Intruder Alert and Speaker Headers
Both of the 2-pin headers illustrated below carry signals that are made available to the system designer to
help with integrating system security. For example, the intruder alert signal on P18 can be routed to the
user-supplied system monitoring software via an internal chassis cover switch. If the cover is removed, the
switch opens and the user-supplied monitoring software registers a change in state of the intruder alert
signal. The monitoring software can send a signal to header P20 to sound the internal speaker alarm. See
Chapter 1 for the P18 and P20 pin-out details.
Optional IPMI and TPM 1.2 Headers
P23 is a 20-pin header that provides various IPMI signal connections for optional IPMI system
implementations. The hardware hooks to support IPMI are available on the motherboard; however, user-
supplied application software and an operating system that is IPMI aware must be available.
Header P13 is a two-pin header that will provide access to a future-use TPM General Purpose I/O (GPIO)
signal. Contact Trenton if your system requires this optional GPIO signal for your trusted computing
application.
The illustration below shows the location of headers P23 and P13. See Chapter 1 for the pin-out details of
P23 and P13.
