2-38 Chapter 2: Hardware information
11. Chassis intrusion connector (4-1 pin CHASSIS)
This connector is for a chassis-mounted intrusion detection sensor or switch.
Connect one end of the chassis intrusion sensor or switch cable to this
connector. The chassis intrusion sensor or switch sends a high-level signal to
this connector when a chassis component is removed or replaced. The signal
is then generated as a chassis intrusion event.
By default, the pins labeled “Chassis Signal” and “Ground” are shorted with
a jumper cap. Remove the jumper caps only when you intend to use the
chassis intrusion detection feature.
12. CPU, Chassis, and Power Fan connectors (4-pin CPU_FAN, 3-pin
PWR_FAN1, 3-pin PWR_FAN2, 3-pin CHA_FAN1, 3-pin CHA_FAN2)
The fan connectors support cooling fans of 2A (24W max.) at +12V. Connect
the fan cables to the fan connectors on the motherboard, making sure that
the black wire of each cable matches the ground pin of the connector.
