Safety Instructions
U
se the following safety guidelines to help protect
your computer system from potential damage and to
ensure your own personal safety.
W
hen 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.
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.
3. Touch an unpainted metal surface on the com-
puter chassis, such as the power supply, before
touching anything inside the computer.
While you work, periodically touch an unpainted
metal surface on the computer chassis to dissipate
any static electricity that might harm internal
components.
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 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.
v
Page 5
In addition to the preceding precautions, you can also
take the following steps to prevent damage from electrostatic discharge (ESD):
•
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.
•
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.
W
hen Using the Computer
System
•
To help prevent electric shock, plug the computer
and peripheral power cables into properly grounded
power sources. These cables are equipped with
three-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 three-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.
As you use the computer system, observe the following
safety guidelines:
•
Be sure the monitor and attached peripherals are
electrically rated to operate with the AC power available in your location.

Introduction
D
ell® PowerEdge™ 4100/180 and Dell PowerEdge 4100/200 systems are high-speed, upgradable
servers that offer a number of significant service and
upgrade features.
The Dell PowerEdge 4100 systems’ service features
make troubleshooting easy and effective. Every system
includes CD-based Dell diagnostics software for diagnosing system problems if the system can boot. The
embedded server management hardware monitors temperatures and voltages throughout the system and notifies
you if the system overheats or if one of the system cooling fans malfunctions. If the system has an optional
power-supply paralleling board and redundant power
supplies, the server management hardware also monitors
the status of the power supplies.
The Dell PowerEdge 4100 system chassis simplifies
removing and replacing computer components. Processor
and memory upgrades can be performed without removing the system board. The Dell-designed small computer
system interface (SCSI) backplane board and hard-disk
drive carriers eliminate the extensive cabling and drive
configuration usually required for a SCSI subsystem. The
plastic drive rails attached to devices mounted in the
external drive bays allow you to remove devices without
removing a single screw.
Among the many upgrade options offered for the Dell
PowerEdge 4100 systems are a secondary microprocessor, additional main memory, a variety of
expansion-card options (including the Dell PowerEdge
Expandable RAID Controller host adapter), and additional SCSI CD-ROM, tape, and hard-disk drives.

ystem 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 sounds: for example, one beep, followed by a
second beep, and then a burst of three beeps (code 1-1-3)
means that the computer was unable to read the data in
nonvolatile random-access memory (NVRAM). This
information is valuable to the Dell support staff if you

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

The three light-emitting diode (LED) indicators adjacent
to each of the six SCSI hard-disk drive bays provide
information on the status of the SCSI hard-disk drives.
The SCSI backplane firmware controls the drive online
and drive fault indicators, while the drive access indicator
is usually controlled by the drive itself.
Table 3-4 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,
then the “drive online” pattern.

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
•
Input errors
•
Device drivers that may conflict with certain application programs
•
Interrupt conflicts between devices
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.

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, the user should read its
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.
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. Users should always read
the installation instructions before running a program’s
installation routine.
When users run the installation routine, they should be
prepared to respond to prompts for information about
how the computer’s operating system is configured, what
type of computer they have, and what peripherals are
connected to the computer.

The following subsections discuss errors that can occur
as a result of software operation or configuration.
The user 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
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.

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 or not 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.

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.
F
eatures 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
•
Options to temporarily suspend testing if an error is
detected or to terminate testing when an adjustable
error limit is reached

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.

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 Hard-Disk Drives (Non-SCSI)
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

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

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

This subtest checks all available RAM. The Comprehensive Memory Test also 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
•
A parity check that verifies the ability of the memory
subsystem to detect errors
•
A refresh check, to verify that the dynamic RAM
(DRAM) is being recharged properly
The Cache Memory Test confirms the functionality of the
computer’s cache controller chip and the cache memory.
The RAM Test Group subtests check all the directly
addressable RAM.
Subtests
Three subtests are available for RAM: the Quick Memory Test, the Comprehensive Memory Test, and the
Cache 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.
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.)
Running the System Diagnostics 5-11
Page 41
•
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 Instru-
mentation Package (HIP) server management
program. See Chapter 3, “Messages and Codes,” for
more information on this program.
S
ystem Set Test Group
The subtests in the System Set Test Group check the
computer’s basic system board components and verify
their related functions.
Subtests
The subtests that constitute the System Set Test Group
and the computer functions they confirm follow:
•
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.
•
CMEM Confidence 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.
•
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).
•
System 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.
•
Interrupt Controller Test
Generates an interrupt on each interrupt request
(IRQ) line to verify that devices using that line can
communicate with the microprocessor and that the
interrupt controllers send the correct memory
addresses to the microprocessor.
•
Reset Button Test
Confirms that the reset button works.
•
System Speaker Test
Checks the functionality of the speaker by generating eight tones.
•
Coprocessor Calculation Test
Checks the use of different types of numbers and the
math coprocessor’s ability to calculate correctly.
•
Coprocessor Duty Cycle Test
Tests the math coprocessor’s ability to perform com-
plex mathematical operations.
•
Coprocessor Error Exception Test
Verifies the math coprocessor’s ability to handle
errors and to send IRQs to the microprocessor.
•
Multiprocessor Test
For systems with multiprocessors, confirms that the
secondary microprocessor is operational.
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.
5-12 Dell PowerEdge 4100/180 and 4100/200 Systems Installation and Troubleshooting Guide
Page 42
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 word 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 does not
resolve a problem.
•
The computer’s clock/calendar stops.
•
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 System Timers Test,
followed by the System Speaker Test.
•
If a peripheral device appears to malfunction, run the
Interrupt Controllers 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.
V
ideo 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.
Subtests
The eight subtests in the Video Test Group and the video
functions they confirm follow:
•
Vid e o Memory Te st
Checks the read/write capability of video memory in
various video modes.
•
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.

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.
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
Ch aracter Test, Text Mode Co l or Te s t , Te x t M ode
Pages Test, and Graphics Mode Test.
K
eyboard Test Group
The subtests in the Keyboard Test Group verify the correct operation of the keyboard and the keyboard
controller chip.
Subtests
The five keyboard subtests and the keyboard functions
they confirm follow:
•
Keyboard Controller Test
Confirms the ability of the keyboard controller chip
to communicate with the keyboard and the programming of the controller chip
•
Keyboard Key Sequence Test
Verifies that the keys on the keyboard function correctly when you press the keys in a predefined order
•
Keyboard Interactive Test
Checks the internal microcode of the keyboard and
the external interface of the keyboard controller chip
for a malfunctioning key
•
Stuck Key Test
Checks the internal microcode of the keyboard and
the external interface of the keyboard controller chip
for a repeating-key signal
•
External Key Pad Test
Checks the contact beneath the key for an electrical
impulse to ensure that the key is working properly
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.
5-14 Dell PowerEdge 4100/180 and 4100/200 Systems Installation and Troubleshooting Guide
Page 44
•
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.
M
ouse 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.
Subtests
There are no subtests for the Mouse Test Group.
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.
D
iskette 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 four 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?
Very 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.
Running the System Diagnostics 5-15
Page 45
•
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.
H
ard-Disk Drives (Non-SCSI) Test
Group
The subtests in the Hard-Disk Drives (Non-SCSI) Test
Group check the functionality of up to two hard-disk
drives of any capacity. The subtests check the storage
capability of a drive as well as the hard-disk drive controller (which affects the ability to read from and write to
the drive). The subtests are for all hard-disk drive types
except for SCSI drives.
NOTE: Because the Dell PowerEdge 4100 system supports only SCSI hard-disk drives, use the SCSI Devices
Test Group (described in “SCSI Devices Test Group”
found later in this chapter) to test any hard-disk drive
installed in the computer.
S
erial/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
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 Serial 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.
Subtests
The four subtests in the Serial/Infrared Ports Test Group
and the port functions they confirm follow:
•
Serial/Infrared Baud Rate Test
Checks the baud rate generator in each serial communications chip against the computer’s clock
•
Serial/Infrared Interrupt Test
Checks the serial port’s ability to send IRQs to the
microprocessor
•
Serial/Infrared Internal Transmission Test
Checks several internal functions of the serial port
using the internal loopback mode of the serial communications chip
•
Serial External Transmission 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
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
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:
•
If a peripheral works intermittently or produces
intermittent errors, the port may be faulty.
•
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
System Setup program, and if necessary, run the
appropriate subtest in the Serial/Infrared Ports Test
Group.
P
arallel 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 this 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 Parallel Internal Test.)
NOTE: If an external loopback connector is not attached
to the parallel port, the Parallel External Loopback Test
will fail for that port and the results of this test should
therefore be ignored.

CSI Devices Test Group
The subtests in the SCSI Devices Test Group check the
functionality of up to four 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, except for the Audio Output Test, require a CD with data
tracks. The Audio Output Test requires a CD with audio tracks.
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.

Subtests
The seven subtests in the SCSI Devices Test Group and
the drive functions they confirm follow:
•
Internal Diagnostic
Causes the device to run its internal self-test.
•
Seek Test
Checks the device’s ability to search for a specified
track on the device and to position its read/write
heads to all tracks.
•
Read 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.
•
Write Test
Positions the read/write heads at each block of the
device and verifies that all tracks on the device can
be written to correctly.
•
Audio Output Test
Causes the CD-ROM drive to begin playing the first
audio track on an audio CD. To determine whether
the test passed, listen to the audio output of the drive.
NOTE: To conduct the Audio Output Test, you must
select it individually. It will not run as part of the test
group.
•
Eject Removable Media
Causes a CD-ROM drive to eject its CD or a SCSI
tape drive to eject its tape cartridge.
•
Display Information
Displays a screen of information about each SCSI
host adapter in the computer, the resources allocated
to each SCSI host adapter, and a list of target devices
attached to the SCSI host adapter.
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.
These are the most common symptoms that might prompt
you to test a SCSI device:
•
A SCSI hard-disk drive fails during the boot routine.
•
Seek errors are reported by the operating system or
application programs.
•
An error message appears on the screen stating that
the computer cannot read from or write to a SCSI
device.
•
Data on a SCSI device is corrupted or lost; this problem may be intermittent. Once saved by a program,
files cannot be properly recalled.

In Figures 7-4 and 7-5, the computer cover is removed to
provide interior views from the left and right sides. These
illustrations also identify features on the front and back
of the computer. Refer to them to locate interior features
and components discussed later in this guide.
When you look inside the computer, note the direct current
(DC) power cables leading from the power supply or
optional 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 non-SCSI drives, an interface cable connects
each drive to an interface connector on the system board
or on an expansion card. For SCSI devices, two interface
cables connect 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 eight expan-
sion-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, an expansion card, or a drive. For information on the system board jumpers, see Appendix C,
“Jumpers and Switches.”

Installing an Expansion Card
Follow this general installation procedure:
1. If you are installing an ISA expansion card, start
the EISA Configuration Utility, and add the new
expansion card to the configuration information.
See Chapter 5, “Using the EISA Configuration Utility,” in the system User’s Guide for instructions.
NOTES: If you are installing an EISA expansion
card, you should normally run the EISA Configuration Utility after installing the expansion card.
If you are installing a PCI expansion card, your system automatically performs any required PCI
configuration tasks during the boot routine.
2. Prepare the expansion card for installation, and
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.
See the documentation that came with the expansion
card for information on configuring the card, making
internal connections, or otherwise customizing it for
the system.
3. Unscrew and remove the metal filler bracket that
covers the card-slot opening for the expansion
slot you intend to use.
4. If the expansion card is full-length, check that the
locking cam on the corresponding locking card
guide is in the raised or “unlocked” position.
Insert the end of the expansion card in the card
guide slot and lower the card into the chassis.
5. Insert the card-edge connector firmly into the
expansion-card connector on the chassis.
6. When the card is firmly seated in the connector
and the card-mounting bracket is flush with the
brackets on either side of it, secure the bracket
with the screw you removed in step 3.
If the expansion card is full-length, close the locking
cam on the card guide to secure the card.
7. Connect any cables that should be attached to the
card.
See the documentation that came with the card for
information about cable connections.
8. Replace the left computer cover, reconnect the
computer and peripherals to their power sources,
and turn them on.
9. Start the EISA Configuration Utility and add the
new expansion card to the configuration.
See Chapter 5, “Using the EISA Configuration Utility,” in the system User’s Guide for instructions.
NOTE: If you installed a PCI expansion card, the
system automatically performs any required PCI
configuration tasks during the boot routine.

A
dding Memory
The eight dual in-line memory module (DIMM) sockets on
the system board can accommodate 64 to 1024 megabytes
(MB) of dynamic random-access memory (DRAM). The
Dell PowerEdge 4100 systems use 72-bit, buffered,
extended-data out (EDO) DIMMs in these 168-pin sockets. The DIMM sockets are located near the right edge of
the system board (see Figure 8-1).
Memory Upgrade Kits
The system is upgradable to 1024 MB by installing combinations of 32- and 128-MB DIMMs. The DIMMs
should be rated at 60 nanoseconds (ns) or faster.
Table 8-1 shows several sample memory configurations.
Memory upgrade kits can be purchased from Dell as
needed.
DIMM Installation Guidelines
Starting with the socket farthest from the microprocessor
sockets, the DIMM sockets are labeled “DIMM A”
through “DIMM H” (see Figure 8-1).
When installing DIMMs, follow these guidelines:
•
Install a DIMM in socket DIMM A before socket
DIMM B, socket DIMM B before socket DIMM C,
and so on.
•
If you install different sizes of DIMMs, install them
in order of descending capacity, beginning with
socket DIMM A.
•
DIMMs need not be installed in pairs.
Table 8-1 illustrates several sample memory configurations based on these guidelines.

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
check all the installed DIMMs to make sure they are
seated properly in their sockets. Then repeat step 4.
CAUTION: See “Protecting Against Electrostatic Discharge” in the safety instructions at
the front of this guide.
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
2. Locate the DIMM sockets in which you will
install or replace DIMMs.
Figure 8-1 shows the location of the DIMM sockets
on the system board.
3. Install or replace the DIMMs as necessary to
reach the desired memory total.
Follow the instructions in “Installing DIMMs” or
“Removing DIMMs” found later in this section, as
appropriate.
4. Replace the left computer cover, reconnect the
computer and peripherals to their power sources,
and turn them on.
After the system completes the power-on self-test
(POST) routine, it runs a memory test that displays
to that effect, ending with the following words:
Press <F1> to continue; <F2> to enter
System Setup.
5. Press <F2> to enter the System Setup program, and
check the
SYSTEM MEMORY
category in the system
data box on the System Setup screens.
The system should have already changed the value in
SYSTEM MEMORY
the
category to reflect the newly
installed memory. Verify the new total.
NOTE: The value of
SYSTEM 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 DIMMs
may not be installed properly. Repeat this procedure
again, checking to make sure the DIMMs are firmly
seated in their sockets.

Installing DIMMs
Install DIMMs starting with socket DIMM A, located
farthest from the microprocessor sockets, and working
towards DIMM H. If a DIMM is already installed in the
socket you need, you must remove it. Follow the instructions in the next subsection, “Removing DIMMs,” if
appropriate.
To install a DIMM, follow these steps:
1. Press the ejectors on the DIMM socket down and
outward as shown in Figure 8-4 to allow the
DIMM to be inserted in the socket.
2. Align the DIMM’s edge connector with the slot in
the center of the DIMM socket, and insert the
DIMM in the socket.
The card-edge connector on the DIMM is keyed
using two notches so that the DIMM can be installed
in the socket in only one way (see Figure 8-4).
3. Press down on the two outer edges of the DIMM
with your thumbs while pulling up on the ejectors
with your index fingers to lock the DIMM into the
socket.
When the DIMM is properly seated in the socket, the
ejectors on the DIMM socket should align with the
ejectors on the other DIMM sockets.

pgrading the Microprocessor or
Installing a Secondary
Microprocessor
In addition to the zero insertion force (ZIF) socket for the
primary microprocessor on the system board, there is a
second ZIF socket to accommodate a secondary microprocessor. The secondary microprocessor must have the
same operating frequency as the primary microprocessor.
For example, if the system has a 180 megahertz (MHz)
Pentium Pro primary microprocessor, your secondary
microprocessor must also be a 180-MHz Pentium Pro
microprocessor.
NOTE: If you are upgrading a system by installing a secondary microprocessor, you must order a microprocessor
upgrade kit from Dell. The upgrade kit from Dell contains the correct version of the microprocessor for use as
a secondary microprocessor. Not all versions of the Pentium Pro microprocessor will work properly as a
secondary microprocessor.
The following items are included in a microprocessor
upgrade kit:
•
The new microprocessor chip
•
A new heat sink
•
A new heat sink clip
•
A new snap-in badge
Use the following procedure to remove the old microprocessor and install the upgrade or to add a second
microprocessor.
1. Remove the left computer cover.
See “Removing the Computer Covers” in Chapter 7.
2. Remove the metal clip that secures the heat sink
to the microprocessor socket.
CAUTION: Never remove the heat sink from a
microprocessor unless you intend to remove
the microprocessor. The heat sink is necessary
to maintain proper thermal conditions.
WARNING: The microprocessor chip and heat
sink can get extremely hot. Be sure the microprocessor has had sufficient time to cool before
you touch it.
Press down on the folded part of the clip with a small
screwdriver to release the clip (see Figure 8-6).

If any of the pins on the microprocessor appear bent,
see Chapter 11, “Getting Help,” for instructions on
obtaining technical assistance from Dell.
6. Align the pin-1 corner of the microprocessor chip
(see Figure 8-8) with the pin-1 corner of the
microprocessor socket.
NOTE: Identifying the pin-1 corners is critical to
positioning the chip correctly.
Identify the pin-1 corner of the microprocessor by
turning the chip over and locating the tiny gold finger that extends from one corner of the large central
7. Install the microprocessor chip in the socket (see
Figure 8-9).
CAUTION: Positioning the microprocessor
incorrectly can permanently damage the chip
and the computer when you turn on the
system.
If the release lever on the microprocessor socket is
not all the way up, move it to that position now.
With the pin-1 corners of the chip and socket
aligned, set the chip lightly in the socket and make
sure all pins are matched with the correct holes in
the socket. Because the system uses a ZIF microprocessor socket, there is no need to use force (which
could bend the pins if the chip is misaligned). When
the chip is positioned correctly, it should drop down
into the socket with minimal pressure.
CAUTION: When placing the microprocessor
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.
When the chip is fully seated in the socket, rotate the
socket release lever back down until it snaps into
place, securing the chip.

The operating life of the battery ranges from two to five
years, depending 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). The battery may need replacing if an incorrect time or date is displayed during the
boot routine along with a message such as:
Time-of-day not set — please run SETUP
program
Strike the F1 key to continue, F2 to run
the setup utility
or
Invalid configuration information — please
run SETUP program
Strike the F1 key to continue, F2 to run
the setup utility
To determine if the battery 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
battery.
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 battery.
If the system is turned off for long periods of time (for
weeks or months), the NVRAM may lose its system configuration information. This situation is not caused by a
defective battery.
The system can be operated without a battery; however,
the system configuration information maintained by the
battery 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 battery is replaced.
The battery is a 3.0-volt (V), coin-cell CR2450-type battery. To remove the battery, follow these steps:
1. If possible, enter the System Setup program and
make a printed copy of the system setup screens.

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.
interface connector
header connector
key (cut-off pin)
Figure 9-4. Header Connector
Most interface connectors are keyed for correct insertion;
that is, a notch or a missing pin on one connector matches
a tab or a filled-in hole 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. A header con-
nector is usually keyed by the omission of one of its pins
with the corresponding hole filled in on the connector on
the cable (see Figure 9-4).
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.

nstalling 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/
Narrow 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.
Installing Drives in the External Bays 9-3
Page 87
SCSI ID Numbers
Each device attached to the Ultra/Narrow 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/Narrow 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.
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.
•
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.
— The other end of the SCSI cable connects to the com-
puter’s built-in Ultra/Narrow SCS I 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 4100
systems.
The 50-pin Ultra/Narrow SCSI cable has five connectors:
•
The connector at the end of the cable farthest away
from the other four connectors attaches to the SCSI
host adapter connector labeled “SCSI CD-ROM” on
the system board.
•
The four connectors on the cable attach to devices in
the external drive bays.
Installing a SCSI Device
To install an external SCSI device that uses the built-in
Ultra/Narrow 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
those in the drive documentation. (See “SCSI Configuration Information” found earlier in this chapter
for information on setting the drive’s SCSI ID number and enabling termination [if required].) Change
any settings necessary for this system’s configu-
ration.
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.

2. Remove the computer covers and front bezel.
See “Removing the Computer Covers” and “Remov-
ing the Front Bezel” in Chapter 7.
CAUTION: See “Protecting Against Electrostatic Discharge” in the safety instructions at
the front of this guide.
3. Slide the new drive into its bay until it snaps
securely into place.
If necessary, you can adjust drive alignment by
repositioning one or both rails.
4. Connect a DC power cable and one of the connectors on the Ultra/Narrow SCSI cable to the back
of the drive (see Figure 9-7).
If other installed drives are in the way, temporarily
move them out of the way. Press in on the plastic
drive rails at the front of the bay to disengage a
drive, and then slide the drive slightly toward the
front of the chassis.
Refer to “DC Power Cables” (found 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 Ultra/Narrow 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.)
Dell PowerEdge 4100 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 4100 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
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” found later in this chapter for details.
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 will result in
a loss of data.
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 BACKPLANE” 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.

nstalling 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 harddisk drive and 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.
10-2 Dell PowerEdge 4100/180 and 4100/200 Systems Installation and Troubleshooting Guide
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.

Removing and Inserting a SCSI HardDisk Drive With the System Running
If the Dell PowerEdge 4100 system has a PowerEdge
Expandable RAID Controller host adapter card installed
and connected to the SCSI backplane board, you can
remove and insert SCSI hard-disk drives while the system is running.
Before attempting to remove or insert a drive while the
system is running, see the documentation for the Poweredge Expandable RAID Controller host adapter card to
ensure that the SCSI host adapter is configured correctly
to support drive removal and insertion.
CAUTION: Removing and installing SCSI harddisk drives with the system running is not
supported for systems without a PowerEdge Expandable RAID Controller host adapter. Removing a drive
in this situation will result in a loss of data.

CSI Hard-Disk Drive Indicator Patterns
The three light-emitting diode (LED) indicators adjacent
to each of the six SCSI hard-disk drive bays provide
information on the status of the SCSI hard-disk drives.
The SCSI backplane firmware controls the drive online
and drive fault indicators, whereas the drive access indicator is usually controlled by the drive itself.
Table 10-1 lists the various drive indicator patterns. Different patterns are displayed as drive events occur. 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 removal”
pattern. After the replacement drive is installed, the
“drive being prepared for operation” pattern appears,
then the “drive online” pattern.
