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 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.
• 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.

10 About Your System
• 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 27.
<F10> Opens the utility partition, allowing you to run the system diagnostics. See "Running the System
Diagnostics" on page 114.
<F11> Enters the boot menu selection screen, allowing you to choose a boot device.
<F12> Initiates PXE boot.
<Ctrl+C> Option is displayed for some SAS controller expansion cards. Enters the SAS Configuration Utility,
which includes RAID configuration options. 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 expansion
card. For more information, see the documentation for your RAID card.
<Ctrl+S> Option is displayed only if you have PXE support enabled through the System Setup Program (see
"Integrated Devices Screen" on page 32). This keystroke allows you to configure NIC settings for
PXE boot. For more information, see the documentation for your integrated NIC.

5 USB connectors (2) Connects USB 2.0-compliant devices to the system.
6 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.
7 power light No light — The system is off.
Steady green — The system is powered on.
Steady amber — The power supply is probably good. Check the
diagnostic indicators to see if the specific problem is identified. See
"Diagnostics Indicator Codes" on page 15.
Blinking amber — The system is powering up.
• If the hard-drive indicator is off, the power supply may need to be
replaced.
• If the hard-drive indicator is on, the system board is faulty. Check
the diagnostic indicators to see if the specific problem is identified.
See "Diagnostics Indicator Codes" on page 15.
8 network link light Lights when the system is linked to a network.
9 diagnostic lights (4) Display light-pattern codes to assist in troubleshooting system
problems.

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.

14 About 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 27 for information about enabling, disabling, and
configuring I/O ports and connectors.
NIC Indicator Codes
The 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.

BIOS Update Attempt
Failed! Remote BIOS update attempt failed. Retry the BIOS update. If problem persists, see "Getting Help" on page 123.
CPUs with different cache
sizes detected! Microprocessors with different cache sizes are installed.
Ensure that all microprocessors have the
same cache size and that they are
properly installed. See "Microprocessor"
on page 73.
Decreasing available
memory Faulty or improperly installed memory modules.
See "Troubleshooting System Memory"
on page 103.
DIMM pairs must be matched
in size, speed, and
technology. The following
DIMM pair is mismatched:
DIMM x and DIMM y.
Mismatched or unmatched DIMMs
installed; faulty or improperly seated
memory module(s).
Ensure that all pairs of memory modules
are of the same type and size and that
they are properly installed. See
"Memory" on page 76. If the problem
persists, see "Troubleshooting System
Memory" on page 103.
DIMMs must be populated in
sequential order beginning
with slot 1. The following
DIMM is electrically
isolated: DIMM x.
The specified DIMM is inaccessible to
the system due to its location. DIMMs
must be populated in sequential order,
beginning with slot 1.
Populate 2 or 4 DIMMs sequentially
beginning with slot 1. See "Memory" on
page 76.
DIMMs should be installed
in pairs. Pairs must be
matched in size, speed,
and technology.
Mismatched or unmatched DIMMs
installed; faulty or improperly seated
memory module(s). The system will
operate in a degraded mode with
reduced ECC protection. Only
memory installed in channel 0 will be
accessible.
Ensure that all pairs of memory modules
are of the same type and size and that
they are properly installed. See
"Memory" on page 76. If the problem
persists, see "Troubleshooting System
Memory" on page 103.
Dual-rank DIMM paired with
Single-rank DIMM - The
following DIMM/rank has
been disabled by BIOS:
DIMM x Rank y
Mismatched DIMMs installed; faulty
memory module(s). The system has
detected a dual-rank DIMM paired
with a single-rank DIMM. The second
rank of the dual-rank DIMM will be
disabled.
