• System Power LED header (PLED)
The 2-pin header allows you to connect the System Power LED. The System Power
LED lights up when the system is connected to a power source, or when you turn on
the system power, and blinks when the system is in sleep mode.
• Storage Device Activity LED header (HDD_LED)
The 2-pin header allows you to connect the Storage Device Activity LED. The Storage
Device Activity LED lights up or blinks when data is read from or written to the storage
device or storage device add-on card.
• System Warning Speaker header (SPEAKER)
The 4-pin header allows you to connect the chassis-mounted system warning
speaker. The speaker allows you to hear system beeps and warnings.
• Power Button/Soft-off Button header (PWRSW)
The 3-1 pin header allows you to connect the system power button. Press the
power button to power up the system, or put the system into sleep or soft-off mode
(depending on the operating system settings).
• Reset button header (RESET)
The 2-pin header allows you to connect the chassis-mounted reset button. Press the
reset button to reboot the system.
• Chassis intrusion header (2-pin CHASSIS)
This header is for a chassis-mounted intrusion detection sensor or switch. Connect
one end of the chassis intrusion sensor or switch cable to this header. 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.
