Hot-plug fans
CAUTION:
To avoid damage to server components, fan blanks must be installed in fan bays 1 and
2 in a single-processor configuration.
CAUTION:
To avoid damage to the equipment, do not operate the server for extended periods of
time if the server does not have the optimal number of fans installed. Although the server might
boot, Hewlett Packard Enterprise does not recommend operating the server without the required
fans installed and operating.
The valid fan configurations are listed in the following tables.

The loss of a single fan rotor (one standard fan) causes loss of redundancy.
The server supports variable fan speeds. The server shuts down during the following temperature-related
scenarios:
• At POST, BMC performs an orderly shutdown if a cautionary temperature level is detected.
• In the OS, BMC performs an orderly shutdown if a shutdown point is triggered. The actual shutdown
behavior will be impacted by the OS settings.
High-performance fans
High-performance fans are used for 8SFF +2SFF NVMe and 10SFF drive configurations when NVMe
drives are installed in the server.
