Chassis Intrusion and Detection
The Intel Server Board S875WP1-E supports a chassis security feature that detects if the
chassis cover is removed. For the chassis intrusion circuit to function, the chassis’ power supply
must be connected to AC power. 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 closed position.

NOTE
Chassis intrusion detection may be implemented using LANDesk* Client Manager or other third-
party software.
3.6 Power
Management
Power management is implemented at several levels, including:
10
Software support through Advanced Configuration and Power Interface (ACPI)
11 Hardware
support:
Power connector
Fan connectors
LAN wake capabilities
Instantly Available PC technology
Wake from USB
Wake from PS/2 devices
Power Management Event (PME#) wake-up 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 Intel Server Board S875WP1-E requires an
operating system that provides full ACPI support. ACPI features include:
12
Plug and Play (including bus and device enumeration)
13
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
14
Methods for achieving less than 15-watt system operation in the standby or
sleeping state
15
A Soft-off feature that enables the operating system to power-off the computer
16
Support for multiple wake-up events (see Table 7)
•
Support for a front panel power and sleep mode switch
