Note
Replace a Fan Module
The Cisco 8608 router uses eight fan modules (8608-FAN) but it can operate with seven fan modules while
you replace one. When you remove one fan module, the other fan modules speed up their fans to maintain
the designed airflow.
The fan module is designed to be removed and replaced while the system is operating without presenting an
electrical hazard or damage to the system. Please keep the replacement fan modules ready prior to attempting
this task.
Use caution when handling the Fan Spinner. A fully loaded Fan Spinner (with fans) weighs 17.5 lbs (7.94
kg). An empty Fan Spinner (no fans) weighs 12.3 lbs (5.58 kg).
Ensure to close both the ejector levers at the same time so that the Fan Spinner sits properly in the slot.
Tighten the captive screws on the Fan Spinner within 10 seconds. If you can't replace an Fan Spinner within
three minutes, we recommend that you leave the Fan Spinner in the chassis until you are ready to replace it.
