17. Speaker header
The 4-pin header is for the chassis-mounted system warning speaker. The
speaker allows you to hear system beeps and warnings.
18. SPI TPM header
This header supports a Trusted Platform Module (TPM) system
with a Serial Peripheral Interface (SPI), allowing you to
securely store keys, digital certicates, passwords and data. A
TPM system also enhances network security, protects digital
identities, and ensures platform integrity.
The TPM module is purchased separately.
19. 10-1 pin System Panel header
This header supports several chassis-mounted functions.
• System Power LED header (+PWR_LED-)
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.
• Power Button/Soft-off Button header (PWR_BTN)
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.
