Chassis signal
Ground
The system board supports the chassis intrusion detection function.
Connect the chassis intrusion sensor cable from the chassis to J1.
Whenever a chassis component has been removed, the sensor
sends signal to J1 alerting you of a chassis intrusion event.
Hardware Monitor for Windows
The Hardware Monitor for Windows utility allows you to enable the
chassis intrusion detection function. By default, the function is disabled.
When enabled, a warning message will appear when the chassis is
open. The utility can also be configured so that a beeping alarm will
sound when the chassis is open. Refer to the "Hardware Monitor for
Windows" section in chapter 4 for more information.
