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.

DO NOT forget to connect the fan cables to the fan connectors. Insufficient air flow inside

the system may damage the motherboard components. They are not jumpers! DO NOT

place jumper caps on the fan connectors.

5.

Chassis intrusion connector (4-1 pin CHASSIS)
This connector is for a chassis-mounted intrusion detection sensor or switch. 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 pin 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.
