Hot-plugging a Front System Fan

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

CAUTION: Use caution when handling the fan until the fan blades stop spinning.

NOTICE: For proper cooling and airflow, do not operate the server with the cover removed for more than four minutes. Do not leave the chassis cover open or a system fan removed any longer than necessary; system cooling could be reduced.

NOTICE: The system fans are hot-pluggable. To maintain proper cooling while the system is on, replace only one fan at a time.
