Redundant Hot-Plug Fans

The server supports redundant hot-plug fans to provide proper airflow to the
system if a primary fan fails. The server airflow is divided into three zones:
processor, I/O, and power supply. Shared fans 4 and 7 each provide airflow for
two zones. If a shared fan fails, the failure is experienced in both zones.
In the standard configuration, five fans cool the server: fans 2, 4, 5, 6, and 7 in
the processor zone; fan 4 in the I/O zone; and fan 7 in the power supply zone.
For the redundant configuration, fans 1, 3, and 8 (one fan per zone) are added to
cool the server. This allows the server to continue operation in non-redundant
mode if only one fan fails per zone.
