problem arises. System conditions can be reported by any of the following:
• Front or back panel indicators
• LCD status messages
• System messages
• Warning messages
• Diagnostics messages
• Alert messages
This section describes each type of message, lists the possible causes, and provides steps to resolve
any problems indicated by a message. The system indicators and features are illustrated in this
section.

Accessing System Features During Startup
Table 1-1 describes keystrokes that may be entered during startup to access system features. If your
operating system begins to load before you enter the keystroke, allow the system to finish booting, and
then restart your system and try again.
Table 1-1. Keystrokes for Accessing System Features
Keystroke Description
<F2> Enters the System Setup program. See "Using the System Setup Program" on page 31.
<F10> Enters the System Diagnostics program. See "Running the System Diagnostics" on page 118.
<F11> Enters the boot mode selection screen, allowing you to choose a boot device.
<F12> Exits PXE boot.
<Ctrl+E> Enters the Baseboard Management Controller (BMC) Management Utility, which allows access to
the system event log (SEL). See the BMC User’s Guide for more information on setup and use
of BMC.
<Ctrl+C> Enters the SAS Configuration Utility. See your SAS adapter User’s Guide for more information.
<Ctrl+S> Option is displayed only if you have PXE support enabled through the System Setup Program (see
"Integrated Devices Screen" on page 36). This keystroke allows you to configure NIC settings for
PXE boot. For more information, see the documentation for the integrated NIC.
