How to Install a Fan Module Controller Board


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.

An animation of the procedure to install a fan module controller board is available. See animation showing fan module controller board installation.

Before You Begin

  1. Prepare the server for service. See How to Prepare for Service.
  2. Access the back of the server.
  3. If you are replacing an FB, see How to Remove a Fan Module Controller Board.
  4. Use the handle to insert the FB into the server (1).

    Ensure that the connector on the FB engages with the connector on the SAM.

  5. To secure the FB assembly, fully tighten the green captive screw.
  6. Orient the fan shelf with the green release tab facing upward.
  7. To install the fan shelf, align it with the guides in the fan bay and slide it in until it locks into place (2).

    This action creates a click sound as the shelf locks into place.

  8. Install the FMs. See How to Install a Fan Module.
