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 127, and then follow
the instructions in that section for obtaining technical assistance.
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.

Using the System Setup Program
After you set up your system, run the System Setup program to familiarize
yourself with your system configuration and optional settings. Record the
information for future reference.
You can use the System Setup program to:
•Change the system configuration stored in NVRAM after you add, change,
or remove hardware
•Set or change user-selectable options—for example, the time or date
•Enable or disable integrated devices

System and Setup Password Features
NOTICE: The password features provide a basic level of security for the data on
your system. If your data requires more security, use additional forms of protection,
such as data encryption programs.
NOTICE: Anyone can access the data stored on your system if you leave the
system running and unattended without having a system password assigned or if
you leave your system unlocked so that someone can disable the password by
changing a jumper setting.
Your system is shipped to you without the system password feature enabled. If
system security is a concern, operate your system only with system password
protection.
To change or delete an existing password, you must know the password (see
"Deleting or Changing an Existing System Password" on page 47). If you forget
your password, you cannot operate your system or change settings in the System
Setup program until a trained service technician changes the password jumper
setting to disable the passwords, and erases the existing passwords. This
procedure is described in "Disabling a Forgotten Password" on page 125.

System Memory
The four memory module sockets are located on the system board adjacent to
the power supply and can accommodate 512 MB to 8 GB of unbuffered ECC
PC-5300/6400 (DDR2 667 or DDR 800) memory. See
location of the memory module sockets.
You can upgrade the system memory by installing combinations of 512-MB,
1-GB, and 2-GB unbuffered memory modules. If you receive an error message
stating that maximum memory has been exceeded, see "System Messages" on
page 19 for more information. You can purchase memory upgrade kits from
Dell.
NOTE: The memory modules must be PC-5300/6400 compliant.
Memory Module Installation Guidelines
The memory module sockets are arranged in banks (1 and 2) on two channels
(A and B).
The memory module banks are identified as follows:
Bank 1: DIMM1_A and DIMM1_B
Bank 2: DIMM2_A and DIMM2_B
The memory module banks must be installed in identical pairs in
configurations that have more than one memory module. For example, if
socket DIMM1_A contains a 512-MB memory module, then the second
memory module to be installed must be a 512-MB memory module in socket
DIMM1_B.
Table 3-1 shows examples of different memory configurations, based on the
following guidelines:
•The minimum memory configuration is 512 MB.
•If only one memory module is installed, it must be installed in the
DIMM1_A socket.
•A bank must contain identical memory modules.
•Install the memory modules in bank 1 (DIMM1_
memory modules in bank 2 (DIMM2_

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 99.
Troubleshooting IRQ Assignment Conflicts
Most PCI devices can share an IRQ with another device, but they cannot use an
IRQ simultaneously. To avoid this type of conflict, see the documentation for
each PCI device for specific IRQ requirements. Table 4-2 lists the IRQ
assignments.

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 attached to
the external connectors on your system. See Figure 1-1 for the front-panel
connectors and Figure 1-2 for the back-panel connectors on your system.

Action
1
Check the system and power connections to the monitor.
2
Determine whether the system has monitors attached to both the front
and rear video connectors.
The system supports only one monitor attached to either the front or rear
video connector. When a monitor is connected to the front panel, and 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.
3
Check the system and power connections to the monitor.
4
Run the appropriate online diagnostic test. See "Using Dell PowerEdge
Diagnostics" on page 117.
If the tests run successfully, the problem is not related to video hardware.
If the tests fail, see "Getting Help" on page 127.
Troubleshooting the Keyboard
Problem
•System message indicates a problem with the keyboard.
•Keyboard is not functioning properly.
Action
1
Run the appropriate online diagnostic test. See "Using Dell PowerEdge
Diagnostics" on page 117.
