The server supports redundant hot-plug fans (" Fan locations " on page 21 ) to provide proper airflow to the
server if a primary fan fails.
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.
IMPORTANT: Remove and replace one fan at a time. If the system detects two fan failures in
the same zone, the server shuts down to avoid thermal damage.
