Basic Troubleshooting
Dell™PowerEdge™500SCSystemsServiceManual
Overview
This section describes basic troubleshooting procedures that can help you diagnose a system problem. These procedures can often reveal the source of a
problem or indicate the correct starting point for servicing the system.
A brief explanation of how to load and start the system diagnostics can be found in "Running the System Diagnostics."
We recommend that you perform the following procedures in the order presented.
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. After the user describes the
problem, perform the following steps:
1. Ask the user to back up any data on the hard drive if the systems condition permits. See the documentation provided with the operating system or
applications software for 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.
If the user can not duplicate the problem, proceed to "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.
If the problem is a result of user error, instruct the user in the proper procedure or direct the user to the appropriate user documentation for the correct
procedure. If the user is performing the procedure correctly, proceed to "External Visual Inspection."
External Visual Inspection
Improperly set switches and controls and loose or improperly connected cables are the most likely source of problems for the system, monitor, or other
peripherals (such as a printer, keyboard, mouse, or other external equipment). A quick check of all the switches, controls, and cable connections can easily
solve these problems.
The external visual inspection consists of a quick inspection of the exterior of the system, the monitor (if attached), the keyboard (if attached), any peripherals,
and cables. While performing the visual inspection, make any necessary corrections. To perform the external visual inspection, perform the following steps.
1. Inspect the front panel LEDs for indication of component malfunction.
2. Turn off the system, the monitor (if attached), and all peripherals.
3. Verify that all power cables are properly connected to the system, the monitor and peripherals, and their power sources.
4. Inspect connections to any attached devices including network cables, keyboard, monitor, mouse (if used), or keyboard/video monitor/mouse (KVM)
switch (if used), as well as any devices attached to the parallel and serial ports.
5. Inspect all external monitor controls for any obvious damage or improper settings (if used). For proper settings of the video monitor controls, see the
documentation for the monitor.
6. Inspect the keyboard (if used) to ensure that no keys are sticking. If one or more keys are sticking, it may be necessary to replace the keyboard.
7. Inspect the exterior of the system, including all controls and indicators, and all user-accessible data storage devices for any signs of physical damage.
If the inspection reveals any problems, proceed to the appropriate procedure in "Removing and Replacing Parts." Proceed to "Observing the Boot
Routine," if the inspection does not reveal any problems.
Observing the Boot Routine
After you have performed an external visual inspection as described in "External Visual Inspection," you should boot the system and, while the boot routine is
running, observe the system for any indications of problems.
To perform the following procedure, you need a set of system diagnostics diskettes created from the Dell OpenManage Server Assistant CD.

Getting Help
Observing the Boot Routine
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 to complete all of these steps.
To observe problem indications during the boot routine, perform the following steps:
1. If the system is off, turn on all peripherals and the system.
2. Insert the bootable system diagnostics diskette into the diskette drive and reboot the system. If you haven't created your set of diagnostics diskettes,
see "Using the Dell OpenManage Server Assistant CD," in the User's Guide.
3. Check the power supply fan.
If the fan is not operating properly, troubleshoot the system power supply.
4. Watch the <Num Lock>, <Caps Lock>, and <Scroll Lock> indicators on the upper-right corner of the keyboard. After all three indicators flash
momentarily,andfollowingalongpause(approximately30seconds),the<NumLock>indicatorshouldlightupandremainon(unlesstheNum Lock
option is set to Off in the System Setup program).
If these indicators do not flash on and off within approximately 10 seconds after the boot routine starts, troubleshoot the system power supply. If the
troubleshooting procedure indicates that the system power supply is operational, troubleshoot the memory.
5. During the boot routine, observe the system for any of the following indications:
¡ Beep codes A beep code is a series of beeps that indicates an error condition. See "System Beep Codes."
¡ System error messages These messages can indicate problems or provide status information. If a system error message appears, see "System
Messages."
¡ Diskette-drive and hard 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 drive subsystem, as appropriate.
6. Observe the monitor screen for the Diagnostics menu.
If the Diagnostics menu appears, see "Running the System Diagnostics."
7. Insert another copy of the system diagnostics disketteintothediskettedrive,andrebootthesystem.
If the Diagnostics menu appears, see "Running the System Diagnostics." If the Diagnostics menu does not appear, proceed to "Internal Visual
Inspection."
Internal Visual Inspection
A simple visual inspection of a systems 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, see "System Features" to locate components referenced in the inspection procedure.
To perform the internal visual inspection, perform the following steps:
1. Turn off the system, including any attached peripherals, and disconnect all the power cables from electrical outlets.
2. Remove the system cover as described in "System Cover and Support Beam."
3. Verify that the chip sets, memory modules, expansion cards, and microprocessor and heat-sink assembly are fully seated in their sockets or connectors.
4. To ensure that the chip sets are fully seated in their sockets, press firmly on the top of each chip.
5. To remove and reseat a microprocessor and heat-sink assembly, perform the steps described in "Microprocessor."
6. To remove and reseat a memory module, perform the steps described in "Memory Modules."
7. If you need to remove and reseat an expansion card, remove the card as described in "Expansion Cards," and carefully reinsert the card in its connector
until fully seated.
8. Verify that all jumpers are set correctly.
For information about jumper settings, see "System Board Jumpers."
9. Check all cable connectors inside the system to verify that they are firmly attached to their appropriate connectors.
10. Replace the system cover and support beam.
11. Reconnectthesystemandanyattachedperipheralstotheirpowersources,andturnthemon.
If the problem persists, proceed to "Getting Help."
Running the System Diagnostics
NOTE: You can also run the system diagnostics from the utility partition by pressing <F10> during power-up.
NOTICE: 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.
CAUTION: Before beginning to work inside the system, disconnect the power supply from the power source and the power supply cables from the
power supply.
CAUTION: The microprocessor and heat-sink assembly can get extremely hot during system operations. Be sure that it has had sufficient time to cool
before touching it.
CAUTION: When handling the microprocessor and heat-sink assembly, take care to avoid sharp edges on the heat-sink.
Thesystemdiagnosticscontainteststhataidintroubleshootingallmajorcomponentsofthesystem.Thesediagnosticscanberunfromtheutilitypartitionor
from a set of diagnostics diskettes.
To create a set of diagnostics diskettes, see "Using the Dell OpenManage Server Assistant CD," in the User's Guide.
To start the system diagnostics, turn off the system, insert a bootable system diagnostics diskette into the diskette drive, and then turn on the system (you can
also activate the system diagnostics installed on the utility partition of your hard drive by pressing <F10> during power-up).
Starting the diagnostics causes the Dell logo to appear on the monitor, 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 RAM error is detected, a message telling you which memory
module has failed appears on the screen.
If no errors are found in RAM, the diagnostics loads and a Diagnostics menu appears. This menu lets you choose different options or exit the diagnostics.
See "Running the System Diagnostics" in the system Installation and Troubleshooting Guide for detailed information about the system diagnostics.

Warning Messages
A warning message alerts you to a possible problem and asks you to take corrective action before the system continues a task. For example, before you
format a diskette, a message might warn you that you might 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 y (yes) or n (no).
Diagnostics Messages
When you run a test group or subtest in the system diagnostics, an error message might result. These particular error messages are not covered in this
section. Record the message on a copy of the Diagnostics Checklist (located in "Getting Help" in the Installation and Troubleshooting Guide, and then follow the
instructions in that section for obtaining technical assistance.
Alert Log Messages From the System Management Server Agent
The optional system management software generates alert messages for your system. For example, the server agent generates messages that appear in the
SNMP trap log file. Alert messages consist of information, status, warning, and failure messages for drive, temperature, fan, and power conditions. More
information about alert messages is provided in the system management software documentation found on the Online Documentation CD that shipped with
your system.

Jumpers and Connectors
Dell™PowerEdge™500SCSystemsServiceManual
Overview
This section provides specific information about the jumpers on the system board. It also provides some basic information on jumpers and describes the
connectors and sockets on the various boards in the system.
Jumpers A General Explanation
Jumpers provide a convenient and reversible way of reconfiguring the circuitry on a printed circuit board. When installing replacement parts or reconfiguring
the system, you may need to change jumper settings on the system board. You may also need to change jumper settings on expansion cards or drives.
Jumpers
Jumpers are small blocks on a circuit board with two or more pins emerging from them. 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.
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.
System Board Jumpers
Figure 1 shows the location of the configuration jumpers on the system board. Table 1 lists the function of these jumpers.

Disabling a Forgotten Password
The computer's software security features include a supervisor password and a user password, which are discussed in detail in "Using the System Setup
Program" of the 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 supervisor password or user password, perform the following steps.
1. Turn off the system, including any attached peripherals, and disconnect the power cord from its power source.
2. Remove the system cover.
3. See Figure 1 for the location of the password jumper (labeled PASSWORD) on the system board.
4. Remove the jumper plug from the PASSWORD jumper.
5. Replace the system cover and then reconnect the computer to an electrical outlet and turn it on.
The existing passwords are not disabled (erased) until the system boots with the PASSWORD jumper plug removed. However, before you assign a new
system and/or user password, you must install the jumper plug.
6. Repeat step 1.
7. Install the jumper plug on the PASSWORD jumper.
8. Replace the system cover and then reconnect the computer and peripherals to their electrical outlets and turn them on.
9. Assign a new system and/or user password.
To assign a new system and/or user password, see "Using the System Setup Program".
