Revision
1.5
3.5.3 Fan
Monitoring
Fan monitoring can be implemented using Intel Server Utilities, Intel Server Management
Software or third-party software. The level of monitoring and control is dependent on the
hardware monitoring ASIC used with the Server Board.
3.5.4
Chassis Intrusion and Detection
The Intel® Entry Server Board SE7221BA1-E supports a chassis security feature that detects if
the chassis cover is removed. The security feature uses a mechanical switch on the chassis
that attaches to the chassis intrusion connector. When the chassis cover is removed, the
mechanical switch is in the open position.
3.6 Power

⎯
Instantly Available PC technology
⎯
Resume on Ring
⎯
Wake from USB
⎯
Wake from PS/2 devices
⎯
Power Management Event signal (PME#) wake-up support
⎯
PCI Express* WAKE# signal support
3.6.1
Advanced Configuration and Power Interface (ACPI)
ACPI gives the operating system direct control over the power management and Plug and Play
functions of a computer. The use of ACPI with the SE7221BA1-E server board requires an
operating system that provides full ACPI support. ACPI features include:
•
Plug and Play (including bus and device enumeration)
•
Power management control of individual devices, add-in boards (some add-in boards
may require an ACPI-aware driver), video displays, and hard disk drives
•
Methods for achieving less than 15-watt system operation in the power-on/standby
sleeping state
•
A Soft-off feature that enables the operating system to power-off the computer
•
Support for multiple wake-up events (see Table 4. Wake-up Devices and Events)
•
Support for a front panel power and sleep mode switch
