Removing a Fan Module

About this task

The fan module is designed to be removed and replaced while the system is operating without presenting an electrical hazard or damaging the system.

CAUTION:

The IBM Storage Networking SAN c-type Family 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. However, the switches will shut down sooner if the major temperature threshold is exceeded.

Warning:

While removing the fan module, keep your hands and fingers away from the spinning fan blades. Let the fan blades completely stop before you remove the fan module. Statement 258

To remove an existing fan module, follow these steps:

Procedure

  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.
  2. Holding the handle, pull the module out of the chassis.
    CAUTION:

    Do not touch the electrical connectors on the back side of the module and prevent anything else from coming into contact with and damaging the connectors.

  3. Insert a fan blank module, as shown in Figure 1 if you do not have a new fan module.
