Processor
The SCB2 accommodates one or two Intel Pentium III processors with 512k cache in the FC-PGA2
package. This processor uses the .13 micron technology and offers advanced performance. The
processor external interface operates at a maximum of 133 MHz. For a complete list of supported
processors see:
http://support.intel.com/support/motherboards/server/scb2
Memory
The system board contains six 168-pin DIMM slots each supporting 72-bit ECC (64-bit main
memory plus ECC) registered SDRAM DIMMs (PC-133 compatible). Memory is two-way
interleaved and partitioned in three banks. You may install a minimum of 128 MB (64MB x 2) and
as much as 6 GB.
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/scb2
PCI Riser Slots
The server board has two PCI riser slots, each capable of supporting 64-bit/66-MH z PCI riser cards.
PCI features:
• Bus speed up to 66 MHz
• 32 bit memory addressing
• 5 V/3.3 V signaling environment
• Burst transfers of up to 512 Mbps
• 8, 16, 32, or 64-bit data transfers
• Plug and Play ready

Video
The SCB2 uses an ATI RAGE XL PCI graphics accelerator with 8 MB of video SDRAM that
†
supports all standard IBM
• Pixel resolutions up to 1600 x 1200 under 2D and 1024 x 768 under 3D
• CRT and LCD monitors up to 100 Hz vertical refresh rate
The server board supports disabling of the onboard video through the BIOS setup menu or when a
plug in video card is installed in any of the PCI slots.
VGA modes. The embedded SVGA video subsystem supports:
SCSI Controller
The SCSI version of the server board includes an embedded Adaptec† AIC-7899W controller
providing dual Ultra160 Low Voltage Differential (LVD) SCSI channels.
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 other end of the cable
must also be terminated. LVD devices generally do not have termination built-in and need to have
a termination source provided. Non-LVDs devices generally are terminated through a jumper or
resistor pack on the device itself.
ATA-100 Controller
The ATA version of the server board provides an embedded dual channel ATA-100 bus through the
use of the Promise Technology
independent ATA-100 channels that share a single 32-bit, 33-MHz PCI bus master interface as a
multifunction device. The controller supports:
• DMA and PIO IDE drives and ATAPI devices
• ATA and ATAPI proposal PIO Mode 0, 1, 2, 3, 4; DMA Mode 0, 1, 2; and
Ultra DMA Mode 0, 1, 2, 3, 4, 5
• IDE transfer rates up to 100 MB/sec per channel
• Buffering for PCI/IDE burst transfers
• Master/slave IDE mode
• Host interface complies with PCI Local Bus Specification Revision 2.2

PDC20267 ATA-100 controller. The controller contains two
IDE RAID
The ATA-100 controller supports IDE RAID through both ATA-100 channels. In a RAID
configuration, multiple IDE hard drives are placed into one or more arrays of disks. Each array is
seen as an independent disk, though the array may include one, two, three, or four drives. The IDE
RAID can be configured as follows:
• RAID 0: Striping one to four drives
• RAID 1: Mirroring two drives
• RAID 1 +: Spare drive (three drives)
• RAID 0 +: One to four drives are required
Description 11
RAID 0 configurations are used for high performance applications, as it doubles the sustained
transfer rate of its drives. RAID 1 configurations are primarily used for data protection. It creates an
identical drive backup to a secondary drive. Whenever a disk write is performed, the controller
sends data simultaneously to a second drive located on a different data channel. With 4 drives
attached to dual ATA-100 channels, two striped drive pairs can mirror each other (RAID 0+1) for
storage capacity and data redundancy.
Network Controller
NOTE
✏
To ensure EMC product regulation compliance, the system must be used
with a shielded LAN cable.
The server board uses two Intel
10Base-T/100Base-TX network subsystems.
The 82550 PM controller supports the following features:
• 32-bit PCI, CardBus master interface
• Integrated IEEE 802.3 10Base-T and 100Base-TX compatible PHY
• IEEE 820.3u auto-negotiation support
• Chained memory structure similar to the 82559, 82558, 82557 and 82596
• Full duplex support at both 10 Mbps and 100 Mbps operation
• Low power +3.3 V device
• IP checksum off-loading

On the SCB2, NIC 1 can be used as both a network interface and server management interface.
NIC Connector and Status LEDs
The 82550 controller drives LEDs on the network interface connector that indicate link/activity on
the LAN and 10- or 100-Mbps operation. The green LED indicates network connection when on
and TX/RX activity when blinking. The yellow LED indicates 100-Mbps operation when lit.
Network Teaming Features
NOTE
✏
Using both on-board NICs in a team does not allow the use of NIC 1 for
server management access. To support both network teaming features and
server management features, a third NIC must be added and teamed to NIC 2.
12 Intel Server Board SCB2 Product Guide
The network controller provides several options for increasing throughput and fault tolerance when
running Windows NT
†
4.0, Windows† 2000 , NetWare† 4.1x or newer, or Linux†:
• 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 - 8 adapters to increase transmission
throughput. Also includes AFT. Works with any 10Base-TX or 100Base-TX switch.
†
• Fast EtherChannel
(FEC) or Intel® Link Aggregation - creates a team of up to 8 adapters to
increase transmission and reception throughput. Also includes AFT. Requires a FEC-enabled
switch.
To set up an option, read the instructions in the Windows NT 4.0 or NetWare 4.1x readme files.
General Configuration Notes
1. Windows NT versions prior to 4.0 do not support Adapter Teaming options.
2. Adapter Teaming options require NT 4.0 with Service Pack 4.0 or Service Pack 3.0 and the
†
Windows Hot Fix
.
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 server adapters
as a team, AFT enables you to maintain uninterrupted network performance.
AFT is implemented with two 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/1000 server adapter as the primary adapter and a
PRO/100+ adapter as the secondary, you could configure the PRO/1000 server adapter to be the
preferred primary. In this scenario, if the PRO/1000 server adapter fails, the PRO/100+ will take
over. Then when the PRO/1000 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 eight server adapters per team, in any mix.
Description 13
Adaptive Load Balancing
Adaptive Load Balancing (ALB) is a simple and efficient way to increase your server’s transmit
throughput. With ALB you group server adapters in teams to provide an increased transmit rate
(up to 8 Gbps) using a maximum of eight 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 or
1 Gbps depending on the primary adapter’s capability.
To use ALB, you must have 2-8 server adapters installed in your server or workstation and linked
to the same network switch.
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 18 Gbps at full duplex, with a maximum of 8 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 2, 4, or 8 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. If specified through the System Setup Utility
(SSU), the server may be locked automatically if there is no keyboard or mouse activity for a
predefined length of time. Once the inactivity (lockout) timer has expired, the keyboard and mouse
do not respond until the previously stored password is entered. A Y-cable can be used if both a
PS/2 mouse and keyboard are required at the same time.
RJ-45 Serial Port
The rear RJ-45 serial port is a fully functional COM port that supports any standard serial device
and provides support for serial concentrators, which typically support RJ45 serial connectors. For
server applications that use a serial concentrator to access the server management features of the
baseboard, a standard 8-pin CAT-5 cable from the serial concentrator is plugged directly into the
rear RJ45 serial port. The 8 pins of the RJ45 connector can be configured to match either of two
pin-out standards used by serial port concentrators. To accommodate either standard, the
J6A2 jumper block located directly behind the rear RJ45 serial port must be jumpered appropriately
according to which standard is desired.
14 Intel Server Board SCB2 Product Guide
NOTE
✏
By default, as configured in the factory, the SCB2 baseboard will have the
rear RJ45 serial port configured to support a DSR signal.
For serial concentrators that require a DCD signal, the J6A2 jumper block must be configured as
follows: The DCD jumper in position 2 and 3 and the DSR jumper in position 2 and 3. Pin 1 on the
jumper is denoted by an arrow directly next to the jumper block. See Figure 3 on page 15 for the
jumper block pin-out of this configuration.
DSR to Pin#7
DCD to Pin#7
Figure 3. J6A2 Jumper Block for DCD Signal
For serial concentrators that require a DSR signal, the J6A2 jumper block must be configured as
follows: The DSR jumper in position 1 and 2 and the DCD jumper in position 1 and 2. Pin 1 on the
jumper is denoted by an arrow directly next to the jumper block. See Figure 4.
Figure 4. J6A2 Jumper Block for DSR Signal
DSR to Pin#7
DCD to Pin#7
For those server applications that require a DB9 type of serial connector, an 8-pin RJ45-to-DB9
adapter must be used. The following table defines the pin-out required for the adapter to provide
RS232 support.

Description 15
✏ NOTE
The RJ45-to-DB9 adapter should match the configuration of the serial device
used. One of two pin-out configurations are used depending on whether the
serial device requires a DSR or DCD signal. The final adapter configuration
should also match the desired pin-out of the RJ45 connector, as it can also be
configured to support either DSR or DCD.
For systems configured with both a front and rear RJ45 serial connectors, the
adapters used for the rear port cannot be used with the front port, as the pinout for both RJ45 ports are different. For example, modem applications
typically use DCD. In this case the user would use a DCD-configured adapter
and set the jumper block as shown in Figure 3.
ACPI
The SCB2 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 fans will still run.
The SCB2 supports 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 CSB and the BMC are running in this state. No
context is saved by the OS or hardware.
CAUTION
The system is off only when the AC power cord is disconnected.

software monitors the chassis intrusion switch if one is installed. Opening an access cover will
transmit an alarm signal to the server board, where BMC firmware and server management
software process the signal. The system can be configured through ISC to respond to an intrusion a
number of ways, including powering down or locking the keyboard.
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 a 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.
Description 17
• Must enter the supervisor password if you want to enter BIOS Setup or the SSU and have
access to all of the options.
• 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 remote server management or power control
via the watchdog timer.
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 4. 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 secu re 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.

To control access to setting or changing the system configuration, set a supervisor
password and enable it through Setup.
If both the supervisor and user passwords are enabled, either can be used to boot
the server or enable the keyboard and/or mouse, but only the supervisor password
will allow Setup to be changed.
To disable a password, change it to a blank entry or press CTRL-D in the Change
Password menu of the Supervisor Password Option menu found in the Security
Subsystem Group.
To clear the password if you cannot access Setup, change the Clear Password
jumper (see Chapter 5).
To control access to using the system, set a user password and enable it through
Setup.
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, change the Clear Password
jumper (see Chapter 5).
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.
The sequence that you specify in setup 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 Installation Procedures
Install the I/O Shield
NOTE
✏
An ATX 2.03-compliant I/O shield is provided with the server board. The
shield is required by Electromagnetic Interference (EMI) regulations to
minimize EMI. If the shield does not fit the chassis, obtain a properly sized
shield from the chassis supplier. The I/O shield does not support the use of
the USB 2 connector.
The shield fits the rectangular opening in the back of a chassis. The shield has cutouts that match
the I/O ports.
1. Install the shield from inside the chassis. Orient the shield so that the cutouts align with the
corresponding I/O connectors on the server board. Make sure the metal fingers are on the
inside of the chassis.
2. Position one edge (A) so that the dotted groove is outside the chassis wall, and the lip of the
shield rests on the inner chassis wall.
3. Hold the shield in place, and push it into the opening (B) until it is seated. Make sure the
I/O shield snaps into place all the way around.
