CAUTION: To avoid damage to server components, fan blanks must be installed in fan bays 1 and 2 in a single-processor CAUTION:
configuration.
CAUTION: To avoid damage to the equipment, do not operate the server for extended periods of time if the server does CAUTION:
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.
One-processor configuration One-processor configuration
Fan bay 1 Fan bay 1 Fan bay 2 Fan bay 2
Fan blank Fan blank
Two-processor configuration Two-processor configuration

The loss of a single fan rotor (one standard fan) causes loss of redundancy. The loss of two fan rotors (two standard fans or one high
performance fan) causes the server to initiate a shutdown.
The high performance fans are used for 8 SFF +2 SFF NVMe and 10 SFF drive configurations when NVMe drives are installed in the
server. They are also required for ASHRAE-compliant configurations. For more information on ASHRAE-compliant configurations, see
the Hewlett Packard Enterprise website https://www.hpe.com/servers/ASHRAE
The server supports variable fan speeds. The fans operate at minimum speed until a temperature change requires a fan speed increase to
cool the server. The server shuts down during the following temperature-related scenarios:
At POST and in the OS, iLO performs an orderly shutdown if a cautionary temperature level is detected. If the server hardware
detects a critical temperature level before an orderly shutdown occurs, the server performs an immediate shutdown.
When the Thermal Shutdown feature is disabled in the BIOS/Platform Configuration (RBSU), iLO does not perform an orderly
shutdown when a cautionary temperature level is detected. Disabling this feature does not disable the server hardware from
performing an immediate shutdown when a critical temperature level is detected.
CAUTION: A thermal event can damage server components when the Thermal Shutdown feature is disabled in the CAUTION:
