This configuration supports fan redundancy.
Fan mode behavior
• In nonredundant fan mode, a fan failure or a missing fan causes:
◦ The system Health LED to flash amber.
◦ The operating system to orderly shutdown.
• In redundant fan mode:
◦ A fan rotor failure will switch the system to nonredundant fan mode.
This change is indicated by the Health LED flashing amber. The system continues to operate normally in this
mode.
◦ A second fan rotor failure or a missing fan causes the operating system to orderly shutdown.
Installing a fan
This server supports redundant fans to provide suicient airflow to the system if a fan rotor fails.
