Fans
The server ships standard with six hot-plug fans installed.
In redundant mode:
• All six fans must be installed and operating.
• If one fan fails, the server is no longer in redundant mode.
• If two or more fans fail, then the server shuts down, and the health LED illuminates red.
To install the fans:
1. Extend the server from the rack ("Extending the server from the rack" on page 21).
