Indicator Indicator Code
Link and activity indicators are off The NIC is not connected to the network.
Link indicator is green The NIC is connected to a valid network at its maximum port speed (1 Gbps or 10
Gbps).
Link indicator is amber The NIC is connected to a valid network at less than its maximum port speed.
Activity indicator is blinking green Network data is being sent or received.
Power Indicator Codes
Each AC power supply has an illuminated translucent handle and each DC power supply (when available) has an LED
that serves as an indicator to show whether power is present or whether a power fault has occurred.

Power
Indicator
Pattern
Condition
Not lit Power is not connected.
Green The handle/LED indicator lights green indicating that a valid power source is connected to the power
supply and that the power supply is operational.
Flashing
amber
Indicates a problem with the power supply.
CAUTION: When correcting a power supply mismatch, replace only the power supply with the
flashing indicator. Swapping the opposite power supply to make a matched pair can result in an
error condition and unexpected system shutdown. To change from a High Output configuration to a
Low Output configuration or vice versa, you must power down the system.
CAUTION: AC power supplies support both 220 V and 110 V input voltages. When two identical
power supplies receive different input voltages, they can output different wattages, and trigger a
mismatch.
CAUTION: If two power supplies are used, they must be of the same type and have the same
maximum output power.
CAUTION: Combining AC and DC power supplies is not supported and triggers a mismatch.
Flashing
green
When hot-adding a power supply, this indicates that the power supply is mismatched with the other
power supply (in terms of efficiency, feature set, health status, and supported voltage). Replace the
power supply that has the flashing indicator with a power supply that matches the capacity of the
other installed power supply.
Other Information You May Need
WARNING: See the safety and regulatory information that shipped with your system. Warranty information may be
included within this document or as a separate document.
• The Getting Started Guide provides an overview of setting up your system, and technical specifications. This
document is available online at support.dell.com/manuals.
• The rack documentation included with your rack solution describes how to install your system into a rack, if
required.
• Any media that ships with your system that provides documentation and tools for configuring and managing your
system, including those pertaining to the operating system, system management software, system updates, and
system components that you purchased with your system.
NOTE: Always check for updates on support.dell.com/manuals and read the updates first because they often
supersede information in other documents.

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
17

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.
