System Health Support

The super I/O provides an interface via GPIOs for BIOS and system management firmware to
activate the diagnostic LEDs, the FRU fault indicator LEDs for processors, FBDIMMS, fans, and
the system status LED. See section 7 for the location of the LEDs on the workstation board.
The super I/O provides PMW fan control to the system fans, monitors tach and presence signals
for the system fans, and monitors server board and front panel temperature.

Trusted Platform Module (TPM)

The TPM 1.2 component is specifically designed to enhance platform security above and
beyond the capabilities of today's software by providing a protected space for key operations
and other security critical tasks. Using both hardware and software, the TPM protects encryption
and signature keys at their most vulnerable stages — operations when the keys are being used
unencrypted in plain-text form. The TPM is specifically designed to shield unencrypted keys and
platform authentication information from software-based attacks.
