NOTE: Under normal operating conditions, the fan modules operate at a moderate speed.
Temperature sensors in the chassis monitor the temperature within the chassis. The system
raises an alarm if a fan module fails or if the ambient temperature inside the chassis rises above
the acceptable range. If the temperature inside the chassis rises above the threshold temperature,
the system shuts down automatically.

PTX1000 Fan Module LEDs

The PTX1000 has status LEDs for each fan module on the left side of the corresponding fan module slot.
Figure 16 on page 39 shows the location of the LED next to the fan module on the PTX1000 FRU panel.
