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 intru-
sion occurred, the alarm will sound only when the system restarts.

Power Connectors
Use a power supply that complies with the ATX12V Power Supply Design Guide Version 1.1.
An ATX12V power supply unit has a standard 4-pin ATX main power connector that must be
inserted into the 4-pin connector.
The power connector from the power supply unit are designed to fit the 4-pin connector in
only one orientation. Make sure to find the proper orientation before plugging the connectors.
The system board requires a minimum of 300 Watt power supply to operate. Your system
configuration (CPU power, amount of memory, add-in cards, peripherals, etc.) may exceed the
minimum power requirement. To ensure that adequate power is provided, we strongly recom-
mend that you use a minimum of 400 Watt (or greater) power supply.
Important:
Insufficient power supplied to the system may result in instability or the add-in boards
and peripherals not functioning properly. Calculating the system’s approximate power
usage is important to ensure that the power supply meets the system’s consumption
requirements.
