Removing and Replacing the I/O Fan Module
There are five individual I/O Fan Modules located in the center of each SD32000 cabinet. They are labeled 0
to 4 and are easily replaced from the front of the cabinet. See Figure 3-17.
I/O fan failures are detected by logic on the (UGUY) within the cabinet. A chassis code is generated with error
data identifying the type of fan (IO or blower) and its physical location within the cabinet (fan number). This
event is relayed to the MP and reflected to all partitions within the complex via their console interface.
