The fan modules are hot-swappable and can be replaced when the device is operating. After you have
identified the faulty fan assembly, follow this procedure to replace the fan:
1. Press the release tab on the right side of the fan module and pull the module from its slot.
2. Set the faulty fan module aside.
3. Remove the new fan module from the packaging.
4. Align the new fan module with its open slot, and then slide the unit in until it is seated in the connector.
After you insert the fan module, the system verifies the fan speed.
