Safety Instructions
U
se the following safety guidelines to help protect
your computer system from potential damage and to
ensure your own personal safety.
3.
While you work, periodically touch an unpainted
metal surface on the computer chassis to dissipate
any static electricity that might harm internal
components.
When Working Inside the
Computer
WARNING: The power supplies in this computer
system produce high voltages and energy hazards,
which can cause bodily harm. Only trained service
technicians are authorized to remove the computer
covers and access any of the components inside the
computer.
WARNING: Before a trained service technician
accesses the inside of the computer, any and all
power supplies must be disconnected from their
power source, and the cables to the power supplies
must also be disconnected. If this computer has
more than one power supply, disconnect both
power supply cords before servicing to avoid
electrical shock.
Before taking the covers off of the computer, perform the
following steps in the sequence indicated:
1.
Turn off the computer and any peripherals.
2.
Disconnect the computer and peripherals from
their power sources. Also, disconnect any telephone or telecommunications lines from the
computer.
Doing so reduces the potential for personal injury or
shock.
Touch an unpainted metal surface on the computer chassis, such as the power supply, before
touching anything inside the computer.
In addition, take note of these safety guidelines when
appropriate:
•
To help avoid possible damage to the system board,
wait five seconds after turning off the system before
removing a component from the system board or disconnecting a peripheral device from the computer.
•
When you disconnect a cable, pull on its connector
or on its strain-relief loop, not on the cable itself.
Some cables have a connector with locking tabs; if
you are disconnecting this type of cable, press in on
the locking tabs before disconnecting the cable. As
you pull connectors apart, keep them evenly aligned
to avoid bending any connector pins. Also, before
you connect a cable, make sure both connectors are
correctly oriented and aligned.
•
Handle components and cards with care. Don’t touch
the components or contacts on a card. Hold a card by
its edges or by its metal mounting bracket. Hold a
component such as a microprocessor chip by its
edges, not by its pins.
Protecting Against Electrostatic
Discharge
Static electricity can harm delicate components inside the
computer. To prevent static damage, discharge static
electricity from your body before you touch any of the
computer’s electronic components, such as the
v
microprocessor. You can do so by touching an unpainted
metal surface on the computer chassis.
As you continue to work inside the computer, periodically touch an unpainted metal surface to remove any
static charge your body may have accumulated.
When Using the Computer
System
As you use the computer system, observe the following
safety guidelines:
In addition to the preceding precautions, you can also
take the following steps to prevent damage from electrostatic discharge (ESD):
•
Be sure the monitor and attached peripherals are
electrically rated to operate with the alternating current (AC) power available in your location.
•
When unpacking a static-sensitive component from
its shipping carton, do not remove the component’s
antistatic packing material until you are ready to
install the component in the computer. Just before
unwrapping the antistatic packaging, be sure to discharge static electricity from your body.
•
•
When transporting a sensitive component, first place
it in an antistatic container or packaging.
To help prevent electric shock, plug the computer
and peripheral power cables into properly grounded
power sources. These cables are equipped with
3-prong plugs to ensure proper grounding. Do not
use adapter plugs or remove the grounding prong
from a cable. If you must use an extension cable, use
a 3-wire cable with properly grounded plugs.
•
To help protect the computer system from sudden,
transient increases and decreases in electrical power,
use a surge suppressor, line conditioner, or uninterruptible power supply.
•
Be sure nothing rests on the computer system’s
cables and that the cables are not located where they
can be stepped on or tripped over.
•
Do not spill food or liquids on the computer. If the
computer gets wet, see Chapter 7, “Checking Inside
the Computer.”
•
Do not push any objects into the openings of the
computer. Doing so can cause fire or electric shock
by shorting out interior components.
•
Keep the computer away from radiators and heat
sources. Also, do not block cooling vents. Avoid
placing loose papers underneath the computer; do
not place the computer in a closed-in wall unit or on
a rug.
•
Handle all sensitive components in a static-safe area.
If possible, use antistatic floor pads and workbench
pads.
The following caution appears throughout this document
to remind you of these precautions:
CAUTION: See “Protecting Against Electrostatic
Discharge” in the safety instructions at the front of
this guide.

Table 2-1. Boot Routine Indications (continued)
Look/Listen for:
Action
An unfamiliar constant scraping or grinding sound
when you access a drive
Make sure the sound is not caused by the application program
you are running. The sound could be caused by a hardware malfunction. See Chapter 11, “Getting Help,” for instructions on
getting technical assistance from Dell.
The absence of a familiar sound
When you turn on the system, you should hear the hard-disk
drives spin up, and the system tries to access the boot files from
the hard-disk drive, the diskette drive, or CD-ROM drive. See
Chapter 5, “Running the System Diagnostics.” If the system
does not boot, see Chapter 11, “Getting Help.”
If after looking and listening to the computer you have
not resolved the problem, continue with the instructions
in “The System Setup Program” next in this chapter.
The System Setup Program
You can easily correct certain system problems by verifying the correct settings in the system setup program.
When you boot the system, the system checks the system
configuration information and compares it with the current hardware configuration. If the system hardware
configuration doesn’t match the information recorded by
the system setup program, an error message may appear
on the screen.
This problem can happen if you changed the system’s
hardware configuration and forgot to run the system
setup program. To correct this problem, enter the system
setup program, correct the corresponding system setup
category, and reboot the system. See Chapter 4, “Using
the System Setup Program,” in the system User’s Guide
for detailed instructions on using the system setup
program.
2-6
The System Configuration Utility
If you are experiencing problems with the system, you
may have a conflict between the information stored by
the system setup program and the system configuration
utility. Although the system configuration utility can read
changes from the system setup program, the change is not
recorded into nonvolatile random-access memory
(NVRAM) until you run the system configuration utility
and save the new information. See Chapter 5, “Using the
System Configuration Utility,” in the system User’s Guide
for detailed instructions on using the system configuration utility and saving new information.
If after using the system configuration utility you have
not resolved the problem, see Chapter 5, “Running the
System Diagnostics,” in this guide.

System Beep Codes
When errors occur during a boot routine that cannot be
reported on the monitor, the computer may emit a series
of beeps that identify the problem. The beep code is a pattern of beeps. For example, four beeps means the timer is
not operational. This information is valuable to the Dell
support staff if you need to call for technical assistance.
When a beep code is emitted, write it down on a copy of
the Diagnostics Checklist found in Appendix A, and then
look it up in Table 3-2. If you are unable to resolve the
problem by looking up the meaning of the beep code, use
the system diagnostics to identify a more serious cause. If
you are still unable to resolve the problem, see Chapter 11, “Getting Help,” for instructions on obtaining
technical assistance.

Warning Messages
A warning message alerts you to a possible problem and
asks you to do something before execution continues. For
example, before you format a diskette, a message may
warn you that you may lose all data on the diskette as a
way to protect against inadvertently erasing or writing
over the data. These warning messages usually interrupt
the procedure and require you to respond by typing a y
(yes) or n (no).
NOTE: Warning messages are generated by either the
application programs or the operating system. See
Chapter 4, “Finding Software Solutions,” and the documentation that accompanied the operating system and
application programs.

Dell PowerEdge 6100/200 System Installation and Troubleshooting Guide
Diagnostics Messages
When you run a test group or subtest in the system diagnostics, an error message may result. These particular
error messages are not covered in this chapter. Record the
message on a copy of the Diagnostics Checklist found in
Appendix A; then see Chapter 11, “Getting Help,” for
instructions on obtaining technical assistance.
Alert Log Messages From the
Dell HIP Program
The Dell HIP server management application program
generates alert messages that can be configured to appear
in the simple network management protocol (SNMP) trap
log file. To see the trap log, select any enterprise under
the SNMP trap log icon. More information about the
Alert Log window and options is provided in the Dell
HIP online help and the Dell HIP User’s Guide.
Alert log messages consist of information, status, warning, and failure messages for drive, temperature, fan, and
power conditions. They can assist you with identifying a
problem and may provide you with information to help
you resolve the problem. Alert log and other messages
are explained in the Dell HIP online help.
SCSI Hard-Disk Drive Indicator
Table 3-3 lists the drive indicator patterns established by
the SCSI backplane firmware. Different patterns are displayed as drive events occur in the system. For example,
in the event of a hard-disk drive failure, the “drive failed”
pattern appears. After the drive is selected for removal,
the “drive being prepared for removal” pattern appears,
followed by the “drive ready for insertion or removal”
pattern. After the replacement drive is installed, the
“drive being prepared for operation” pattern appears, and
then the “drive online” pattern appears.

ecause most computers have several application programs installed in addition to the operating system,
isolating a software problem can be confusing. Software
errors can also appear to be hardware malfunctions at
first. Software problems can result from the following
circumstances:
•
•
•
Improper installation or configuration of a program
•
Interrupt conflicts between devices
Input errors
Device drivers that may conflict with certain application programs
You can confirm that a computer problem is caused by
software by running the System Set Test Group as
described in Chapter 5, “Running the System Diagnostics.” If all tests in the test group complete successfully,
the error condition is most likely caused by software.
This chapter provides some general guidelines for analyzing software problems. For detailed troubleshooting
information on a particular program, see the documentation that accompanied the software or consult the support
service for the software.
Installing and Configuring
Software
You should check newly acquired programs and files for
viruses with virus-scanning software before installing the
programs on the computer’s hard-disk drive. Viruses,
which are pieces of code that can replicate themselves,
can quickly use all available system memory, damage
and/or destroy data stored on the hard-disk drive, and
permanently affect the performance of the programs they
infect. Several commercial virus-scanning programs are
available for purchase, and most bulletin board services
(BBSs) archive freely distributed virus-scanning programs that you can download with a modem.
Before installing a program, you should read any program documentation to learn how the program works,
what hardware it requires, and what its defaults are. A
program usually includes installation instructions in its
accompanying documentation and a software installation
routine on its program diskettes or CD(s).
The software installation routine assists users in transferring the appropriate program files to the computer’s
hard-disk drive. Installation instructions may provide
details about how to configure the operating system to
successfully run the program. You should always read
the installation instructions before running a program’s
installation routine.
When you run the installation routine, be prepared to
respond to prompts for information about how the computer’s operating system is configured, what type of
computer you have, and what peripherals are connected
to the computer.
Using Software
The following subsections discuss errors that can occur
as a result of software operation or configuration.
Error Messages
Error messages can be produced by an application program, the operating system, or the computer. Chapter 3,
“Messages and Codes,” discusses the error messages that
are generated by the system. If you receive an error message that is not listed in Chapter 3, check the operating
system or application program documentation.
Finding Software Solutions
4-1
Input Errors
If a specific key or set of keys is pressed at the wrong
time, a program may give you unexpected results. See the
documentation that came with the application program to
make sure that the values or characters you are entering
are valid.
Make sure that the operating environment is set up to
accommodate the programs you use. Keep in mind that
whenever you change the parameters of the computer’s
operating environment, you may affect the successful
operation of the programs. Sometimes, after modifying
the operating environment, you may need to
reinstall a program that no longer runs properly.
Program Conflicts
Some programs may leave portions of their setup information behind, even though you have exited from them.
As a result, other programs cannot run. Rebooting the
system can confirm whether these programs are the cause
of the problem.
There are also programs that use specialized subroutines
called device drivers that can also cause problems with the
computer system. For example, a variation in the way the
data is sent to the monitor may require a special screen
driver program that expects a certain kind of video mode or
monitor. In such cases, you may have to develop an alternative method of running that particular program—the
creation of a boot file made especially for that program, for
example. Call the support service for the software you are
using to help you with this problem.
Avoiding Interrupt Assignment
Conflicts
Problems can arise if two devices attempt to use the same
interrupt request (IRQ) line. To avoid this type of conflict, check the documentation for the default IRQ line
setting for each installed expansion card. Then consult
Table 4-1 to configure the card for one of the available
IRQ lines.

Running the System Diagnostics
U
nlike many diagnostic programs, Dell’s system diagnostics helps you check the computer’s hardware without
any additional equipment and without destroying any
data. By using the diagnostics, you can have confidence
in the computer system’s operation. And if you find a
problem you cannot solve by yourself, the diagnostic
tests can provide you with important information you
will need when talking to Dell’s service and support personnel.
CAUTION: Use the system diagnostics to test only
Dell computer systems. Using this program with
other computers may cause incorrect computer
responses or result in error messages.
•
Options to temporarily suspend testing if an error is
detected or to terminate testing when an adjustable
error limit is reached
•
A menu category called About that briefly describes
each test and its parameters
•
Status messages that inform you whether test groups
or subtests were completed successfully
•
Error messages that appear if any problems are
detected
When to Use the System
Diagnostics
Features of the System
Diagnostics
The system diagnostics provides a series of menus and
options from which you choose particular test groups or
subtests. You can also control the sequence in which the
tests are run. The diagnostic test groups or subtests also
have these helpful features:
•
Options that let you run tests individually or
collectively
•
An option that allows you to choose the number of
times a test group or subtest is repeated
•
The ability to display or print out test results or to
save them in a file
Whenever a major component or device in the computer
system does not function properly, you may have a component failure. As long as the microprocessor and the
input and output components of the computer system (the
monitor, keyboard, or CD-ROM drive) are working, you
can use the system diagnostics. If you know what component(s) you need to test, simply select the appropriate
diagnostic test group(s) or subtest(s). If you are unsure
about the scope of the problem, read the rest of this
chapter.
Running the System Diagnostics
5-1
Starting the System Diagnostics
The system diagnostics is run directly from the Dell Server
Assistant CD. See Chapter 2, “Using the Dell Server
Assistant CD” in the system User’s Guide for more information about the CD.
Follow these steps to run the diagnostics from the Dell
Server Assistant CD:
1.
Turn on the computer.
2.
Boot the system from the Dell Server Assistant
CD.
To boot from the CD, insert the CD into the
CD-ROM drive and press the reset button. If the system fails to boot, refer to the Dell Server Assistant
documentation.
3.
From the Dell Server Assistant main menu, select
the Run System Diagnostics option from the Run
System Utilities category.
NOTE: Before you read the rest of this chapter, you may
want to start the system diagnostics so you can see it on
the screen of the monitor.
When you start the diagnostics, the Dell logo screen
appears, followed by a message telling you that the diagnostics is loading. Before the diagnostics loads into
memory, a program tests the random-access memory
(RAM) that will be used by the diagnostics.
If no errors are found in RAM, the diagnostics loads, and
the Diagnostics Menu appears (see Figure 5-1). The
menu allows you to run all or specific diagnostic tests or
to exit to the Dell Server Assistant main menu.
For a quick check of the system, select the Run Quick
Tests option. This option runs only the subtests that do
not require user interaction and that do not take a long
time to run. Dell recommends that you choose this option
first to increase the odds of tracing the source of the problem quickly. For a complete check of the system, select
the Run All Tests option. To check a particular area of the
system, select the Run Specific Tests option.
To select an option from this menu, highlight the option
and press <Enter>, or press the key that corresponds to
the highlighted letter in the option you choose.

Confirming the System
Configuration Information
When you boot the system from the Dell Server Assistant
CD, the system diagnostics checks the system configuration information and displays it in the System
Configuration area on the main screen.
The following sources supply this configuration information for the system diagnostics:
•
The system configuration information settings
(stored in nonvolatile random-access memory
[NVRAM]) that you selected while using the system
setup program
•
Identification tests of the microprocessor, the video
controller, the keyboard controller, and other key
components
•
Basic input/output system (BIOS) configuration
information temporarily saved in RAM
Do not be concerned if the System Configuration area
does not list the names of all the components or devices
you know are part of the computer system. For example,
you may not see a printer listed, although you know one
is attached to the computer. Instead, the printer is listed as
a parallel port. The computer recognizes the parallel port
as LPT1, which is an address that tells the computer
where to send outgoing information and where to look
for incoming information. Because the printer is a parallel communications device, the computer recognizes the
printer by its LPT1 address and identifies it as a parallel
port.
How to Use the Menu
One of the menu categories is already highlighted. You
can move the highlight from one category to another by
pressing the left- or right-arrow key. As you move from
one menu category to another, a brief explanation of the
currently highlighted category appears on the bottom line
of the screen.
If you want more information about a test group or subtest, select the About category and press <Enter>. After
reading the information, press the <Esc> key to return to
the previous screen.
5-4
Main Menu Categories
Eight categories are listed in the menu area of the diagnostics main screen: Run, Select, Subtest, Options, Test
Limits, About, Key-Help, and Quit. (An additional
category, Display the Run Menu, returns you to the Diagnostics Menu described earlier in this chapter.)
NOTE: Before running any test groups or subtests (by
selecting Run), you should consider setting global parameters within the Options menu category. They offer you greater
control over how the test groups or subtests are run and how
their results are reported.
There are two ways to select a menu category:
•
Look on the screen to see which letter in the category
is capitalized, and type that letter (for example, type
r to select the Run category).
•
Move the highlight to the category you wish to select
by pressing the left- or right-arrow key, and then
press <Enter>.
Whenever one of the eight categories is selected, additional choices become available.
The following subsections explain the menu categories as
listed from left to right in the main screen.

Options
Table 5-1 lists all of the possible values for each global
parameter of the Options menu category from the main
screen. A brief description of each parameter follows. To
change Options parameters, press the <Spacebar>, the
left- and right-arrow keys, or the plus (+) and minus (–)
keys.
Number of Times to Repeat Test(s)
This parameter specifies the number of times the tests run
when you select Run. To change the default, type in the
desired value. If you type 0 (zero), the tests will run
indefinitely.
Maximum Errors Allowed
This parameter specifies the maximum number of errors
that can occur before testing is stopped. The error count
begins from zero each time you run a subtest or test
group individually or each time you select All to run all
of them. To change the default, type in the desired value.
If you type 0 (zero), you are specifying that there be no
limit on the number of errors that can occur—testing will
not be stopped, regardless of the number of errors.
Pause for User Response
If this parameter value is set to Yes, the diagnostics
pauses when one of the following occurs:
•
Your interaction is needed to verify the Video Test
Group screens or the Keyboard Test Group key functions or other types of interaction such as inserting a
diskette.
•
The maximum error limit is reached.
If the Pause for User Response parameter is set to No, the
diagnostics ignores some subtests that require your interaction; certain subtests can run only if this option is set to
Yes because they require user interaction. Use this
parameter in situations where you may want to prevent
subtests that require user interaction from running—such
as when you run the diagnostics overnight.

Output Device for Status Messages
Display, Printer, File
If you have a printer attached to the computer, you can use it to print
the status messages, if any, that are generated when a test runs. (The
printer must be turned on and in the online mode to print.) If you select
File, the messages are printed to a file named result in diskette drive
A. The default is Display.
Output Device for Error Messages
Display, Printer, File
This parameter has the same effect as the Output Device for Status
Messages parameter, except that it pertains only to error messages.
The default is Display.
5-6
Dell PowerEdge 6100/200 System Installation and Troubleshooting Guide
Output Device for Status Messages
Ordinarily, all status messages appear only on the screen.
This parameter allows you to direct status messages to
either a printer or a file, in addition to the screen. If you
choose the File option, status messages are written to a
file named result. This file is automatically created on a
diskette in drive A when you run the diagnostics. If the
result file already exists on the diskette, then new status
messages are added to it.
The result file is an ordinary American Standard Code
for Information Interchange (ASCII) text file. You can
access the result file with the MS-DOS® type command
as follows:
1.
Select Quit to exit the diagnostics and return to
the operating system prompt.
2.
At the operating system prompt, type the following command line and press <Enter>:
type result
The contents of the file appear on the screen.
After running particular diagnostic tests and viewing the
status messages generated by the tests in the result file,
you can erase the contents of the file so that it is clear for
the next set of messages generated. Otherwise, the next
messages are added at the end of the previous ones in the
file.
Output Device for Error Messages
Ordinarily, all error messages appear only on the screen.
This parameter allows you to direct error messages to
either a printer or a file, in addition to the screen. If you
choose the File option, error messages are written to the
result file used for status messages. This file is automatically created on a diskette in drive A when you run the
diagnostics. If the result file already exists on the diskette, then new error messages are added to it.
The result file is an ordinary ASCII text file. You can
access and review the result file with the MS-DOS type
command as described in the previous subsection, “Output Device for Status Messages.”
After running particular diagnostic tests and viewing the
error messages generated by the tests in the result file,
you can erase the contents of the file so that it is clear for
the next set of messages generated. Otherwise, the next
messages are added at the end of the previous ones in the
file.
Test Limits
NOTE: The diagnostics program sets default limits on all
tests. The only reason to change the default would be to
limit the amount of testing done.
The RAM Test Group, the Video Test Group, the Diskette
Drives Test Group, the Serial/Infrared Ports Test Group,
the Parallel Ports Test Group, and the SCSI Devices Test
Group allow you to designate limits. Whether you select
Test Limits for a highlighted test group (from the main
screen) or a subtest (from the Subtest menu), you set the
limits for all the subtests in that test group. When you
select Test Limits, a new screen appears and the Key
Help area lists keys to use with the new screen.
How you change a value for the limits of a test group or
subtest depends on the type of parameter associated with
it. Different keys are used to change values for different
types of parameters. For example, memory address limits
specified for the RAM Test Group are changed by typing
in numbers over the digits of a given limit or by pressing
the plus (+) or minus (–) keys to increase or decrease the
given limit. In contrast, to set limits for the Serial/Infrared
Ports Test Group, you use the <Spacebar> to toggle
between Yes and No.
After you are satisfied with the limits, return to the main
screen of the diagnostics by pressing the <Esc> key. The
values you selected under Test Limits remain in effect
during all the test groups or subtests you run, unless you
change them. However, the values are reset to their
defaults when you restart the diagnostics.
About
About in the main screen lists all of the subtests for the
selected test group and displays information about the
subtest that is highlighted.
Key-Help
Key-Help in the main screen always displays a list of key
controls available for the particular category you have
selected.
Running the System Diagnostics

Quit
Selecting Quit from the main screen exits the diagnostics
and returns you to your operating system environment.
CAUTION: It is important that you quit the diagnostics program correctly because the program
writes data to the computer’s memory that can
cause problems unless properly cleared.
Tests in the System Diagnostics
To troubleshoot components or devices, run the appropriate test (test group or subtest) in the diagnostics. The
diagnostics exercises the functional components and
devices of the computer system more vigorously and
thoroughly than they are exercised during normal operation. The diagnostics is organized by components into
test groups and subtests within each test group. Each subtest is designed to detect any errors that may interfere
with the normal operation of a specific device of the
computer.
NOTE: Some subtests requiring hardware not listed in
the System Configuration area of the diagnostics screen
appear to run, but they conclude with a status message
stating Component not present (or disabled).
Table 5-2 lists the diagnostic test groups, their subtests,
and comments concerning their use.

Error Messages
When you run a test group or subtest in the diagnostics,
error messages may result. These particular error messages are not covered in this chapter because the errors
that generate these messages can be resolved only with
Dell technical assistance. Record the messages on a copy
of the Diagnostics Checklist found in Appendix A, and
see Chapter 11, “Getting Help,” for instructions on
obtaining technical assistance and informing the support
technician of these messages.
•
Confirms the functionality of the computer’s cache
memory.
Why Run a RAM Test?
Faulty memory can cause a variety of problems that may
not, at first glance, appear to be happening in RAM. If the
computer is displaying one or more of the following
symptoms, run the subtests in the RAM Test Group to
verify that the memory is not at fault:
•
A program is not running as usual, or a proven piece
of software appears to malfunction and you
confirm that the software itself is not at fault. You
can confirm that the software is functioning properly
by moving it to another computer and running it
there.
•
The computer periodically locks up (becomes unusable and must be rebooted), especially at different
places and times in different programs.
•
You get parity errors (any error message that contains the word parity) at any time during operation.
These errors are usually accompanied by a reference
to an address—the location of the portion of memory
where the error occurred—which you should record
on a copy of the Diagnostics Checklist found in
Appendix A.
•
You receive the Memory ECC fault
detected message from the Dell Hardware Instrumentation Package (HIP) server management
program. See “Alert Log Messages From the Dell
HIP Program” in Chapter 3, “Messages and Codes,”
for more information on this message. See the Dell
HIP User’s Guide for information on the program.
RAM Test Group
The RAM Test Group subtests check all the directly
addressable RAM.
Subtests
The following subtests are available for RAM:
•
Quick Memory Test
The Quick Memory Test performs an address check
to determine whether the computer is properly setting and clearing individual bits in RAM and
whether the RAM read and write operations are
affecting more than one memory address location at
one time. This subtest checks all available RAM.
•
Comprehensive Memory Test
The Comprehensive Memory Test performs an
address check, as well as the following:
— Data pattern checks, to look for RAM bits that
are stuck high or low, short-circuited data lines,
and some data pattern problems that are internal
to the memory chips
•
Cache RAM Test
— A parity check that verifies the ability of the
memory subsystem to detect errors
System Set Test Group
— A refresh check, to verify that the dynamic
RAM (DRAM) is being recharged properly
The subtests in the System Set Test Group check the
computer’s basic system board components and verify
their related functions.
Cache Controller Test
Confirms the functionality of the computer’s cache
controller chip.

•
CMOS Confidence Test
Checks the NVRAM for accessibility and reliability
of data storage by performing a data pattern check
and verifying the uniqueness of memory addresses.
•
•
DMA Controller Test
Tests the direct memory access (DMA) controller
and verifies the correct operation of its page and
channel registers by writing patterns to the registers.
•
Real-Time Clock Test
Confirms the functionality and accuracy of the computer’s real-time clock (RTC).
•
Timers Test
Checks the timers used by the microprocessor for
event counting, frequency generation, and other
functions. Only the functions that can be activated
by software are tested.
•
•
Why Run a System Set Test?
The System Set subtests double-check many system
board components, such as the computer’s input/output
(I/O) circuitry, that are tested by other test groups or
subtests in the diagnostics. You should run the System
Set Test Group if you are having a problem and cannot
isolate the failure or malfunction to a particular system
board component.
The System Set Test Group also verifies the proper operation of other computer components, such as the speaker,
that are not tested elsewhere in the diagnostics.
The following symptoms usually suggest a problem with
a component or subassembly that warrants running a System Set subtest:
•
A program is not running as usual, or a proven piece
of software appears to malfunction and you confirm
that the software itself is not at fault. You can confirm that the software is functioning properly by
moving it to another computer and running it there.
•
An option card you previously accessed can no
longer be accessed.
•
You get parity errors or page fault failures (any error
message that contains the words parity or page fault)
at any time during operation. These errors are usually accompanied by a reference to an address,
which you should record on a copy of the Diagnostics Checklist found in Appendix A.
•
Correcting errors in the system configuration information in the system setup program or the system
configuration utility does not resolve a problem.
•
The computer’s clock/calendar stops.
Speaker Test
x87 Calculation Test
Apic Test and Apic MP Test
For systems with multiprocessors, confirms that the
additional microprocessors are operational.
Checks the functionality of the speaker by generating eight tones.
•
x87 Error Exception Test
Verifies the math coprocessor’s ability to handle
errors and to send IRQs to the microprocessor.
Interrupt Controller Test
Generates an interrupt on each interrupt request
(IRQ) line to verify that devices using that line can
communicate with the microprocessor(s) and that the
interrupt controllers send the correct memory
addresses to the microprocessor(s).
•
•
EISA Configuration Memory Test
Verifies the accessibility and reliability of the RAM
on the Extended Industry-Standard Architecture
(EISA) configuration RAM chip, which stores the
EISA hardware configuration information. On systems without flash RAM, performs a data pattern
and address uniqueness test.
x87 Duty Cycle Test
Checks the use of different types of numbers and the
math coprocessor’s ability to calculate correctly.

•
The speaker no longer functions. The problem could
be a failure of the system timers as well as a failure
of the speaker itself. Run the Timers Test, followed
by the Speaker Test.
If a peripheral device appears to malfunction, run the
Interrupt Controller Test.
A spreadsheet program or other type of mathematical application runs abnormally slow, generates
error messages concerning calculations or operations, runs incorrectly, or generates incorrect results,
or a proven piece of the program appears to malfunction and you confirm that the software itself is
not at fault. You can confirm that the software is not
at fault by moving the program to another computer
and running it there.
•
The computer periodically locks up, especially at
different places and times in different programs.
•
The computer halts in the middle of performing calculations or complex mathematical operations.
Video Test Group
The subtests in the Video Test Group verify the proper
operation of the video controller and the video control
circuitry installed in the computer. These subtests check
for the correct operation of the readable registers in the
video circuitry and the controller. They write, read, and
verify data patterns in the cursor registers of the controller. The Video Test Group also tests all the video memory
and provides additional subtests to test the color features
of a color monitor.
NOTE: Most of the subtests are interactive; that is, you
must respond before the diagnostics continue to the next
subtest.
Subtests
The subtests in the Video Test Group and the video functions they confirm follow:
•
Video Memory Test
Checks the read/write capability of video memory in
various video modes.
5-12
•
Video Hardware Test
Checks the cursor registers and the horizontal and
vertical retrace bit registers in the video controller.
•
Text Mode Character Test
Checks the video subsystem’s ability to present data
in text modes.
•
Text Mode Color Test
Checks the video subsystem’s ability to present color
in text modes.
•
Text Mode Pages Test
Checks the video subsystem’s ability to map and
present all available video pages on the screen, one
page at a time.
•
Graphics Mode Test
Checks the video subsystem’s ability to present data
and color in graphics modes.
•
Color Palettes Test
Checks the video subsystem’s ability to display all of
the available colors.
•
Solid Colors Test
Checks the video subsystem’s ability to show
screens full of solid colors. Allows you to check for
missing color subpixels.
Many of these tests display characters or graphics on the
screen for you to verify. Samples of these screens are
shown in Appendix B, “Diagnostic Video Tests.”
NOTE: The default limit for testing super video graphics
array (SVGA) modes is No. If you are testing an external
monitor, change the default to Yes.
Why Run a Video Test?
Many of the symptoms that would prompt you to run a
subtest in the Video Test Group are obvious, because the
monitor is the visual component of the computer system.
Before you run the Video Test Group or any of its subtests, you should make sure that the problem is not in the
software or caused by a hardware change. You should
also try running all of the software support utilities provided for the monitor and the video subsystem.
Dell PowerEdge 6100/200 System Installation and Troubleshooting Guide
If the following symptoms still occur, run the appropriate
test(s) as follows:
•
If the monitor shows a partially formed or distorted
image, run all of the subtests in the Video Test
Group.
•
If the alignment of text or images is off, regardless of
the program you are running, run the Text Mode
Character Test, Text Mode Pages Test, and Graphics
Mode Test.
•
If you have a color monitor or a program that runs in
color, but the color is intermittent or not displayed at
all, run the Text Mode Color Test, Color Palettes
Test, and Solid Color Test.
•
If the monitor malfunctions in one mode but works
fine in another (for example, text is displayed correctly, but graphics are not), run the Text Mode
Character Test, Text Mode Color Test, Text Mode
Pages Test, and Graphics Mode Test.
Keyboard Test Group
The subtests in the Keyboard Test Group verify the correct operation of the keyboard and the keyboard
controller chip.
•
Checks the internal microcode of the keyboard and
the external interface of the keyboard controller chip
for a repeating-key signal.
Why Run a Keyboard Test?
Keyboard problems are not always caused by the
keyboard. For example, a complete lockup of the computer system, rendering the keyboard inoperable, is more
likely caused elsewhere. There are three symptoms that
are likely to be keyboard-related. Sometimes, the configuration of a program changes the function of a key or key
combination. Likewise, key configuration programs can
change a key’s function. Because these programs are
memory resident, you should be sure to clear them out of
the computer’s memory before running a subtest in the
Keyboard Test Group. Clear them from memory by
rebooting the computer from the Dell Server Assistant
CD. When these possibilities have been eliminated, and
if the following symptoms occur, you should run one or
more of the subtests in the Keyboard Test Group:
•
When you press a key, the character represented by
that key appears repeatedly; the key seems to be
stuck. Run the Stuck Key Test.
•
When you press a key and the response is different
from the usual response or the response you anticipated, the key contact may be damaged. Run the
Keyboard Interactive Test.
•
When a key does not work at all, run all of the subtests in the Keyboard Test Group.
Subtests
The keyboard subtests and the keyboard functions they
confirm follow:
•
•
Controller Test
Confirms the ability of the keyboard controller chip
to communicate with the keyboard and the programming of the controller chip.
Mouse Test
Key Sequence Test
The Mouse Test checks the functionality of the mouse
controller (which coordinates cursor movement on the
screen with corresponding movement of the mouse or
touch pad) and the operation of the mouse keys/touch
pad.
Verifies that the keys on the keyboard function correctly when you press the keys in a predefined order.
•
Stuck Key Test
Interactive Test
Checks the internal microcode of the keyboard and
the external interface of the keyboard controller chip
for a malfunctioning key.
Subtests
There are no subtests for the Mouse Test Group.
Running the System Diagnostics
5-13
Why Run the Mouse Test?
Mouse or touch pad problems are as likely to originate in
RAM as they are to be caused by a faulty mouse or touch
pad. Three sources of RAM-related problems include the
configuration of a program (which changes the function
of the mouse or touch pad), memory-resident programs,
and failure of a device driver (the software that controls
the function of the mouse or touch pad). If these possibilities have been eliminated and the following symptoms
persist, run the Mouse Test:
•
When you press a mouse button or the touch pad, the
function of the button (or touch pad) continues; that
is, the button (or touch pad) seems to be stuck.
•
If the response when you press a mouse button or the
touch pad is different from the usual or anticipated
response, the button (or touch pad) contact may be
damaged.
•
A mouse button or the touch pad does not work at
all.
•
The cursor does not respond on the screen in accordance with the movements you make with the mouse
or touch pad.
Diskette Drives Test Group
The subtests in the Diskette Drives Test Group allow you
to test both 5.25-inch and 3.5-inch diskette drives of all
capacities.
Subtests
The diskette drive subtests in the Diskette Drives Test
Group and the drive functions they confirm follow:
•
Change Line Test
Checks for bent pins on the diskette drive controller
and for defective lines on the diskette cable.
•
Seek Test
Checks the drive’s ability to search for a specified
track on the diskette and to position its read/write
heads to all tracks.
•
Read Test
Positions the read/write heads at each cylinder of the
diskette for reading data and verifies that all tracks
on the diskette can be read correctly.
•
Write Test
Positions the read/write heads at each cylinder of the
diskette and verifies that all tracks on the diskette
can be written to correctly.
Why Run a Diskette Drives Test?
Often, a diskette drive problem may first appear to be a
diskette problem. A box of defective diskettes might produce faulty-drive error messages. The test results can be
confusing, so Dell suggests running the subtests in the
Diskette Drives Test Group more than once using diskettes from different sources.
Another possible cause of diskette drive problems is
human error—typing a command in an incorrect form
(usually called a syntax error). Be sure you have entered
the command in the proper form.
When the diskette(s) and command syntax are eliminated
as causes, the following symptoms usually suggest a
drive problem and warrant running a subtest in the Diskette Drives Test Group:
•
An error message appears on the screen stating that
the computer cannot read from or write to a diskette.
•
A diskette cannot be properly formatted, or format
error messages appear on the screen.
•
Data on diskettes is corrupted or lost; these problems
may be intermittent.
Serial/Infrared Ports Test Group
The subtests in the Serial/Infrared Ports Test Group
check the computer’s interface with external devices,
such as a printer and a mouse, that are connected to the
computer through a serial or infrared port. The subtests in
this test group are not intended as a diagnostic test for the
actual peripheral attached to each port.
NOTES: With certain modems installed, the subtests in
the Serial/Infrared Ports Test Group may fail because the
modem appears to the diagnostics as a serial or infrared
5-14
Dell PowerEdge 6100/200 System Installation and Troubleshooting Guide
port, but it cannot be tested as a serial or infrared port. If
a modem is installed and one of the subtests in the Serial/
Infrared Ports Test Group fails, remove the modem and
run the diagnostic tests again.
If an external loopback connector is not attached to a
serial or infrared port, the External Transmission Test
will fail for that port and the results of this test should
therefore be ignored. An external modem connected to
the port does not substitute for an external loopback
connector.

operating system. If it still does not work, you can eliminate the software configuration as the cause of the
problem.
Another possible cause for errors is the external device.
Use the documentation that came with the peripheral to
troubleshoot it and confirm that it is working properly.
Most printers have a self-test.
After you eliminate incorrect system configuration
information settings, peripheral malfunctions, and software errors as potential causes of port problems, you can
run the subtests in the Serial/Infrared Ports Test Group to
check the hardware. Although the following symptoms
can be caused by faulty peripherals or software errors,
they might also suggest a port problem:
Baud Rate Test
•
If a peripheral works intermittently or produces
intermittent errors, the port may be faulty.
Checks the baud rate generator in each serial communications chip against the computer’s clock.
•
If the computer displays an error message that is
related to the external device connected to a port, but
corrections to the device do not resolve the error, run
the appropriate subtest in the Serial/Infrared Ports
Test Group.
•
If the software and the diagnostics do not recognize
that you have a serial or infrared port, you should
check the Serial Port 1 Address and Serial Port 2
Address categories in the system setup program, and
if necessary, run the appropriate subtest in the Serial/
Infrared Ports Test Group.
Interrupt Test
Checks the serial port’s ability to send IRQs to the
microprocessor.
•
Internal Transmit Test
Checks several internal functions of the serial port
using the internal loopback mode of the serial communications chip.
•
External Transmit Test
If a loopback device is attached, checks the line control bits of the serial port and sends a test pattern at
several baud rates, checking the returned values.
Why Run a Serial/Infrared Ports Test?
If the diagnostics does not recognize the computer’s
serial or infrared ports, enter the system setup program
and check the Serial Port 1 Address and Serial Port 2
Address categories to see whether the port has been disabled. The subtests in the Serial/Infrared Ports Test
Group cannot test a port unless it is enabled.
When a port is faulty, it may not be immediately evident
that the port, and not the device connected to the port, is
faulty. Instead, the peripheral (such as a printer or mouse)
might behave erratically or not operate at all. If the external device is not properly installed through the
software, it also may not function properly. Try operating
the peripheral from different programs or through the
Parallel Ports Test Group
The subtests in the Parallel Ports Test Group check the
computer’s interface with external devices, such as a
printer, that are connected to the computer through a parallel port. The subtests in the Parallel Port Test Group are
not intended as a diagnostic test for the actual peripheral
attached to each port. The only exception is a printer, as
described in the Internal Test.
NOTE: If an external loopback connector is not attached
to the parallel port, the External Loopback Test will fail
for that port and the results of this test should therefore
be ignored.

•
If the software and the diagnostics do not recognize
that you have a parallel port, you should check the
Parallel Port ECP-DMA category in the system setup
program, and if necessary, run the appropriate subtest in the Parallel Ports Test Group.
External Loopback Test

external loopback connector, if an external loopback
connector is available.
•
caused by faulty peripherals or software errors, they
might also suggest a port problem:
External Interrupt Test
Tests the parallel port’s ability to generate interrupts
from all possible sources, if an external loopback
connector or printer is available.
•
Printer Pattern Test
Tests a printer and tests the parallel port’s ability to
send a pattern to the printer, if connected.
Why Run a Parallel Ports Test?
If the diagnostics does not recognize the computer’s parallel port, enter the system setup program and check the
Parallel Port ECP-DMA category to see if the port has
been disabled. The subtests in the Parallel Ports Test
Group cannot test a port unless it is enabled.
SCSI Devices Test Group
The subtests in the SCSI Devices Test Group check the
functionality of up to four small computer system interface (SCSI) host adapters and all the SCSI devices
attached to them.
NOTES: Before conducting these subtests on CD-ROM
drives, insert a CD with audio and data tracks (such as a
multimedia CD) into each CD-ROM drive. All of the subtests require a CD with data tracks.
When a port is faulty, it may not be immediately evident
that the port, and not the device connected to the port, is
faulty. Instead, the peripheral (such as a printer) might
behave erratically or not operate at all. If the external
device is not properly installed through the software, it
also may not function properly. Try operating the peripheral from different programs or through the operating
system. If it still does not work, you can eliminate the
software setup as the cause of the problem.
If a CD-ROM drive is empty or if it contains a CD that
does not have the required data or audio tracks (depending on the subtest[s] being conducted), the subtest(s) will
fail.
Another possible cause for errors is the external device.
Use the documentation that came with the peripheral to
troubleshoot it and confirm that it is working properly.
Most printers have a self-test.

Positions the read/write heads at each block of the
device for reading data and verifies that all tracks on
the device can be read correctly.
•
•
The following are the most common symptoms that
might prompt you to test a SCSI device:
•
•
A SCSI hard-disk drive fails during the boot routine.
Positions the read/write heads at each block of the
device and verifies that all tracks on the device can
be written to correctly.
•
An error message appears on the screen stating that
the computer cannot read from or write to a SCSI
device.
Eject Test
•
Data on a SCSI device is corrupted or lost; this problem may be intermittent. Once saved by a program,
files cannot be properly recalled.
Write Test
Causes a CD-ROM drive to eject its CD or a SCSI
tape drive to eject its tape cartridge.
Seek errors are reported by the operating system or
application programs.
Why Run a SCSI Devices Test?
If you check the SCSI hard-disk drive to determine the
amount of available space, the operating system will probably report problem areas. Problem areas on hard-disk
drives are common because most hard-disk drives have a
small amount of space that is not usable. The hard-disk
drive keeps a record of this space so that the computer will
not attempt to use it. Identification of unusable disk space,
unless it is an unusually large amount (over five percent of
the possible total), should not be regarded as a cause for
testing the hard-disk drive.

When you look inside the computer, note the direct current
(DC) power cables leading from the power-supply paralleling board. These cables supply power to the system
board, small computer system interface (SCSI) backplane
board, externally accessible drives, and certain expansion
cards that connect to external peripherals.
The flat ribbon cables are the interface cables for internal
drives. For SCSI devices, the interface cable connects
externally accessible SCSI devices and the SCSI backplane board to a SCSI host adapter either on the system
board or on an expansion card.
The system board—the large, vertical printed circuit board
at the left side of the chassis near the back—holds the
computer’s control circuitry and other electronic components. Some hardware options are installed directly onto
the system board. The system board provides 10 expansion-card connectors. The external drive bays provide space
for up to four half-height drives, typically diskette drives,
CD-ROM drives, or tape drives. The internal drive bays
provide space for up to six half-height SCSI hard-disk
drives. These drives are connected to the SCSI host
adapter via the SCSI backplane board, which manages the
drive bays and monitors the drive environment, including
voltages and temperatures.
During an installation or troubleshooting procedure, you
may be required to change a jumper or switch setting on the
system board, the microprocessor module, an expansion
card, or a drive. For more information on the jumpers and
switches, see Appendix C, “Jumpers, Switches, and
Connectors.”

Adding Memory
The 16 single in-line memory module (SIMM) sockets on
the memory module can accommodate 64 to 2048 megabytes (MB) of dynamic random-access memory (DRAM).
The Dell PowerEdge 6100 systems use 72-pin, 36-bit buffered SIMMs in these 72-pin sockets. The memory module
The system is upgradable to 2048 MB (2 gigabytes [GB])
by installing combinations of 16- or 64-MB single-sided or
32-MB or 128-MB double-sided SIMMs. The SIMMs
should be rated at 60 nanoseconds (ns) or 70 ns. Table 8-1
shows several sample memory configurations. Memory
upgrade kits can be purchased from Dell as needed.
SIMM Installation Guidelines
The SIMM sockets are labeled “J1” through “J16” (see
Figure 8-4). Slots J1 to J8 make up bank 1; slots J9 to J16
compose bank 2.

•
When installing SIMMs, follow these guidelines:
•
Install the SIMM with the pin 1 end aligned with the
pin 1 end of the socket (see Figure 8-5).
•
Install a SIMM in socket J1 before socket J2, socket
J2 before socket J3, and so on.
•
All SIMMs in one bank must be the same size and
speed, but SIMMs in bank 1 may differ in size from
those in bank 2.
SIMMs must be installed in groups of four, eight, or
16 only.
The following SIMM interleaving is supported:
•
•
•
Two-way interleaved using J1 to J4
Four-way interleaved, single bank using J1 to J8
Four-way interleaved, dual bank using J1 to J16

Use the following procedure to perform a memory
upgrade:
1.
Remove the left computer cover.
See “Removing the Computer Covers” in Chapter 7.
CAUTION: See “Protecting Against Electrostatic Discharge” in the safety instructions at
the front of this guide.
2.
Figure 8-4 shows the location of the SIMM sockets
on the memory module.

7.
Replace the memory module.
Remove the memory module.
Hold the module by the corners with the SIMM
sockets facing down. Ease the module into the correct slot guides until it is touching the system board
connector. Press the module carefully but firmly into
the system board connector and rotate the handles
closed.
Hold the module by the corners where the handles
are and carefully pull the module out until the edge
connectors are free from the system board connector.
NOTE: Before closing the handles, make sure the
memory module is aligned with the system board
connector.
Remove the support panel.
NOTE: Be careful not to touch components or gold
edge connectors on the module.
4.
Install or replace the SIMMs as necessary to
reach the desired memory total.
Follow the instructions in “Installing SIMMs” or
“Removing SIMMs” later in this section, as
appropriate.
Remove the two screws from the support panel (see
Figure 7-4) and pull the back edge tabs on the panel
out of the slots in the chassis.
3.
Locate the SIMM sockets into which you will
install or replace SIMMs.
Place the memory module component-side up
onto an antistatic surface.
8.
Replace the support panel.
Align the panel so that the two tabs are to the left. Fit
the tabs into the two slots on the chassis back and
swing the panel closed. Replace the two screws
removed in step 2.
Installing System Board Options
8-7
9.
Replace the left computer cover, reconnect the
computer and peripherals to their power sources,
and turn them on.
CAUTION: Make sure the memory module is
completely seated in the system board connector before applying power. Incomplete
insertion can damage to the system board and
memory module.
After the system completes the power-on self-test
(POST) routine, it runs a memory test that displays
the new memory total, which includes all newly
installed memory.
NOTE: If the memory total is incorrect, turn off and
disconnect the computer and peripherals from their
power sources, remove the computer cover and
memory module, and check all the installed SIMMs
to make sure they are seated properly in their sockets. Then repeat steps 7 through 9.
The system detects that the new memory does not
match the system configuration information, which
is stored in nonvolatile random-access memory
(NVRAM). The monitor displays an error message
to that effect, ending with the following words:
11. Enter the system configuration utility. Then save
the configuration and exit the utility.
Running the system configuration utility and saving
the configuration is required for the system to recognize the newly installed SIMMs. See Chapter 5,
“Using the System Configuration Utility,” in the
User’s Guide for instructions on running the utility
and saving the configuration.
12. Run the RAM Test Group in the system
diagnostics.
See Chapter 5, “Running the System Diagnostics,”
for information.
Installing SIMMs
The memory module has 16 SIMM sockets arranged in
two banks. Install SIMMs starting with the bottom
socket, J1, and work toward J16. All SIMMs in one bank
must be the same size and speed, but SIMMs in bank 1
may differ in size from those in bank 2. If a SIMM is
already installed in the socket you need, you must
remove it. Follow the instructions in the next subsection,
“Removing SIMMs,” if appropriate.
To install a SIMM, follow these steps:
1.
Remove the memory module as described in steps 1
to 5 of “Performing a Memory Upgrade” earlier in
this section and place the module with the system
board connector pointed away from you.
2.
Align the SIMM so that the notch is in the lower
left corner.
Press <F1> to enter System Setup.
10. Press <F1> to enter the system setup program, and
check the Extended Memory category in the Main
menu of the system setup screens.
See Chapter 4, “Using the System Setup Program,”
in the system User’s Guide for more information.
The system should have already changed the value in
the Extended Memory category to reflect the newly
installed memory. Verify the new total.
NOTE: The value of Extended Memory is given in
kilobytes. To convert kilobytes to megabytes, divide the
kilobyte total by 1024.
If the total is incorrect, one or more of the SIMMs
may not be installed properly. Repeat this procedure
again, checking to make sure the SIMMs are firmly
seated in their sockets.
8-8
The pin-1 end of the SIMM must align with the pin-1
end of the socket (see Figure 8-5).
3.
Hold the SIMM at a 45-degree angle with the top
angled away from you and carefully press the
SIMM into the socket until the SIMM is held by
the clips (see Figure 8-5).
When properly inserted, the SIMM remains at an
angle. If there is a gap between the clips and the
SIMM, it is not installed properly and you must
repeat step 3.

Removing SIMMs
To remove a SIMM, start from the highest-numbered
socket, open the retaining clips just enough to lift the top
edge of the SIMM away from the clips, and lift the
SIMM out of the socket (see Figure 8-6).
Upgrading the Microprocessor or
Installing Additional
Microprocessors
The system board has two microprocessor module connectors. Each microprocessor module can have one or
two Intel® Pentium® Pro microprocessors installed for a
total of four microprocessors (see Figure 8-7). All microprocessors on both modules must be identical. For
example, if the system has a 200 megahertz (MHz)
Pentium Pro microprocessor and you are adding microprocessors, all additional microprocessors must also be
200 MHz Pentium Pro.
Figure 8-7. Microprocessor Module
Installing System Board Options
8-9
Both microprocessor module sockets must be filled
regardless of how many microprocessors are installed;
you must use a bus termination module in the second
socket if you have only one microprocessor installed.
Note that both sockets on the primary module should be
populated before populating the sockets on the secondary
module. Table 8-2 shows the valid microprocessor
configurations.
Similarly, both of the microprocessor module connectors
on the system board must be populated. For example, if
you are using only one or two microprocessors on one
microprocessor module (thus populating the primary
connector), the second connector on the system board
must also be populated with either another microprocessor module or a terminator card.

NOTE: If you decide to upgrade your system by installing
additional microprocessors (up to four microprocessors
total), you must order a microprocessor upgrade kit from
Dell. Not all versions of the Pentium Pro microprocessor
will work properly as an additional microprocessor. The
upgrade kit from Dell contains the correct revision of the
microprocessor chip for use as a additional microprocessor, as well as instructions for performing the
upgrade. (A trained service technician must perform the
upgrade.) All additional microprocessors must have the
same internal operating frequency as the first.

The RTC chip has a built-in lithium battery that maintains system configuration, date, and time information in
a special section of memory when the system is turned
off.
The built-in battery can power the RTC chip for up to
10 years without a power source; the actual operating life
of the battery depends on how the system is used (for
example, if the system is on most of the time, the battery
gets little use and thus lasts longer).
To determine if the RTC chip needs replacing, reenter the
time and date through the system setup program. Turn off
the system for a few hours, and then turn it on again.
Enter the system setup program. If the date and time are
not correct in the system setup program, replace the RTC
chip.
NOTES: Some software may cause the system time to
speed up or slow down. If the system seems to operate
normally except for the time kept in the system setup program, the problem may be caused by software rather than
by a defective RTC chip.
The system can be operated without a RTC chip; however, the system configuration information maintained by
Dell PowerEdge 6100/200 System Installation and Troubleshooting Guide
the RTC chip in NVRAM is erased each time the computer is turned off. Therefore, the system configuration
information must be reentered and the options reset each
time the system boots until the RTC chip is replaced.

With the pin-1 corners of the socket and chip
aligned, set the chip lightly in the socket and make
sure all pins are matched with the correct holes in the
socket. When the chip is positioned correctly, press
down until the chip is firmly in the socket.
CAUTION: When placing the RTC chip in the
socket, be sure that all of the pins on the chip
go into the corresponding holes of the socket.
Be careful not to bend the pins.
NOTE: The cable tie binding the chip to the system
board was necessary for shipping purposes. You will
not need to replace the tie after replacing the RTC
chip.

Installing Drives in the External Bays
T
he external drive bays at the front of the Dell PowerEdge 6100 system hold up to four user-accessible,
half-height 5.25- or 3.5-inch devices, typically diskette,
tape, CD-ROM, or digital audio tape (DAT) drives. A
3.5-inch diskette drive and small computer system interface (SCSI) CD-ROM drive are standard in the first and
second drive bays. The diskette drive is controlled by the
system board’s built-in diskette drive controller, whereas
the CD-ROM drive is connected to the system board’s
built-in Ultra/Wide SCSI controller. Two additional
drives can be installed in the remaining two external
drive bays. See Figure 9-1 for a general view of the
various drives, control cables, and power cables in the
external drive bays.
WARNING: Before a trained service technician
accesses the inside of the computer, any and all
power supplies must be disconnected from their
power source, and the cables to the power supply
must also be disconnected. If this computer has
more than one power supply, disconnect both
power supply cords before servicing to avoid
electrical shock.

To remove or install drives in the external bays, you must
remove both computer covers and front bezel according
to the instructions in “Removing the Computer Covers”
and “Removing the Front Bezel” in Chapter 7.
To protect the inside of the computer from foreign particles, a plastic front-panel insert covers each empty
external drive bay. Before you install a drive in an empty
bay, you must first remove the front-panel insert.
Whenever you remove a drive, be sure to replace the
front-panel insert over the empty bay.

Most interface connectors are keyed for correct insertion;
that is, a notch or a raised tab on one connector matches a
tab or notch on the other connector. Keying ensures that
the pin-1 wire in the cable (indicated by the colored strip
along one edge of the cable) goes to the pin-1 ends of the
connectors on both ends.
CAUTION: When connecting an interface cable,
do not reverse the interface cable (do not place the
colored strip away from pin 1 of the connector).
Reversing the cable prevents the drive from operating and could damage the controller, the drive,
or both.
DC Power Cables
Installing SCSI Devices in the
External Bays
SCSI devices in the external drive bay (such as CD-ROM
drives and tape drives) are controlled by the Ultra/Wide
SCSI controller on the system board.
SCSI Configuration Information
Although SCSI devices are installed essentially the same
way as other devices, their configuration requirements
are different. To configure SCSI devices installed in the
external bays, follow the guidelines in the following
subsections.
SCSI ID Numbers
Each drive in the external drive bays must connect to a
4-wire DC power cable from the system power supply or
power-supply paralleling board. The connectors on this
cable are labeled “FD1,” “FD2,” “FD3,” “FD4,” and
“FD5.” Connectors FD1 through FD4 are used for
5.25-inch devices, whereas connector FD5 is used for the
standard 3.5-inch diskette drive. Before connecting a
drive to a power cable, refer to Figure 9-5 to identify the
correct cable connector to use for the drive.
Each device attached to the Ultra/Wide SCSI host adapter
must have a unique SCSI identification (ID) number
from 0 to 7.
When SCSI devices are shipped from Dell, the default
SCSI ID numbers are assigned as follows:
•
The computer’s built-in Ultra/Wide SCSI host
adapter is configured through the basic input/output
system (BIOS) as SCSI ID 7.
•
A SCSI tape drive is configured as SCSI ID 6 (the
default ID number for a tape drive).
•
A SCSI CD-ROM drive is usually configured as
SCSI ID 5.
NOTE: There is no requirement that SCSI ID numbers be
assigned sequentially or that devices be attached to the cable in
order by ID number.
system board

Device Termination
SCSI logic requires that the two devices at opposite ends
of the SCSI chain be terminated and that all devices in
between be unterminated.

Before installing SCSI devices in the computer, you must
configure the terminators on the SCSI device(s) to conform to the following guidelines:
•
A single SCSI device (such as the standard
CD-ROM drive) is terminated.
Dell PowerEdge 6100/200 System Installation and Troubleshooting Guide
•
those in the drive documentation. (See “SCSI Configuration Information” earlier in this section for
information on setting the drive’s SCSI ID number
and enabling termination [if required].) Change any
settings necessary for this system’s configuration.
If two or more SCSI devices are installed, connect
the devices as follows:
— Attach one of the devices to the end connector on
the SCSI cable, and leave the terminator enabled
on that device.
If the drive does not already have drive rails
attached, attach a drive rail to each side of the drive.
Orient the drive rails as shown in Figure 9-6. Secure
each drive rail to the drive with a screw in each of
the lower slotted screw holes on the drive rail.
— The other end of the SCSI cable connects to the
computer’s built-in Ultra/Wide SCSI host adapter
or to an optional SCSI host adapter card.
— Disable the terminators on all other devices you
attach to the cable.
The standard SCSI CD-ROM drive is configured as the
last device on the SCSI cable. Therefore, any additional
devices attached to the cable should have their terminators disabled.
See the documentation provided with the SCSI device for
information on disabling the device’s terminator.
SCSI Cable
CAUTION: Dell recommends that you use
only SCSI cables purchased from Dell. SCSI
cables purchased elsewhere are not guaranteed
to work reliably with the Dell PowerEdge 6100
systems.
Figure 9-6. Attaching Drive Rails

See “Removing the Computer Covers” and “Removing the Front Bezel” in Chapter 7.
The 50-pin SCSI cable has six connectors:
•
•
The connector at the end of the cable farthest away
from the other five connectors attaches to the SCSI
host adapter connector labeled “SCSI B” on the system board.
The five connectors on the cable attach to devices in
the external drive bays.
CAUTION: See “Protecting Against Electrostatic Discharge” in the safety instructions at
the front of this guide.
3.
The 50-pin “narrow” cable plugs in to the controller via
an adapter.
Installing a SCSI Device
To install an external SCSI device that uses the built-in
Ultra/Wide SCSI controller, follow these steps:
1.
Prepare the drive for installation.
Ground yourself by touching an unpainted metal surface on the back of the computer, unpack the drive,
and compare the jumper and switch settings with

drive, and then slide the drive slightly toward the
front of the chassis.
Refer to “DC Power Cables” earlier in this chapter to
determine the correct DC power cable connector to
use for the drive. Plug the DC power cable connector
into the 4-pin power input connector on the back of
the drive.
Select the connector on the SCSI cable that most easily reaches the new SCSI device, and press the
interface cable connector firmly into the drive’s
interface connector.
If you moved other drives at the beginning of this
step, snap them back into place.

Installing Drives in the Internal Bays
T
his chapter describes how to install and configure
small computer system interface (SCSI) hard-disk drives
in the computer’s six internal drive bays. See Chapter 9,
“Installing Drives in the External Bays,” for information
on installing SCSI CD-ROM drives and tape drives in the
external drive bays.
for servers that contain important data and programs for
an entire network of users. You can replace a failed drive
without forcing all users on the network to log off and
lose valuable time and possibly data. See “Removing and
Inserting a SCSI Hard-Disk Drive With the System Running” later in this chapter for details.
WARNING: Before a trained service technician
accesses the inside of the computer, any and all
power supplies must be disconnected from their
power source, and the cables to the power supply
must also be disconnected. If this computer has
more than one power supply, disconnect both
power supply cords before servicing to avoid
electrical shock.
CAUTION: Removing and installing hard-disk
drives with the system running is not supported for
systems without a PowerEdge Expandable RAID Controller host adapter card. Removing a drive in this
situation will result in a loss of data.
Dell PowerEdge 6100 systems include a SCSI backplane
board, which greatly simplifies cabling and configuration
for SCSI hard-disk drives. All SCSI identification (ID)
and termination for SCSI hard-disk drives are configured
by the SCSI backplane board, rather than on individual
drives.
In the standard Dell PowerEdge 6100 system configuration, the Ultra/Wide SCSI host adapter on the system
board controls the SCSI backplane board. When used in
combination with an optional PowerEdge Expandable
RAID Controller host adapter card, the SCSI backplane
board allows you to remove and insert hard-disk drives
without shutting down the system—an invaluable feature
Figure 10-1 illustrates the internal drive bays, SCSI
backplane board, and the Ultra/Wide SCSI cable. The
Ultra/Wide SCSI cable has two connectors:
•
The connector at one end attaches to the SCSI host
adapter connector labeled “SCSI A” on the system
board or to an optional SCSI host adapter card such
as the PowerEdge Expandable RAID Controller host
adapter card.
•
The connector at the other end of the cable attaches
to the connector labeled “SCSI” on the SCSI
backplane board.

Figure 10-1. Internal Drive Hardware
Installing SCSI Hard-Disk Drives
in the Internal Drive Bays
SCSI hard-disk drives are supplied by Dell in special drive
carriers that fit in the internal drive bays (see Figure 10-2).
The printed circuit board at the back of the drive carrier
acts as an interface between the SCSI hard-disk drive and
the SCSI backplane board.
SCSI Hard-Disk Drive Configuration
The SCSI backplane board provides termination for the
SCSI bus. None of the drives connected to the SCSI
backplane board should have their termination enabled.
All SCSI ID numbers for the drives are set by the SCSI
backplane board.
NOTE: Dell recommends that you use only drives that Dell
has tested and approved for use with the SCSI backplane
board.

Diagnostic Video Tests
T
he Video Test Group of the system diagnostics (see
Chapter 5, “Running the System Diagnostics”) consists
of the following seven tests, each of which verifies a particular video function or group of functions:
The following sections describe each of the tests in the
Video Test Group.
•
Video Memory Test — Checks the integrity of characters generated from data in the video memory.
Video Memory Test
•
Video Hardware Test — Checks the functions of the
cursor register and the horizontal and vertical retrace
bit registers.
•
Text Mode Character Test — Checks the video subsystem’s ability to present text mode data.
•
Text Mode Color Test — Checks the video subsystem’s ability to present color in text modes.
•
Text Mode Pages Test — Checks the video subsystem’s ability to map and present all available
video text pages on the monitor screen, one page at a
time.
•
Graphics Mode Test — Checks the video subsystem’s ability to present graphics mode data and
colors.
•
Color Palettes Test — Checks the video subsystem’s
ability to display all available colors.
•
Solid Colors Test — Checks the video subsystem’s
ability to show screens full of solid colors. Allows
you to check for missing color subpixels.
All of these tests, except the Video Memory Test and the
Video Hardware Test, are interactive. These interactive
tests display images on the monitor screen and require
the user to respond with the following steps:
1.
Examine a displayed image for correctness.
2.
If an image is correct, type y.
3.
If an image is incorrect, type n.
The Video Memory Test verifies the integrity of the
video memory either on the system board or on a video
expansion card. As the test runs, it describes which
64-kilobyte (KB) block of video memory is being tested.
When a test is complete, a message indicates whether the
video memory has passed or failed the test. This test does
not require any interaction on your part.
Video Hardware Test
The Video Hardware Test verifies the operation of the
cursor registers and the horizontal and vertical retrace bit
registers. When a test is complete, a message indicates
whether these registers have passed or failed the test.
This test does not require any interaction on your part.
Text Mode Character Test
The Text Mode Character Test consists of a group of subtests that display printable characters and character
attributes. The subtests check character quality and the
monitor’s ability to display the characters correctly on its
screen. A prompt at the bottom of each screen asks the
user to decide whether the display is satisfactory and to
respond by typing y or n.
If you respond affirmatively to each subtest, the Text
Mode Character Test passes. A negative response to any
subtest causes the test to fail.

Appendix C
Jumpers, Switches, and Connectors
T
his appendix provides specific information about the
jumpers on the system board. It also provides some basic
information on jumpers and switches and describes the
connectors and sockets on the various boards in the
computer.
Jumpers and Switches—
A General Explanation
Jumpers and switches provide a convenient and reversible way of reconfiguring the circuitry on a printed circuit
board. When reconfiguring the system, you may need to
change jumper settings on the system board. You may
also need to change jumper and/or switch settings on
expansion cards or drives.
Jumpers
Jumpers are small blocks on a circuit
board with two or more pins
emerging from them.
A jumper is referred to as open or unjumpered when the
plug is pushed down over only one pin or if there is no
plug at all. When the plug is pushed down over two pins,
the jumper is referred to as jumpered. The jumper setting
is often shown in text as two numbers, such as 1-2. The
number 1 is printed on the circuit board so that you can
identify each pin number based on the location of pin 1.
Figure C-1 shows the location and default settings of the
jumper blocks on the system board. See Table C-1 for the
designations, default settings, and functions of the system’s jumpers.
Switches
Switches control various circuits or functions in the
computer system. The switches you are most likely to
encounter are dual in-line package (DIP) switches, which
are normally packaged in groups of two or more switches
in a plastic case. Two common types of DIP switches are
slide switches and rocker switches (see the following
illustration).
Plastic plugs containing a wire fit
down over the pins. The wire connects
the pins and creates a circuit.
To change a jumper setting, pull the plug off its pin(s)
and carefully fit it down onto the pin(s) indicated.
CAUTION: Make sure the system is turned off
before you change a jumper setting. Otherwise,
damage to the system or unpredictable results
may occur.
slide switches
rocker switches
Each of these switches has two positions, or settings
(usually on and off). To change the setting of a slide
switch, use a small, pointed object such as a small screwdriver or a straightened paper clip to slide the switch to
the proper position. To change the setting of a rocker
switch, use the screwdriver or paper clip to press down
Jumpers, Switches, and Connectors

on the appropriate side of the switch. In either case, do
not use a pen, pencil, or other object that might leave a
residue on the switch.

Figure C-1 shows the location of the CLEAR PASSWORD switch on the system board.
3.
Move the CLEAR PASSWORD switch to the On
position.
4.
Replace the computer cover, reconnect the computer to its power source, and turn it on.
The existing passwords are not disabled (erased)
until the system boots with the CLEAR PASSWORD switch in the On position. However, before
you assign a new administrative and/or user password, you must set the CLEAR PASSWORD switch
back to the off position.
NOTE: For the full name of an abbreviation or acronym
used in this table, see the abbreviation and acronym list.
Disabling a Forgotten Password
The computer’s software security features include an
administrative password and a user password, which are
discussed in detail in Chapter 4, “Using the System Setup
Program,” of the system User’s Guide. A password jumper
on the system board enables these password features or
disables them and clears any password(s) currently in
use.
To disable a forgotten administrative password or user
password, a trained service technician must perform the
following steps:
1.
Disconnect the system from its power source and
remove the computer covers.
See “Removing the Computer Covers” in Chapter 7
for instructions.
CAUTION: See “Protecting Against Electrostatic Discharge” in the safety instructions at
the front of this guide.
C-10
Refer to “Jumpers and Switches—A General
Explanation” found earlier in this appendix for
jumper information.
NOTE: If you assign a new administrative and/or
user password with the CLEAR PASSWORD switch
still on, the system disables the new password(s) the next
time it boots.
5.
Repeat step 1.
6.
Move the CLEAR PASSWORD switch to the off position (away from the numbers).
7.
Replace the computer cover, reconnect the computer and peripherals to their power sources, and
turn them on.
8.
Have the user assign a new administrative and/or
user password.
To assign a new administrative password using the
system setup program, see “Assigning an Administrative Password” in Chapter 4 of the system User’s
Guide. To assign a new administrative password
using the system configuration utility, see “Security
Subsystems Group” in Chapter 5 of the system User’s
Guide.
To assign a new user password using the System
Setup program, see “Assigning a User Password” in
Chapter 4 of the system User’s Guide. To assign a new
user password using the system configuration utility,
see “Security Subsystems Group” in Chapter 5 of the
system User’s Guide.
