Redundant Hot-Plug Fan Option 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 two fan zones: processor and power supply.

Redundant Hot-Plug Fan Option
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 two fan zones:
processor and power supply.
In the standard configuration, five fans cool the server: fans 1, 3, 5, and 7 in the
processor zone, and fan 9 in the power supply zone.
For the redundant configuration, fans 2, 4, 6, 8, and 10 are added to back up the
primary fans. This allows the server to continue operation in non-redundant
mode with one fan failure in either zone.
The server shuts down in the following scenarios:
