Accessing System Features During Startup
The following keystrokes provide access to system features during startup.
Keystroke Description
<F2> Enters the System Setup program. See "Using the System Setup
Program and UEFI Boot Manager" on page 45.
<F10> Enters System Services, which opens the Lifecycle Controller.
The controller allows you to access utilities such as embedded system
diagnostics. For information on Lifecycle Controller or any of the
Lifecycle Controller software components, see the Lifecycle
Controller documentation on the Dell Support website at
support.dell.com/manuals.
<F11> Enters the BIOS Boot Manager or the Unified Extensible Firmware
Interface (UEFI) Boot Manager, depending on the system’s boot
configuration. See "Using the System Setup Program and
UEFI Boot Manager" on page 45.
<F12> Starts Preboot eXecution Environment (PXE) boot.
<Ctrl><E> Enters the Baseboard Management Controller (BMC) or iDRAC
Configuration Utility, which allows access to the system event log
(SEL) and configuration of remote access to the system. For more
information, see the BMC or iDRAC user documentation.
<Ctrl><C> Enters the SAS Configuration Utility. For more information, see the
SAS adapter documentation.
<Ctrl><S> Enters the utility to configure NIC settings for PXE boot. For more
information, see the documentation for your integrated NIC.

Power Indicator Codes
1
The power supplies have an indicator that shows whether power is present or
whether a power fault has occurred.
• Not lit — AC power is not connected.
• Green — In standby mode, indicates that a valid AC source is connected
to the power supply, and that the power supply is operational. When the
system is on, it also indicates that the power supply is providing DC power
to the system.
• Amber — Indicates a problem with the power supply.
• Alternating green and amber — When hot-adding a power supply, this
indicates that the power supply is mismatched with the other power supply.
Replace the power supply that has the flashing indicator with a power supply
that matches the capacity of the other installed power supply.
