power supply and that the power supply is operational.

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 with the exception of Titanium power supplies, which support only 220 V. 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.

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 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.
