Notes:
• For server models installed with Intel Xeon 6144, 6146, 6154, 8168, 8180, and 8180M
processors, fan rotor redundancy function is not supported. If one fan rotor fails, the server
performance will be degraded.
• If your server comes with only one processor, five system fans (fan 1 to fan 5) are adequate to
provide proper cooling. However, you must keep the locations for fan 6 and fan 7 occupied by a
fan filler to ensure proper airflow.
