III. HARDWARE SETUP
27. Chassis Intrusion Sensor Lead (4-1 pin CHASIS)
This lead is for a chassis intrusion monitor or sensor. The sensor is triggered
when a high level signal is sent to the "chassis signal" lead. This occurs when a
panel switch or light detector is triggered. This function requires the optional
ASUS CIDB Chassis Sensor to be installed.

The ASUS CIDB Chassis Sensor
The optional ASUS CIDB is a module for providing audio alarm and logging when
there is an intrusion into the chassis of a computer system. The module detects a chas-
sis intrusion by either light striking its photo sensor or by contact when its switch
connectors are shorted by chassis-mounted momentary toggle switches. An intrusion
memory function allows detection by BIOS and LDCM on the next bootup.
