Unscrew and remove the four screws that secure the drive cage to the chassis and remove the SAS

System fans

The server supports redundant hot-plug fans to provide proper airflow to the system if a primary fan fails.

In the standard configuration, three fans cool the server: fans 1, 3, and 5.

For the redundant configuration, fans 2, 4, and 6 are added to back up the primary fans. This

configuration allows the server to continue operation in non-redundant mode, if a fan failure occurs.

For fan locations, refer to "Identifying hot-plug fans ("Identifying redundant hot-plug fans" on page 73)."

All fans are identical. This procedure can be used for any of the six fan positions.

To remove the component:

1. Unlock and open the front bezel ("Front bezel" on page 19) (tower servers only).

2. Extend or remove the server from the rack ("Extending the server from the rack" on page 16).

3. Remove the access panel ("Access panel" on page 20).
