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).

About Your System

LCD Status Messages
The system's control panel LCD provides status messages to signify when the
system is operating correctly or when the system needs attention.
The LCD lights blue to indicate a normal operating condition, and lights
amber to indicate an error condition. The LCD scrolls a message that
includes a status code followed by descriptive text. Table 1-7 lists the LCD
status messages that can occur and the probable cause for each message. The
LCD messages refer to events recorded in the System Event Log (SEL). For
information on the SEL and configuring system management settings, see
the systems management software documentation.
CAUTION: Only trained service technicians are authorized to remove the system
cover and access any of the components inside the system. See your Product
Information Guide for complete information about safety precautions, working
inside the computer, and protecting against electrostatic discharge.
NOTE: If your system fails to boot, press the System ID button for at least five
seconds until an error code appears on the LCD. Record the code, then see "Getting
Help" on page 179.

Solving Problems Described by LCD Status Messages
The code and text on the LCD can often specify a very precise fault condition
that is easily corrected. For example, if the code
E0708 PROC_1_Presence appears, you know that a microprocessor is
not installed in socket 1.
In contrast, you might be able to determine the problem if multiple related
errors occur. For example, if you receive a series of messages indicating
multiple voltage faults, you might determine that the problem is a failing
power supply.

Removing LCD Status Messages
For faults associated with sensors, such as temperature, voltage, fans, and so
on, the LCD message is automatically removed when that sensor returns to a
normal state. For example, if temperature for a component goes out of range,
the LCD displays the fault; when the temperature returns to the acceptable
range, the message is removed from the LCD. For other faults, you must take
action to remove the message from the display:

•

Clear the SEL — You can perform this task remotely, but you will lose
the event history for the system.

•

Power cycle — Turn off the system and disconnect it from the electrical
outlet; wait approximately ten seconds, reconnect the power cable, and
restart the system.

About Your System

Any of these actions will remove fault messages, and return the status
indicators and LCD colors to the normal state. Messages will reappear under
the following conditions:
•

The sensor returns to a normal state but fails again, resulting in a new
SEL entry.

•

The system is reset and new error events are detected.

•

A failure is recorded from another source that maps to the same display
entry.

System Messages
System messages appear on the screen to notify you of a possible problem
with the system. Table 1-8 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 1-8, 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. See your Product
Information Guide for complete information about safety precautions, working
inside the computer, and protecting against electrostatic discharge.

System Memory
You can upgrade your system memory to a maximum of 128 GB (twoprocessor configurations) or 256 GB (four-processor configurations) by
installing sets of 512-MB, 1-GB, 2-GB, 4-GB, or 8-Gb (when available)
memory modules. 667-MHz registered DDR-II memory modules are
supported in all memory sizes. 2-GB and 4-GB (when available) 800-Mhz
memory modules are also supported in restricted configurations.
Sixteen memory sockets are located on the system board under the cooling
shroud assembly. In four-processor systems, sixteen additional sockets are
located on the processor expansion module board (PEM). Each processor has
two memory channels, organized in sets of four memory module slots per
channel.

Installing System Components

Your system hardware supports Non-Uniform Memory Architecture (NUMA).
Each processor has its own memory controller and local memory for reduced
access times, but it can also access memory from another processor. This
architecture improves system performance if an operating system is installed
that supports this feature.
NOTICE: To enable NUMA, run the System Setup program and disable the Node
Interleaving option. See "Using the System Setup Program" on page 43.

General Memory Module Installation Guidelines
To ensure optimal performance of your system, observe the following
guidelines when configuring your system memory.
•

Memory modules must be installed in pairs, beginning with the first two
sockets in each set of memory modules. These sockets are marked by white
retention levers.

•

All memory modules must be identical in speed and technology. The two
memory modules in each pair must be the same size.

Memory can either be installed in a two-processor configuration (Table 3-1)
or a four-processor configuration (Table 3-2).

Troubleshooting Your System

attached to the external connectors on your system. See "Front-Panel
Features and Indicators" on page 13 and "Back-Panel Features and Indicators"
on page 18 for the front- and back-panel connectors on your system.

Troubleshooting the Video Subsystem
Problem

•

Monitor is not working properly.

•

Video memory is faulty.

Action

1 Check the system and power connections to the monitor.
2 Determine whether the system has an expansion card with a video output
connector.
In this system configuration, the monitor cable should normally be
connected to the connector on the expansion card, not to the system’s
integrated video connector.
To verify that the monitor is connected to the correct video connector,
turn off the system and wait for 1 minute, then connect the monitor to the
other video connector and turn the system on again.
3 Determine whether the system has monitors attached to both the front
and back video connectors.
The system supports only one monitor attached to either the front or back
video connector. When a monitor is connected to the front panel, the
back-panel video connector is disabled.
If two monitors are attached to the system, disconnect one monitor. If the
problem is not resolved, continue to the next step.
4 Run the appropriate online diagnostic test. See "Using Dell PowerEdge
Diagnostics" on page 167.
If the test runs successfully, the problem is not related to video hardware.
If the test fails, see "Getting Help" on page 179.

Troubleshooting Your System

145

Running the System Diagnostics
If you experience a problem with your system, run the diagnostics before
calling for technical assistance. The purpose of the diagnostics is to test your
system's hardware without requiring additional equipment or risking data
loss. If you are unable to fix the problem yourself, service and support
personnel can use diagnostics test results to help you solve the problem.

Using Dell PowerEdge Diagnostics
To assess a system problem, first use the online Dell™ PowerEdge™
Diagnostics. Dell PowerEdge Diagnostics is a suite of diagnostic programs, or
test modules, that include diagnostic tests on chassis and storage components
such as hard drives, physical memory, communications and printer ports,
NICs, CMOS, and more. If you are unable to identify the problem using the
PowerEdge Diagnostics, then use the system diagnostics.
The files required to run PowerEdge Diagnostics for systems running
supported Microsoft® Windows® and Linux operating systems are available
at support.dell.com and on the CDs that came with your system. For
information about using diagnostics, see the Dell PowerEdge Diagnostics
User's Guide.
