Remove a Fan Module (Switch Chassis)

This procedure can be performed by a customer while the server is running if there are at least five of the six fan modules operating for each switch unit.


Note -  If you are removing fan modules to reinstall them in a new switch unit, remove them while the switch unit is installed in the chassis.

Caution

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 Module LED (Switch Chassis).

  2. Identify the faulty fan module that you want to replace.
  3. Take the necessary ESD precautions.

    See Prevent ESD Damage.

  4. Remove the fan module.

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