Pedestal Status and Power LEDs
The pedestal is equipped with two front panel LEDs that monitor the following
error conditions (Figure 3–1):
■ A power supply fan that is not operating
■ An over-temperature condition

■ External fault conditions
■ Controller faults
When the pedestal is operating properly, the green power LED is on and the
amber pedestal fault LED is off. Also, the green power supply LED on the rear
of each power supply is on.
