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.
