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).

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_Presenceappears, 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.  
32  
About Your System  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
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.

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  
The system diagnostic utilities produce messages from diagnostic tests run on  
your system. See "Running the System Diagnostics" on page 167 for more  
information about system diagnostics.  
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.

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.

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).

Before You Begin  
NOTICE: Before you attempt to remove or install a drive while the system is  
running, see the documentation for the optional SAS RAID controller card to ensure  
that the host adapter is configured correctly to support hot-plug drive removal and  
insertion.  
NOTE: It is recommended that you use only drives that have been tested and  
approved for use with the SAS backplane board.  
You may need to use different programs than those provided with the  
operating system to partition and format the hard drives.  
NOTICE: Do not turn off or reboot your system while the drive is being formatted.  
Doing so can cause a drive failure.

When you format a high-capacity hard drive, allow enough time for the  
formatting to be completed. Long format times for these drives are normal.  
Configuring the Boot Device  
If you plan to boot the system from a hard drive, the drive must be attached  
to the primary (or boot) controller. The device that the system boots from is  
determined by the boot order specified in the System Setup program.  
The System Setup program provides options that the system uses to scan for  
installed boot devices. See "Using the System Setup Program" on page 43 for  
information about the System Setup program.

4
If the system is connected to a PDU or UPS, turn the PDU or UPS off and  
then on.  
If the PDU or UPS is not receiving power, plug it into another electrical  
outlet. If it still is not receiving power, try another PDU or UPS.  
Reconnect the system to the electrical outlet and turn on the system.  
If the system still is not working properly, see "Troubleshooting Power Supplies"  
on page 154.  
Checking the Equipment  
This section provides troubleshooting procedures for external devices  
attached to the system, such as the monitor, keyboard, or mouse. Before you  
perform any of the procedures, see "Troubleshooting External Connections"  
on page 144.  
Troubleshooting External Connections  
Loose or improperly connected cables are the most likely source of problems  
for the system, monitor, and other peripherals (such as a printer, keyboard,  
mouse, or other external device). Ensure that all external cables are securely

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
2
Check the system and power connections to the monitor.  
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.

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  
®
