Processor
The STL2 server board accommodates one or two Intel Pentium III processors for the PGA370
socket. This processor uses the same core and offers the same performance as the Intel Pentium III
processor for the slot 2 connector, but utilizes a new package technology called flip chip pin grid
array, or FC-PGA. The processor external interface operates at a maximum of 133 MHz.
Memory
The system board contains four 168-pin DIMM sockets. Memory is partitioned as four banks of
registered SDRAM DIMMs (PC133 compatible), each providing 72 bits of noninterleaved memory
(64-bit main memory plus ECC).
Memory should be added in order from slot 1 to slot 4.
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.
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/STL2/compat.htm
10 Intel Server Board STL2 Product Guide

three slots will be lowered to 33 MHz.
Description 11
Video
The system has an integrated ATI Rage IIC 64 bit high-performance SVGA subsystem that
supports the following:
• BIOS compatibility with VGA, EGA, CGA, Hercules Graphics, and MDA
• 4 MB of 10 ns onboard Synchronous Graphics Memory (SGRAM)
• Pixel resolutions up to 1280 X 1024
• Analog VGA monitors (single and multiple frequency, interlaced and noninterlaced) with a
maximum vertical retrace noninterlaced frequency of 100 Hz.
SCSI Controller
The embedded Adaptec AIC-7899 dual function SCSI controller provides both Ultra160 (LVDS)
and Ultra wide (SE) SCSI interfaces as two independent PCI functions.
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 jumpe r or resis tor pack.
IDE Controller
The system includes a single channel enhanced IDE 32 bit interface controller for intelligent disk
drives with disk controller electronics onboard. The controller has a connector located on the
system board that supports a master and a slave device.
The device controls:
• PIO and DMA transfer modes
• DMA-33 capable
• Mode 4 timings
• Transfer rates up to 33 MB/s
• Buffering for PCI/IDE burst transfers
• Master/slave IDE mode
• Up to two devices.
12 Intel Server Board STL2 Product Guide
Network Controller
NOTE
✏
To ensure EMC product regulation compliance, the end system must be used
with a shielded LAN cable.
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-to-
back transmit at 100 Mbps
Network Teaming Features
The network controller provides several options for increasing throughput and fault tolerance when
running Windows NT
• 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
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.

Description 13
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 adapte r auto mat ica lly takes ove r.
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.
14 Intel Server Board STL2 Product Guide
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 STL2 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 STL2 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 NTx 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.
Description 15
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 period1 to 120 minutes.
• Set and enable an supervisor 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 supervisor 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 supervisor password is set, you:
• Must enter the supervisor password to enter BIOS Setup or the SSU.
• Must enter the supervisor password to boot the server if Password on Boot is enabled in either
the BIOS Setup or SSU.
• Must enter the supervisor 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 supervisor password if you want to enter BIOS Setup or the SSU and have
access to all of the options.
16 Intel Server Board STL2 Product Guide
• 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 2. 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 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 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.

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)
Cautions
These warnings and cautions apply throughout this chapter. Only a technically qualified person
should configure the server board.
CAUTIONS
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.
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 groundany unpainted metal surfaceon 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.
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
19
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.
Memory
Only PC133-compliant SDRAM is supported by the server board. Install from 64 MB to 4 GB of
registered memory, using up to four single- or double-banked DIMMs.
DIMMs must be installed in order from slot 1 to slot 4, no empty slots between installed DIMMs.
Slot 1 is the slot farthest from the processors.
Installed DIMMs must be the same speed and must all be registered. For a list of supported
memory, call your service representative or visit the Intel Support website:

Processors
WARNING
If the server has been running, any installed processor and heat sink on
the processor board(s) will be hot. To avoid the possibility of a burn, be
careful when removing or installing server board components that are
located near processors.
CAUTIONS
Processor must be appropriate: You may damage the server if you
install a processor that is inappropriate for your server. Make sure your
server can handle a newer, faster processor (thermal and power
considerations). For exact information about processor interchangeability,
contact your customer service representative or visit the Intel Customer
Support website:
http://support.intel.com/support/motherboards/server/STL2
ESD and handling processors: Reduce the risk of electrostatic
discharge (ESD) damage to the processor by doing the following: (1) Touch
the metal chassis before touching the processor or server board. Keep part of
your body in contact with the metal chassis to dissipate the static charge
while handling the processor. (2) Avoid moving around unnecessarily.

Adding or Replacing a Processor
If you are adding a second processor to your system, you must first remove the terminator from the
secondary processor socket. The second processor must be compatible with the first processor
(within one stepping, same voltage, same speed, see the Intel support website for specifics).
1. Observe the safety and ESD precautions at the beginning of this chapter and the additional
cautions given here.
2. Remove the side cover (see your system or chassis documentation for instructions).
3. Raise the locking bar on the socket.

Figure 4. Raise the Locking Bar
4. Aligning the pins of the processor with the socket, insert the processor into the socket. Note
what the processor speed is so you can set the jumpers correctly.
