23. Power up the server (on page 17 ).
24. Run RBSU and enable the Optional PCI-X Riser Fan Monitoring setting. Enabling this option provides
health monitoring of the riser fans ("

Redundant fan assembly option
The server supports redundant fans to provide proper airflow to the system if a primary fan fails.
In the standard, non-redundant, configuration, fans 1 and 2 cool the server.
For the redundant configuration, fans 3 and 4 are added to back up the primary fans. This configuration
enables the server to continue operation in non-redundant mode, if a fan failure occurs. The following
rules apply:
• If one fan fails in non-redundant mode, the server shuts down.
• If one fan fails in redundant mode, the server converts to non-redundant mode.
• If two fans fail in redundant mode, the server shuts down.
To install the component:
1. Power down the server (on page 17 ).
2. Do one of the following:
o Open or remove the tower bezel, as needed (" Open or remove the tower bezel " on page 18 ).
o Extend the server from the rack (on page 17 ).
3. Remove the access panel (on page 19 ).
4. Remove the air baffle.
5. Install the redundant fan assembly, making sure the fans click into place.
NOTE: The fan configuration is redundant only when both fans are installed.
