or 12-LFF

configuration with

high-performance

fans

2 processors

For a single-processor configuration, excluding 24-SFF and 12-LFF configurations, four fans and two blanks

are required in specific fan bays for redundancy. A fan failure or missing fan causes a loss of redundancy. A

second fan failure or missing fan causes an orderly shutdown of the server.

For a dual-processor configuration or single-processor 24-SFF or 12-LFF configurations, six fans are required

for redundancy. A fan failure or missing fan causes a loss of redundancy. A second fan failure or missing fan

causes an orderly shutdown of the server.

High-performance fans might be necessary in 24-SFF and 12-LFF configurations for the following

installations:

•

Optional GPU riser installations

•

ASHRAE compliant configurations

For more information, see the Hewlett Packard Enterprise website.

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 BIOS/Platform Configuration (RBSU).
