Cisco 7505 Airflow Considerations

In the Cisco 7505, six individual axial fans draw cooling air through the chassis interior to maintain an
acceptable temperature for the internal components. The fans draw air in through the inlet vents on the
side of the chassis opposite the fans, across the processor modules and other internal components, and
through the exhaust vents adjacent to the fans.
The sides of the chassis must remain unobstructed to ensure adequate airflow and prevent overheating
inside the chassis. A temperature sensor on the RSP monitors the internal air temperature. The power
supply has two fans for cooling.
