Chapter 1 Hardware Configuration 3
1.2 Features
1. Fan status monitoring and alarm: To prevent system overheating
and damage, the CPU fan can be monitored for speed and failure.
The fan is set for its normal RPM range and alarm thresholds.
2. Temperature monitoring and alert: To prevent system overheating
and damage, the CPU card supports processor thermal sensing and
auto-protection.
3. Voltage monitoring and alert: System voltage levels are monitored
to ensure stable current flows to critical components. Voltage
specifications will become even more critical for processors of the
future. Thus monitoring will become ever more necessary to ensure
proper system configuration and management.
4. ATX soft power switch: Through the BIOS, the power button can
be defined as the "Standby" (aka "Suspend" or "Sleep") button or
as the "Soft-Off" button (see Section 3.6.6 Soft-off by PWR-BTN).
Regardless of the setting, pushing the power button for more than
4 seconds will enter the Soft-Off mode.
5. Power-on by modem (requires modem): This allows a computer
to be turned on remotely through an internal or external modem.
Users can thus access information on their computers from
anywhere in the world.
6. Remote wake-up: This feature (aka "Wake-on-LAN") allows you
to remotely power up your system through your network by
sending a wake-up frame or signal. With this feature, you can
remotely upload/download data to/from systems during off-peak
hours.
7. Message LED: Chassis LEDs now act as information providers.
The way a particular LED illuminates indicates the stage the
computer is in. A single glimpse provides useful information to the
user.
8. Jumperless mode: When enabled, this allows changes of
