11.Chassis Intrusion Alarm Lead (4-1 pin CHASIS)

This requires an external detection mechanism such as a chassis intrusion moni- tor/sensor or microswitch. The sensor is triggered when a high level signal is sent to the CHASIS lead. This occurs when the side panel is opened or drive bay doors are opened.

NOTE: When the chassis is opened, connect/short the Chassis Signal pin to the +5VSB pin. When the chassis is closed, connect/short the Chassis Signal pin to the Ground pin.
