Press the latch on the system front panel and lift the left cover.
In Figure 4-3, the system covers are open and the bezel is removed to provide an interior view of the system.
Figure 4-3. Inside the System
The system board can accommodate one or two microprocessors. The PCI riser board assembly accommodates up to two PCI expansion cards. Up to four memory modules may be installed on the system board.
The hard-drive bays provide space for up to three 1-inch SCSI hard drives. SCSI hard drives are connected to a SCSI controller on the system board through the SCSI backplane board.
The peripheral bays provide space for an optional 3.5-inch diskette drive and a CD drive.
The power distribution board (PDB) provides hot-plug logic and power distribution for the system. Two hot-pluggable, redundant power supplies provide power to the system board and internal peripherals.
NOTICE: If you purchased a system with redundant power supplies, you must connect both
power cables to the system; otherwise, the fans operate at the maximum RPM, which increases
the fan noise. To ensure redundancy, connect the power cables to two different electrical power
sources.
During an installation or troubleshooting procedure, you may be required to change a jumper. For information about the system board jumpers, see "Jumpers and Connectors."
Up to two half-length, PCI-X expansion cards can be installed in the system, one on each side of the riser board assembly. See Figure 4-4. The riser board assembly consists of two riser boards permanently attached to each other with plastic standoffs. It plugs into twin riser connectors on the system board and is considered an extension of the system board. See Figure 5-3.
The PCI slot locations are marked on the system board as PCI 1 and PCI 2. The PCI 1 connector on the riser board assembly is higher than the PCI 2 connector, because the PCI 1 card installs above the optional ROMB card.
Two different PCI card configurations are available:
Two PCI-X, 64-bit, 133-MHz, 3.3-V expansion cards
One PCI-X, 64-bit, 133-MHz, 3.3-V expansion card in PCI 2, and one PCI, 64-bit, 33-MHz, 5-V expansion card in PCI 1.
Figure 4-4. Riser-Board Expansion-Card Connectors
CAUTION: Before you perform the following procedure, you must turn off the system and disconnect it from its power source. See the System Information Guide for complete information about safety precautions, working inside the system, and protecting against electrostatic discharge.
Turn off the system, including any attached peripherals, and disconnect the system
from its electrical outlet.
Prepare the expansion card for installation.
See the documentation that came with the expansion card for information about configuring the card, making internal connections, or otherwise customizing the card for your system.
CAUTION: Before you perform this procedure, you must turn off the system and disconnect it from its power source. See the System Information Guide for complete information about safety precautions, working inside the system, and protecting against electrostatic discharge.
Slide the plastic expansion-card latch in the chassis wall up to the release position. See
Figure 4-5. Pivot the latch back to allow for card removal.
Grasp the expansion card by its edges, and 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: Installing a filler bracket over an empty expansion slot is necessary to maintain
Federal Communications Commission (FCC) certification of the system. The brackets also
keep dust and dirt out of the system and aid in proper cooling and airflow inside the system.
Pivot the expansion-card latch back into position and press it down firmly.
The system is upgradable to 8 GB by installing combinations of 128-, 256-, 512-MB, 1-GB, or 2-GB registered memory modules. You can purchase memory upgrade kits as needed.
NOTE: The memory modules must be rated for 266-MHz operation.
Starting with the socket closest to the edge of the system board, the memory module sockets are labeled DIMM_1A and DIMM_1B (bank 1) and DIMM_2A and DIMM_2B (bank 2). See Figure 4-6. When you install memory modules, follow these guidelines:
You must install memory modules in matched pairs (bank 1 DIMMs must match; bank 2 DIMMs must match).
Install a pair of memory modules in bank 1 before installing a second pair in bank 2.
Figure 4-6. Memory Module Sockets
Table 4-1 illustrates several sample memory configurations based on these guidelines.
To perform a memory module upgrade to the system board, perform the following steps.
CAUTION: Only trained service technicians are authorized to open the system covers and access any of the components inside the system. See the System Information Guide for complete information about safety precautions, working inside the system, and protecting against electrostatic discharge.
Reconnect the system to the electrical outlet, and turn on the system.
After the system completes the POST routine, it runs a memory test. The system detects that the new memory does not match the system configuration information and displays an error message.
Press <F2> to enter the System Setup program, and check the System Memory
setting on the System Setup screens.
The system should have already changed the value in the System Memory setting to reflect the newly installed memory.
If the System Memory value is incorrect, one or more of the memory modules may not
be installed properly. Repeat step 2 through step 7, ensuring that the memory modules
are firmly seated in their sockets.
Run the system memory test in the system diagnostics.
To install a memory module, perform the following steps:
To open the memory module socket, press down and outward on the socket latches.
See Figure 4-7.
Figure 4-7. Installing a Memory Module
Align the memory module's edge connector with the slot in the center of the memory
module socket, and insert the memory module straight down into the socket. See
Figure 4-7.
The module and the socket are keyed to prevent misalignment.
Press down on the memory module with your thumbs until the latches snap up around
the module, securing it. See Figure 4-7.
When the memory module is properly seated in the socket, the latches on the memory module socket should align with the latches on the other sockets with memory modules installed.
To remove a memory module, press down and outward on the socket latches on each end of the socket until the memory module pops out of the socket. See Figure 4-8.
Your system contains up to two Intel® Xeon™ 400- or 533-MHz front-side bus microprocessors. The 400-MHz front-side bus processors provide a minimum internal operating frequency of at least 2.0 GHz, with a front-side bus speed of 100 MHz, an address bus speed of 200 MHz (doubled address transfer rate), and a data bus speed of 400 MHz (quadrupled data transfer rate).
The system's DDR SDRAM memory modules, which are rated for 266-MHz operation, run at 200 MHz in a system using a 400-MHz front-side bus processor.
To take advantage of future options in speed and functionality, you can add a second microprocessor or replace either the primary or secondary microprocessor.
NOTICE: The second microprocessor must be of the same type and speed as the first
microprocessor.
CAUTION: Ensure that you install only microprocessors purchased from Dell and intended for this system. Using a different microprocessor could cause data loss, system damage, or personal injury.
Each microprocessor and its associated level 2 (L2) cache memory are contained in an FC-PGA2 package that is installed in a ZIF socket on the system board. The secondary microprocessor must have the same operating frequency and cache size as the primary microprocessor.
The following items are included in the microprocessor upgrade kit:
A microprocessor
A heat sink
Two retention clips
NOTE: When installing a new microprocessor, always use the new heat sink that is
shipped with the microprocessor upgrade kit. Thermal interface grease on the
underside of the heat sink is critical to maintaining optimum contact between the heat
sink and the microprocessor. Used or older heat sinks may not have enough grease
remaining on them to ensure proper contact.
The following subsections describes how to remove and install a microprocessor in either the primary or secondary microprocessor connector.
CAUTION: Only trained service technicians are authorized to open the system covers and access any of the components inside the system. See the System Information Guide for complete information about safety precautions, working inside the system, and protecting against electrostatic discharge.
To remove the two retention clips that secure the heat sink to the microprocessor
socket at both ends, press down firmly on the release tab of each retention clip until it
disengages from the socket. See Figure 4-9.
NOTICE: Never remove the heat sink from a microprocessor unless you intend to remove the
microprocessor. The heat sink is necessary to maintain proper thermal conditions.
CAUTION: The microprocessor chip and heat sink can become extremely hot. Be sure that the microprocessor has had sufficient time to cool before handling.
Figure 4-9. Retention Clip
Remove the heat sink.
NOTICE: Be careful not to bend any of the pins when removing the microprocessor. Bending
the pins can permanently damage the microprocessor.
Remove the microprocessor from the socket by pulling the socket release lever straight
up until the processor is released, and then lift the processor out of the socket. See
Figure 4-10.
If you are installing a new microprocessor, leave the release lever up so that the socket is ready for the new microprocessor.
CAUTION: Only trained service technicians are authorized to open the system covers and access any of the components inside the system. See the System Information Guide for complete information about safety precautions, working inside the system, and protecting against electrostatic discharge.
Some systems have a plastic heat-sink filler plate installed over an unused
microprocessor socket. If you are installing a second microprocessor and the plate is
present, remove the plate by pressing in the two top tabs and lifting the plate away.
NOTICE: Be careful not to bend any of the pins when unpacking the microprocessor. Bending
the pins can permanently damage the microprocessor.
Unpack the new microprocessor.
NOTICE: Identifying the pin-1 corners is critical to positioning the processor correctly.
Identify the pin-1 corner of the microprocessor, indicated by a tiny gold triangle on the
top of the microprocessor. See Figure 4-11.
Figure 4-11. Pin-1 Identification
NOTICE: Positioning the microprocessor incorrectly can permanently damage the processor
and the system when you turn on the system.
Align the pin-1 corner of the microprocessor with the pin-1 corner of the
microprocessor socket, which is also identified by a small triangle. See Figure 4-12.
Figure 4-12. Installing the Microprocessor
Install the microprocessor in the socket. See Figure 4-12.
If the release lever on the microprocessor socket is not all the way up, move it to
that position now. See Figure 4-12.
NOTICE: When placing the microprocessor in the socket, be sure that all of the pins on the
processor go into the corresponding holes of the socket. Be careful not to bend the pins.
With the pin-1 corners of the processor and socket aligned, set the processor
lightly in the socket and make sure that all pins are matched with the correct holes
in the socket.
Because the system uses a ZIF microprocessor socket, you do not need to use force (which could bend the pins if the microprocessor is misaligned). When the microprocessor is positioned correctly, it should drop down into the socket with minimal pressure.
When the processor is fully seated in the socket, rotate the socket release lever
back down until it snaps into place, securing the processor.
Peel away and discard the thin plastic cover that protects the thermal grease on the
new heat sink.
NOTE: To ensure that the proper amount of thermal interface grease is present, use the
new heat sink included in the microprocessor upgrade kit.
Place the heat sink on top of the microprocessor, grease side down. See Figure 4-13.
Replace the two retention clips:
Orient the retention clips. When installed, the clips face opposite directions:
For processor 1, the outer retention clip's release tab faces the back of the system; the inner retention clip faces the opposite direction.
For processor 2, the outer retention clip's release tab faces the front of the system; the inner retention clip faces the opposite direction.
Hook the end of the clip that is opposite the release tab over the retaining tab on
the edge of the socket.
Press the clip down so that the hole in the middle of the clip engages the tab in the
side of the socket.
Continue pressing down on the release tab (you may need to also press in on the
free end of the clip) until the end of the clip snaps over the tab on the corner of
the socket. See Figure 4-13.
Reconnect your system and peripherals to their electrical outlets, and turn them on.
As the system boots, it detects the presence of the new microprocessor and automatically changes the system configuration information in the System Setup program.
Press <F2> to enter the System Setup program, and check that the microprocessor
categories match the new system configuration. See "Using the System Setup
Program" for instructions.
Run the system diagnostics to verify that the new microprocessor is operating
correctly.

and the rear fan.
Lower the system board into the chassis, left side first to protect the PDB, control
panel, and rear fan cables. Press the system board evenly onto all the grounding tabs on
the floor of the chassis.
Slide the system board toward the back of the chassis as far as it will go, about 6.3 mm
(0.25 inch).
Tighten the thumbscrew to secure the system board.
Check to ensure that the system board jumpers are set to the same settings as the
board you removed.
Install the optional RAC, if it was installed on the board you removed. See Figure 5-3
for the location of the RAC connector; see the RAC documentation for more
information.
Install the optional ROMB card and its backup battery, if they were installed on the
board you removed. See "Installing a ROMB Card."
Press the PCI riser board assembly firmly into its connectors.
The three internal hard-drive bays accommodate up to three 1-inch SCSI hard drives that connect directly to the SCSI backplane board. No drive cables are necessary.
SCSI hard drives are supplied in special drive carriers that fit in the hard-drive bays.
NOTICE: Before attempting to remove or install a drive while the system is running, see the
documentation for the host adapter to ensure that the host adapter is configured correctly to
support hot-pluggable drive removal and insertion.
NOTE: It is recommended that you use only drives that have been tested and approved
for use with the SCSI backplane board.
You may need to use different programs than those provided with the operating system to partition and format SCSI hard drives.
NOTICE: Do not turn off or reboot your system while the drive is being formatted. Doing so can
cause a drive failure.
When you format a high-capacity SCSI hard drive, allow enough time for the formatting to be completed. Long format times for these drives are normal. A 9-GB hard drive, for example, can take up to 2.5 hours to format.
For systems with a ROMB card, power down the hard-drive bay and wait until the
SCSI hard-drive indicators on the drive carrier signal that the drive can be removed
safely.
If the drive has been online, the green power on/fault indicator will flash as the drive is powered down. When both drive indicators are off, the drive is ready for removal.
Open the hard-drive handle to release the drive.
Slide the hard drive out until it is free of the drive bay.
Replace the optional front bezel, if one was attached. See "Replacing the Bezel."
Follow these general guidelines when connecting external SCSI hard drives to the external SCSI connector on the system's back panel or to a SCSI controller card.
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your System Information Guide for complete information about safety precautions, working inside the system, and protecting against electrostatic discharge.
If you plan to boot the system from a hard drive, the drive must be attached to the primary (or boot) controller. The device that the system boots from is determined by the boot order specified in the System Setup program. See "Using the System Setup Program."
This section describes how to configure and install an external SCSI tape drive with an add-in PCI controller card.
NOTE: The integrated SCSI controller does not support mixed mode (one channel
SCSI and one channel RAID). For this reason, in a system with RAID, Dell does not
support an external tape drive connected to the external SCSI controller.
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your System Information Guide for complete information about safety precautions, working inside the system, and protecting against electrostatic discharge.
Ground yourself by touching an unpainted metal surface on the back of the system,
unpack the drive and controller card, and configure the tape drive according to the
tape drive documentation, based on the following guidelines:
Each device attached to a SCSI host adapter must have a unique SCSI ID
number. (Narrow SCSI devices use IDs 0 to 7; wide SCSI devices use IDs from 0
to 15).
A SCSI tape drive is typically configured as SCSI ID 6.
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.
SCSI logic requires that the two devices at opposite ends of a SCSI chain be
terminated and that all devices in between be unterminated. Therefore, you
enable the tape drive's termination if it is the last device in a chain of devices (or
sole device) connected to the SCSI controller.
The optional diskette drive is installed in a carrier that slides into the peripheral bay. Perform the following steps to install a diskette drive.
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your System Information Guide for complete information about safety precautions, working inside the system, and protecting against electrostatic discharge.
If a filler plate is installed in the drive bay, remove it now.
If the carrier and the drive were supplied separately, install the drive in the carrier. See
Figure 4-24.
Figure 4-24. Installing a Diskette Drive in a Carrier
