Remove a Fan Module (CMIOU Chassis)

This procedure can be performed by a customer while the server is running if there are at least seven operating fan modules.


Caution  -  This procedure requires that you handle components that are sensitive to electrostatic discharge. This discharge can cause server components to fail. When you unpack the replacement part, open the package on a grounded antistatic mat. Always use an antistatic wrist strap for hardware replacements.

  1. Determine which fan module requires service.

    See Identify Faulted Components and Fan LEDs (CMIOU Chassis).

  2. Take the necessary ESD precautions.

    See Prevent ESD Damage.

  3. Remove the fan module.

    You can remove a fan with the server running only if one fan module is faulty and if you have a replacement fan module. If more than one module is faulty, and the server is running, it will continue operating until a defined temperature is exceeded, at which point the server will perform a graceful shutdown.
