Fans 
The server supports redundant fans to provide proper airflow to the system when a primary fan fails. For more 
information, see "Redundant fan guidelines (on page 76)." 
 
 
IMPORTANT: Fan louvers must be present for the redundant configuration. Without the louvers, 
all four fans are nonredundant.
