Built-in Self Test (BIST)

Zircon Lite does a BIST after resetting and displays the result on the
Diag LEDs (see "Understanding the Diag LEDs" on page 212) if an error
occurs. The following items are checked:
• Accessibility of SEL device
• Accessibility of FRU device
• Accessibility of SDR Repository (read only)
• Viability of Hardware Management Controller (HMC) firmware
• HMC hardware problem (general HMC failure)

Sensor Scan

Voltages, temperatures, fan tachometers, processor-related items, and
chassis intrusion are scanned
Voltages
Pin 10 of Winbond W83782D is be used as a 2.5 V reference. This voltage
is used to calibrate all of the voltage readings in Table 5-1
