Dell PowerEdge 860: About Your System
About Your System: Dell PowerEdge 860
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
• 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.
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
and
Rack Installation Instructions
included with your rack solution
describe 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.
About Your System 9
• 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 29.
<F10> Opens the utility partition, allowing you to run the system diagnostics. See "Running the
System Diagnostics" on page 94.
<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.
<Ctrl+S> Option is displayed only if you have PXE support enabled through the System Setup Program
(see "Integrated Devices Screen" on page 34). 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.

button
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 29 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 system is on.
The indicator is off when the system is off and power is
disconnected from the system. The indicator blinks
when the system is on but in standby 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.
2 Diagnostic indicators (4) The diagnostic indicators aid in diagnosing and
troubleshooting the system. For more information, see
your Hardware Owner’s Manual.

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 29 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.

System Messages
System messages appear on the screen to notify you of a possible problem with the system. Table 1-4 lists
the system messages that can occur and the probable cause and corrective action for each message.
NOTE: If you receive a system message that is not listed in Table 1-4, check the documentation for the application
that is running when the message appears or the operating system's documentation for an explanation of the
message and recommended action.
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the
components inside the system. Before performing any procedure, see your Product Information Guide for complete
information about safety precautions, working inside the computer and protecting against electrostatic discharge.

System Beep Codes
If an error that cannot be reported on the screen occurs during POST, the system may emit a series of beeps
that identifies the problem.
NOTE: If the system boots without a keyboard, mouse, or monitor attached, the system does not issue beep codes
related to those peripherals.
If a beep code is emitted, write down the series of beeps and then look it up in Figure 1-6. If you are unable
to resolve the problem by looking up the meaning of the beep code, use system diagnostics to identify the
possible cause. If you are still unable to resolve the problem, see "Getting Help" on page 103.

Warning Messages
A warning message alerts you to a possible problem and prompts you to respond before the system
continues a task. For example, before you format a diskette, a message will warn you that you may lose all
data on the diskette. Warning messages usually interrupt the task and require you to respond by typing
y
(yes) or
n (no).
NOTE: Warning messages are generated by either the application or the operating system. For more information,
see the documentation that accompanied the operating system or application.
Diagnostics Messages
When you run system diagnostics, an error message may result. Diagnostic error messages are not
covered in this section. Record the message on a copy of the Diagnostics Checklist in "Getting Help" on
page 103, and then follow the instructions in that section for obtaining technical assistance.
26 About Your System
Alert Messages
Systems management software generates alert messages for your system. Alert messages include
information, status, warning, and failure messages for drive, temperature, fan, and power conditions. For
more information, see the systems management software documentation.
