Intel SE7221BA1 Product Specification - Page 26

Functional Architecture Intel® Entry Server Board SE7221BA1-E TPS 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 Management Power management is implemented at several levels, including: • Software support through Advanced Configuration and Power Interface (ACPI) • Hardware support: ⎯ Power connector ⎯ Fan connectors ⎯ LAN wake capabilities ⎯ 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 16 Revision 1.5
