TPM Header
This header is used to connect a
Trusted Platform Module (TPM), which
is available from a third-party vendor. A
TPM is a security device that supports
encryption and authentication in hard
drives. It enables the motherboard to
deny access if the TPM associated
with the hard drive is not installed in
the system. See the table on the right
for pin definitions.
Overheat/Fan Fail LED
The JOH1 header is used to connect
an LED to provide warnings of chassis
overheat. This LED will also blink to
indicate a fan failure. Refer to the table
on right for pin definitions.
Speaker (JD1)
On the JD1 header, pins 4-7 are used
for internal speaker. Close pins 4-7
with a cap to use the speaker. See the
table on the right for pin definitions.
Internal Buzzer (SP1)
The Internal Buzzer (SP1) can be used
to provide audible indications for various
beep codes. See the table on the right for
pin definitions.
