•Alert on LAN functionality
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.

Description 9
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.

10 Intel Server Board SDS2 Product Guide
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 SDS2 supports the Advanced Configuration and Power Interface (ACPI) as defined by the
ACPI 1.0b. 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 SDS2 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 chipset and the BMC are running in this state.
CAUTION
The system is off only when the AC power is disconnected.
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 locking
the keyboard, for example.

Description 11
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 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.
•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.

12 Intel Server Board SDS2 Product Guide
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
Securemode 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 pressingthe 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.

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.
Specify the boot sequence 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.
