Additional Safety Precautions To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment, observe the following precautions.

General Precautions Observe the following general precautions for using and working with your system:

Observe and follow service markings. Do not service any Dell product except as explained in your Dell system documentation. Opening or removing covers that are marked with the triangular symbol with a lightning bolt may expose you to electrical shock. Components inside these compartments should be serviced only by a Dell authorized service technician.

If any of the following conditions occur, unplug the product from the electrical outlet and replace the part or contact your Dell authorized service provider:

The power cable, extension cord, or plug is damaged.

An object has fallen into the product.

The product has been exposed to water.

The product has been dropped or damaged.

vi

The product does not operate correctly when you follow the operating instructions.

Keep your system components away from radiators and heat sources. Also, do not block cooling vents.

Do not spill food or liquids on your system components, and never operate the product in a wet environment. If the computer gets wet, see the appropriate sec- tion in your troubleshooting guide or contact a Dell-authorized service provider.

Do not push any objects into the openings of your system components. Doing so can cause fire or electric shock by shorting out interior components.

Use the product only with Dell products or other Dell-approved equipment.

Allow the product to cool before removing covers or touching internal components.

Use the correct external power source. Operate the product only from the type of power source indicated on the electrical ratings label. If you are not sure of the type of power source required, consult your Dell service provider or local power company.

To help avoid damaging your system components, be sure the voltage selection switch (if provided) on the power supply is set to match the power available at your location:

115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries such as South Korea and Taiwan

100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan

230 V/50 Hz in most of Europe, the Middle East, and the Far East

Also be sure that your monitor and attached peripherals are electrically rated to operate with the power available in your location.

Use only approved power cable(s). If you have not been provided with a power cable for your computer or storage system or for any AC-powered option intended for your system, purchase a power cable that is approved for use in your country. The power cable must be rated for the product and for the voltage and current marked on the products electrical ratings label. The voltage and current rating of the cable should be greater than the ratings marked on the product.

To help prevent electric shock, plug the system components and peripheral power cables into properly grounded electrical outlets. These cables are equipped with three-prong plugs to help ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use an extension cord, use a three-wire cord with properly grounded plugs.

Observe extension cord and power strip ratings. Make sure that the total ampere rating of all products plugged into the extension cord or power strip does not exceed 80 percent of the extension cord or power strip ampere ratings limit.

Do not use appliance/voltage converters or kits sold for appliances with your Dell product.

vii

To help protect your system components from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or uninter- ruptible power supply (UPS).

Position cables and power cords carefully; route cables and the power cord and plug so that they cannot be stepped on or tripped over. Be sure that nothing rests on your system components cables or power cord.

Do not modify power cables or plugs. Consult a licensed electrician or your power company for site modifications. Always follow your local/national wiring rules.

To help avoid possible damage to the system board, wait 5 seconds after turning off the system before removing a component from the system board or discon- necting a peripheral device from the computer.

Handle batteries carefully. Do not disassemble, crush, puncture, short external contacts, dispose of in fire or water, or expose batteries to temperatures higher than 60 degrees Celsius (140 degrees Fahrenheit). Do not attempt to open or ser- vice batteries; replace batteries only with batteries designated for the product.

Turn down the volume before using headphones or other audio devices.

Precautions for Server and Storage Systems Follow the additional safety guidelines for your system:

Unless your installation and/or troubleshooting documentation specifically allows it, do not remove enclosure covers, attempt to override the safety interlocks, or access any components inside the system. Depending on your system, installa- tion and repairs may be done only by individuals who are qualified to service your computer or storage system equipment and trained to deal with products capa- ble of producing hazardous energy levels.

When connecting or disconnecting power to hot-pluggable power supplies, if offered with your Dell product, observe the following guidelines:

Install the power supply before connecting the power cable to the power supply.

Unplug the power cable before removing the power supply.

If the system has multiple sources of power, disconnect power from the sys- tem by unplugging all power cables from the power supplies.

Move products with care; ensure that all casters and/or stabilizers are firmly con- nected to the computer or storage system. Avoid sudden stops and uneven surfaces.

Precautions for Rack-Mountable Products Observe the following precautions for rack stability and safety. Also refer to the rack installation documentation accompanying the system and the rack for specific warn- ing and/or caution statements and procedures.

viii

WARNING: Installing Dell system components in a Dell rack without the front

and side stabilizers installed could cause the rack to tip over, potentially result-

ing in bodily injury under certain circumstances. Therefore, always install the

stabilizers before installing components in the rack.

After installing system components in a rack, never pull more than one compo-

nent out of the rack on its slide assemblies at one time. The weight of more

than one extended component could cause the rack to tip over and injure

someone.

NOTE: Dells server and storage systems are certified as components for use in Dells rack cabinet using the Dell customer rack kit. The final installation of Dell systems and rack kits in any other brand of rack cabinet has not been approved by any safety agen- cies. It is the customers responsibility to have the final combination of Dell systems and rack kits for use in other brands of rack cabinets evaluated for suitability by a certi- fied safety agency.

System rack kits are intended to be installed in a Dell rack by trained service tech- nicians. If you install the kit in any other rack, be sure that the rack meets the specifications of a Dell rack.

Do not move large racks by yourself. Due to the height and weight of the rack, Dell recommends a minimum of two people to accomplish this task.

Before working on the rack, make sure that the stabilizers are secure to the rack, extend to the floor, and that the full weight of the rack rests on the floor. Install front and side stabilizers on a single rack or front stabilizers for joined multiple racks before working on the rack.

Always load the rack from the bottom up, and load the heaviest item in the rack first.

Make sure that the rack is level and stable before extending a component from the rack.

Extend only one component at a time from the rack.

Use caution when pressing the component rail release latches and sliding a com- ponent into or out of a rack; the slide rails can pinch your fingers.

After a component is inserted into the rack, carefully extend the rail into a locking position, and then slide the component into the rack.

Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not exceed 80 percent of the branch circuit rating.

Ensure that proper airflow is provided to components in the rack.

Do not step on or stand on any system/component when servicing other systems/components in a rack.

ix

Precautions for Products With Modems, Telecommunications, or Local Area Network Options Observe the following guidelines when working with options:

Do not connect or use a modem or telephone during a lightning storm. There may be a risk of electrical shock from lightning.

Never connect or use a modem or telephone in a wet environment.

Do not plug a modem or telephone cable into the network interface controller (NIC) receptacle.

Disconnect the modem cable before opening a product enclosure, touching or installing internal components, or touching an uninsulated modem cable or jack.

Do not use a telephone line to report a gas leak while you are in the vicinity of the leak.

Precautions for Products With Laser Devices Observe the following precautions for laser devices:

Do not open any panels, operate controls, make adjustments, or perform proce- dures on a laser device other than those specified in the products documentation.

Only authorized service technicians should repair laser devices.

When Working Inside Your Computer Before you remove the computer covers, perform the following steps in the sequence indicated.

NOTICE: Some Dell systems can be serviced only by trained service technicians

because of high voltages and energy hazards. Do not attempt to service the

computer system yourself, except as explained in this guide and elsewhere in

Dell documentation. Always follow installation and service instructions closely.

NOTICE: To help avoid possible damage to the system board, wait 5 seconds

after turning off the system before removing a component from the system

board or disconnecting a peripheral device from the computer.

1. Turn off your computer and any peripherals.

2. Ground yourself by touching an unpainted metal surface on the chassis, such as the metal around the card-slot openings at the back of the computer, before touching anything inside your computer.

While you work, periodically touch an unpainted metal surface on the computer chassis to dissipate any static electricity that might harm internal components.

x

3. Disconnect your computer and peripherals from their power sources. Also, dis- connect any telephone or telecommunication lines from the computer.

Doing so reduces the potential for personal injury or shock.

In addition, take note of these safety guidelines when appropriate:

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 dis- connecting 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 bend- ing any connector pins. Also, before you connect a cable, make sure that both connectors are correctly oriented and aligned.

Handle components and cards with care. Dont touch the components or con- tacts 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.

CAUTION: There is a danger of a new battery exploding if it is incor- rectly installed. Replace the battery only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to the manufacturers instructions.

Protecting Against Electrostatic Discharge Static electricity can harm delicate components inside your computer. To prevent static damage, discharge static electricity from your body before you touch any of your computers 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.

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 from the antistatic packing material until you are ready to install the component in your 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 notice may appear throughout this document to remind you of these precautions:

NOTICE: See "Protecting Against Electrostatic Discharge" in the safety

instructions.

xi

Ergonomic Computing Habits CAUTION: Improper or prolonged keyboard use may result in injury.

CAUTION: Viewing the monitor screen for extended periods of time may result

in eye strain.

For comfort and efficiency, observe the following ergonomic guidelines when you set up and use your computer system:

Position your system so that the monitor and keyboard are directly in front of you as you work. Special shelves are available (from Dell and other sources) to help you correctly position your keyboard.

Set the monitor at a comfortable viewing distance (usually 510 to 610 millimeters [20 to 24 inches] from your eyes).

Make sure that the monitor screen is at eye level or slightly lower when you sit in front of the monitor.

Adjust the tilt of the monitor, its contrast and brightness settings, and the lighting around you (such as overhead lights, desk lamps, and the curtains or blinds on nearby windows) to minimize reflections and glare on the monitor screen.

Use a chair that provides good lower back support.

Keep your forearms horizontal with your wrists in a neutral, comfortable position while you use the keyboard or mouse.

Always leave space to rest your hands while you use the keyboard or mouse.

Let your upper arms hang naturally at your sides.

Sit erect, with your feet resting on the floor and your thighs level.

When sitting, make sure the weight of your legs is on your feet and not on the front of your chair seat. Adjust your chairs height or use a footrest, if necessary, to maintain proper posture.

Vary your work activities. Try to organize your work so that you do not have to type for extended periods of time. When you stop typing, try to do things that use both hands.

Introduction

Dell PowerEdge 2400 computer systems are high-speed servers that offer signifi- cant service and upgrade features. These systems include the following service features to make troubleshooting and repair easy and effective:

Dell Diagnostics, which checks for hardware problems (if the system can boot)

Embedded server management hardware, which monitors temperatures and voltages throughout the system and notifies you if the system overheats, if a sys- tem cooling fan malfunctions, or a power supply fails

Optional redundant, hot-plug power supplies

The Dell PowerEdge 2400 system chassis simplifies removing and replacing com- puter components. You can perform processor and memory upgrades 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 following upgrade options are offered for the Dell PowerEdge 2400 systems:

Additional microprocessors

Additional memory

An integrated redundant arrays of independent disks (RAID) controller

A 1 x 6 or 1 x 4 SCSI backplane

A variety of expansion-card options

Dual redundant, hot-plug power supplies

A Dell OpenManage Remote Assistant Card 2 (DRAC 2) for advanced server management

Checking the Basics

If your Dell PowerEdge 2400 system is not working as expected, begin trouble- shooting using the procedures in this section. This section guides you through some initial checks and procedures that can solve basic computer problems. It can also direct you to the appropriate section for detailed troubleshooting information and pro- cedures to solve more complex problems.

NOTE: When you see the question "Is the problem resolved?" in a troubleshooting procedure, perform the operation that caused the problem.

Backing Up Files If the system is behaving erratically, back up the files on the hard-disk drives immedi- ately. See the documentation that came with the operating system for instructions on how to back up the files.

Basic Checks The following procedure leads you through the checks necessary to solve some basic computer problems:

1. Was an alert message issued by the Dell OpenManage Hardware Instrumenta- tion Package (HIP) server management application program?

Yes. Go to "Alert Log Messages From the Dell OpenManage HIP Application Pro- gram" in Chapter 3, "Messages and Codes."

No. Go to step 2.

2. Is the computer wet or damaged?

Yes. Go to Chapter 7, "Checking Inside the Computer."

No. Go to step 3.

support.dell.com Checking the Basics 2-1

3. Perform the steps in the next section, "Checking Connections and Switches."

Is the problem resolved?

Yes. The power to the computer system was faulty, or the connections to the computer system were loose. You have fixed the problem.

No. Go to step 4.

4. Follow the procedures described in "Look and Listen," found later in this chapter.

Did the system complete the boot routine?

Yes. Go to step 5.

No. A serious malfunction may have occurred. Go to Chapter 11, "Getting Help."

5. Did you receive a system message or beep code?

Yes. Go to "System Messages" in Chapter 3, Messages and Codes.

No. Go to step 6.

6. Verify the settings in the System Setup program. (See Chapter 4, Using the Sys- tem Setup Program, in your Users Guide.

Is the problem resolved?

Yes. The system configuration information was incorrect. You have fixed the problem.

No. Go to step 7.

7. Run the Dell Diagnostics. (See Chapter 5, Running the Dell Diagnostics.)

Checking Connections and Switches Improperly set switches and controls and loose or improperly connected cables are the most likely source of problems for the computer, 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.

Figure 2-1 shows the back-panel connections on the computer. Figure 2-2 shows the front-panel controls and indicators on the computer.

The System Setup Program You can easily correct certain system problems by verifying the correct settings in the System Setup program. When you boot the system, the system checks the system configuration information and compares it with the current hardware configuration. If the system hardware configuration does not match the information recorded by the System Setup program, an error message may appear on the screen.

This problem can happen if you changed the system's hardware configuration and for- got to run the System Setup program. To correct this problem, enter the System Setup program, correct the corresponding System Setup setting, and reboot the sys- tem. See Chapter 4, "Using the System Setup Program," in the User's Guide for detailed instructions on using the System Setup program.

The hard-disk drive activity indicators

The hard-disk drive activity indicators should quickly flash on and off when you access data on the hard-disk drives. On a system running the Microsoft Windows NT oper- ating system, you can test the drive by opening Windows Explorer and clicking the icon for drive C. If the hard-disk drive access indicator does not come on, see "Trouble- shooting SCSI Hard-Disk Drives" in Chapter 7, "Checking Inside the Computer."

A series of beeps See "System Beep Codes" in Chapter 3, "Messages and Codes."

An unfamiliar constant scraping or grinding sound when you access a drive

Make sure the sound is not caused by the application program you are running. The sound could be caused by a hardware mal- function. See Chapter 11, "Getting Help," for instructions on obtaining technical assis- tance from Dell.

System Beep Codes When an error that cannot be reported on the monitor occurs during a boot routine, 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 technical support representative if you need to call for technical assistance.

NOTE: If the system boots without a keyboard, mouse, or monitor attached, the com- puter will not issue beep codes related to these peripheerals.

When a beep code is emitted, record it on a copy of the Diagnostics Checklist in Chapter 11, "Getting Help," and then look it up in Table 3-2. If you are unable to resolve the problem by looking up the meaning of the beep code, use the Dell Diagnostics to identify a more serious cause. If you are still unable to resolve the problem, see Chapter 11, "Getting Help," for instructions on obtaining technical assistance.

SCSI Hard-Disk Drive Indicator Codes If a redundant arrays of independent disks (RAID) controller such as the optional PowerEdge Expandable RAID Controller (PERC) 2/Si controller is installed in the sys- tem, three light-emitting diode (LED) indicators on each of the hard-disk drive carriers provide information on the status of the SCSI hard-disk drives (see Figure 3-1). The SCSI backplane firmware controls the drive online and drive failure indicators.

Figure 3-1. Hard-Disk Drive Indicators

1 Drive online indicator

2 Drive activity indicator

3 Drive failure indicator

3-16 Dell PowerEdge 2400 Systems Installation and Troubleshooting Guide

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, fol- lowed by the "drive ready for insertion or removal" pattern. After the replacement drive is installed, the "drive being prepared for operation" pattern appears, followed by the "drive online" pattern.

NOTE: If you do not have a RAID controller installed, you will see only the "drive online" and "drive bay empty" indicator patterns.

Finding Software Solutions

Because most computer systems have several application programs installed in addi- tion 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 system problem is caused by software by running the system boardtests in the Dell Diagnostics (see Chapter 5, Running the Dell Diagnostics). If all tests in the test group are completed successfully, the problem is most likely caused by software.

This section provides some general guidelines for analyzing software problems. For detailed troubleshooting information on a particular program, see the documentation that accompanied the software or consult the support service for the software.

Installing and Configuring Software Use virus-scanning software to check newly acquired application programs and files for viruses before you install the programs on the computer's hard-disk drive. Viruses can quickly use all available system memory, damage and/or destroy data stored on the hard-disk drive, and permanently affect the performance of the programs they infect. Several commercial virus-scanning programs are available for purchase.

Before you install a program, 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.

The software installation routine assists you 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. Always read the installation instructions before running a program's installation routine.

support.dell.com Finding Software Solutions 4-1

When you run the installation routine, be prepared to respond to prompts for informa- tion about how the computer's operating system is configured, what type of computer you have, and what peripheral devices are connected to the computer.

Using Software The following subsections discuss errors that can occur as a result of software opera- tion or configuration.

Error Messages Error messages can be produced by an application program, the operating system, or the computer. Chapter 3, "Messages and Codes," provides information about the error messages that are generated by the computer. If you receive an error message that is not listed in Chapter 3, "Messages and Codes," check the operating system or applica- tion program documentation.

Input Errors If you press a specific key or set of keys at the wrong time, a program may give you unexpected results. See the documentation that came with the application program to make sure that the values or characters you are entering are valid.

Make sure that the operating environment is set up to accommodate the programs you use. Keep in mind that whenever you change the parameters of the computer's operating environment, you may affect the successful operation of the programs. Sometimes, after modifying the operating environment, you may need to reinstall a program that no longer runs properly.

Program Conflicts Some programs may leave portions of their setup information behind, even though you have exited from them. As a result, other programs cannot run. Rebooting the system can confirm whether these programs are the cause of the problem.

Device drivers, which are programs that use specialized subroutines, can cause prob- lems 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 alternate method of running that particular programby creating a start-up file made especially for that program, for example. Call the support service for the software you are using to help you with this problem.

Avoiding Interrupt Assignment Conflicts Problems can arise if two devices attempt to use the same interrupt request (IRQ) line. To avoid this type of conflict, check the documentation for the IRQ line's default for each installed expansion card. Then consult Table 4-1 to configure the card for one of the available IRQ lines.

Running the Dell Diagnostics

Unlike many diagnostic programs, the Dell Diagnostics helps you check the com- puter's hardware without any additional equipment and without destroying any data. By using the diagnostics, you can have confidence in the computer system's opera- tion. If you find a problem that you cannot solve by yourself, the diagnostic tests can provide you with important information you will need when talking to Dell's technical assistance representative.

NOTICE: Use the Dell Diagnostics to test only Dell computer systems. If you use

this program with other computers, incorrect computer responses or error mes-

sages may result.

Features of the Dell Diagnostics The Dell Diagnostics provides a series of menus and options from which you choose particular device groups or devices. You can also control the sequence in which the tests are run. The diagnostic menus 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 is repeated

The ability to display or print 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

Help messages that briefly describe each test and its parameters

Status messages that inform you whether device group or device tests are com- pleted successfully

Error messages that appear if any problems are detected

When to Use the Dell Diagnostics Whenever a major component or device in the computer system does not function properly, you may have a component failure. As long as the microprocessor and the input and output components of the computer system (the monitor, keyboard, and diskette drive) are working, you can use the Dell Diagnostics. If you know what

support.dell.com Checking Inside the Computer 7-7

The system board holds the computer's control circuitry and other electronic compo- nents. Some hardware options are installed directly on the system board. The external drive bays provide space for up to three half-height 5.25-inch drives, typically CD-ROM drives or tape drives. The diskette drive bay holds a 3.5-inch diskette drive. The hard-disk drive bays provide space for up to four 1.6-inch or six 1-inch SCSI hard- disk drives. These hard-disk drives are connected to a SCSI host adapter on the system board or on an expansion card, via the SCSI backplane board.

When you look inside the computer, note the power cables leading from the power supply(s). The power cables supply power to the system board, SCSI backplane board, externally accessible drives, and any expansion cards that connect to external peripherals.

For non-SCSI drives such as the diskette drive, an interface cable connects each drive to an interface connector on the system board or on an expansion card. For SCSI devices, 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 expan- sion card. (For more information, see Chapter 9, "Installing Drives in the External Bays," and Chapter 10, "Installing Hard-Disk Drives.")

During an installation or troubleshooting procedure, you may be required to change a jumper or switch setting. For information on the system board jumpers, see Appendix A, "Jumpers, Switches, and Connectors."

Responding to a Dell OpenManage Hardware Instrumentation Package Alert Message The Dell OpenManage Hardware Instrumentation Package (HIP) server management application program monitors critical system voltages and temperatures, the system cooling fans, and the status of the SCSI hard-disk drives in the computer. The applica- tion program generates alert messages that appear in the Simple Network Management Protocol (SNMP) trap log file. More information about the Alert Log window and options is provided in the Dell OpenManage HIP online help and the HP OpenView User's Guide.

Troubleshooting a Wet Computer Liquid spills, splashes, and excessive humidity can cause damage to the system. If an external device (such as a printer or an external drive) gets wet, contact the device manufacturer for instructions. If the computer gets wet, perform the following steps:

1. Turn off the system, including any attached peripherals, and disconnect the sys- tem from the electrical outlet.

8. If you are relocating or removing an ISA expansion card, run the Resource Config- uration Utility, and delete the expansion card from the configuration information. See Chapter 5, "Using the Resource Configuration Utility," in the User's Guide for instructions.

support.dell.com Installing System Board Options 8-7

Adding Memory The four dual in-line memory module (DIMM) sockets on the system board can accommodate 64 megabytes (MB) to 2 gigabyte (GB) of registered synchronous dynamic random-access memory (SDRAM). The DIMM sockets are located near the back edge of the system board (see Figure 8-1).

Memory Upgrade Kits The system is upgradeable to 2 GB by installing four 512-MB DIMMs. You can pur- chase memory upgrade kits of 64-, 128-, 256-, and 512-MB registered DIMMs from Dell.

NOTE: The DIMMs must be rated to run at 133 MHz or faster.

DIMM Installation Guidelines Starting with the socket nearest to the system board's back edge, the DIMM sockets are labeled "DIMM_A" through "DIMM_D" (see Figure 8-4). When you install 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 capac- ity, beginning with the highest-capacity DIMM in socket DIMM_A.

You do not need to install DIMMs in pairs.

Table 8-1 illustrates several sample memory configurations based on these guidelines.

Performing a Memory Upgrade To perform a memory upgrade to the system board, perform the following steps.

NOTICE: See "Protecting Against Electrostatic Discharge" in the safety instructions.

1. Remove the right-side computer cover.

2. Remove the cooling shroud.

3. Locate the DIMM sockets in which you will install or replace DIMMs. Figure 8-1 shows the relative location of the DIMM sockets on the system board. Figure 8-4 shows the labeling of the DIMMs sockets.

4. Install or replace the DIMMs as necessary to reach the desired memory total.

5. Replace the cooling shroud and computer cover, reconnect the system to the electrical outlet, and turn on the system.

After the system completes the power-on self test (POST) routin, it runs a mem- ory test. The system detects that the new memory does not match the system configuration information, which is stored in nonvolatile RAM (NVRAM). The monitor displays an error message that ends with the following words:

Replacing the Battery The system battery maintains system configuration, date, and time information in a special section of memory when you turn off the system. The operating life of the bat- tery ranges from 2 to 5 years, depending on how you use the system (for example, if you keep the system on most of the time, the battery gets little use and thus lasts longer). You may need to replace the battery if an incorrect time or date is displayed during the boot routine along with the following or similar message:

Time-of-day not set -- please run SETUP program Strike the F1 key to continue, F2 to run the setup utility

or

System CMOS checksum bad -- Run SETUP 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 pro- gram, 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 defec- tive battery.

You can operate the system without a battery; however, the system configuration information maintained by the battery in NVRAM is erased each time you shut down the computer. Therefore, you must reenter the system configuration information and reset the options each time the system boots until you replace the battery.

The battery is a 3.0-volt (V), coin-cell CR2032-type battery. To remove the battery, per- form the following steps.

Installing Drives in the External Bays

The external drive bays at the front of a Dell PowerEdge 2400 system hold up to three user-accessible, half-height 5.25-inch devices (typically CD-ROM or tape drives). A small computer system interface (SCSI) CD-ROM drive is standard in the first exter- nal drive bay, while two additional devices of your choice can be installed in the next two external drive bays. External SCSI devices are connected to the Ultra/Narrow SCSI controller on the system board. A fourth drive bay accommodates a standard 3.5-inch diskette drive, which is controlled by the diskette drive controller on the sys- tem board. See Figure 9-1 for a general view of the various drives, connector cables, and power cables in the external drive bays.

9-2 Dell PowerEdge 2400 Systems Installation and Troubleshooting Guide

Before You Begin This section describes how to install the following options:

Drives that use the computer's integrated diskette drive controller

Drives that use the computer's integrated Ultra/Narrow SCSI controller

Tape drives that use a controller card

NOTE: If you are installing a SCSI hard-disk drive, see Chapter 10, "Installing Hard-Disk Drives."

To remove or install drives in the external bays, you must remove the computer covers.

WARNING: Before you perform the procedures in this section, you must turn off the computer and disconnect it from its AC power source. For more information, see "Safety FirstFor You and Your Computer" in Chapter 7.

Removing and Replacing Front-Panel Inserts To protect the inside of the computer from foreign particles, a plastic insert covers each empty external drive bay. Additionally, each empty external drive bay is covered by a metal insert to maintain the necessary electromagnetic interference (EMI) shield- ing for the chassis. Before you install a drive in an empty bay, you must first remove the plastic and metal inserts. Whenever you remove a drive, be sure to replace the metal insert on the chassis and then replace the plastic insert in the front bezel to cover the empty bay.

Removing a Plastic Insert To remove the plastic insert for a drive bay that you intend to use, perform the follow- ing steps:

1. Remove the front bezel.

2. Facing the inside of the front bezel, press against the center of the insert with your thumbs until the insert bows sufficiently to loosen the tabs on the sides of the insert.

3. Pull the insert out of the bezel.

Removing a Metal Insert To remove the metal insert from a drive bay, perform the following steps:

1. Remove the front bezel.

2. Use your thumb to press in the tab on the right edge of the metal insert to release the insert.

support.dell.com Installing Drives in the External Bays 9-3

3. Pivot the insert away from the chassis and disengage the tab on the insert's left edge.

Connecting the Drive This section describes the interface cables and power cables used with the drives in your system.

Interface Cables Most interface connectors are keyed for correct insertion; that is, a notch or a raised tab on one connector matches a tab or a notch on the other connector. Keying ensures that the pin-1 wire in the cable goes to the pin-1 ends of the connectors on both ends.

When you disconnect an interface cable, take care to grasp the cable connector, rather than the cable itself, to avoid stress on the cable.

DC Power Cables Each drive in the external drive bays must connect to a 4-wire DC power cable from the system power supply. The connectors on these cables are labeled "P3," "P4," "P5," and "P6." Connectors P3, P4, and P5 are used for 5.25-inch devices; connector P6 is used for the 3.5-inch diskette drive.

SCSI Configuration Information Although SCSI devices are installed essentially the same way as other devices, their configuration requirements are different. To configure SCSI devices installed in the external bays, follow the guidelines in the following subsections.

SCSI ID Numbers Each device attached to the Ultra/Narrow SCSI host adapter must have a unique SCSI ID number from 0 to 7.

When SCSI devices are shipped from Dell, the default SCSI ID numbers are assigned as follows:

The integrated 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.

9-4 Dell PowerEdge 2400 Systems Installation and Troubleshooting Guide

Device Termination SCSI logic requires that the two devices at opposite ends of the SCSI chain be termi- nated and that all devices in between be unterminated. The SCSI cable included in your system has an active terminator installed at the end of the cable. Therefore, you should disable the termination on all SCSI devices you attach to this cable.

Installing a SCSI Device To install a SCSI device that uses the integrated Ultra/Narrow SCSI controller, perform the following steps:

1. Prepare the drive for installation.

NOTICE: See "Protecting Against Electrostatic Discharge" in the safety instructions.

Ground yourself by touching an unpainted metal surface on the back of the com- puter, unpack the drive, and compare the jumper and switch settings with those in the drive documentation. (See "SCSI Configuration Information" in Chapter 9, "Installing Drives in the External Bays," for information on setting the drive's SCSI ID number and enabling termination [if required].) Change any settings necessary for this system's configuration.

If the drive does not already have drive rails attached, attach a drive rail to each side of the drive and 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 front bezel and right-side computer cover.

3. 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.

4. Remove the metal insert from the drive bay.

5. 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.

6. Plug the DC power cable connector into the 4-pin power input connector on the back of the drive.

7. Select the connector on the Ultra/Narrow SCSI cable that most easily reaches the new SCSI device, and press the interface cable connector firmly onto the drive's interface connector.

8. If you moved other drives in step 3, snap them back into place.

9. Check all cable connections that may have been loosened during this procedure. Arrange cables so that they will not catch on the computer covers or block the air- flow of the fans or cooling vents.

support.dell.com Installing Drives in the External Bays 9-5

10. If a front-panel insert on the front bezel blocks the bay in which you installed the drive, remove the insert.

11. Replace the front bezel and right-side computer cover.

12. Reconnect the computer and peripherals to their AC power sources, and turn them on.

13. Test the SCSI devices.

14. To test a SCSI tape drive, refer to the documentation for the tape drive software to perform a tape drive backup and verification test.

Installing a Tape Drive That Uses a Controller Card Tape drives that require their own separate controller cards are shipped with the con- troller card and an interface cable.

To install the drive in an external drive bay, perform the following steps:

1. Configure the controller card if necessary.

Refer to the documentation that came with the tape drive and the card. If the card incorporates jumpers or switches that must be set to work with the system, verify or change the settings as necessary.

NOTICE: See "Protecting Against Electrostatic Discharge" in the safety instructions.

2. Remove the right-side computer cover.

3. If other installed drives are in the way, disengage them by pressing in on the plas- tic drive rails at the front of the bay, and slide them slightly toward the front of the chassis.

4. Remove the metal insert from the drive bay.

5. 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.

6. Determine which DC power cable connector to use, and then plug the DC power cable connector into the 4-pin power input connector on the back of the drive.

7. Install the controller card in an expansion slot.

8. Attach the interface cable that came with the drive kit to the interface connector on the back of the drive.

9. Connect the interface cable to the controller connector on the controller card. Refer to the controller card's documentation to identify the controller connector on the card.

This section describes how to install and configure small computer system interface (SCSI) hard-disk drives in the computer's internal hard-disk drive bays. Instructions are also included for upgrading the system by installing a different SCSI backplane board or a Dell PowerEdge Expandable RAID Controller (PERC) host adapter card.

WARNING: Before you install a new backplane board or host adapter card, you must turn off the computer and disconnect it from its AC power source. For more information, see "Safety FirstFor You and Your Computer" in Chapter 7.

The hard-disk drive bays provide space for up to four 1.6-inch or six 1-inch hard-disk drives. (See Chapter 9, "Installing Drives in the External Bays," for information on installing SCSI CD-ROM drives and SCSI tape drives in the external drive bays.)

Figure 10-1 illustrates the hard-disk drive bays, the hot-plug SCSI backplane board, and the Ultra2/low voltage differential (LVD) SCSI cable. The Ultra2/LVD SCSI cable has two connectors:

The connector at one end attaches to the Ultra2/LVD SCSI host adapter connec- tor labeled "SCSI1" on the system board or to an optional SCSI host adapter card such as the Dell PERC 2.

The connector at the other end of the cable attaches to the connector labeled "SCSIA" on the SCSI backplane board.

Dell recommends that you use only drives that Dell has tested and approved for use with the SCSI backplane board.

SCSI Hard-Disk Drive Configuration The SCSI drives must be configured as follows:

Disable termination on the drives. The SCSI backplane board provides termination for the SCSI bus.

Set the SCSI ID on all drives to 0. All SCSI ID numbers for the drives are set by the SCSI backplane board (the rightmost drive is set to SCSI ID 0).

Configure the drives so that the drive motor waits for a Start Unit command from the SCSI host adapter before spinning.

Partitioning and Formatting SCSI Hard-Disk Drives You may need to use different programs than those provided with the operating sys- tem to partition and format SCSI hard-disk drives. See Chapter 3, "Installing and Configuring SCSI Drivers," in the User's Guide for information and instructions.

NOTICE: Do not turn off or reboot your system while the drive is being for- matted. Turning off or rebooting your system while the drive is being formatted can cause a drive failure.

When you format a high-capacity SCSI hard-disk drive, be sure to allow enough time for the formatting to complete. Long formatting times for these drives are normal. A 9-gigabyte (GB) hard-disk drive, for example, can take up to 2.5 hours to format.

Installing and Removing SCSI Hard-Disk Drives SCSI hard-disk drives are supplied by Dell in special drive carriers that fit in the hard- disk drive bays.

Installing a SCSI Hard-Disk Drive To install a SCSI hard-disk drive, perform the following steps.

NOTICE: Hot-plug drive installation is not supported for systems without an integrated RAID controller or Dell PERC 2 host adapter card.

1. If the system does not have a RAID controller installed, shut down the system.

2. Unloc and open the front bezel.

support.dell.com Installing Hard-Disk Drives 10-3

3. For systems with RAID controllers, power down the hard-disk drive bay. If a hard- disk drive is currently installed in the bay, wait until all three SCSI hard-disk drive indicators on the hard-disk drive carrier handle are turned off before proceeding.

4. Open the drive carrier handle and slide the carrier toward you until it is free of the drive bay.

5. Open the handle on the new hard-disk drive carrier.

Figure 10-2. Installing a SCSI Hard-Disk Drive Carrier

6. Align the edge of the carrier with the notches in the hard-disk drive bay keys and insert the carrier into the drive bay (see Figure 2).

7. Close the drive carrier handle to lock the drive in place.

8. Close and lock the front bezel.

9. For systems with RAID controllers, restore power to the drive bay.

10. If the hard-disk drive is a new drive, run the Dell Diagnostics to test the new drive.

Removing a SCSI Hard-Disk Drive To remove a SCSI hard-disk drive, perform the following steps.

NOTICE: Hot-plug drive removal is not supported for systems without a PERC 2/Si integrated RAID controller or PERC 2 host adapter card.

1. If the system does not have a RAID controller installed, shut down the system.

2. Open the front bezel.

3. For systems with RAID controllers, power down the hard-disk drive bay and wait until the SCSI hard-disk drive indicator codes on the drive carrier signal that the drive may be removed safely.

When all indicators are turned off, the drive is ready for removal.

4. Open the drive carrier handle to release the carrier.

5. Slide the carrier toward you until it is free of the drive bay.

6. Close the front bezel.

Installing a Dell PowerEdge Expandable RAID Controller Host Adapter Card Follow these general guidelines when you install a Dell host adapter card. For specific instructions, refer to the documentation supplied with the PERC host adapter card.

WARNING: Before you install the host adapter card, you must turn off the computer and disconnect it from the electrical outlet. For more information, see "Safety FirstFor You and Your Computer."

Dell Contact Numbers When you need to contact Dell, use the telephone numbers, codes, and electronic addresses provided in the following sections. "International Dialing Codes" provides the various codes required to make long-distance and international calls. "Americas Contact Numbers," "Europe Contact Numbers," and "Asia and Other Regions Contact Numbers" provide local telephone numbers, area codes, toll-free numbers, and e-mail addresses, if applicable, for each department or service available in various countries around the world.

If you are making a direct-dialed call to a location outside of your local telephone ser- vice area, determine which codes to use (if any) in "International Dialing Codes," in addition to the local numbers provided in the other sections.

For example, to place an international call from Paris, France to Bracknell, England, dial the international access code for France followed by the country code for the U.K., the city code for Bracknell, and then the local number as shown in the following illustration:

To place a long-distance call within your own country, use area codes instead of inter- national access codes, country codes, and city codes. For example, to call Paris, France from Montpellier, France, dial the area code plus the local number as shown in the following illustration:

The codes required depend on where you are calling from as well as the destination of your call; in addition, each country has a different dialing protocol. If you need assis- tance in determining which codes to use, contact a local or an international operator.

NOTES: Toll-free numbers are for use only within the country for which they are listed. Area codes are most often used to call long distance within your own country (not internationally)in other words, when your call originates in the same country you are calling.

Have your Express Service Code ready when you call. The code helps Dell's automated-support telephone system direct your call more efficiently.

Jumpers, Switches, and Connectors

This section provides specific information about the jumpers on the system board. It also provides some basic information on jumpers and switches and describes the connectors and sockets on the various boards in the computer.

Jumpers and SwitchesA General Explanation Jumpers and switches provide a convenient and reversible way of reconfiguring the circuitry on a printed circuit board. When reconfiguring the system, you may need to change jumper settings on the system board. You may also need to change jumper and/or switch settings on expansion cards or drives.

Jumpers Jumpers are small blocks on a circuit board with two or more pins emerging from them. 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.

NOTICE: Make sure the system is turned off before you change a jumper setting. Otherwise, damage to the system or unpredictable results may occur.

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,

support.dell.com Jumpers, Switches, and Connectors A-1

the jumper is referred to as jumpered. The jumper setting is often shown in text as two numbers, such as 1-2. The number 1 is printed on the circuit board so that you can identify each pin number based on the location of pin 1.

Figure A-1 shows the location and default settings of the jumper blocks on the system board. See Table A-1 for the designations, default settings, and functions of the sys- tem's jumpers.

Switches Switches control various circuits or functions in the computer system. The switches that you are most likely to encounter are dual in-line package (DIP) switches, which are normally packaged in groups of two or more switches in a plastic case. Two com- mon types of DIP switches are slide switches and rocker switches (see the following illustration).

Each of these switches has two positions, or settings (usually on and off). To change the setting of a slide switch, use a small, pointed object such as a small screwdriver or a straightened paper clip to slide the switch to the proper position. To change the set- ting of a rocker switch, use the screwdriver or paper clip to press down on the appropriate side of the switch. In either case, do not use a pen, pencil, or other object that might leave a residue on the switch.

System Board Jumpers Figure A-1 shows the location of the configuration jumpers on the system board. Table A-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 Chapter 4, "Using the System Setup Pro- gram," in 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.

NOTICE: See "Protecting Against Electrostatic Discharge" in the safety instructions.

1. Remove the right-side computer cover.

2. Refer to Figure A-1 for the location of the password jumper (labeled "PASSWD") on the system board.

3. Remove the jumper plug from the PASSWD jumper.

4. Replace the right-side computer 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 PASSWD jumper plug removed. However, before you assign a new system and/ or user password, you must install the jumper plug.

NOTE: If you assign a new system and/or user password with the jumper plug still removed, the system disables the new password(s) the next time it boots.

5. Repeat step 1.

6. Install the jumper plug on the PASSWD jumper.

7. Replace the right-side computer cover, and then reconnect the computer and peripherals to their electrical outlets and turn them on.

8. Assign a new system and/or user password.

To assign a new system password using the System Setup program, see "Assign- ing a System Password" in Chapter 4 of the User's Guide. To assign a new user password using the System Setup program, see "Assigning a User Password" in Chapter 4 of the User's Guide.
