Chapter 1: Product Introduction
13. Front panel audio header
This header is for a chassis-mounted front panel audio I/O module that
supports HD audio standard. Connect one end of the front panel audio
I/O module cable to this header.
• We recommend that you connect a high-denition front panel
audio module to this header to avail of the motherboard’s high-
denition audio capability.
• If you want to connect a high-denition front panel audio
module to this header, set the Front Panel Type item in the
BIOS setup to [HD Audio]. By default, this header is set to [HD
Audio].
14. LPC Debug header
This header allows connection to a LPC Debug card.
• Scan the QR code to view the meaning of
each debugging code.
• Debugging codes are only available for
ASUS LPC Debug cards.
• Contact your region sales representative
for LPC Debug cards ordering.
15. LPT header
The LPT (Line Printing Terminal) header supports devices
such as a printer. LPT standardizes as IEEE 1284, which is the parallel port
interface on IBM PC-compatible computers.
16. Speaker header
The 4-pin header is for the chassis-mounted system warning speaker. The
speaker allows you to hear system beeps and warnings.
17. 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 helps enhance
network security, protects digital identities, and ensures platform integrity.
18. 10-1 pin System Panel header
This header supports several chassis-mounted functions.
• System power LED (2-pin +PWR_LED-)
This 2-pin header is for the system power LED. Connect the chassis power LED cable
to this header. The system power LED lights up when you turn on the system power,
and blinks when the system is in sleep mode.
