12 Description
Processor
Each Pentium II or Pentium III processor is packaged in a cartridge. The cartridge includes the
processor core with an integrated 16 KB primary (L1) cache, the secondary (L2) cache, and a back
cover.
The processor implements the MMX™ technology and maintains full backward compatibility with
the 8086, 80286, Intel386™, Intel486™, Pentium, Pentium Pro and previous Pentium II processors.
The processor’s numeric coprocessor significantly increases the speed of floating point operations
and complies with ANSI/IEEE standard 754-1985.
Each processor cartridge connects to the server board through a 242 pin edge connector. The
cartridge is secured by a retention mechanism attached to the server board. Depending on
configuration, your server may have one or two processors.
The processor external interface is MP (Multi-Processor) ready and operates at 100 MHz. The
processor contains a local APIC (Advanced Programmable Interrupt Controller) section for
interrupt handling in MP and UP (Uni-Processor) environments.
The second level cache is located on the substrate of the S.E.C. cartridge. The cache includes burst
pipelined synchronous static RAM (BSRAM). The L2 cache is offered in 512 KB configurations
only, with error correcting code (ECC) that operates at half the core clock rate.
✏ NOTE
If you install a processor that is 550 MHz or faster, and you use the server
management feature board, you must run the FRUSDR update utility.
Memory
Only 100 MHz PC/100 ECC or Non-ECC SDRAM is supported by the server board. Memory is
partitioned as four banks of SDRAM DIMMs, each providing 72 bits of noninterleaved memory
(64 bit main memory plus ECC):
• Install from 64 MB to 2 GB of memory, using registered DIMMs.
• Install from 32 MB to 1 GB of memory, using unbuffered DIMMs.
Memory should be added in order from slot 1 to slot 4.
✏ NOTE
Do not mix registered and unbuffered memory. Non ECC memory may be
installed but ECC memory is recommended in a server environment. Mixing
Non-ECC memory and ECC memory causes all ECC features to be disabled.
The controller automatically detects, sizes, and initializes the memory array, depending on the type,
size, and speed of the installed DIMMs, and reports memory size and allocation to the server via
configuration registers.
L440GX+ Server Board Product Guide 13
✏ NOTE
Use DIMMs that have been tested for compatibility with the server board.
Contact your sales representative or dealer for a current list of approved
memory modules. Check the Intel Customer Support website for the latest
tested memory list:
http://support.intel.com/support/motherboards/server/l440gx/compat.htm
440GX Host Bridge / Memory Controller
The Intel?? L440GX+ is designed around the Intel?? 82440GX AGPSet (440GX). This device
provides 100 MHz processor host bus interface support, DRAM controller, PCI bus interface, AGP
interface (used on L440GX+ for PCI-66/5V), and power management functions. The host
bus/memory interface in the 440GX is optimized for 100 MHz operation, using 100MHz SDRAM
main memory. The PCI interface is PCI 2.1-compliant, providing a 33 MHz / 5V signaling
environment for embedded controllers and slots in the single PCI segment on L440GX+. The
440GX memory controller supports up to 2 GB of ECC or Non-ECC memory, using PC/100
compliant Synchronous DRAM (SDRAM) devices on DIMM plug-in modules. ECC can detect
and correct single-bit errors, and detect multiple-bit errors.
Peripherals
Super I/O Chip
The National† 87309 device supports two serial ports, one parallel port, diskette drive,
PS/2-compatible keyboard and mouse. The server board provides a connector interface for
each port.
Serial Ports
Each serial port can be set to one of four different COMx ports and can be enabled separately.
When enabled, each port can be programmed to generate edge or level sensitive interrupts. When
disabled, serial port interrupts are available to add-in boards.
Parallel Port
The 87309 provides one IEEE 1284-compatible 25 pin bidirectional EPP (supporting levels 1.7
and 1.9). BIOS programming of the 87309 registers enable the parallel port and determine the port
address and interrupt. ECP mode is supported with 2 possible DMA channels. When disabled, the
interrupt is available to add-in boards.
14 Description

both slots will be lowered to 33 MHz.
The components on some full length cards installed in slot 6 may interfere
with the DIMM connector latches.
L440GX+ Server Board Product Guide 15
Video
The onboard, integrated Cirrus Logic CL-GD5480 64 bit VGA chip contains an SVGA controller
that is fully compatible with these video standards: CGA, EGA, Hercules† Graphics, MDA, and
VGA. The standard configuration comes with 2 MB of 10 ns onboard Synchronous Graphics
Memory (SGRAM). The video controller supports pixel resolutions of up to 1600 x 1200 and up to
16.7 Million colors.
The SVGA controller supports analog VGA monitors (single and multiple frequency, interlaced
and noninterlaced) with a maximum vertical retrace noninterlaced frequency of 100 Hz.
You cannot add video memory to the server board. Depending on the environment, the controller
displays up to 16.7 M colors in some video resolutions. It also provides hardware accelerated bit
block transfers (BITBLT) of data.
SCSI Controller
The embedded Adaptec AIC-7896 dual function SCSI controller provides both Ultra2 (LVDS)
wide and Ultra wide SCSI interfaces as two independent PCI functions. PCI slot 4 is
RAID-upgradeable, providing additional support for the ARO1130U2 RAIDport III controller by
Adaptec.
The SCSI bus is terminated on the server board with active terminators that cannot be disabled.
The onboard device must always be at one end of the bus. The device at the end of the cable must
be terminated. LVDS devices generally do not have termination capabilities. Non-LVDS devices
generally are terminated through a jumper or resistor pack. The SCSI cable (Intel Part Number
745854-003) included with your server board (or integrator’s kit) has been modified to include
active termination. The cable is capable of supporting both Ultra-2 and non-Ultra-2 SCSI devices.
Proper termination of the SCSI bus is required for stable operation of SCSI devices. When
attaching any SCSI device to the cable, verify that they are not terminated. This is usually a
configurable option using a jumper or terminator block on the device. Check the documentation
that came with your SCSI device to verify this option. Termination of the SCSI bus is implemented
using the active termination on the server board along with the active termination at the end of the
SCSI cable.
IDE Controller
IDE is a 16 bit interface for intelligent disk drives with disk controller electronics onboard. The
PCI/ISA/IDE Accelerator, also known as PIIX4e, is a multifunction device on the server board that
acts as a PCI based Fast IDE controller. The device controls:
• PIO and IDE DMA/bus master operations
• Mode 4 timings
• Transfer rates up to 33 MB/s
• Buffering for PCI/IDE burst transfers
• Master/slave IDE mode
• Up to two devices per channel; two channels, IDE0 and IDE1
16 Description
✏ NOTE
18 inch maximum length of IDE cable on each channel: You can connect
an IDE signal cable, up to a maximum of 18 inches each, to each
IDE connector on the server board. Each cable can support two devices, one
at the end of the cable and one 6 inches from the end of the cable.
Network Controller
The server board includes a 10BASE-T/100BASE-TX network solution based on the Intel 82559
single chip Fast Ethernet PCI Bus Controller. As a PCI bus master, the controller can burst data at
up to 132 MB/s. The controller contains two receive and transmit FIFO buffers that prevent data
overruns or underruns while waiting for access to the PCI bus. The controller has the following:
• 32 bit PCI bus master interface (direct drive of bus), compatible with PCI Bus Specification,
Revision 2.1
• Chained memory structure with improved dynamic transmit chaining for enhanced
performance
• Programmable transmit threshold for improved bus utilization
• Early receive interrupt for concurrent processing of receive data
• Onchip counters for network management
• Autodetect and autoswitching for 10 or 100 Mbps network speeds
• Support for both 10 Mbps and 100 Mbps networks, capable of full or half duplex, with back-toback
transmit at 100 Mbps
The network status LEDs on the server board indicate:
• Transmit/receive activity on the LAN
• Valid link to the LAN
• 10/100 Mbps transfer mode
Network Teaming Features
The network controller provides several options for increasing throughput and fault tolerance when
running Windows NT 4.0, Windows 2000 or NetWare 4.1x or newer:
• Adapter Fault Tolerance (AFT) - provides automatic redundancy for your adapter. If the
primary adapter fails, the secondary takes over. AFT works with any hub or switch.
• Adaptive Load Balancing (ALB) - creates a team of 2 - 4 adapters to increase transmission
throughput. Also includes AFT. Works with any 10Base-TX or 100Base-TX switch.
• Fast EtherChannel† (FEC) - creates a team of 2, 3 or 4 adapters to increase transmission and
reception throughput. Also includes AFT. Requires an FEC-enabled switch.
To set up an option, read the instructions in the Windows NT 4.0 or NetWare 4.1x readme files.
L440GX+ Server Board Product Guide 17
General Configuration Notes
1. Windows NT versions prior to 4.0 don’t support Adapter Teaming options.
2. Adapter Teaming options require NT 4.0 with Service Pack 4.0 or Service Pack 3.0 and Hotfix.
3. In Windows NT, teaming options cannot be implemented on adapters that have been
configured for VLANs. NetWare can support teaming options and VLANs on the same
adapters.
Adapter Fault Tolerance
Adapter Fault Tolerance (AFT) is a simple, effective, and fail-safe approach to increase the
reliability of server connections. AFT gives you the ability to set up link recovery to the server
adapter in case of a cable, port, or network interface card failure. By assigning two PRO/100
Intelligent Server adapters as a team, AFT enables you to maintain uninterrupted network
performance.
AFT is implemented with two PRO/100 Intelligent Server adapters: a primary adapter and a
backup, or secondary, adapter. During normal operation, the backup will have transmit disabled. If
the link to the primary adapter fails, the link to the backup adapter automatically takes over.
Preferred Primary Adapter
With multiple adapters installed, you can specify one as the Preferred Primary adapter. For
example if you have a server with a PRO/100 Intelligent Server adapter as the primary adapter and
a PRO/100+ adapter as the secondary, you would want the PRO/100 Intelligent Server adapter to be
the preferred primary. In this scenario, if the PRO/100 Intelligent Server adapter fails, the
PRO/100+ will take over. Then when the PRO/100 Intelligent Server adapter is replaced, it will
automatically revert to being the primary adapter in the team.
If a Preferred Primary is not selected, PROSet will attempt to select the best adapter, based on
adapter model and speed.
Mixed Adapter Teaming
AFT supports up to four PRO/1000 or PRO/100 adapters per team, in any mix.
Adaptive Load Balancing
Adaptive Load Balancing (ALB) is a simple and efficient way to increase your server’s transmit
throughput. With ALB you group PRO/100 Intelligent Server adapters in teams to provide an
increased transmit rate (up to 400 Mbps) using a maximum of four adapters. The ALB software
continuously analyzes transmit loading on each adapter and balances the rate across the adapters as
needed. Adapter teams configured for ALB also provide the benefits of AFT. Receive rates remain
at 100 Mbps.
To use ALB, you must have two, three, or four PRO/100 Intelligent Server adapters installed in
your server or workstation and linked to the same network switch.
18 Description
Cisco Fast EtherChannel
Fast EtherChannel (FEC) is a performance technology developed by Cisco to increase your server’s
throughput. Unlike ALB, FEC can be configured to increase both transmission and reception
channels between your server and switch. FEC works only with FEC-enabled switches, such as the
Catalyst 5000 series. With FEC, as you add adapters to your server, you can group them in teams
to provide up to 800 Mpbs at full duplex, with a maximum of four PRO/100 Intelligent Server
adapters. The FEC software continuously analyzes loading on each adapter and balances network
traffic across the adapters as needed. Adapter teams configured for FEC also provide the benefits
of AFT.
To use FEC, you must have two or four PRO/100 Intelligent Server adapters installed in your
server and linked to the same FEC-enabled Cisco switch.
Keyboard and Mouse
The keyboard/mouse controller is PS/2-compatible. The server may be locked automatically if
there is no keyboard or mouse activity for a predefined length of time, if specified through the
System Setup Utility (SSU). Once the inactivity (lockout) timer has expired, the keyboard and
mouse do not respond until the previously stored password is entered.
ACPI
The L440GX+ supports the Advanced Configuration and Power Interface (ACPI) as defined by the
ACPI 1.0 and PC97 specifications. An ACPI aware operating system can put the system into a
state where the hard drives spin down, the system fans stop, and all processing is halted. However,
the power supply will still be on and the processors will still be dissipating some power, so the
power supply fan and processor fans will still run.
The L440GX+ supports sleep states s0, s1, s4, and s5. With future versions of Microsoft†
Windows† 9X that support ACPI, the BIOS will only support sleep states s0, s1, and s5. With
future versions of Microsoft Windows NT†x that support ACPI, the BIOS will support sleep states
s0, s1, s4, and s5.
• s0: Normal running state.
• s1: Processor sleep state. No context will be lost in this state and the processor caches will
maintain coherency.
• s4: Hibernate or Save to Disk: The memory and machine state are saved to disk. Pressing the
power button or other wakeup event will restore the system state from the disk and resume
normal operation. This assumes that no hardware changes have been made to the system while
it was off.
• s5: Soft off: Only the RTC section of the PIIX4 and the BMC are running in this state.
CAUTION
The system is off only when the AC power is disconnected.
L440GX+ Server Board Product Guide 19
Server Management
Server Management features are implemented using one microcontroller.
Baseboard Management Controller (BMC)
All server management functionality is concentrated in the BMC. The BMC and associated
circuitry are powered from + 5V_Standby, which remains active when server power is switched off
and the server is still plugged into AC power.
One major function of the BMC is to autonomously monitor system management events, and log
their occurrence in the nonvolatile System Event Log (SEL). These include events such as
overtemperature and overvoltage conditions, fan failure, or chassis intrusion. To enable accurate
monitoring, the BMC maintains the nonvolatile Sensor Data Record (SDR), from which sensor
information can be retrieved. The BMC provides an ISA host interface to SDR sensor information,
so software running on the server can poll and retrieve the server’s current status.
SEL contents can be retrieved after system failure, for analysis by field service personnel using
server management software tools such as Intel?? Server Control available on the CD-ROM that
ships with the L440GX+ server board or from the Intel Customer Support website:
http//support.intel.com/support/motherboards/server/l440gx
Because the BMC is powered by 5V_Standby, SEL and SDR information are also available via the
IMB (Intelligent Management Bus). An Emergency Management Card, such as the
Intel?? LANDesk?? SMM (Server Monitor Module) card available with the LANDesk Server
Manager Pro package, can obtain the SEL and make it remotely accessible using a LAN or
telephone line connection. While it receives the proper current, the BMC does the following:
• Monitors server board temperature and voltage
• Monitors processor presence and controls FRB
• Detects and indicates baseboard fan failure
• Manages the SEL interface
• Manages the SDR Repository interface
• Monitors the SDR/SEL timestamp clock
• Manages the server board Field Replaceable Unit (FRU) information interface
• Monitors the system management watchdog timer
• Monitors the periodic SMI timer
• Manages front panel NMI handling
• Monitors the event receiver
• Manages the ISA host and IMB interface
• Controls secure mode, including video blanking, floppy write-protect monitoring, and front
panel lock/unlock initiation
• Manages the sensor event initialization agent
• Controls Wake on LAN via Magic Packet† support
20 Description
Emergency Management Port Console
The Emergency Management Port (EMP) Console provides an interface to the Emergency
Management Port (EMP). This interface allows remote server management via a modem or direct
(serial port to serial port) connection.
The server control operations available with EMP Console are:
• Connecting to remote servers
• Powering the server on or off
• Resetting the server
The EMP Console uses three management plug-ins to monitor the server:
• SEL Viewer
• SDR Viewer
• FRU Viewer
The EMP Console also has Phonebook plug-in that can be used to create and maintain a list of
servers and their phone numbers.
✏ NOTE
EMP and PEP (Platform Event Paging) share your modem. PEP has priority
over all applications except EMP. If an alert occurs, PEP will reset your
modem and page you.
✏ NOTE
EMP and Console redirection will not function properly while the BIOS
Setup option “POST Diagnostic Screen” is set to DISABLED. In order to
use EMP and Console Redirection, this option must be set to ENABLED.
Platform Event Paging
With Platform Event Paging (PEP), your server can be configured to automatically dial up a paging
service and page you when a platform event occurs. Platform events include temperature out-ofrange,
voltage out-of-range, chassis intrusion, fan failure, etc.
If PEP is enabled and the BMC receives or detects a new event, it automatically sends a page. It
can send a page if the processors are down or if the system software is unavailable.
PEP needs an external modem connected to the server's EMP (Emergency Management Port) serial
connection. This is typically the COM2 serial connector.
L440GX+ Server Board Product Guide 21
Security
To help prevent unauthorized entry or use of the server, Intel Server Control server management
software monitors the system intrusion switch.
Security with Mechanical Locks and Monitoring
If installed, you can activate the chassis intrusion alarm switch. When the side door is opened, the
switch transmits an alarm signal to the server board, where BMC firmware and server management
software process the signal. The system can be programmed to respond to an intrusion by
powering down or by locking the keyboard, for example.
Software Locks
The BIOS Setup and the System Setup Utility (SSU) provide a number of security features to
prevent unauthorized or accidental access to the system. Once the security measures are enabled,
you can access the system only after you enter the correct password(s). For example:
• Enable the keyboard lockout timer so that the server requires a password to reactivate the
keyboard and mouse after a specified time out period1 to 120 minutes.
• Set and enable an administrative password.
• Set and enable a user password.
• Set secure mode to prevent keyboard or mouse input and to prevent use of the front panel reset
and power switches.
• Activate a hot key combination to enter secure mode quickly.
• Disable writing to the diskette drive when secure mode is set.
• Disable access to the boot sector of the operating system hard disk drive.
Using Passwords
You can set either the user password, the administrator password, or both passwords. If only the
user password is set, you:
• Must enter the user password to enter BIOS Setup or the SSU.
• Must enter the user password to boot the server if Password on Boot is enabled in either the
BIOS Setup or SSU.
• Must enter the user password to exit secure mode.
If only the administrator password is set, you:
• Must enter the administrator password to enter BIOS Setup or the SSU.
• Must enter the administrator password to boot the server if Password on Boot is enabled in
either the BIOS Setup or SSU.
• Must enter the administrator password to exit secure mode.
If both passwords are set, you:
• May enter the user password to enter BIOS Setup or the SSU. However, you will not be able to
change many of the options.
• Must enter the administrator password if you want to enter BIOS Setup or the SSU and have
access to all of the options.
22 Description
• May enter either password to boot the server if Password on Boot is enabled in either the BIOS
Setup or SSU.
• May enter either password to exit secure mode.
Secure Mode
Configure and enable the secure boot mode by using the SSU. When secure mode is in effect:
• You can boot the server and the operating system will run, but you must enter the user
password to use the keyboard or mouse.
• You cannot turn off system power or reset the server from the front panel switches.
Secure mode has no effect on functions enabled via the Server Manager Module or power control
via the real time clock.
Taking the server out of secure mode does not change the state of system power. That is, if you
press and release the power switch while secure mode is in effect, the system will not be powered
off when secure mode is later removed. However, if the front panel power switch remains
depressed when secure mode is removed, the server will be powered off.
Summary of Software Security Features
The table below lists the software security features and describes what protection each offers. In
general, to enable or set the features listed here, you must run the SSU and go to the Security
Subsystem Group, menu. The table also refers to other SSU menus and to the Setup utility.
Table 3. Software Security Features
Feature Description
Secure mode How to enter secure mode:
• Setting and enabling passwords automatically places the system in secure
mode.
• If you set a hot-key combination (through the SSU or Setup), you can
secure the system simply by pressing the key combination. This means
you do not have to wait for the inactivity time-out period.
When the system is in secure mode:
The server can boot and run the operating system, but mouse and keyboard
input is not accepted until the user password is entered.
At boot time, if a CD is detected in the CD-ROM drive or a diskette in drive A,
the system prompts for a password. When the password is entered, the
server boots from CD or diskette and disables the secure mode.
If there is no CD in the CD-ROM drive or diskette in drive A, the server boots
from drive C and automatically goes into secure mode. All enabled secure
mode features go into effect at boot time.
To leave secure mode: Enter the correct password(s).
Disable writing to diskette In secure mode, the server will not boot from or write to a diskette unless a
password is entered. To set this feature, use the SSU Security Subsystem
Group.
To write protect access to diskette whether the server is in secure mode or
not, use the Setup main menu, Floppy Options, and specify Floppy Access as
read only.

Table 3. Software Security Features (continued)
Feature Description
Disable the power and
reset buttons
Enable the feature through the SSU. Then the power and reset buttons are
disabled when the server is in secure mode.
Set a time out period so
that keyboard and mouse
input are not accepted
Also, screen can be
blanked, and writes to
diskette can be inhibited
Specify and enable an inactivity time out period of from 1 to 120 minutes.
If no keyboard or mouse action occurs for the specified period, attempted
keyboard and mouse input will not be accepted.
The monitor display will go blank, and the diskette drive will be write protected
(if these security features are enabled through Setup or the SSU).
To resume activity: Enter the correct password(s).
Control access to using
the SSU: set
administrative password
To control access to setting or changing the system configuration, set an
administrative password and enable it through Setup or the SSU.
If both the administrative and user passwords are enabled, either can be used
to boot the server or enable the keyboard and/or mouse, but only the
administrative password will allow Setup and the SSU to be changed.
To disable a password, change it to a blank entry or press CTRL-D in the
Change Password menu of the Administrative Password Option menu found in
the Security Subsystem Group.
To clear the password if you cannot access Setup or the SSU, change the
Clear Password jumper (see Chapter 5).
Control access to the
system other than SSU:
set user password
To control access to using the system, set a user password and enable it
through Setup or the SSU.
To disable a password, change it to a blank entry or press CTRL-D in the
Change Password menu of the User Password Option menu found in the
Security Subsystem Group.
To clear the password if you cannot access Setup or the SSU, change the
Clear Password jumper (see Chapter 5).
Boot without keyboard The system can boot with or without a keyboard. During POST, before the
system completes the boot sequence, the BIOS automatically detects and
tests the keyboard if it is present and displays a message. There is no entry in
the SSU to enable or disable a keyboard.
Specify the boot sequence The sequence that you specify on the menu in the SSU MultiBoot Group will
determine the boot order. If secure mode is enabled (a user password is set),
then you will be prompted for a password before the server fully boots. If
secure mode is enabled and the “Secure Boot Mode” option is also enabled,
the server will fully boot but will require a password before accepting any
keyboard or mouse input.

2 Upgrading
Tools and Supplies Needed
• Phillips (cross head) screwdriver (#1 bit and #2 bit)
• Jumper removal tool or needle nosed pliers
• Pen or pencil
• Antistatic wrist strap and conductive foam pad (recommended)
Warnings and Cautions
These warnings and cautions apply throughout this chapter. Only a technically qualified person
should configure the server board.
WARNINGS
System power on/off: The power button DOES NOT turn off the
system AC power. To remove power from system, you must unplug the
AC power cord from the wall outlet. Make sure the AC power cord is
unplugged before you open the chassis, add, or remove any components.
Hazardous conditions, devices & cables: Hazardous electrical
conditions may be present on power, telephone, and communication
cables. Turn off the server and disconnect the power cord,
telecommunications systems, networks, and modems attached to the
server before opening it. Otherwise, personal injury or equipment
damage can result.
CAUTIONS
Electrostatic discharge (ESD) & ESD protection: ESD can damage
disk drives, boards, and other parts. We recommend that you perform all
procedures in this chapter only at an ESD workstation. If one is not
available, provide some ESD protection by wearing an antistatic wrist strap
attached to chassis groundany unpainted metal surfaceon your server
when handling parts.
ESD and handling boards: Always handle boards carefully. They can
be extremely sensitive to ESD. Hold boards only by their edges. After
removing a board from its protective wrapper or from the server, place the
board component side up on a grounded, static free surface. Use a
conductive foam pad if available but not the board wrapper. Do not slide
board over any surface.
26 Upgrading
Installing or removing jumpers: A jumper is a small plastic encased
conductor that slips over two jumper pins. Some jumpers have a small tab on
top that you can grip with your fingertips or with a pair of fine needle nosed
pliers. If your jumpers do not have such a tab, take care when using needle
nosed pliers to remove or install a jumper; grip the narrow sides of the
jumper with the pliers, never the wide sides. Gripping the wide sides can
damage the contacts inside the jumper, causing intermittent problems with
the function controlled by that jumper. Take care to grip with, but not
squeeze, the pliers or other tool you use to remove a jumper, or you may
bend or break the stake pins on the board.
Server Board
Installing the Server Board
CAUTION
The server board can be extremely sensitive to ESD and always requires
careful handling. After removing it from the server, place it component side
up on a nonconductive, static free surface to prevent shorting out the battery
leads. If you place the board on a conductive surface, the battery leads may
short out. If they do, this will result in a loss of CMOS data and will drain
the battery. Do not slide the server board over any surface.
1. Observe the safety and ESD precautions at the beginning of this chapter.
2. Insert screws through the mounting holes and into the threaded standoffs. Make sure the board
is properly seated, and then tighten all the screws firmly.
3. Connect all internal cables to the server board.
✏ NOTE
The floppy cable (Intel Part Number 738992-002) has been modified to
support all floppy drives. The floppy drive connector on the cable (see
connector label) is not keyed. Care should be taken to match pin 1 of the
cable, indicated with a red stripe on the cable, with pin 1 of the floppy drive.
4. Reinstall add-in boards.
5. Connect all internal cables to add-in boards. Make sure you connect the power cables to the
correct power connectors.
6. Connect all peripheral device cables to the I/O panel on the rear of the server.
7. Run the SSU to configure the server.

Memory
Installing DIMMs
CAUTIONS
Use extreme care when installing a DIMM. Applying too much pressure can
damage the socket. DIMMs are keyed and can be inserted in only one way.
Mixing dissimilar metals may cause later memory failures resulting in data
corruption. Only install DIMMs with gold-plated edge connectors in
gold-plated sockets.
See Chapter 1 for memory size and requirements.
1. Observe the safety and ESD precautions at the beginning of this chapter.
2. Open your server.
3. Holding the DIMM only by its edges, remove it from its antistatic package.
4. Orient the DIMM so that the two notches in the bottom edge of the DIMM align with the keyed
socket.
5. Insert the bottom edge of the DIMM into the socket, and press down firmly on the DIMM until
it seats correctly.
6. Gently push the plastic ejector levers on the socket ends to the upright position.
7. Repeat the steps to install each DIMM.
8. Close the server.
9. Connect all external cables and the power cord to the server.
10. Turn on the monitor and then the server.

Grounded Retention Mechanisms (GRMs)
The processor Grounded Retention Mechanisms are not compatible with SECC type processor
packaging. GRMs only support SECC2 type processors. If you plan to use SECC type processors,
you must use the Universal Retention Mechanism (URM). URMs can be ordered through your
distributor.
Installing the Grounded Retention Mechanisms
1. Install the GRMs in the server board before installing the board in the chassis.
2. Place the server board on a soft, nonconductive surface. If you place the board on a hard
surface, the grommets and pins will not go through far enough to seat properly.
3. The GRMs are color-coded white and black. The white GRM is installed closest to the edge of
the server board (G).
4. Orient the white GRM (A) so the grommets (E) line up with the holes in the server board. The
white GRM is slotted (B) to match the key (C) on the processor connector. Properly installed
retention mechanisms are seated firmly (no movement) and flush with the server board.
5. Press the pins (D) so they are flush with the grommets.
6. Repeat the procedure for the black GRMs (F).
