your operating system from that
11

mode. Thereafter, you must boot the system in the same boot mode (BIOS or UEFI) to access the installed operating
system. Trying to boot the operating system from the other boot mode will cause the system to halt at startup.
NOTE: Operating systems must be UEFI-compatible to be installed from the UEFI boot mode. DOS and 32-bit
operating systems do not support UEFI and can only be installed from the BIOS boot mode.
NOTE: For the latest information on supported operating systems, go to dell.com/ossupport.
Entering System Setup
1. Turn on or restart your system.
2. Press <F2> immediately after you see the following message:
<F2> = System Setup
If your operating system begins to load before you press <F2>, allow the system to finish booting, and then restart
your system and try again.
Responding To Error Messages
If an error message is displayed while the system is booting, make a note of the message. For more information, see
System Error Messages.
NOTE: After installing a memory upgrade, it is normal for your system to display a message the first time you start
your system.
Using The System Setup Navigation Keys
Keys Action
Up arrow Moves to the previous field.
Down arrow Moves to the next field.
<Enter> Allows you to type in a value in the selected field (if applicable) or follow the link in the field.
Spacebar Expands or collapses a drop-down list, if applicable.
<Tab> Moves to the next focus area.
NOTE: For the standard graphics browser only.
<Esc> Moves to the previous page till you view the main screen. Pressing <Esc> in the main screen displays a
message that prompts you to save any unsaved changes and restarts the system.
<F1> Displays the System Setup help file.
NOTE: For most of the options, any changes that you make are recorded but do not take effect until you restart the
system.
