Chassis Intrusion Switch Connector
Function: Connector for Chassis intrusion switch.
Description: The hardware monitor subsystem supports
a chassis security feature that detects if the chassis (sys-
tem housing) cover is removed. When the cover is re-
moved, a signal is sent to the hardware monitor compo-
nent. The chassis intrusion circuit is powered by the sys-
tem power supply when the computer is connected to
AC power or by the onboard battery when it is not.
This feature uses a mechanical switch on the chassis that
connects to the chassis intrusion connector on the
motherboard. When the chassis cover is removed the
motherboard circuitry will detect the intrusion.
More Information: See the “System Features” section in
Chapter 6.
