    Installing and Removing Fan Modules This section provides instructions for installing and removing the fan modules for the Cisco MDS 9148T switch. You can replace one of the four fan modules even when the switch is operating so long as you perform the replacement within one minute of removing the old fan module.

  • Page 20: Installing A Fan Module

    Caution The Cisco MDS 9000 Series Switches have internal temperature sensors that can shut down the system if the temperature within the chassis exceed certain safety thresholds. To accurately monitor the system temperature, the temperature sensors require sufficient airflow through the chassis. In the event that a fan module is removed from the chassis and the airflow is reduced, the system will bypass the temperature sensor information and shut down after five minutes to prevent undetected overheating.
  • Page 21 Installing the Cisco MDS 9148T Switch Removing a Fan Module To remove an existing fan module, follow these steps: Step 1 On the fan module that you are removing, press the two sides of the fan module handle next to where it connects to the fan module and pull on the handles enough to unseat it from its connectors.
