17. System Panel header
This header supports several chassis-mounted functions.
•
System Power LED header (PLED)
The 2-pin and/or 3-1 pin headers allow 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 2-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 (CHASSIS)
The 2-pin header allows you to connect the chassis-mounted intrusion detection
sensor or switch. The chassis intrusion sensor or switch sends a high-level signal
to the header when a chassis component is removed or replaced, the signal is then
generated as a chassis intrusion event.
18. Q-LEDs
The Q-LEDs check key components (CPU, DRAM, VGA, and booting devices) during the
motherboard booting process. If an error is found, the critical component's LED stays lit up
until the problem is solved.
The Q-LEDs provide the most probable cause of an error code as a starting point for
troubleshooting. The actual cause may vary from case to case.
