Redundant cooling fan modules: The subsystems are equipped with two redundant, hot- swappable,
Detecting a failed cooling fan module: If a cooling fan module fails, you can be notified of the failure by the LED located at the back of the module, an audible alarm, the terminal event prompts, the Bosch RAIDWatch Panel View, or through the various methods by the Configuration Client utility.
Replacing a cooling fan module: Once you are notified that a cooling fan module has failed, it should be replaced as soon as possible. A failed cooling fan module should only be removed from the subsystem when you have an immediately available replacement module that can be installed as soon as the failed cooling fan module has been removed.
CAUTION!

The latches at the back of the cooling fan module secure the cooling fan module into the enclosure. If these latches are broken, the warranty on the cooling fan module will be void.
Although the cooling fan modules are fully redundant, it is not advisable to run the sub- systems with any of the cooling fan modules missing. Whenever a cooling fan module fails, the system is at risk of sustaining irreparable damage.
Keep a failed module in its enclosure bay until a replacement unit is in hand.
6.6.2Replacing a Cooling Fan Module
The cooling fan modules are secured to the chassis with two black latches located on the rear of the module. To replace the cooling fan module, please follow these steps:
1. To remove the cooling fan module: Squeeze both side latches towards the center of the cooling fan module and gently withdraw the cooling fan module from the subsystem by gently pulling on the silver handle at the bottom. (See Figure 6.6).

CAUTION!
Forcing or slamming a module into place can damage the connector pins on the module itself or that on the subsystem backplane.
2.Install the new cooling fan module: Line the new module up with the slot into which it will be inserted and then gently push it into the chassis. The latches will hold the module in place.
