• Chassis intrusion header (2-pin CHASSIS)
This header is for a chassis-mounted intrusion detection sensor or switch. Connect one
end of the chassis intrusion sensor or switch cable to this header. The chassis intrusion
sensor or switch sends a high-level signal to this connector when a chassis component
is removed or replaced. The signal is then generated as a chassis intrusion event.
20. 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 helps enhance network security,
protects digital identities, and ensures platform integrity.
The SPI_TPM module is purchased separately.
