Chapter 1
System Overview
The Dell
®
PowerEdge® 2100/180 and 2100/200 systems, covered in this manual are high-speed, upgradable, server systems, which use the Intel® Pentium®
Pro family of microprocessors. PowerEdge 2100 systems incorporate the highperformance peripheral component interconnect (PCI) local bus as well as the
extended industry-standard architecture (EISA) expansion bus. These buses are
built into the system board, which also integrates a Pentium Pro microprocessor and all
other elements of the basic computer system.
The microprocessor module is installed in a zero insertion force (ZIF) socket on
the system board. This allows upgrading of the system board to a faster, more
powerful microprocessor when one becomes available. Contact Dell for information about Dell-supported microprocessor upgrades.
The Pentium Pro microprocessor contains a built-in clock multiplier circuit,
which increases the internal operating frequency to a multiple of the system
clock frequency. The microprocessors for each of these systems and their operating frequencies are as follows:
• Dell PowerEdge 2100/180 system — 180 MHz derived from a system clock
frequency of 60 MHz
• Dell PowerEdge 2100/200 system — 200 MHz derived from a system clock
frequency of 66 MHz
System Overview

System Memory
System memory has a minimum of 16 MB of 72-bit wide, buffered, EDO-type
memory. The system memory capacity can be expanded up to 256 MB by using
combinations of 16-, 32-, and 128-MB buffered, EDO-type dual in-line memory
modules (DIMMs).
The system board has four, 168-pin DIMM sockets. The DIMMs can be mixed.
The socket population rules are as follows:
• Populate the DIMM sockets in order from DIMM_A (lower) to DIMM_D
(upper).
• The DIMMs should be rated at 60 nanoseconds (ns) or faster. All of the system memory operates at the speed of the slowest DIMM installed.
• The largest capacity DIMM should be in socket DIMM_A with the smaller
capacity DIMMs installed in decreasing sizes toward socket DIMM_D.
The 72-bit wide, buffered, EDO DIMMs support the ECC feature that detects
memory errors and corrects single-bit memory errors. The ECC feature provides more reliable memory and less downtime. The ECC feature is built into
the memory controller on the system board.
See “DIMMs” in Chapter 4 for information on removing and replacing DIMMs.
Advanced Expansion Subsystem
The computer system offers advanced expansion subsystems that can support a
mixture of traditional EISA expansion cards, Plug and Play ISA expansion cards,
and PCI expansion cards. The EISA Configuration Utility included with the system
provides a means of avoiding resource conflicts that might arise from such an
arrangement.
After all legacy cards have been configured with the EISA Configuration Utility,
the system automatically assigns any required memory space, IRQ lines, and
DMA channels to any installed Plug and Play ISA expansion cards and PCI
expansion cards the next time the system is rebooted. Chapter 5, “Using the
EISA Configuration Utility,” in the User’s Guide describes the EISA Configuration Utility and provides instructions for using it to configure the system.
The six expansion-card slots include three EISA expansion-card connectors and
three PCI expansion-card connectors. The expansion-card connectors are
located on the system board (see Figure 1-11).
Integrated Server Management
The system board contains integrated server management circuitry that monitors whether the system cooling fan is running, as well as critical system
voltages and temperatures. The integrated server management circuitry works
in conjunction with the Intel LANDesk® Server Management suite.
1-6
Dell PowerEdge 2100/180 and 2100/200 Systems Service Manual
Video Controller
The video subsystem is built into the system board and consists of a high-speed,
high-resolution VGA-compatible video subsystem. The video controller is connected to the PCI local bus. The standard video subsystem contains 1 MB of
video memory (the video memory size is not upgradable).
Maximum noninterlaced resolutions are 640 x 480 pixels with 16.7 million colors or 800 x 600 pixels with 65,536 colors.
Maximum interlaced resolution is 1024 x 768 pixels with 256 colors.
Integrated SCSI Controller
A single-integrated SCSI controller provides an ultra (fast-20) wide, SCSI interface through a 68-pin connector on the system board. The integrated SCSI
controller attaches to the PCI bus to provide a high-performance SCSI bus.
The integrated SCSI controller provides control for the three SCSI hard-disk
drives in the SCSI hard-disk drive cage, the CD-ROM drive in the middle
externally-accessible drive bay and a SCSI drive installed in the lower
externally-accessible drive bay.
SCSI Hard-Disk Drives
A SCSI hard-disk drive cage is located under the externally-accessible drive bays at
the front of the computer (see Figure 1-4). The SCSI hard-drive cage can contain up
to three, 1.6-inch-high, SCSI hard-disk drives (either fast/wide or ultra [fast-20]
wide). These SCSI hard-disk drives mount vertically. The SCSI hard-disk drive bays
are populated from left to right (facing the front of the computer), so that the SCSI
terminator jumper is accessible on the leftmost drive installed (last drive on the SCSI
channel).
NOTE: The externally-accessible drive bays at the front of the computer are
normally used for diskette drives, CD-ROM drives, and/or tape drives. Harddisk drives should be installed in the SCSI hard-disk drive cage. For detailed
information about installing externally-accessible drives, see Chapter 8, “Installing
Drives in the External Bays,” in the User’s Guide. For detailed information about
installing SCSI hard-disk drives, see Chapter 9, “Installing Drives in the Internal
Bays,” in the User’s Guide.
SCSI Configuration Guidelines
Although SCSI devices are installed essentially the same way as other devices,
their configuration requirements are different. To configure your SCSI subsystem, follow the general guidelines offered in the following subsections.
System Overview
1-7
SCSI ID Numbers
Each device attached to the SCSI host adapter must have a unique SCSI ID
number from 0 to 15. See Chapter 9, “Installing Drives in the Internal Bays” in
the User’s Guide for additional SCSI addressing information.
NOTE: Any narrow SCSI devices installed in the external drive bays will
require SCSI ID numbers less than 7.
When SCSI devices are shipped from Dell, the default SCSI ID numbers are
assigned as follows:
• The computer’s built-in SCSI controller is configured through the BIOS as
SCSI ID 7 (the default ID number for a host adapter) if the system includes
a CD-ROM or tape drive.
NOTE: If only wide SCSI hard-disk drives are connected to the built-in SCSI
controller (no CD-ROM or tape drives), it may be configured as SCSI ID
15.
• A SCSI CD-ROM drive (installed in an externally-accessible drive bay) is
configured as SCSI ID 5.
• A SCSI tape drive (if installed) is configured as SCSI ID 6.
• The drive you intend to use as your boot device should be configured as SCSI
ID 0. You can configure any additional hard-disk drives to any of the stillavailable SCSI ID numbers.
• If Dell installs additional SCSI hard-disk drives in the system, they will be
configured as SCSI ID 1 and SCSI ID 2.
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
Before installing SCSI devices, you must configure the termination on the
device(s) and for the built-in SCSI controller according to the guidelines listed
in the following text.
SCSI logic requires that termination be enabled for the two devices at opposite
ends of the SCSI chain and disabled for all devices in between. To that end,
regardless of whether you are installing internal or external devices, use the following guidelines:
• The built-in SCSI controller has active termination — no action is required.
• When the SCSI hard-disk drives are installed by Dell, termination is set to
enabled on the SCSI hard-disk drive installed in the left bay of the SCSI
hard-disk drive cage. Termination should be disabled on any other drives
installed in the SCSI hard-disk drive cage. Figure 1-5 shows some examples
of SCSI termination jumpers.
1-8
Dell PowerEdge 2100/180 and 2100/200 Systems Service Manual
• If you install an optional SCSI controller card to control the CD-ROM drive
and any other SCSI device in the externally-accessible drive bays, you must
enable termination for the SCSI controller card and the SCSI device at the
end of the SCSI interface cable (preferably the CD-ROM drive). See the
documentation that came with your SCSI controller card for instructions.
Figure 1-5 shows an example of a SCSI termination jumper on a CD-ROM
drive.
NOTE: When you install or remove a termination jumper, do not move or
remove any other jumpers installed on the drives.

System Unit
The following subsections provide service-related information about the
computer.
System Power Supply
The 230-W system power supply can operate from an AC power source of
115 VAC at 60 Hz or 230 VAC at 50 Hz. The system power supply provides the
DC operating voltages and currents listed in Table 1-1.
NOTE: The power supply produces DC voltages only under its loaded condition. Therefore, when you measure these voltages, the DC power connectors
must be connected to their corresponding power input connectors on the system
board or drives.

Chapter 2
Basic Troubleshooting
T
his chapter describes basic troubleshooting procedures that can help you
diagnose a computer system problem. These procedures can often reveal the
source of a problem or indicate the correct starting point for troubleshooting the
system. A brief explanation of how to load and start the diskette-based diagnostics is located at the end of the chapter. Dell recommends that you perform the
following procedures in the order they are presented in this manual.
Initial User Contact
When you first contact a user who has a problem, ask the user to describe the
problem and the conditions under which it occurs. A verbal description can
often indicate the cause of a problem or indicate the appropriate troubleshooting
procedure to use. After the user describes the problem, follow these steps:
1. Ask the user to back up any data on the hard-disk drive if the system’s
condition permits.
Appendix C, “Maintaining the System,” in the User’s Guide provides information about backing up data.
2. Ask the user to try to duplicate the problem by repeating the operations
he or she was performing at the time the problem occurred.
Can the user duplicate the problem?
Yes. Proceed to step 3.
No. Proceed to the next section, “External Visual Inspection.”
3. Observe the user to determine if he or she is making an error, such as
typing an incorrect key combination or entering a command
incorrectly.
Is the problem a result of user error?
Yes. Instruct the user in the proper procedure, or direct him or her to the
appropriate user documentation for the correct procedure.
No. Proceed to the next section, “External Visual Inspection.”
Basic Troubleshooting
2-1
External Visual Inspection
The external visual inspection is a quick inspection of the exterior of the system
unit, the monitor, the keyboard, any peripherals, and cables. While performing
the visual inspection, make any necessary corrections. To perform the external
visual inspection, follow these steps:
1. Turn off the system unit, the monitor, and all peripherals.
2. Verify that all power cables are properly connected to the system unit,
the monitor and peripherals, and their power sources.
3. Verify that the keyboard and mouse interface cables are firmly
attached to the proper connectors on the back of the system unit.
For a PS/2-compatible mouse, the keyboard and mouse interface cable connectors are identical except for their labels. If needed, see “System
Features” in Chapter 1.
For a serial mouse, the mouse interface cable must be firmly attached to one
of the serial port connectors, and its captive screws must be secure enough
to ensure a firm connection.
4. If present, verify that any network cables are attached properly.
5. Verify that any devices attached to the serial and parallel port connectors are properly connected.
Each of the serial and parallel interface cables must be firmly attached to an
appropriate connector on the back of the system unit as well as to the interface connector on the device. The captive screws that secure these
connectors at each end of the interface cable must be secure enough to
ensure a firm connection.
6. Verify that the video interface cable is firmly attached to the connector
on the back panel or to a video expansion card and to the connector on
the back of the monitor.
For proper connection of the video monitor, see the documentation for the
monitor.
7. Inspect all external monitor controls for any obvious damage or
improper settings.
For proper settings of the video monitor controls, see the documentation for
the monitor.
8. Inspect the keyboard to ensure that no keys are sticking.
If one or more keys are sticking, it may be necessary to replace the
keyboard.
2-2
Dell PowerEdge 2100/180 and 2100/200 Systems Service Manual
9. Inspect the exterior of the system unit, including all controls and indicators, and all user-accessible data storage devices for any signs of
physical damage.
Does the inspection reveal any problems?
Yes. Proceed to the appropriate procedure in Chapter 4, “Removing and
Replacing Parts.”
No. Proceed to the next section, “Observing the Boot Routine.”
Observing the Boot Routine
After you have performed an external visual inspection as described in the previous section, you should boot the system and, while the boot routine is
running, observe the system for any indications of problems.
NOTE: Most of the steps in this procedure require observation of system functions and indications, some of which can occur simultaneously. It may be
necessary to reboot the system several times in order to complete all of these
steps.
To observe problem indications during the boot routine, follow these steps:
1. Insert the diagnostics diskette into drive A. Turn on all peripherals and
the system unit. If the system unit is already on, press the reset button
or <CTRL><ALT><DEL> to reboot the system.
2. Check the power supply fan.
Does the fan run normally?
Yes. Proceed to step 3.
No. Troubleshoot the system power supply.
3. Watch the Num Lock, Caps Lock, and Scroll Lock indicators on the
upper-right corner of the keyboard. After all three indicators flash
momentarily, the Num Lock indicator should light up and remain on.
Do these indicators flash on and off within approximately ten seconds after
the boot routine starts?
Yes. Proceed to step 4.
No. Troubleshoot the system power supply. If the troubleshooting procedure
indicates that the system power supply is operational, troubleshoot the
memory.
Basic Troubleshooting
2-3
4. During the boot routine, observe the system for any of the following:
• Diskette-drive and hard-disk drive access indicators: These indicators
light up in response to data being transferred to or from the drives. If
either of these indicators fails to light up during the boot routine, troubleshoot the diskette drive or hard-disk drive subsystem, as appropriate.
• System error messages: These messages can indicate problems or provide status information. If a system error message is displayed, see
Table 3-2.
• Beep codes: A beep code is a series of beeps that indicates an error condition. If the system emits a beep code, see Table 3-1.
NOTE: The system beeps once during the boot routine. This single beep is
normal and is not a beep code.
5. Observe the monitor screen for the Diagnostics Menu.
Does the Diagnostics Menu appear?
Yes. See “Running the Diskette-Based Diagnostics” found later in this
chapter.
No. Proceed to step 6.
6. Insert another copy of the diagnostics diskette into the diskette drive,
and reboot the system.
Does the Diagnostics Menu appear?
Yes. See “Running the Diskette-Based Diagnostics” found later in this
chapter.
No. Proceed to the next section, “Internal Visual Inspection.”
Internal Visual Inspection
CAUTION: Before you proceed with the internal visual inspection described in
this section, ensure that the user has saved all open files and exited all open
application programs if possible.
A simple visual inspection of a system unit’s interior hardware can often lead to the
source of a problem, such as a loose expansion card, cable connector, or mounting screw.
When you perform the visual inspection, refer to “System Features” in Chapter 1 to locate
components in the inspection procedure.
To perform the internal visual inspection, follow these steps:
1. Turn off the system, including any attached peripherals, and disconnect
all the AC power cables from their power sources.
2. Remove the system unit cover.
2-4
Dell PowerEdge 2100/180 and 2100/200 Systems Service Manual
3. Verify that the microprocessor, DIMMs, and expansion cards, are fully
seated in their sockets or connectors.
WARNING: The microprocessor can get extremely hot. Be sure the chip
has had sufficient time to cool before you touch it.
While reseating the microprocessor, wear a wrist grounding strap or maintain contact with a metal surface on the chassis.
To reseat the microprocessor, remove it from its socket and reinstall it as
described in “Microprocessor/Heat Sink Assembly” in Chapter 4.
To reseat a DIMM, remove it from its socket and reinstall it as described in
“DIMMs” in Chapter 4.
If you need to reseat an expansion card, use a 1/4-inch nut driver to remove
the screw that secures the card-mounting bracket. Grasp the card by its top
corners, and carefully pull it out of its connector. Reinsert the card in its
connector, and carefully push it in until it is fully seated. Then reinstall the
card-mounting bracket’s retaining screw.
4. Verify that all jumpers are set correctly.
For information about these jumpers, see “System Board Jumpers” in Chapter 1.
5. Check all cable connectors inside the system unit to verify that they are
firmly attached to their appropriate connectors.
6. Reinstall the system unit cover.
7. Reconnect the system unit and any attached peripherals to their power
sources, and turn them on.
Does the problem appear to be resolved?
Yes. No further steps are necessary. Terminate the procedure.
No. Proceed to the next sections, “Eliminating Resource Conflicts,” “Running the Diskette-Based Diagnostics,” and to “Getting Help.”
Eliminating Resource Conflicts
Devices within the system unit may require dedicated memory spaces, interrupt
levels, or DMA channels, all of which must be allocated during installation of
the devices. Because a device may be installed at a different time, it is possible
that the same resource is assigned to two or more devices.
Resource conflicts can result in disorderly or erratic system operation or system
failure. If you suspect that resource conflicts might exist, check the system and
reassign the resources as necessary.
For additional information, see Chapter 5, “Using the EISA Configuration Utility” in the User’s Guide.
Basic Troubleshooting
2-5
Running the Diskette-Based Diagnostics
The diskette-based diagnostics (included with the system) contain tests that aid
in troubleshooting all major components of the computer system.
CAUTION: To prevent damage to the original diagnostics diskette, always use
a backup copy of the diagnostics diskette when servicing a user’s system. Dell recommends that users make several copies of this diskette to ensure that one is always
available.
To start the diagnostics, turn off the system unit, insert a diagnostics diskette
into drive A, and then turn on the system unit.
Starting the diagnostics causes the Dell logo screen to appear on the monitor
screen, followed by a message indicating that the diagnostics is loading. Before
the diagnostics loads, a program tests the portion of main memory (RAM)
required for loading the diagnostics. If a main memory error is detected, a message appears on the screen telling you which DIMM has failed.
If no errors are found in main memory, the diagnostics loads and the Diagnostics Menu appears. This menu lets you choose the following options or exit to
the Microsoft® MS-DOS® prompt:
•
RUN QUICK TESTS
•
•
RUN ALL TESTS
— Runs selected tests from all test groups to quickly
locate a failure or to indicate where further testing is needed to isolate a
failure
— Runs all tests for a thorough test of the system
RUN SPECIFIC TESTS
— Tests a particular area or subsystem
Getting Help
If none of the troubleshooting procedures in this chapter or the tests in the diskette-based diagnostics reveals the source of the problem or leads to the proper
troubleshooting steps for determining the source of the problem, call Dell for
technical assistance. For instructions, see the chapter titled “Getting Help” in
the Diagnostics and Troubleshooting Guide.

Chapter 3
Beep Codes and Error Messages
T
his chapter describes beep codes and system error messages that can occur
during POST or, in the case of some failures, during normal system operation.
The tables in this chapter list faults that can cause a beep code or system error
message to occur and the probable causes of the fault in each case.
If a faulty system does not emit beep codes or display system error messages to
indicate a failure, you should use the diskette-based diagnostics to run the
appropriate tests to help isolate the source of the problem. See “Running the
Diskette-Based Diagnostics” in Chapter 2.
POST Beep Codes
If the monitor cannot display error messages during the POST, the system may
emit a series of beeps that identifies the problem or that can help you identify a
faulty component or assembly. Table 3-1 lists the beep codes that may be generated during the POST. Most beep codes indicate a fatal error that prevents the
system from completing the boot routine until the indicated condition is
corrected.
When the system emits a beep code, record the code and then find it in
Table 3-1. If the table does not lead to the source of the problem, run the appropriate tests in the diskette-based diagnostics to assist in troubleshooting the
problem.

The heat sink and microprocessor are separate. Look at the bottom side of the
heat sink and peel the thermal-pad protective cover off before attaching the heat
sink to the microprocessor.
To install the replacement microprocessor/heat sink assembly, ensure that the microprocessor release lever is in its fully vertical position to allow the microprocessor pins
to easily slip into the socket. When the microprocessor/heat sink assembly is in place,
rotate the microprocessor release lever to its horizontal position.
NOTE: Pin 1 on the microprocessor is located on the corner with the largest
bevel. The pin-1 hole in the microprocessor socket is located on the corner
where the holes are in a diagonal pattern.
