power redundancy, it boots the system after issuing a warning by illuminating the Warning LED. Hot swapping is not possible in the absence of redundant power.

Redundant Cooling Fan Modules

The Cooling Fan Modules cool the system with variable speed fans, and are installed redundantly, as illustrated in Figure 27. The fans cool the system by pulling air from the front of the chassis to the back. The modules can be hot-plugged, enabling a failed Cooling Fan Module to be replaced without disrupting system operations. Cooling Fan Modules support the following functions:

•Control rotation

•Detect abnormal rotation

•Indicate the faulty location with LEDs

•Built-in fuse
