How to Remove a Fan Module


Caution - Potential for system over-temperature and component damage. Do not attempt to operate the system with insufficient cooling. Maintain the integrity of a properly functioning cooling system by immediately replacing nonworking components and ensuring unobstructed airflow.

Note - The fan module is a hot-plug component.

An animation of the procedure to remove a fan module is available. See animation showing fan module removal.

Before You Begin

  1. If necessary, prepare the server for service. See How to Prepare for Service.
  2. Access the back of the server and identify the fan module (FM) that you need to replace.
  3. To release the FM handle, gently squeeze at the two green-colored release points and pull the handle outward to its fully opened position.

  4. To remove, pull the FM out of the server.


    Caution - Server over-temperature condition. When a fan module is removed, the airflow vanes in the subassembly module automatically close to maintain the integrity of the server cooling system. Do not defeat the purpose of the airflow vanes.

  5. If you are replacing the fan module, see How to Install a Fan Module.
