Redundant hot-plug fans option

The server supports redundant hot-plug fans to provide proper airflow to the system if a primary fan fails.
In the standard, non-redundant, configuration, fans 1, 2, and 3 cool the server.
For the redundant configuration, fans 4, 5, and 6 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.
WARNING:
Remove watches, rings, or other metal objects.
•
Use tools with insulated handles.
•
Do not place tools or metal parts on top of batteries.
•
To install the fans:
Do one of the following:
1.
Open or remove the tower bezel, as needed
o
Extend the server from the rack (on page 22).
o
