This section describes the physical, firmware, and software interface features
that provide and ensure the essential functioning of your system. The
physical connectors on your system’s front and back panels provide
convenient connectivity and system expansion capability. The system
firmware, applications, and operating systems monitor the system and
component status and alert you when a problem arises. System conditions
can be reported by any of the following:
•Front or back panel indicators
•System messages
•Diagnostic indicator codes
•Beep codes
•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
KeystrokeDescription
<F2>Enters the System Setup program. See "Using the System Setup
Program" on page 35.
<F10>Opens the utility partition, allowing you to run the system
diagnostics. See "Running the System Diagnostics" on page 118.
<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+R>Enters the RAID configuration utility, which allows you to configure
an optional RAID card. For more information, see the documentation
for your RAID card.

KeystrokeDescription
<Ctrl+S>Option is displayed only if you have PXE support enabled through the
System Setup Program (see "SATA Configuration Screen" on page 40
for options and descriptions for the information fields that appear on
the SATA Configuration screen). This keystroke allows you to
configure NIC settings for PXE boot. For more information, see the
documentation for your integrated NIC.
<Ctrl+D>If you have the optional Dell Remote Access Controller (DRAC), this
keystroke allows access to selected DRAC configuration settings. See
the DRAC User’s Guide for more information on setup and use of
DRAC.
Front-Panel Features and Indicators

The power button turns system power off
and on.
NOTICE: If you turn off the system
using the power button and the
system is running an ACPI-compliant
operating system, the system can
perform an orderly shutdown before
power is turned off. If the power
button is pressed for more than
4 seconds, the system power will turn
off regardless of the current
operating system state. If the system
is not running an ACPI-compliant
operating system, power is turned off
immediately after the power button is
pressed.
The power button is enabled in the
System Setup program. When disabled,
the button can only turn the system
power on. For more information, see
"Using the System Setup Program" on
page 35 and the operating system's
documentation.
The power-on indicator lights or blinks to
indicate the status of power to the system.
The power-on indicator lights when the

state, or when the system is off but is still
connected to the power source.
To exit from the standby state, briefly
press the power button.

Back-Panel Features and Indicators
Figure 1-2 shows the controls, indicators, and connectors located on the
system's back panel.
When connecting external devices to your system, follow these guidelines:
•Most devices must be connected to a specific connector and device drivers
must be installed before the device operates properly. (Device drivers are
normally included with your operating system software or with the device
itself.) See the documentation that accompanied the device for specific
installation and configuration instructions.
18About Your System
•Always attach an external device while your system and the device are
turned off. Next, turn on any external devices before turning on the system
(unless the documentation for the device specifies otherwise).
See "Using the System Setup Program" on page 35 for information about
enabling, disabling, and configuring I/O ports and connectors.
NIC Indicator Codes
Each NIC on the back panel has an indicator that provides information on
network activity and link status. See Figure 1-3. Table 1-3 lists the NIC
indicator codes.
