Redundant fan guidelines

The server supports redundant fans to provide proper airflow to the system when a primary fan fails.
In the standard, nonredundant configuration, fans 2, 3, and 4 cool the server.
For the redundant configuration, fan 1 and four fan louvers are added to back up the primary fans. This
configuration enables the server to continue operation in redundant mode, when a fan failure occurs. In a
redundant fan configuration:
•
If one fan fails, then the other three fans provide airflow.
•
If two fans fail, then the server shuts down.
IMPORTANT: Fan louvers must be present for the redundant configuration. Without the
louvers, all four fans are nonredundant.
NOTE: If your system is already installed with four fans, store the fan that is included in this kit
as a spare.
