Cisco 7600 Internet Router Components

Power Supply Fan Assembly

The power supplies have a built-in fan; air enters the front of the fan (power-input end) and exits through the back. An air dam keeps the airflow separate from the rest of the chassis, which is cooled by the system fan assembly.

To replace a power supply, see the “Removing and Replacing the Power Supply” section on page 5-2.
