System Panel header The System Panel 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. 1-6 Chapter 1: Product Introduction

16. 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 certificates, passwords and data. A
TPM system also enhances network security, protects digital
identities, and ensures platform integrity.
The TPM module is purchased separately.
17. System Panel header
The System Panel 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.
