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, 64-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.

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

(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 an 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 1 lists the various codes for the hot-plug LED indicators.

Table 1. Hot-Plug Indicator Patterns

Removing an Expansion Card

To remove an expansion card, perform the following steps.

NOTE: To help facilitate the removal of some of the smaller PCI expansion cards (such as the Intel EtherExpress PRO/100+ NIC), card extractors are available for purchase from other suppliers.

Open the expansion-card door.

NOTICE: 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 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 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 4).

Figure 4. 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 5).

Rotate the latch away from the expansion-card bracket to release the bracket (see Figure 5).

Figure 5. 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 5).

CAUTION: Some expansion cards can become quite 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 4).
If you are replacing an expansion card, remove the existing card by following steps 4 through 7 of "Removing an Expansion Card."
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 5).
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 5).
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.

Adding Memory

The eight dual in-line memory module (DIMM) sockets on the system board (see Figure 1) can accommodate 128 megabytes (MB) to 4 gigabytes (GB) of dynamic random-access memory (DRAM), in 128-MB increments.

Memory Upgrade Kits

The system is upgradable to 4 GB by installing combinations of 64-, 128- 256-, and 512-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 6). 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 its AC power source. For more information, see "Safety First—For You and Your Computer."

Shut down the system and disconnect it from its power source.
Remove the computer cover.
Remove the support panel.
Remove the cooling shroud.
Locate the DIMM sockets in which you will install or replace DIMMs.
Figure 1 shows the relative location of the DIMM sockets on the system board. Figure 6 shows the labeling of the DIMMs sockets.

NOTICE: See "Protecting Against Electrostatic Discharge."

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:

Press down and outward on the ejectors on the DIMM socket, as shown in Figure 7, to allow the DIMM to be inserted into the socket.

Figure 7. 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 7).
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 7).

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 8).

Upgrading the Microprocessor or Installing a Secondary Microprocessor

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 9).

Replacing the SEC Cartridge and Heat Sink Assembly

To install the replacement SEC cartridge and heat sink assembly, perform the following steps:

Remove the terminator card or old SEC cartridge from the guide bracket assembly.
Slide the SEC cartridge into the guide bracket assembly, and firmly seat the assembly until the tabs on the guide bracket assembly snap into place over the ends of the cartridge.
Replace the cooling shroud and computer cover.

Activating the Integrated RAID Controller

To activate the integrated PowerEdge Expandable RAID Controller (PERC) 3/Di redundant arrays of independent disks (RAID) controller, follow these steps.

NOTICE: To avoid possible data loss, back up all data on the hard-disk drives before changing the mode of operation of the integrated SCSI controller.

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.
Press the ejectors on the RAID DIMM socket down and outward, as shown in Figure 7, to allow the DIMM to be inserted into the socket.
See Figure 1 for the location of the socket on the system board.

NOTE: The RAID controller DIMM must be an unbuffered DIMM, rated to run at 100 MHz or faster. Do not substitute registered DIMMs such as those used for system memory.

Align the RAID 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 7).
The DIMM socket has two alignment keys that allow the DIMM to be installed in the socket in only one way.

Replace the cooling shroud and computer cover; reconnect the computer and peripherals to their AC power sources and turn them on.
Install the RAID software.
For details, refer to the RAID controller documentation.

Replacing the System 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 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

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 unplug the system for a few hours, and then plug in and turn it on again. Enter the System Setup program. If the date and time are not correct in the System Setup program, replace the battery.

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

If the system is turned off for long periods of time (for weeks or months), 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.

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.

Enter the System Setup program and, if possible, make a printed copy of the System Setup screens.
See "Using the System Setup Program" in the User's Guide for instructions.

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."

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

NOTICE: See "Protecting Against Electrostatic Discharge."

Remove the computer cover.
Remove the cooling shroud.
Remove all expansion cards.
Remove the PCI insulator.
To remove the PCI insulator, release the two latches on the insulator along the inner wall of the system tray, then lift the PCI insulator from the system.
Remove the battery.
Pry the battery out of its socket with your fingers or with a blunt, nonconductive object such as a plastic screwdriver.
Install the new battery with the side labeled "+" facing up (see Figure 13).

Figure 13. Installing the Battery

Reinstall the PCI insulator.
Reinstall the expansion cards.
Replace the cooling shroud and computer cover, and then reconnect the computer and peripherals to their AC power sources and turn them on.
Enter the System Setup program to confirm that the battery is operating properly.
Enter the correct time and date through the System Setup program's Time and Date settings. Also reenter any system configuration information that is no longer displayed on the System Setup screens, and then exit the System Setup program.
To test the newly-installed battery, turn off and disconnect the system from the electrical outlet for at least an hour.
After an hour, plug in and turn on the system and enter the System Setup program. If the time and date are still incorrect, see "Getting Help" for instructions on obtaining technical assistance.
