Safety First—For You and Your Computer

The procedures in this guide require that you remove the cover and work inside the computer. While working inside the computer, do not attempt to service the computer except as explained in this guide and elsewhere in Dell documentation. Always follow the instructions closely.

Working inside the computer is safe—if you observe the following precautions.

WARNING: This system may have more than one power supply cable. To reduce the risk of electrical shock, a trained service technician must disconnect all power supply cables before servicing the system. For more information, refer to "Safety First—For You and Your Computer."

WARNING: The power supplies in your computer system may produce high voltages and energy hazards, which can cause bodily harm. Only trained service technicians are authorized to remove the computer covers and access any of the components inside the computer.

WARNING FOR YOUR PERSONAL SAFETY AND PROTECTION OF THE EQUIPMENT

Before starting to work on the computer, perform the following steps in the sequence listed:

Turn off the computer and all peripherals (unless you are installing or removing a hard-disk drive or hot-plug expansion card).

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 the computer.

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

Disconnect the computer and peripherals from their power sources (unless you are installing or removing a hot-pluggable component such as a hard-disk drive or hot-plug expansion card). Also, disconnect any telephone or telecommunications lines from the computer.

Doing so reduces the potential for personal injury or shock.

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 computer’s electronic components, such as the microprocessor. You can do so by touching an unpainted metal surface on the computer chassis.

As you continue to work inside the computer, periodically touch an unpainted metal surface to remove any static charge your body may have accumulated.

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 addition, Dell recommends that you periodically review the safety instructions for this system.

Computer Cover

Inside the Chassis

In Figure 7, the computer cover and interior support panel are removed to provide an interior view. Refer to this illustration to locate interior features and components discussed later in this guide.

The system board holds the computer's control circuitry and other electronic components. The SCSI backplane board connects the system's hard-disk drives to a SCSI host adapter on the system board or on an expansion card. Power cables leading from the PSPB supply power to the system board, SCSI backplane board, and externally accessible drives.

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 expansion card. (For more information, see "Drives" and "SCSI 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 "Jumpers, Switches, and Connectors."

Drives

The external drive bays at the front of your system hold up to three user-accessible, half-height 5.25-inch devices (typically CD-ROM or tape drives). A SCSI CD-ROM drive is standard in the first external drive bay, while two additional devices of your choice can be installed in the next two external drive bays. SCSI devices in the external drive bays may be connected to the Ultra/Narrow or Ultra3 SCSI controller on the system board, or a SCSI controller on an expansion card. A fourth drive bay accommodates a standard 3.5-inch diskette drive, which is controlled by the diskette drive controller on the system board. See Figure 8 for a general view of the various drives, connector cables, and power cables in the external drive bays.

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) shielding 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 following steps.

NOTICE: See "Protecting Against Electrostatic Discharge."

Remove the front bezel.

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.

Pull the insert out of the bezel.

Removing a Metal Insert

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

Remove the front bezel.

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

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

Drive Connections

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 four-wire DC power cable from the system power supply. The connectors on these cables are labeled "FD1," "FD2," "FD3," "FD4," and "FD5." Connectors FD1 through FD4 are used for 5.25-inch devices; connector FD5 is used for the 3.5-inch diskette drive.

Externally-Accessible Drives

To remove a 3.5-inch diskette drive or a 5.25-inch drive assembly from one of the externally accessible drive bays, perform the following steps.

NOTICE: See "Protecting Against Electrostatic Discharge."

Disconnect the DC power cable and the interface cable from the back of the drive.

Be sure to record the power connector number and the location of the interface cable connector.

Press inward (toward the center of the drive) on the two drive-release tabs, and slide the drive out of the
bay (see Figure 9).

If the drive is a SCSI drive, record the setting of the SCSI address jumpers and SCSI bus termination jumper.

If present, remove the 50-pin to 68-pin adapter from the SCSI connector on the back of the drive.

Some drives use a 50-pin to 68-pin adapter between the SCSI cable and the drive connector. Check the back of the drive for an adapter. If present, remove it and retain it for use on the new drive.

NOTE: When you reinstall a SCSI drive, set the SCSI address jumpers and the SCSI bus termination jumpers to the settings you recorded.

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.

A SCSI CD-ROM drive is usually configured as SCSI ID 5.

NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or that devices be attached to the cable in order by ID number.

Device Termination

SCSI logic requires that the two devices at opposite ends of the SCSI chain be terminated and that all devices in between be unterminated. 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 That Uses a Controller Card

Tape drives, autoloaders, and other SCSI devices that require their own separate controller cards are shipped with the controller card and an interface cable.

To install the tape drive or other device in an external drive bay, perform the following steps.

NOTICE: See "Protecting Against Electrostatic Discharge."

Configure the controller card if necessary.

Refer to the documentation that came with the device 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.

Remove the computer cover and front bezel.

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.

Install the controller card in an expansion slot.

Slide the system board tray to its service position.

If other installed drives interfere with access to the back of the tape drive, disengage them by pressing in on the plastic drive rails at the front of the bay, and slide them slightly toward the front of the chassis.

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.

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

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.

If you moved other drives in step 6, snap them back into place.

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 airflow of the fans or cooling vents.

Slide the system board tray back into the system chassis.

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

Replace the front bezel and computer cover.

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

Perform a tape backup and verification test with the drive as instructed in the tape-drive software documentation that came with the drive.

SCSI Hard-Disk Drives

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 First—For You and Your Computer."

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

Figure 13 illustrates the hard-disk drive bays, the hot-plug SCSI backplane board, and the Ultra3 SCSI cable. The Ultra3 SCSI cable has two connectors:

The connector at one end attaches to the Ultra3 SCSI host adapter connector labeled "PRIMARY SCSI A" 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.

Preparing SCSI Hard-Disk Drives for Installation

NOTE: 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 system to partition and format SCSI hard-disk drives. See "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 formatted. 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.

SCSI Hard-Disk Drive Replacement

SCSI hard-disk drives are supplied by Dell in special drive carriers that fit in the hard-disk drive bays. To install a SCSI hard-disk drive, perform the following steps.

NOTICE: See "Protecting Against Electrostatic Discharge."

NOTICE: Systems without an activated Dell PERC 3/Di integrated redundant array of independent disks (RAID) controller or a Dell PERC 2 host adapter card do not support hot plug drive installation.

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

Open the front bezel and unlock the hard-disk drive keylock (see Figure 14).

Figure 14. Installing a SCSI Hard-Disk Drive Carrier

1	Hard-disk drive keylock
2	Hard-disk drive carrier
3	Hard-disk drive carrier handle

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.

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

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

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 14).

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

Lock the hard-disk drive keylock (see Figure 14).

Close the front bezel.

Install any required SCSI device drivers.

See "Installing and Configuring SCSI Drivers" in the User's Guide for information.

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

SCSI Backplane Board

To replace a SCSI backplane board with an identical replacement or with a different backplane board, perform the following steps.

WARNING: Before you perform this procedure, you must turn off the computer and disconnect it from its AC power source. For more information, see "Safety First—For You and Your Computer."

NOTICE: See "Protecting Against Electrostatic Discharge."

Unpack the SCSI backplane board upgrade kit.

Remove the computer cover and front bezel.

NOTICE: You must remove all hard-disk drives to avoid damaging the SCSI backplane board when you remove it later in this procedure.

Remove the hard-disk drives from the system.

Slide the system board tray to its service position (see Figure 15).

Disconnect the Ultra3 SCSI cable from the SCSI backplane board.

To avoid damage to the cable, use the strain-relief loop to disconnect the cable.

Disconnect the flat data cable from the locking connector on the backplane board.

Disconnect the power cable labeled "HD-B/P" from the power connector labeled "POWER" on the backplane board by pressing the latch on the side of the connector.

Disconnect the fan power cable from the power connector labeled "FAN" on the backplane board.

To release the connector, press the latch on the side of the connector.

Loosen the captive thumbscrew on the backplane board (see Figure 15).

Slide the SCSI backplane board away from the chassis inner wall approximately 1 centimeter (cm) (a quarter inch), and then lift the board off of the L-shaped mounting tabs and away from the chassis (see Figure 15).

Reinstall the lower drive key using the three screws.

To reinstall the upper drive key, lock the drive-locking flange and reinstall the three screws through the flange cutouts.

Replace the front bezel and computer cover.

Reinstall the hard-disk drives in the computer.

NOTE: You can use only 1-inch hard-disk drives with an 8-bay backplane—you cannot use 1.6-inch hard-disk drives. (A 6-bay backplane can accommodate 1.6-inch or 1-inch drives.) If you install an 8-bay backplane, you need to convert the drive carriers to the 1-inch width by removing the spacer insert that fastens to each carrier adjacent to the carrier release handle.

Reconnect the computer and peripherals to their AC power sources.

Configuring the Boot Device

If you plan to boot the system from a hard-disk drive, the drive must be attached to the primary (or boot) controller or SCSI host adapter card. You can select the primary controller using the System Setup program. See "Using the System Setup Program" in the User's Guide for instructions.

Power Supplies

Your system may contain two nonredundant power supplies or three redundant, hot-pluggable power supplies. The two indicators on the back of each power supply (see Figure 19) signal the power supply's current status. If the red (lower) failure indicator lights up while the system is operating, replace the power supply as described in the following subsection.

Removing and Replacing a Power Supply

To replace a power supply, perform the following steps.

NOTICE: See "Protecting Against Electrostatic Discharge."

NOTICE: A power supply is heavy. Support it with both hands when installing or removing it.

Remove the power supply-bay close-out panel from the back of the system chassis if you are adding a power supply to an empty bay.

To open the handle of the new power supply, press the handle release in the middle of the power supply handle toward the center of the power supply (see Figure 19).

Cooling Fans

Five cooling fans are installed in the system chassis. Two fans are located on the front of the system board tray adjacent to the microprocessor(s), and three fans are mounted in a removable assembly adjacent to the hard-disk drive bays.

The three-fan assembly for the hard-disk drives is hot-pluggable; that is, you can remove the entire three-fan assembly and replace it with another three-fan assembly while the system is running. If you want to replace the individual fans in the assembly, you must turn off the system before removing the fan assembly to prevent system overheating while the individual fan is replaced.

On the two-fan assembly for the system board, you can hot-plug the individual fans, but only a single fan at a time. Because the fans in the two-fan assembly can be removed and replaced without removing the assembly from the system, you can replace either fan while the system is running.

NOTICE: You can only hot-plug the fans in the two-fan assembly one fan at a time. Removing more than a single fan from operation at one time can result in system overheating.

If you observe that one of the cooling fans is not operating or if the Dell Hardware Instrumentation Package (HIP) server-management application issues a fan-related error message, perform the following steps to troubleshoot the problem.

NOTICE: See "Protecting Against Electrostatic Discharge."

Remove the computer cover.

Check the fan power connections:

Check the fan power cable connection to the SCSI backplane board.

For the three-fan assembly for the hard-disk drives, remove the assembly and reinstall it, making sure that the electrical connector is fully seated.

Do the fans operate properly?

Yes. You have fixed the problem.

No. Replace the defective fan or fan assembly as described in the following subsections.

Replacing a Fan in the Two-Fan Assembly

To replace a defective cooling fan in the two-fan assembly, perform the following steps.

NOTICE: You can only hot-plug the fans in the two-fan assembly one fan at a time. Removing more than a single fan from operation at one time can result in system overheating. To maintain proper airflow within the system, do not remove the faulty fan until you are ready to replace it.

NOTE: You can perform the following procedure with the system turned on or off.

NOTICE: See "Protecting Against Electrostatic Discharge."

Remove the computer cover.

Identify the defective cooling fan in the assembly.

Remove the faulty cooling fan from the fan assembly by releasing the fan retention tab on the assembly and sliding the fan out of the carrier (see Figure 22).

Hot-Plug Expansion Cards

If your computer uses the Novell® NetWare® 5.0 or Microsoft® Windows® 2000 (Release Candidate 2 or later versions) operating system, connectors PCI1 through PCI4 support hot plug replacement and addition of PCI expansion cards.

For systems using NetWare 5.0, the following minimum configuration is required to support hot-plug expansion cards:

Novell NetWare 5.0 symmetric multiprocessing (SMP) operating system with Support Pack 2A or later

The latest Dell system-bus driver, as provided on the Dell OpenManage Server Assistant CD

The following PCI expansion cards are supported:

Intel® EtherExpress™ PRO/10+ server adapter card

Intel EtherExpress PRO/100+ server adapter card

Intel EtherExpress PRO/100+ Dual Port server adapter card

Intel PRO/1000 server adapter card

NOTE: Other cards may be qualified for hot-plug operations by Dell in the future; contact Dell for current information.

NOTICE: If you attempt hot-plug addition or replacement of a unsupported card, the system may freeze or shut down unexpectedly.

Connectors PCI1 through PCI4 support hot-plug replacement of PCI expansion cards. Pairs of light-emitting diodes (LEDs) adjacent to each expansion slot display the expansion card connectors' current status. Table 2 lists the various codes for the hot-plug LED indicators

Table 2. Hot-Plug Indicator Patterns

Choosing an Expansion Slot

Follow these guidelines when you add an expansion card:

Connectors PCI1 through PCI4 support hot plug replacement and addition of PCI expansion cards. (Verify that the expansion card supports hot-plug capability.)

Install 64-bit, 66-megahertz (MHz), 3 volt (V) PCI expansion cards in connectors PCI1 and PCI2. (You may also install 32-bit cards in these connectors.)

NOTES: If connectors PCI1 and PCI2 are both empty and you hot-add a 66-MHz card, the card will operate at 33 MHz until you reboot the system.

Installing a 33-MHz card in either connector will limit the bus speed of both connectors to 33 MHz.

If PCI1 or PCI2 is occupied by a card running at 66-MHz and you hot-add a 33-MHz card in the empty 66-MHz slot, you must reset the system so that the 33-MHz expansion card is activated; both cards will then run at 33-MHz.

Install 64-bit, 33-MHz, 5-V PCI expansion cards in connectors PCI3 through PCI6. (You may also install 32-bit cards in these connectors.)
Install 32-bit, 33-MHz cards in connector PCI7.

NOTE: If you install a Dell OpenManage™ Remote Assistant Card (DRAC), version 2.0, you must install this expansion card in connector PCI7.

Expansion Card Removal

To remove an expansion card, perform the following steps.

NOTICE: See "Protecting Against Electrostatic Discharge."

Open the expansion-card door.

NOTICE: To avoid damage to the card or your computer, you must power down the expansion slot (expansion slots PCI1 through PCI4), or shut down the system (all other expansion slots) before you remove an expansion card.

Remove power from the expansion slot by using one of the following methods:

If the expansion slot (slots PCI5 through PCI7) or the expansion card itself does not support hot-plug removal, or your computer's operating system does not support hot-plug PCI cards, shut down the system, including any attached peripherals, and disconnect the system from its electrical outlet.

If your computer uses the NetWare 5.0 operating system, run ncmcon.nlm to place the affected slot in the off state.

NOTE: If all slots are reported with No in the Hot Plug column, press the <Esc> key to exit the ncmcon utility and ensure that dellsbd.nlm is loaded; then restart the utility by running the load ncmcon.nlm command.

If your computer uses the Windows 2000 operating system, press the switch next to the expansion slot to power down the expansion-card connector, or run the Unplug or Eject Hardware control applet from the status bar.

The green LED flash as the expansion-card connector is powered down. When both indicator lights adjacent to the expansion slot are off, the card may be safely removed.

If you are removing a card from non-hot-plug connectors PCI5, PCI6, or PCI7, remove the plastic expansion slot cover by lifting the release tab (see Figure 26).

Figure 26. Non-Hot Plug Expansion Slot Cover

1	Release tab
2	Non-hot plug expansion card cover

Disconnect any cables attached to the expansion card you want to remove.

Be sure to record the location of each cable before you disconnect it.

The bracket on the expansion card is secured by a plastic latch (see Figure 27).

Rotate the latch away from the expansion-card bracket to release the bracket (see Figure 27).

Figure 27. Expansion-Card Latches

1	Plastic card guide
2	Expansion-card latch
3	Expansion card

If the expansion card is a full-length card, release the card's inner end by opening the tab on the plastic card guide (see Figure 27).

CAUTION: Some expansion cards can become warm during system operation. Be sure that the card has had sufficient time to cool after the connector is powered down before you touch the card.

Grasp the expansion card by its top corners, and carefully remove it from the expansion-card connector.

If you are removing the card permanently, install a metal filler bracket over the empty card-slot opening.

NOTE: You must install a filler bracket over an empty expansion slot to maintain Federal Communications Commission (FCC) certification of the system. The brackets also keep dust and dirt out of the computer and help to maintain proper cooling and airflow inside the computer.

If you removed a card from non-hot-plug connectors PCI5, PCI6, or PCI7, reinstall the plastic expansion slot cover.

Close the expansion-card door.

If you shut down the system prior to installing the card, reconnect the computer and peripherals to electrical outlets, and turn them on.

Installing an Expansion Card

To install an expansion card, perform the following steps.

NOTICE: See "Protecting Against Electrostatic Discharge."

Open the expansion-card door.

NOTICE: You can only perform hot-plug replacement of an existing card with an identical replacement card.

NOTICE: To avoid damage to the card or your computer, you must power down the expansion slot before you install an expansion card.

Remove power from the expansion slot by using one of the following methods:

If the expansion slot (slots PCI5 through PCI7) or the expansion card itself does not support hot-plug removal, or your computer's operating system does not support hot-plug PCI cards, shut down the system, including any attached peripherals, and disconnect the system from its electrical outlet.

If your computer uses the NetWare 5.0 operating system, run ncmcon.nlm to place the affected slot in the off state.

NOTE: If all slots are reported with No in the Hot Plug column, press the <Esc> key to exit the ncmcon utility and ensure that dellsbd.nlm is loaded; then restart the utility by running the load ncmcon.nlm command.

If your computer uses the Windows 2000 operating system, press the switch next to the expansion slot to power down the expansion-card connector, or run the Unplug or Eject Hardware control applet from the status bar.

The green LED will flash as the expansion-card connector is powered down. When both indicator lights adjacent to the expansion slot are off, the card may be safely removed.

If you are installing a card in non-hot-plug connectors PCI5, PCI6, or PCI7, remove the plastic expansion slot cover by lifting the release tab (see Figure 26).

If you are replacing an expansion card, remove the existing card by following steps 4 through 7 of "Expansion Card Removal."

Prepare the expansion card for installation.

See the documentation that came with the expansion card for information on configuring the card, making internal connections, or otherwise customizing the card for the system.

To remove the expansion-slot filler bracket from an unoccupied expansion slot, rotate the latch away from the expansion-card bracket to release the bracket (see Figure 27).

Insert the card-edge connector firmly into the expansion-card connector on the chassis.

When the card is firmly seated in the connector and the card-mounting bracket is aligned with the brackets on either side of it, close the expansion-card latch.

If the expansion card is a full-length card, secure the inner end of the card by closing the plastic latch on the card guide over the top edge of the card (see Figure 27).

Connect any cables that should be attached to the card.

See the documentation that came with the card for information about cable connections.

If your computer uses the Windows 2000 operating system, press the PCI hot-plug switch again to restore power to the expansion slot.

The green LED adjacent to the expansion slot will flash and then remain illuminated when power is restored.

If you installed a card in non-hot-plug connectors PCI5, PCI6, or PCI7, reinstall the plastic expansion slot cover.

Close the expansion card door.

NOTES: If connectors PCI1 and PCI2 are both empty and you hot-add a 66-MHz card, the card will operate at 33 MHz until you reboot the system.

If your computer uses the NetWare 5.0 operating system, run the ncmcon.nlm utility to restore power to the expansion slot occupied by the new PCI expansion card.

If your computer uses the NetWare 5.0 operating system, the replacement adapter card is not automatically bound when the slot is turned on, and you are using the Transmission Control Protocol/Internet Protocol (TCP/IP), enter the following command on the system console to reinitialize the system and bind the new card to the network:

reinitialize system

If you shut down the system prior to installing the card, reconnect the computer and peripherals to electrical outlets, and turn them on.

DIMMs

The eight dual in-line memory module (DIMM) sockets on the memory board (see Figure 28) can accommodate 128 megabytes (MB) to 2 gigabytes (GB) of dynamic random-access memory (DRAM), in 128-MB increments.

Memory Upgrade Kits

The system is upgradable to 2 GB by installing combinations of 64-, 128-, and 256-MB registered DIMMs. You can purchase memory upgrade kits from Dell as needed.

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

DIMM Installation Guidelines

The DIMM sockets are arranged in two groups of four sockets each. Sockets DIMM_A, DIMM_C, DIMM_E, and DIMM_G are associated with the primary North Bridge circuit, while sockets DIMM_B, DIMM_D, DIMM_F, and DIMM_H are associated with the secondary North Bridge circuit (see Figure 28). You can improve system performance by distributing memory equally between these two groups of DIMMs. When you install DIMMs, follow these guidelines:

Install DIMMs in pairs, beginning with sockets DIMM_A and DIMM_B, then sockets DIMM_C and DIMM_D, and so on.

Both DIMMs in a pair must be the same size.

If you install different sizes of DIMMs, install them in order of descending capacity, beginning with the highest-capacity DIMMs in sockets DIMM_A and DIMM_B.

Performing a Memory Upgrade

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

WARNING: Before you perform this procedure, you must turn off the computer and disconnect it from the electrical outlet. For more information, see "Safety First—For You and Your Computer."

NOTICE: See "Protecting Against Electrostatic Discharge."

Shut down the system, including any attached peripherals, and disconnect the system from the electrical outlet.

Remove the computer cover.

Remove the interior support panel.

Remove the cooling shroud.

Locate the DIMM sockets in which you will install or replace DIMMs.

Figure 33 shows the relative location of the DIMM sockets on the system board. Figure 28 shows the labeling of the DIMMs sockets.

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

Replace the cooling shroud, support panel, 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) routine, it runs a memory test that displays the new memory total, which includes all newly installed memory.

NOTE: If the memory total is incorrect, turn off and disconnect the computer and peripherals from their AC power sources, remove the computer cover, and check all the installed DIMMs to make sure they are seated properly in their sockets. Then repeat step 6.

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:

Press <F1> to continue; <F2> to enter System Setup

Press <F2> to enter the System Setup program, and check the System Memory field on the System Setup screens. The system should have already changed the value in the System Memory field to reflect the newly installed memory. If the value is incorrect, one or more of the DIMMs may not be installed properly. Repeat steps 1 through 8, checking to make sure that the DIMMs are firmly seated in their sockets.
Run the system memory test in the Dell Diagnostics.

Installing DIMMs

To install a DIMM, perform the following steps.

NOTICE: See "Protecting Against Electrostatic Discharge."

Press down and outward on the ejectors on the DIMM socket, as shown in Figure 29, to allow the DIMM to be inserted into the socket.

Figure 29. Installing a DIMM

1	DIMM socket ejectors (2)
2	Alignment keys (2)

Align the DIMM's edge connector with the slot in the center of the DIMM socket, and insert the DIMM in the socket (see step A in Figure 29).

The DIMM socket has two alignment keys that allow the DIMM to be installed in the socket in only one way.

Press down on the DIMM with your thumbs while pulling up on the ejectors with your index fingers to lock the DIMM into the socket (see step B in Figure 29).

When the DIMM is properly seated in the socket, the ejectors on the DIMM socket should align with the ejectors on the other sockets with DIMMs installed.

Repeat steps 1 through 3 to install the remaining DIMMs.

Continue with step 7 of "Performing a Memory Upgrade."

Removing DIMMs

To remove a DIMM, press down and outward on the ejectors on each end of the socket until the DIMM pops out of the socket (see Figure 30).

Figure 30. Removing a DIMM

Microprocessor and Heat Sink

Each microprocessor is contained within a single-edge contact (SEC) cartridge and heat sink assembly. The system board has two guide bracket assemblies, which hold the SEC cartridge and heat sink assemblies. If your system has only one microprocessor, the secondary guide bracket assembly must contain a terminator card.

If you add a second microprocessor to the system, its maximum speed need not match that of the primary microprocessor, but the internal operating speed of the faster microprocessor will be reduced to match the speed of the slower microprocessor. For example, if a 667-MHz microprocessor is added to a system containing a 600-MHz primary microprocessor, both microprocessors will operate at an internal speed of 600 MHz.

NOTICE: If you are upgrading a system by installing a secondary microprocessor, you must order an upgrade kit from Dell. The upgrade kit from Dell contains the correct version of the microprocessor for use as a secondary microprocessor.

Removing a Terminator Card

To remove a terminator card, perform the following steps.

WARNING: Before you perform this procedure, you must turn off the computer and disconnect it from its AC power source. For more information, see "Safety First—For You and Your Computer."

Turn off the system, including any attached peripherals, and disconnect the AC power cable from its power source.

NOTICE: See "Protecting Against Electrostatic Discharge."

Remove the computer cover.

Remove the cooling shroud.

Slide the terminator card up and out of the guide bracket assembly (see Figure 31).

Figure 31. Removing a Terminator Card

2	Guide bracket assembly
3	Terminator card

Installing a Terminator Card

NOTICE: You cannot use 100-MHz-only front-side bus (FSB) terminator cards from earlier PowerEdge systems in a PowerEdge 4400 system; you must use the new 133-MHz terminator card. However, you can use the new 133-MHz terminator card in older systems running at 100 MHz.

You can tell the difference between the 100-MHz and 133-MHz terminator cards by looking at them; while both use the same plastic housing, the internal board on the 133-MHz terminator cards is about half the size of the older terminator cards.

To install a terminator card, align the notch on the terminator card with the socket on the guide bracket assembly and guide the card into the empty guide bracket assembly.

Removing the SEC Cartridge and Heat Sink Assembly

To remove the SEC cartridge and heat sink assembly, perform the following steps.

WARNING: Before you perform this procedure, you must turn off the computer and disconnect it from the electrical outlet. For more information, see "Safety First—For You and Your Computer."

	CAUTION: The SEC cartridge and heat sink assembly can get extremely hot during system operation. Be sure the assembly has had sufficient time to cool before you touch it.
	CAUTION: When handling the SEC cartridge and heat sink assembly, take care to avoid sharp edges on the heat sink.

NOTICE: Every slot must be occupied by either a microprocessor or a terminator card.

NOTICE: See "Protecting Against Electrostatic Discharge."

Turn off the system, including any attached peripherals, and disconnect the AC power cable from its power source.

Remove the computer cover.

Remove the support panel.

NOTICE: If you need to remove the guide-bracket assembly, note that the plastic parts do not interlock as on older systems.

Pull the tabs on each side of the guide bracket away from the ends of the cartridge, then lift the cartridge and heat sink assembly away from the guide bracket assembly (see Figure 32).

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 battery 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 one of the following or similar messages:

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

System CMOS checksum bad -- Run SETUP
Strike the F1 key to continue, F2 to run the setup utility

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 and disconnect the system from the electrical outlet for a few hours, and then reconnect and turn the system on again. Enter the System Setup program. If the date and time are not correct in the System Setup program, replace the battery.

NOTES: Some software may cause the system time to speed up or slow down. If the system seems to operate normally except for the time kept in the System Setup program, the problem may be caused by software rather than by a defective battery.

If the system is turned off for long periods of time (for weeks or months), the NVRAM may lose its system configuration information. This situation is not caused by a defective battery.

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, perform the following steps.

NOTICE: See "Protecting Against Electrostatic Discharge."

WARNING: Before you perform this procedure, you must turn off the computer and disconnect it from the electrical outlet. For more information, see "Safety First—For You and Your Computer."

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