Redundant hot-plug fans
The server supports redundant hot-plug fans to provide proper airflow to the system if a primary fan fails.
In the standard configuration, primary fans 2, 4, and 6 cool the server.
For the redundant configuration, fans 1, 3, and 5 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 Hot-Plug Fan locations (" Fan locations " on page 25 ).
WARNING: To prevent personal injury from hazardous energy:
•
Remove watches, rings, or other metal objects.
•
Use tools with insulated handles.
•
Do not place tools or metal parts on top of batteries.
Installing hot-plug fans
Redundant hot-plug fans can be inserted at any time, including when the server is operating.
For full redundancy, all fans must be installed.
