CAUTION:

To avoid damage to server components, fan blanks must be installed in fan bays 1

and 2 in a single-processor configuration.

The only two valid fan configurations are listed in the following table.

For a single-processor configuration, 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.
Installing more than the required number of fans in a single-processor configuration is not a supported

configuration.
For a dual-processor configuration, 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.
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, HP 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 RBSU, HP 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 RBSU.
