Chassis Intrusion Connector
The board supports the chassis intrusion detection function. Connect the chassis intrusion
sensor cable from the chassis to this connector. When the system’s power is on and a chassis
intrusion occurred, an alarm will sound. When the system’s power is off and a chassis intrusion
occurred, the alarm will sound only when the system restarts.
MyGuard Hardware Monitor
Install the “MyGuard Hardware Monitor” utility. By default, the chassis intrusion detection func-
tion 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 “MyGuard Hardware Monitor” section in chapter 4 for more information.
