Processor and Voltage Regulator LEDs
The Desktop Board contains two red LEDs (see Figure 6) that indicate the status of the
board’s voltage regulation circuitry and the processor:
• The Processor LED (Figure 6, A) indicates an e
levated temperature on the
processor that could affect performance.
• The Voltage Regulator LED (Figure 6, B) indicates an elevated temperature in the
processor voltage regulator circuit that could affect performance.
