About Your System 9
About Your System
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
• 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.
Other Information You May Need
CAUTION: The Product Information Guide provides important safety and regulatory information. Warranty
information may be included within this document or as a separate document.
• The Rack Installation Guide or Rack Installation Instructions included with your rack solution
describes how to install your system into a rack.
• The
Getting Started Guide provides an overview of system features, setting up your system, and
technical specifications.
• CDs included with your system provide documentation and tools for configuring and managing
your system.
• Systems management software documentation describes the features, requirements, installation,
and basic operation of the software.
• Operating system documentation describes how to install (if necessary), configure, and use the
operating system software.
• Documentation for any components you purchased separately provides information to configure
and install these options.

10 About Your System
• Updates are sometimes included with the system to describe changes to the system, software, and/or
documentation.
NOTE: Always check for updates on support.dell.com and read the updates first because they often
supersede information in other documents.
• Release notes or readme files may be included to provide last-minute updates to the system or
documentation or advanced technical reference material intended for experienced users or
technicians.
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 23.
<F10> Enters the System Diagnostics program. See "Running the System Diagnostics" on page 86.
<F11> Enters the boot mode selections screen, allowing you to choose a boot device.
<F12> Exits PXE boot.
<Ctrl+E> Enters the Baseboard Management Controller (BMC) Setup Module, 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 optional 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 28). This keystroke allows you to configure NIC settings for
PXE boot. For more information, see the documentation for your integrated NIC.

1 Power-on indicator, power
button
The power button controls the DC power supply output
to the system.
NOTE: If you turn off the system using the power button
and the system is running an ACPI-compliant operating
system, the system performs a graceful shutdown before
the power is turned off. If the system is not running an
ACPI-compliant operating system, the power is turned off
immediately after the power button is pressed.
2 NMI button Used to troubleshoot software and device driver errors
when using certain operating systems. This button can
be pressed using the end of a paper clip.
Use this button only if directed to do so by qualified
support personnel or by the operating system's
documentation.
3 System identification button The identification buttons on the front and back panels
can be used to locate a particular system within a rack.
When one of these buttons is pushed, the blue system
status indicator on the front and back blinks until one of
the buttons is pushed again.

4 Diagnostics indicator lights (4) The four diagnostic indicator lights on the system front
panel display error codes during system startup.
5 System status indicator light Lights blue during normal system operation.
Both the systems management software and the
identification buttons located on the front and back of
the system can cause the indicator to flash blue to
identify a particular system.
Lights amber when the system needs attention due to a
problem.

Back-Panel Features and Indicators
Figure 1-2 shows the controls, indicators, and connectors located on the system's back panel.
Figure 1-2. Back-Panel Features and Indicators
Connecting External Devices
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.
• Always attach external devices while your system is turned off. Next, turn on any external devices
before turning on the system (unless the documentation for the device specifies otherwise).
For information about individual connectors, see "Jumpers and Connectors" on page 89. For information
about enabling, disabling, and configuring I/O ports and connectors, see "Using the System Setup Program"
on page 23.
Power Indicator Codes
The power button on the front panel controls the power input to the system's power supply. The power
indicator can provide information on power status (see
Figure 1-1 ). Table 1-3 lists the power button
